CHIP MILL ANNOTATED BIBLIOGRAPHY
Introduction
This annotated bibliography represents a broad-based and balanced
compendium of scientific research articles that address harvest
practices and their impacts on forests, fish, wildlife, soils
and water resources. Sources of the literature search included,
but were not limited to, The University of Missouri Library, OVID,
Internet web sites, The School of Natural Resources (SNR) faculty,
The United States Forest Service North Central Research Station
in Columbia, MO, SNR theses and dissertations, personal communications
with professionals in the natural resources field, communication
with various state, federal, and university personnel in those
states where chip mills are located.
Rather than an annotation which is usually shorter in length,
we have opted to present a full abstract for each article. An
abstract is more useful because it outlines the scope of the work
and the major findings of the research.
This bibliography contains scientific information that we deemed
reputable and relevant to Missouri's forest habitat types. It
is by no means a complete bibliography. Rather, it should be viewed
as a work in progress. As study reports and articles on chip mills
become available they can and should be entered into the database.
In the interests of time, and due to manpower constraints, we
limited our search to those states listed in the project agreement
under "Scope of Work". There were some articles that
we requested through a particular referral source but did not
receive them. Newspaper articles and unsubstantiated commentary
that were not peer reviewed by professionals in the field of natural
resources were not included. In some cases research was not included
if a complete citation was not given. One can oftentimes complement
their literature search by checking the literature cited at the
end of the research article for more articles dealing with the
specific topic of interest.
Bibliography layout
At the beginning of the bibliography there is a table of contents.
Within the table of contents, the basis for the organization of
the research literature revolved around two points; one was the
category of potential environmental impacts as listed in the Governor's
Executive Order 98-16. The other was a natural division or categorization
of literature that surfaced as we conducted our search. These
subdivisions of information are listed in alphabetical order.
Within each of the subdivisions will be found research articles
and other scientifically reputable information along with the
citation and annotation for each. In addition, there is a 3.25-inch,
2MB computer diskette located in a pocket located inside the front
cover of the bibliographic report. This computer diskette contains
a complete listing of the database. This database was completed
using Corel's WordPerfect 8.0. Using edit functions within WordPerfect
one can do a search for keywords. Along with the bibliography
report we have included a copy of each research article, report,
and bulletin. These articles are arranged in alphabetical order
according to the name of the lead author.

BEST MANAGEMENT PRACTICES (BMPs)
Adams, T.O., and D.D. Hook. 1994. Compliance with silvicultural
best management practices on harvested sites in South Carolina.
Southern Journal of Applied Forestry. 18(4): 163-167.
ABSTRACT: One-hundred-seventy-seven harvested sites in South
Carolina were evaluated for compliance with Best Management Practices
(BMPs). South Carolina Forestry Commission (SCFC) foresters evaluated
the roads, road stream crossings, streamside management zones,
harvest operations, and log decks. In addition, each site was
evaluated for overall BMP compliance, which was based on the level
of both off-site and on-site impacts. Overall BMP compliance was
84.7%. Compliance was highest for log decks (97.7%), roads (92.0%),
and harvest operations (89.8%) and lowest for streamside management
zones (72.4%) and road stream crossings (41.7%). Nineteen variables
were analyzed to determine their influence on BMP compliance.
Two variables were responsible for the 27sites with inadequate
ratings: (1) the presence of perennial and intermittent streams,
and (2) logging under wet soil conditions. Compliance did not
differ significantly among landowner categories or physiographic
regions. To improve BMP compliance, landowners should identify
sensitive sites and take adequate steps to protect them during
timber harvesting.

ABSTRACT: Assesses North Carolina's compliance with forestry
BMPs, including compliance in the areas of roads, buffer strips,
skid trails and water bars.
Based upon findings in this study, compliance with North Carolina's
forestry BMPs and FPGs can be increased and improved in the following
ways:
1. BMP workshops, such as the Prologger workshops given by the
North Carolina Forestry Association (NCFA) and this division,
should continue and possibly increase in frequency.
2. Education should focus on pre-harvest planning and how to avoid
sensitive areas on harvest sites. Also, the use of correctly installed
water bars and adequate SMZs should be strongly stressed expressed
to loggers and timber buyers.
3. A statewide database should be created to better monitor the
level of forestry BMP compliance.

Best Management Practices. Northern Journal of Applied Forestry.

ABSTRACT: A 39 ha gauged watershed located in north-central
West Virginia near Parsons was cut to a 35.5cm stump diameter
and logged using wheeled skidders to evaluate the effectiveness
of West Virginia's Best Management Practices (BMPs). Roads initially
occupied 10.6% of the watershed, but this percentage is decreasing
as much of the original road prism reverts to forest. Reducing
basal area by 44% in stems 2.54 cm dbh and larger had a negligible
effect on maximum growing season stream temperatures, apparently
because the stream remained shaded by residual trees and understory
shrubs growing along it. Both growing season peakflows and total
stormflow had small but significant increases due to treatment.
Dormant season stormflow did not increase significantly. Although
mean monthly exports of suspended sediment doubled the first year
when the area was being logged, they remained within the range
reported for carefully managed areas in the East. Sediment exports
returned to pretreatment levels by the third post treatment year.
Long-term projections of current exports rates indicate that sediment
exports from harvesting operations (3 entries) during a 100 yr
rotation will account for less than 5% of the total sediment exported
from the study watershed. Nitrate exports increased significantly
during most of the monitored post treatment years, but fertilizer
applied to the roads during grass seeding is believed to have
contributed to these increases. Actual concentration values remained
low, with maximum concentrations well below standards for potable
water. Calcium concentrations also increased during most years,
but road liming during seeding probably was responsible for most
of this increase. The BMPs used in this study were effective in
minimizing adverse impacts to soil and water resources.

CHIP MILLS
Gray, J., and J. Guldin. 1997. Hardwood chip export mills
in Arkansas - implications for sustainability. Paper presented
at the Symposium on Arkansas Forests - a conference on the results
of the recent Forest Survey of Arkansas. May 30-31, North Little
Rock, AR.
ABSTRACT: Two new hardwood chip export mills (HCEM's) recently
began operating in west-central Arkansas, and a third is planned.
Together, they will require 1.1 million tons of non-hickory hardwood
roundwood annually, primarily from the nonindustrial private sector.
Overall, total physical and operable growth surpluses could support
the new sector, but purchasable surpluses are barely adequate
now and may be less than adequate by 2005. The HCEM's will generate
about 630 direct and indirect jobs and $16.75 million in yearly
wages and stumpage payments. However, if all of the new demand
is met by unsightly harvesting methods, tourism related job losses
after 15 years could offset HCEM-generated employment. Because
HCEM's will increase competition for hardwood, some small sawmills
may go out of business, although the turnover of small sawmills
was high even before HCEM's entered the market. The HCEM market
for small hardwoods is less than ideal, but these mills can process
"rough" and "rotten" trees. HCEM harvesting
is generally not good forestry; to date, it has tended to take
the best trees and leave the worst. This could improve if landowners
were better informed and willing to reinvest following harvest.
The effects of HCEM's on Arkansas hardwood forests as a whole
are not expected to be great. Although protection of soils and
water quality has been inconsistent, the new sector appears to
be committed to provide such protection on lands they harvest.
The authors present six recommendations designed to promote a
positive effect of new sector operations on the sustainability
of timber resources and other forest values.

Smith, D. 1997. Chipping forest and jobs: A report on the
economic and environmental impacts of chip mills in the Southeast.
The Dogwood Alliance, P.O. Box 4193, Chattanooga, Tennessee. 82p.
ABSTRACT: The recent proliferation of chip mills in the southeastern
U.S. is causing unprecedented forest destruction, degrading not
only water quality, wildlife threatened and endangered species
and forest health, but also our local economies. Last year alone,
an estimated 1.2 million acres were cleared to feed the 140 chip
mills in the region. Chip mill operations perpetuate short cutting
cycles, thereby reducing native forest ecosystems to fiber farms.
Removals of softwoods throughout the South have already exceeded
growth, and experts predict a shortage of hardwoods within the
next two to ten years. In addition, experts predict that by the
year 2020, 70% of the native pine forests in the South will have
been converted to pine plantations to meet increases in industry
demand for softwood fiber.
This report published by the Dogwood Alliance and the Native Forest
Network documents the trends in forestry, with special focus on
the pulp and paper industry. They present many impacts which chip
mills potentially will have on the environment, communities, forestry
and related jobs, as well as effects on private landowners. Also
presented are their solutions to the chip mill problem.

ABSTRACT: The environmental consequences of denying, approving,
or approving with mitigation measures one or more chip mill barge
terminals between river miles 412 and 424 of the Tennessee River
are analyzed. The impact analysis includes both localized (on-site)
and procurement area(off-site) impacts. Localized impacts are
those that are directly or indirectly associated with construction
and operation of a barge terminal, use of TVA land for access
to the barge terminal, and use of adjacent private land for a
chip mill. Procurement area impacts are associated with timber
harvest. After weighing the potential benefits of the pending
requests with the likelihood of substantial, cumulative localized
impacts and the risk of significant harvesting-related impacts,
TVA's preferred alternative is denial of all proposed actions.

Cubbage, F.W., and D.D. Richter. 1998. Cooperative Research
Proposal: Economic and ecologic impacts associated with wood chip
production in North Carolina. The Southern Center For Sustainable
Forests. (Unpublished; Study in progress).
OBJECTIVES: The research project will be developed as an integrated
study of economic and ecologic impacts of wood chip production
in North Carolina. The economic component will examine direct
financial impacts and broad economic issues of wood chip production.
It will employ large scale economic and timber supply models to
examine:
(1) the impacts of wood chip production on timber supply;
(2) the effect of wood chip production on wood-based manufacturing
firms;
(3) the effects of improved timber markets for forest landowners;
(4) the market and nonmarket impacts on economically efficient
forest management practices and on forest conditions; and
(5) the impacts of wood chip production on local economies, infrastructure,
and communities.
The ecologic component will evaluate the effects of expanded wood
chip production on individual forest stands and regional landscapes
by using literature reviews, field surveys, and models to examine:
(1) how wood chip production alters ecology of forest management
practices in North Carolina;
(2) direct, indirect, and cumulative effects of wood chip production
on forest structure, plant and animal communities, soil erosion
and fertility, and water quality;
(3) the impacts of wood chip mills on stormwater and waste water
runoff from processing facilities; and
(4) evaluating forest management options for assuring sustainability
of North Carolina's forest resources as harvest pressures continue
to mount, and as forest values continue to increase.

Tennessee Forest Management Advisory Panel. 1998. Final
Report. Report to: Governor , Commissioner of Agriculture, Tennessee
Forestry Commission, and Tennessee General Assembly. 66p.
ABSTRACT: The Panel was established by Senate Joint Resolution
No. 230. The charge was to evaluate and recommend appropriate
policy and operational programs that promote forest sustainability
and sound stewardship on Tennessee forest lands. Such recommendations
were to include guidelines for the management of state forest
lands, and programs and services to all forest landowners. For
all recommendations proposed, the Panel sought and utilized scientific
and authoritative data to reach its conclusions. Suggestions are
also made for funding these recommendations. Great strides were
made by the Panel in balancing widely divergent resource needs
by using widely diverse interest groups to develop consensus recommendations.
The Panel identified an array of important issues, many being
too complex to resolve in a short period of study. The recommendations
of the Panel, if implemented, can be the forerunner of an ongoing
process leading to the achievement of forest sustainability in
Tennessee.
Keywords: sustainability, Tennessee forest lands.

losses from forest management: mechanical vs. chemical site preparation
after clearcutting. Journal of Environmental Quality. 15(4):
413-416.
ABSTRACT: The comparative effects of mechanical and chemical
site preparation on water yields and sediment losses following
forest clearcutting were evaluated over a 4-yr period in the Athens
Plateau area of southwestern Arkansas. After 1 yr of pretreatment
measurements, three forested watersheds were clearcut and the
residual vegetation and debris were sheared and windrowed but
not burned. Three watersheds were clearcut in a similar manner,
but received chemical site preparations. Residual trees on two
watersheds were injected with 2-4,D amine; the third watershed
was serially sprayed with a mixture of Tordon* (active ingredient;
picloram [4-amino-3,5,6-trichloropicoline acid]) and GarlonR (active
ingredient; triclopyr [3,5,6-trichloro- 2-pyridinyloxy-acetic
acid]). Three additional watersheds were left undisturbed for
controls. Mean annual sediment losses on the mechanically, site
prepared watersheds during the first post treatment year were
significantly higher than those from either the chemically site
prepared watersheds or controls. Chemical site preparation did
not significantly increase sediment losses. Although 2nd yr losses
for the mechanical site preparation and control treatments doubled
over 1st-yr levels, so significant treatment effect was detected
for either site preparation treatment. Third-year losses decreased
below 1st-yr losses for all treatments but not to pretreatment
year levels. The relatively sharp declines in sediment losses
during the third post treatment year were attributed to rapid
regrowth of natural vegetation on the sites.

of erosion control techniques on forest roads. American Society

ABSTRACT: The cutslope and fillslope on a newly constructed
forest road on the Talladega National Forest near Heflin, Alabama
were treated with three erosion control techniques: wood excelsior
erosion mat, native grass species, and exotic grass species. Bare
soil plots were used as the experimental controls. Total sediment
yield was measured during the period 21, September 1995 to 18,
March 1996. A randomized complete block design was used to evaluate
treatment methods on the basis of sediment yield and runoff volume.
No significant difference in sediment yield was found from the
fillslope among the treatments. However, on the cutslope significant
differences were detected among all treatments. The erosion mat
treatment was most effective in mitigating erosion losses with
a 98% reduction in cutslope sediment yield and 88% reduction in
fillslope sediment yield.

ABSTRACT: In the steep terrain of the Appalachian Mountains
much damage to forest streams is caused by erosion on logging
roads. Muddy water that is unsuitable for fish, swimming, or human
consumption often can be traced to these eroding roads. This paper
has been prepared to sum up what land managers know about preventing
and controlling erosion on logging roads in the Appalachians.
This paper covers the process of design, construction of and maintenance
of logging roads, and ends with the proper care of that road following
the logging operation.

harvest and site preparation effects on erosion and sedimentation
in the Ouachita Mountains. Journal of Environmental Quality.
17(2): 219-225.
ABSTRACT: Soil erosion and sedimentation effects of three silvicultural
treatments-- clearcutting, selection cutting and no disturbance
(control) were compared in a replicated small watershed study
conducted in the Ouachita Mountains of Arkansas on shallow soils
derived from sandstones and shales. Clearcutting significantly
increased annual sediment yields over selection and control treatments
in 1981, the first year, after treatment but not in 1982 or 1983.
Clearcut to control sediment yield ratios were 20:1, 6:1, and
2.6:1 in 1981, 1982, and 1983, respectively. First-year sediment
losses from clearcuts averaged 237 kg ha-1. Stream channels were
stable, but they still may have been the primary source of the
sediment losses. Erosion following harvest and site preparation
did not exceed estimates of long term soil formation rates. Long-term
soil losses were projected to average 70 kg ha-l yr-1 over a 35-yr
rotation period with clearcutting while control rates were projected
to average 50 kg ha-' yr-1. A comparison of soil losses measured
in this study with baseline rates and estimated soil loss tolerances
suggests site productivity need not be threatened by silviculturally
induced soil erosion. Suspended solids levels of storm flow were
less than 100, 50, and 20 mg L-1 at least 99, 98, and 97 % of
the time, respectively, across
treatments. Only at the 10 mg L-1 level was there a significant
total suspended solids time differential in watershed stormflow
between clearcut or selection cut and control treatments.

Journal of Forestry.
47(10): 671-677.
ABSTRACT: This paper provides an overview of what is known
about forest soil erosion in eastern United States. By most accounts,
erosion form undisturbed as well as carefully managed forest land
is 0.05 to 0.10 ton/acre/year; that is less than the geologic
norm (0.18 to 0.30) and far less than maximum tolerable rates
for agricultural land (1 to 5 tons/acre/year). Eroded material
is about equal parts of particulate and dissolved matter. Responsibly
managed timber harvest causes only minor increases in forest soil
erosion, usually from channels and logging roads, but irresponsible
timber harvest can increase erosion of particulate matter to unacceptable
levels.

land, geologic norm.

woodlands. Northern Logger and Timber Processor. 25(11): 4-5,

ABSTRACT: One of the few ideas that most people can agree upon
is that woodland is our surest protection against accelerated
soil erosion. People have concurred in this belief since history
began but our concept of how forests protect the soil is evolving
even now. A considerable part of this evolution is spanned by
my career with the U.S. Department of Agriculture. Three conclusions
are reached:
(1) Because overland flow rarely occurs in the eastern hardwood
forest, there is no mechanism to transport particulate matter
across the forest floor. Eroded material, consisting equally of
particulate matter and dissolved solids, originates primarily
in stream channels. This material averages about 0.05 to 0.10
ton per acre per year.
(2) Tree cutting does not cause overland flow so it has only a
negligible and temporary effect on soil erosion rates and on stream
pollution.
(3) Logging, especially in streams, can cause erosion rates to
increase greatly, but logging roads more frequently are sites
of accelerated erosion.

in the Eastern Hardwood forest. Southern Journal of Applied
Forestry. 2(3): 66-73.
ABSTRACT: For the eastern United States, there is overwhelming
evidence that neither the productivity of forest soil nor the
quality of forest water are substantially lessened during or after
responsibly managed harvest of wood products. Carelessness, however,
damages both resources. The key is forest roads; they cause little
adverse effect on soil or water given proper location, drainage,
traffic control, and maintenance. The public must better understand
that it bears much of the cost for these measures.

Hardwoods For. Conf. University of Missouri.

ABSTRACT: Disturbance of the vegetation, protective litter
layer and soil on a forested watershed during logging can lead
to localized overland flow and erosion. A paired watershed study
was initiated to the determine the effects of clearcutting on
runoff and sediment yield in the oak-hickory type of the Missouri
Ozarks. A network of 20 runoff plots was established in the logged
and undisturbed portions of both watersheds to identify the source
areas for surface flow and erosion. Plots were located so as to
sample a range of physiographic positions. Total storm runoff
and sediment yield have been inventoried for all precipitation
events since March, 1979 for each plot and related through multiple
regression analysis to a number of site factors. Precipitation
variables included total storm volume; average storms, maximum
5 minute and maximum 30 minute intensities; and canopy throughfall.
Other variables inventoried included surface soil cover, antecedent
surface soil moisture and plot location with respect to slope
percent, aspect and position. While data have been extremely variable
between storms and between plots, runoff for the clearcut areas
has averaged ten time greater than that for the undisturbed plots.
Moreover, sediment yield has been as much as 100 times greater
for the disturbed plots in the clearcut area. Additional research
will be required to more clearly define cause-effect relationships.
Although the influence of a number of storm and site related factors
on the surface runoff and sediment yield processes can be easily
observed in the field, and have often been empirically verified,
this study has demonstrated that, under certain circumstances,
the relationships between storm/site factors and runoff and sediment
yield are far from straightforward.

HISTORY AND ECOLOGY
Beilmann, A.P., and L.G. Brenner. 1951. The recent intrusion
of forests in the Ozarks. Annals of the Missouri Botanical
Garden. 38: 261-282.
ABSTRACT: Scanlan (1950), in writing of American forests, says:
"The lumber barons began to despoil and they did an excellent
job." This statement might correctly be applied to a specific
region but a lumber baron could not operate in a prairie region.
Seemingly, it cannot be applied at all to the eastern and northern
portions of the Ozarks. Within historic times this vast region
was a prairie, or at least park-like in that the trees were widely
spaced and confined to the water-courses and drainage-ways. The
logging operations which are now so much a part of the industry
of the Ozark region are but little more than a century old. The
loggers have been, and still are, cutting the first crop of trees
to mature there. In some sections any tree large enough to yield
a 2 x 4 is cut; and the region will be scoured again and again
for more trees of that size. However, there is evidence to show
that insufficient time has elapsed to develop a mature second
growth of either pine or hardwoods.
This paper gives an excellent recounting of the ecological history;
including fire, human settlement, soils, and vegetation and forest
coverage in the Ozarks.

ABSTRACT: Missouri's presettlement pine and oak-pine forest
once extended over six million acres. Today the pine and oak-pine
cover types occur on less than 400,000 acres. Between 1880 and
1920, some of the Nation's largest producing sawmills were operating
in Missouri's Eastern Ozarks region. A historic review of this
period's industrial and social activities toward the Ozark forests
illustrates how an area once dominated by pine was converted to
hardwoods.

Conserving biodiversity in managed forests. BioScience
41(6): 382-392.
ABSTRACT: Consensus is emerging among ecologists that biological
diversity will not be conserved effectively in natural reserves
alone(Wilcove 1989). The existing reserve network is too small,
major expansion is unlikely, and barriers to migration make species
in reserves especially vulnerable to global climate change(Westman
1990). Therefore, Harris(1984) recommends that the reserves be
complemented with a matrix of "seminatural" lands where
ecological principles are used to manage both for commodity production
and conservation of species diversity. The challenge now is to
design and effectively manage such multipurpose landscapes (Franklin
et al. 1986, Hunter 1990).
Studies of unmanaged forests teach us that natural disturbance
maintains structural complexity within stands and that this complexity
promotes plant and animal diversity. Attention to structural complexity
is a core concept of the "new forestry" now being advocated
in the coastal Northwest (Franklin 1989, Gillis 1990). Another
lesson from natural forests is that old growth is only one of
the common natural seral stages, and each stage provides important
and/or critical habitats to some plants and animals. Finally,
comparisons between natural and managed forests teach us that
native species diversity is influenced by the size, distribution,
edge characteristics, and dispersion of stands across landscapes.
They suggest that these lessons are not unique to the Pacific
Northwest.

and ecosystem health. Southeastern Center for Forest Economics

ABSTRACT: Economic valuations of changes in ecosystem health
can provide quantitative information for social decisions. However,
willingness to pay for ecosystem health may be motivated by an
environmental ethic regarding the right thing to do. Counter preferential
choices based on an environmental ethic are inconsistent with
the normative basis of welfare economics. In this paper, we examine
some of the characteristics of willingness to pay values elicited
using the contingent valuation method. Sequential contingent willingness
to pay values for different levels of protection of high-elevation
spruce-fir forests in the southern Appalachian Mountains were
elicited from a random sample of households along with socioeconomic
and other information. An empirical analysis indicated that willingness
to pay distributions and average willingness to pay did not vary
with the level of protection. We discuss various factors that
may explain our results including lexicographic preferences, low
marginal values, lack of instrument sensitivity, or misrepresentation
of the ecosystem services valued by the public. We conclude that
further theoretical development of the relation between ethical
motivations and economic value is warranted.

hardwood ecosystem. Forest Ecology and Management. 90(2,3):

ABSTRACT: Sustainable management of bottomland hardwood forest
ecosystems requires a knowledge of responses to management impacts,
including timber harvesting. The effects of clearcutting and partial
cutting on woody vegetation regeneration dynamics, surface and
groundwater quality, soil physical properties, and soil respiration
were tested in a bottomland hardwood ecosystem in southeastern
Texas, USA, through comparison with non-cut control areas. Overstory
removal only slightly affected composition of woody vegetation
regeneration 1 year after harvesting compared with pre-harvest
composition. Initial composition in both cutting treatments appeared
to be the strongest determinant of post-harvest composition, at
least for the first year after harvesting. There were few significant
differences in groundwater properties when harvesting treatments
were compared with control areas during a 17-month period following
harvest. Turbidity, temperature, electrical conductivity, dissolved
O2, NH4-N, and PO4-P of stream water did not vary significantly
among treatments. Slight decreases in total and macro porosity
were observed in association with higher bulk densities at 0-5
cm depth in the clearcut and partial cut treatments. Saturated
hydraulic conductivity values did not decline significantly with
treatment intensity. No significant differences among treatments
in measured soil physical properties were observed at 5- 10 cm
depth. Although in situ soil respiration increased with harvest
intensity, treatment had no significant effect on mineral soil
respiration. In summary, most variables showed only slight response
to harvesting, thereby indicating that harvesting practices can
be conducted with minimal initial impacts on measured response
variables.

ABSTRACT: Wild plants and animals can provide natural chemicals
and compounds for producing drugs and other products, information
and ideas for developing synthetic chemicals and compounds, and
genes for engineering plants and animals with desirable sets of
traits. Despite their value, wild species are threatened by destruction
of natural habitats. Because there are no property rights to wild
species or the genetic resources embodied in them, habitat protection
tends to be undervalued, particularly in developing countries.
However, contractual arrangements that allow these countries to
trade the right to collection of their wild genetic resources
in return for compensation could foster habitat protection in
the absence of such property rights.
Keywords: biodiversity, property rights, habitat.

ABSTRACT: Monitoring the health of reserve hardwood trees is
being performed as part of the Ecosystem Management Research Project
for shortleaf pine-oak forest types on the Ouachita and Ozark
National Forests in Arkansas. Results will provide information
about the success of retaining such trees and to provide guidelines
for selecting reserve trees in future operational harvests. Reserve
trees are mostly 10 to 12 inch d.b.h. codominant and intermediate
oaks. A suite of crown measurements (diameter, live crown ratio,
density, dieback, and foliage transparency) is being used to detect
significant changes in reserve tree health over time. Average
ratings for these indicators before harvest appear to be within
normal ranges for each species. Immediately after harvest, 16
to 62 percent of reserve trees had logging injury to the base,
crown, or both. Injury frequency generally increased with the
intensity of harvest cutting. Most injury was judged slight or
moderate in severity.
Keywords: injury, harvest intensity, health, crown, oak, shortleaf

ABSTRACT: Natural and geological processes have changed the
Southern Appalachian landscape repeatedly over millions of years.
About 12,000 years ago, humans arrived and became important agents
of change. The extent and degree of human influence increased
along with the population. Today, pressure remains intense on
the Southern Appalachian landscape and management issues bring
contention as different groups seek to use the region's resources
in different ways.

June 20-22, 1995. Asheville, NC. 1-6.
ABSTRACT: For as long as we have been collecting inventory
information, the southern timber inventory has been increasing.
In the last decade, however, softwood removals in the South have
exceeded growth. If current trends continue, hardwood removals
will exceed growth in about a decade. If availability and operability
constraints are considered, the supply situation looks even more
serious. These structural changes in the supply situation, coupled
with increasing demand on the resource have led to dramatic price
increases. This paper analyzes past trends and assesses the future
supply and price situation for the South. The potential effect
of intensive management on both regional supply and wood cost
will also be examined.

ABSTRACT: The 1987 Forest Survey of Mississippi shows a slight
increase in forest area and a substantial gain in hardwood inventory.
Hardwood gains, appearing in all diameter classes, suggest an
increase in quality but hardwood users generally believe quality
is declining. By our analysis, volume of top quality hardwood
declined while volume in other grades increased. Forest Survey
grading is conservative when compared with grades assigned by
a hardwood specialist. User constraints applied to the survey
data base severely limit the amount of "available" quality
hardwood. Forest Survey data are available so users can conduct
their own analyses.
KEYWORDS: forest survey, Mississippi, hardwood, grade.

ABSTRACT: The Forestry Division of the Missouri Department
of Conservation (MDC) contracted with the Department of Rural
Sociology in the College of Agriculture, Food, and Natural Resources
at the University of Missouri-Columbia to conduct and analyze
a survey of Missouri residents regarding a number of forest land
use and conservation knowledge issues. This project is a replication
of a 1993 study called the "Benchmark Survey" done by
MDC. As in 1993, the survey instrument dealt with a number of
forest use and management issues as well as several questions
related to Missouri citizens' environmental views. The survey
gave respondents the opportunity to state their opinions and perceptions
on such issues as the seriousness of a variety of environmental
problems, the value of forests in general and government-owned
forests in particular, their general knowledge of Missouri forests,
and the responsibility and duties of the Forestry Division of
MDC. The 1996 survey contains some slight modifications of the
1993 instrument which are noted in the final report.
A summary of respondents perceptions of Missouri forest and forestry
practices.

of southern hardwood logs for chips by species and size. In:
Proceedings of the 1992 Tappi Pulping Conference; 1992 November
1-5; Boston, MA. Atlanta, GA: Tappi Press. Book 1: 369-374.
ABSTRACT: Results of a woodyard study in northeast Mississippi
examining the effects of log size add hardwood tree species on
log utilization and chip quality are presented. Utilizations defined
as weight of a debarked log divided by the weight of the undebarked
log expressed as a percent. Utilization averaged 85.2 percent
for oaks, 79.2 percent for sweetgum, 85.0 percent for mixed species,
and 75.1 percent for hickories. Differences in utilization within
a species is attributed to log size and log breakage during debarking.
In the chip quality analysis, the highest percentage of acceptable
sized chips were associated with the 22.9 cm log diameter class
rather than with the larger 27.9 cm diameter class for the oak
and mixed species groups. For sweetgums, levels of acceptable
sized chips were not significantly different between the three
largest log diameter classes. Oversized chips were minimized with
the 22.9 cm log diameter class for the oaks, sweetgums, and mixed
species groups. Levels of fines and pin chip production varied
among the log diameter classes according to species group. In
hickories, the 27.9-cm log diameter produced the highest levels
of acceptable sized chips and lowest levels of fines, pins, and
oversized chips. Bark content for oak, sweetgum, and hickory species
were all under 1 percent of the total chip sample. Bark content
for the smaller diameter log, classes in the mixed species group
was over 3.5 percent.

production in Tennessee: Statistics, Effects, and Trends.

ABSTRACT: In 1989, about 2.7 million tons of timber were cut
in Tennessee to make woodchips for pulp and paper. Hardwoods comprised
about 1.1 million tons of this total. This resulted in over harvesting
in 17 counties statewide.
By 1996, the cutting of hardwoods for chips tripled to 3.3 million
tons, due to increased demand from existing mills and from twelve
new log export facilities. Total removals for woodchip production
reached 5.2 million tons.
In 1997-after the date of the most recent data used within this
report- three new high-capacity chip mills were located in Tennessee,
or were sourcing logs from Tennessee, and are expected to keep
forest consumption growing at a high rate. Over harvesting will
increase.
Projecting a modest growth rate of only half that of recent years,
about 6 million acres of trees (half of all Tennessee's forest
land) will be needed by the year 2016. This level of clearcutting
will doubtless have drastic effects on the hardwood industry.
Long-term effects on the health and productivity of Tennessee's
forests are unknown.

ABSTRACT: The National Forest Health Monitoring Program is
focusing on assessing the condition of our nation's forests in
response to the interests and concerns of the American people.
As a part of the program, this report was produced in an effort
to present information about forest condition and forest stressors
(insects, pathogens, weather, fire, and air quality) with respect
to major forest types. This document provides an historical perspective
on the influence of the various forest stressors and assesses
recent impact, through 1991, on the forests within the 20 States
that comprise the Northeastern Area of the USDA Forest Service.
Through these annual reports, we hope to be able to
identify factors that may be affecting forest condition within
this area.

ABSTRACT: Results from a South-wide timber supply projection
to the year 2020 are examined and compared against national projections.
Using the latest FIA survey unit data for the South (excluding
Kentucky and public ownerships) individual state inventories were
updated to 1994 as a common starting point for the projection.
Only private ownerships were considered in the model. Softwood
prices are projected to increase seven times and hardwood prices
over two and a half times over the projection period. The largest
projected price increases for softwoods occur during the decade
2010 to2020. Inventory of softwoods is projected to decrease by
30 percent relative to the starting year, and hardwoods to increase
only slightly by 2 percent South-wide softwoods growth to removal
ratio is expected to decline from 0.94 to 0.71, and from 1.36
to 0.87 for hardwoods. Price projections are sensitive to growth
per acre assumptions. The results in this paper are conservative
in that they assume constant productivity levels in planted pine
forest types.

ABSTRACT: The Colville Study was developed in 1994 to identify
and evaluate a series of management options for achieving ecosystem
objectives in dense stands of small-diameter trees while also
producing wood products. The Colville National Forest selected
the Rocky II Timber Sale as an example of this type of stand that
needed management to achieve the following goals: (1) create late
successional forest structure, (2) decrease forest health risk
from fire, insects, and disease, (3) improve wildlife habitat
by providing large green trees and snags, and (4) improve stand
aesthetics by decreasing stand density.
The Colville Study was divided into four technical focus areas:
Silviculture and Ecology, Forest Operations, Timber Conversion,
and Economics. Results of each technical focus area indicate that
(1) vegetative management activities are necessary to achieve
the ecosystem goals, (2) there are alternative harvesting systems
for removing the timber in an ecologically sound manner but costs
need to be considered, (3) both species and material size are
important in the recovery of wood products, and (4) financial
analysis needs to incorporate all of these factors and many more
to effectively evaluate the relative merchantability of different
types of treatments.

MARKETS / ECONOMICS
Araman, P.A. 1987. Eastern United States hardwood sawtimber
resources and export potential. In: Proceedings of SOFEW/MWFE
Joint Annual Meeting. Asheville, N.C.
ABSTRACT: To look at the export potential of the Eastern hardwood
sawtimber resources, including the Southern and Northern regions,
hardwood resource data were compiled from USDA Forest Service
state resource evaluation reports on a set of select export species.
The species are the select oaks, yellow birch, hard maple, black
walnut, black cherry, and the ashes. These species were chosen
on the basis of their importance to the export market. Resource
data are presented on standing hardwood sawtimber (inventory,
growth, and removals) of the select export species, and on all
hardwood sawtimber. Estimates of standing sawtimber for 1985 are
presented along with projections for 1990,1995, and 2000 for the
Eastern United States and the Northern and Southern regions.
The relative export potential of the hardwood resources by state
was determined by the Preferred Available eXport species (PAX)
ranking system. In this system, we first order the first 25 states
by total quantity of select export species. Next, we evaluate
these 25 states with an Export Index formula. The formula uses
data on the quantity and quality of the standing sawtimber in
the select export species. A premium is placed on select oak sawtimber
because about two-thirds of the hardwood product exports are oak.
A premium also is placed on grade 1 log sawtimber material because
many of these logs are exportable; and if processed in the United
States, they contain sizeable amounts of exportable high-grade
lumber or veneer. The PAX rankings are presented for the top 25

ABSTRACT: Management-cost data were gathered for various reproduction
cutting methods as part of the ecosystem management research in
the Ouachita Mountains. Costs were gathered on both traditional
and nontraditional reproduction cutting strategies in an attempt
to determine the cost-effectiveness of each management strategy
and to estimate the resource requirements for wide-scale implementation
of each method. Preliminary results indicate that sale preparation
costs are higher for low volume-per-acre cutting methods.

ABSTRACT: Many markets for hardwood lumber have experienced
growth in recent years. Eastern and Central hardwood lumber production
reached an estimated 11.2 billion board feet in 1988, a twenty
year high. Wood furniture, flooring, and exports have also experienced
growth in the last ten years. During the same period, annual growth
on eastern hardwood forests has exceeded annual removals. However,
species and grade compositions do not match demand. These differences
can affect timber harvest and the availability of raw material.
Keywords: Hardwood, exports, sawtimber quality, log grade,

Economic impacts of the forestry and forest products industries
on the Tennessee economy. Tennessee Forest Products Center.
University of Tennessee, Knoxville, TN. Report no. 5.

ABSTRACT: An impact analysis to examine the relative importance
of the forestry related sectors to the overall Tennessee economy,
utilizing the IMPLAN database and model, was conducted. The 1994
data used for this study were the most recent available. The Tennessee
input-output economic model results indicated the Tennessee forest
products industry directly employed 69,811 people and paid about
$2.3 billion in wages in 1994. The industry generated directly
an industry output of about $9.1 billion, and value-added totaled
over $3.9 billion. When the forestry sector of the Tennessee economy
produces products or services to meet demand, the overall State
economy is affected in three ways: directly, indirectly and with
induced effects. The total effect on the state economy is the
sum of these three separate effects. Therefore, in 1994, relative
to other Tennessee industries, the total effect of the forest
products sector was 162,886 jobs, over $3.5 billion in wages and
salaries, $15.5 billion of industrial output, and over $ 7.5 billion
of value-added.
Keywords: value-added, Tennessee forest products industries,

ABSTRACT: Six stands were harvested by either clearcut, shelterwood,
or single-tree selection methods. Harvest productivity was evaluated
in 2 consecutive years (1991 and 1992) for each harvesting method.
The single-tree selection harvests consisted of thinnings in even-aged
stands as an initial basal area reduction cut required to convert
the stand to uneven-aged structure. Harvest intensity (percentage
of basal area removed) ranged from 31 to 100.
The same contractor used two skidders (one grapple, one choker)
and production chain saws to harvest all six tracts. Harvested
sites were similar in slope, average diameter at breast height
(d.b.h.)and preharvest number of stems by d.b.h.
In 1991, total felling time (including walk, acquire, fell, and
limb-top times) was inversely related to harvesting intensity.
In 1992, total felling time averaged highest under the single-tree
selection method and lowest under the shelterwood method. When
these averages were adjusted for differences in stand characteristics,
the inverse relationship between total time and percentage of
basal area removed at harvest (harvesting intensity) was present
for both years.
In both years, total cycle time (including travel-empty, bunch-building,
travel-loaded, and deck times) was higher, and volume per cycle
was lower for the cable skidders than for the grapple skidders.
After adjusting for differences between stands, total cycle time
was inversely related to harvest intensity.
Factors affecting total felling time (in decreasing order of importance)
were d.b.h. of harvested stems, distance between trees, and harvest
intensity. Factors affecting total cycle time for skidding (in
decreasing order of importance) were travel distance, skidders
type, number of stems per cycle, harvest intensity, and volume
per cycle.
The total percentage of stand area trafficked was lowest for the
single-tree stands. The single-tree selection method (in 1992)
had the largest and only significant increase in bulk density
in the skid trails. Residual tree damage (trees/acre) was greater
for the single-tree selection method than the shelterwood method.
Keywords: single-tree harvest, residual tree, shelterwood,
clearcut, skidders, damage, cost.

ABSTRACT: Sixteen stands were Harvested at intensities (proportion
of basal area removed) ranging from 0.27 to 1.00. Logging contractors
used chain saws and rubber tired skidders. Harvested sites were
similar in slope and tree size.
Harvest time per tree was inversely related to harvest intensity
and directly related to tree size. Factors affecting total skidding
time were skidding distance, skidders type, harvest intensity,
load volume and number of stems.
Harvesting profitability per 100 cubic feet was near zero when
removing trees averaging less than eight inches DBH. Harvest intensity
had the greatest influence on profitability in small diameter
timber. Harvest profitability was greatest when removing large
trees at high levels of harvesting intensity.

and Natural Resources. 8:111-113.
ABSTRACT: Forestry activities, such as timber production and
processing, are important economic activities in many rural communities.
Yet the research on the relationship between forest dependence
and community economic well-being is inconclusive. This article
examines the relationship between forest dependence and county
per capita income and poverty in rural Georgia. Forest dependence
is conceptualized according to Averitt's theory of the dual economy.
Core dependence, in other words dependence on well-capitalized
pulp and paper firms, is expected to affect county-level economic
well-being differently than dependence on periphery forest industry
or high timberland concentrations. Regression analyses show that
core forest industries are positively related to county per capita
income, while periphery industries have no significant effect
and timberland concentration is negatively related to per capita
income and positively related to the poverty rate.
Keywords: core, dual economy, periphery, rural development,
uneven development.

ABSTRACT: A total of 1,896 firms processed Missouri-grown and
harvested timber in 1983. They employed 20,927 persons and paid
wages of $253 million. They purchased wood raw materials that
cost $355 million and other goods and services for $406 million.
The products they sold were valued at $1,343 million and the total
value added by processing was $582 million.
The paper products sector, which uses pulp and paper produced
in other states, included 143 firms that employed 12,300 people
and paid wages of $230 million in 1982. Paper processors bought
goods and services valued at $869 million and their products sold
for $1,551 million. Value added was $680 million.
If a portion of other related activities, such as construction,
transportation, and marketing, are considered in terms of value
added, timber-based activity in Missouri in 1983 is valued at
an estimated $1.8 billion.
In total in 1983, 2,000 firms with 33,000 employees who earned
$483 million in wages produced goods valued at almost $3 billion.

for eastern hardwoods resulting from harvest restrictions in the

ABSTRACT: Efforts to conserve the habitat of the northern spotted
owl in the Pacific Northwest have placed softwood timber supplies
under a great deal of pressure and driven up the price of softwood
lumber. Hardwoods could meet some of the demand for products that
have previously been manufactured from softwood species. Hardwood
structural lumber may soon become an economically feasible alternative
to softwood lumber. Oriented strand board is likely to gain a
greater share of the structural panel market. Opportunities also
exist for treated hardwood lumber and treated hardwood shakes
and shingles. Hard-woods might also be used to make increasing
proportions of many secondary wood products such as moulding,
millwork, and flooring.

Forestry community or granfalloon. Journal of Forestry.
92(9): 6-10.
ABSTRACT: Are forest owners members of the forestry community,
or is the community a granfalloon? Insofar as they control so
much of the nation's forest resources, forest owners certainly
"belong" to the forestry community. However, in their
forestry knowledge and opinions they mirror the general public.
The lines between forestry "advocates" and "adversaries"
are far less distinct than may be commonly assumed and apparently
do not depend on forest ownership.
Our Tennessee Valley region results are consistent with those
found in two previous Alabama surveys (Bliss 1993a, 1993 b) and
with results of recent research in Pennsylvania (Luloff et al.
1993). Perceived environmental effects are the litmus test of
public approval in forestry issues. Environmental concerns temper
views toward forestry practices, private property rights, and
forest-based economic development. Most forest owners and non-owners
desire a balance between property rights and environmental regulations,
which ensures environmental protection.
When and where forestry is perceived to be environmentally friendly,
it will enjoy public support. Opposition to individual forest
practices is due, in part, to lack of knowledge about forests
and their management. The public knows little about forestry,
and it doesn't like what it doesn't know. Continuing to concentrate
on education efforts on forest owners alone will do little to
improve the acceptance of forest management by the American public.

In the mainstream: environmental attitudes of mid-south forest
owners. Southern Journal of Applied Forestry. 21(1):37-43.
ABSTRACT: A 1992 telephone survey of households in seven mid-South
states provided data for comparing the opinions of NIPF owners
with those of the general public. Topics explored included traditional
forest management practices, governmental regulation of tree cutting
to protect environmental values, and trade-offs between environmental
protection, private property rights, and economic development.
In each of these areas the views of NIPF owners were found not
to differ significantly from those of the general public. A wide
spread desire for environmental protection tempers views toward
forest practices, forest-based economic development, and private
property rights. The relationships between NIPF owners' demographic
characteristics, ownership activities, and opinions were explored.
Study results challenged common assumptions about NIPF owners,
questioned the effectiveness of existing forestry education efforts,
and argue for a stronger, more explicitly environmental orientation
in all forestry activities.

management on multiple NIPF ownerships. Journal of Forestry.

ABSTRACT: Both professional foresters and the general public
are increasing interested in an ecosystem-based approach to forest
management. This emerging interest raises the question of how
such an approach might apply in a landscape that is dominated
by numerous nonindustrial private forest (NIPF)ownerships. This
article reports on the results of a pilot study of a voluntary
incentive-based program in one town in western Massachusetts.
The chief criterion of success in the short term will be the number
of neighborhoods landowners, acres and natural resource consultants
involved; and whether a change in awareness or understanding of
options has occurred. In the nine months since the programs inception,
two Stewardship Neighborhoods have begun that involve eight landowner
families, 457 contiguous acres, and three private consultants.
The cost sharing incentive to develop voluntary opportunities
for collaboration imposes no obligations, nor does it remove any
landowner rights. We believe this approach of combining education,
information, and incentives should be investigated as we attempt
to encourage management of forested ecosystems in a landscape
dominated by NIPF ownerships.

Stewardship incentives in forestry: Participation factors in Tennessee.
Southern Journal of Applied Forestry. 21(1): 5-10.
ABSTRACT: The likely effect of cost-share incentives on participation
in Tennessee's Forest Stewardship Program was estimated and contributing
factors were identified. Surveys were mailed to 4,000 nonindustrial
private forest (NIPF) landowners, and a logit model was developed
to examine economic, physical, and behavior factors which affect
the landowner participation decision. Data collected indicates
the majority of landowners are concerned with water quality and
wildlife habitat in addition to timber enhancements. Model results
indicate that attitudes, experience, and knowledge of forestry
programs may outweigh monetary incentives (50, 65, and 75% cost
share) in the participation decision.

ABSTRACT: Results from a study of the within-stand visual effects
of alternative reproduction cutting methods on 20 experimental
plots in the Ouachita National Forest are presented. Treatments
varied in their level of hardwood retention from complete suppression
of hardwoods to retention of 30 ft2/acre of basal area. Using
color transparency film, plots were photo-sampled two growing
seasons after treatments were imposed. The color slides were rated
for their scenic beauty by students at Texas A&M University.
Results showed that perceived scenic beauty increased with the
level of hardwood retention and that summer, fall, and spring
views were preferred over those taken during the winter. Ridgetop
plots on north-facing slopes were rated as significantly more
scenic thin plots on gentle-slope north-facing positions.

ABSTRACT: Survey of the Georgia public. The results show that
the general public has a fairly positive image of people within
and associated with the forest products industry. A majority also
have a knowledge of and give support for more forest management
practices than we had anticipated. Although this study points
to some possible areas that should be addressed by those in forest
industry, it appears that those employed in the forestry sector
have begun to realize that informing and involving the public
is necessary not only for good public relations and improved community
cooperation, but also for the long term maintenance of their ability
to mange.

ABSTRACT: The majority of forest visitors interviewed between
June through October 1991 and April through October 1992 preferred
forest scenery that was "undisturbed", contained a "variety
of natural features", or was associated with "natural"
or "beauty" descriptions. Few respondents preferred
"younger tree species with open areas." Results suggest
that undisturbed conditions are important along with vegetation
management to support a variety of natural features. Slight differences
are noted when examining preferences by respondents' sex, age
class, education level, principal recreation activity, month visited,
and sites where interviewed. The order of questions appeared to
affect the respondents' forest scenery descriptions. Interviews
were conducted as part of an onsite survey involving a larger
recreation-user study (CUSTOMER survey) for sites among four USDA
Forest Service Ouachita National Forest ranger districts. Recommendations
are made for using CUSTOMER survey data in future forest scenery
preference research.

Respondents' unique views, values, and stakes are heard, and emergent
similarities and differences among them are analyzed in a qualitative
study. While a majority of 17 participants criticized the Ouachita
National Forest's recent transition to uneven-aged management
other study participants lauded the Ouachita National Forest's
move to uneven-aged management. In the following pages, the variety
of ways in which the woods workers perceived and valued the use
and management of timber is reported. Studying perceptions and
values regarding timber management aids us in generating a better

ABSTRACT: An analysis of summer visual attributes and an overview
of ongoing scenic quality research within selected shortleaf pine
(Pinus echinata Mill.)
-hardwood stands in the Ouachita and Ozark National forests are
presented. Within-stand visual attributes were reported prior
to even-aged stand-level (Phase 11) treatment for twelve 40-acre
stands in the north, east, and south regions and for plot-level
(pre-Phase 1) visual attributes for twenty 0.5-acre plots examined
two growing seasons after disturbance. No differences in visual
attributes before treatment were apparent between 0.0 to 2.8 feet
and 2.9 to 5.5 feet aboveground. From the stand-level study, there
were no significant differences among regions but there were significant
differences among stands and sample points. The plot-level study,
a randomized complete block design with four blocks or landform
positions and uneven-aged treatments, revealed differences by
distance zone above ground for disturbed plots. Greater foliage
and twig screening and reduced visual penetration in lower zone
views were associated with increased overstory removal. Visual
penetration was lower and foliage and twig screening was higher
in low elevation landform positions compared with high elevation
landform positions. Insight from both studies suggests that a
significant difference between viewing zones in summer may be
suitable as an index of recent stand disturbance.

ABSTRACT: Following a review of the influences on how we make
decisions of land use, the author suggest that we might want to
make use of the evolving concept of social responsibility (within
a framework of an emphasis on basic human rights) and that we
might want to use it in a way that begins to bring elements of
a new social value system right into the heart of contemporary
discussion of economic policy and land use policy. The concept
might allow us to move away from the emphasis on individual rights
toward an emphasis on the common good without having to invent
a whole new ethical vocabulary for the American Public.

Williams, R.A. and R.A. Kluender. 1997. Perspective of Arkansas'
Non-industrial private forest land owners concerning their forested
property. (Unpublished)
ABSTRACT: Today's non-industrial private forest (WF) owners
must deal with a variety of problems and issues that were uncommon
just a few years ago. Management issues, such as best management
practices and private property rights; environmental issues, such
as endangered species and land stewardship; and economic issues,
such as capital gains tax, forestry incentive programs, and property
tax must be considered if the overall operation is to be successful
and survive.
To find out what Arkansas' NIPF owners think about these and other
issues, personnel from the Arkansas Forest Resources Center and
the University of Arkansas at Monticello and Fayetteville conducted
a survey. The study was separated into a series of focus groups
and a mail survey. The focus groups were made up of non-industrial
private forest owners from four counties in Arkansas. The mail
survey included the same four counties and eight additional counties.
All of the counties used in the study were randomly selected and
represented all parts of the state.
The focus group participants identified several major areas of
concern to NIPF owners. These concerns included timber theft,
trash dumping and improper payments for timber sold from their
lands. Regional differences were observed in the use and knowledge
regarding management practices, incentive programs and environmental
concerns.
The survey results echoed the same theme of property rights as
all participants believed they had a right to use their land in
any fashion. However, most of the participants were not aware
of the Endangered Species Act or Clean Water Act as it applies
to private landowners. Finally, most participants considered themselves
middle-ground environmentalists. They defined the term to mean
land stewards who have concerns for the environment but are able
to use the natural resources present on their lands. The information
obtained during this study provide many insights into the behavior
and attitudes of NIPF owners throughout Arkansas. The study has
set in motion a series of landowner workshops that have been attended
by over 500 participants.

18-20, 1996. Washington, D.C. USA. 230-237.
ABSTRACT: The focus group sessions provided good insight into
the NIPF owners of Arkansas. Regional differences were identified
as to land use preference and use of incentive programs. The Delta
and Southwest regions were interested in growing and selling trees.
They also used incentive programs to help them establish and grow
their trees. The Ouachita and Ozark regions preferred grazing
and recreation uses on their forest-lands. All participants felt
that they were land stewards who used their land resources tempered
with environmental sensitivity. Furthermore, they do not want
land use regulations restricting activities on their lands. Some
major concerns listed by all participants included trespassing,
trash dumping, and timber theft. This NIPF owner study might be
useful for developing landowner educational and extension programs
and future research efforts that could better address the concerns
and interests of Arkansas NIPF owners.

ABSTRACT: The results reported here are based upon a mail survey
that was sent to 2,400 forest landowners in a random sample of
12 Arkansas counties. Using standard procedures for mailed surveys,
using a questionnaire that was designed from the previous one
and from input received at four focus groups held in the four
regions of Arkansas. Nearly 870 usable questionnaires were returned.
Non-industrial private forest landowners held a high regard for
being good stewards of the land, liked the rural environment and
wanted to provide wildlife habitat. About half of the respondents
have sold trees in the past and fewer than half plan to sell sometime
in the future. The Coastal Plain region had the most owners who
sell trees and manage their forest lands while the Ozark region
had more landowners who owned forest lands for reasons other than
income from their trees.

ABSTRACT: The Gallup Organization (Gallup) has been commissioned
by the Southwest Missouri Resource Conservation and Development,
Inc. (Southwest Missouri RCD) to determine attitudes among landowners
in terms of the primary reasons for owning their land, services
used for their land, as well as what differences if any exist
among landowners in lake counties and non-lake counties. Following
are some interesting highlights of the study.
· Over four out of five (82 %) landowners viewed "beauty
or nature appreciation" as being a somewhat or very important
reason to own their wooded land.
· The primary activities respondents have performed on
their land within the past ten years were planting trees, improving
wildlife habitat, and cutting timber.
· More than one-third (37 %) of landowners intend to plant
trees on their land, and almost two-thirds (65 %) of landowners
stated that if provided with trees, they would plant them.
· Surprisingly over three out of five (61 %) landowners
are completely unaware of any type of cost-share assistance. However,
if cost-share assistance were available, nearly one-third of respondents
would use it.
· Respondents tended to not seek out management advice
or use any services. However, landowners who did use services
ranked wildlife management assistance and forest
management practices as their most preferred services.
· Approximately one out of ten (11 %) landowners would
be willing to pay for forest management services.

ABSTRACT: This report, part of Missouri's State Comprehensive
Outdoor Recreation Plan (SCORP) for 1996-2001, reviews and analyzes
information relating to state and nationwide outdoor recreation
trends, and projects recreation needs for the State of Missouri
through the year 2001.
The Statewide Comprehensive Outdoor Recreation Plan (SCORP) is
a federal requirement which historically has enabled states to
receive and administer federal Land and Water Conservation Funds
(LWCF). In addition to this specific purpose, Missouri has used
the SCORP as a planning tool for state outdoor recreation programs.
In October, 1995, the Missouri Department of Natural Resources'
Division of State parks, commissioned a consultant team to conduct
research for the 1996-2001 Statewide Comprehensive Outdoor Recreation
Plan (SCORP) and report the results. Identified are 11 primary
needs, which range from the expansion of facilities to the education
of outdoor recreation users in land ethics.

Appalachian hardwood stand after clearcutting. Southern Journal
of Applied Forestry. 10(3): 168-172.
ABSTRACT: A mixed hardwood stand composed of 53% oak (Quercus
spp.), 33% yellow-poplar (Liriodendron tulipifera L.), and 14%
other species, was clearcut in 1963. Twenty years later a developing,
even-aged stand of predominantly sprout origin is dominated by
yellow-poplar, black locust (Robinia pseudoacacia L.), red maple
(Acer rubrum L.), and sweet birch (Betula lenta L.). The oaks
are a minor and decreasing component.
This and other studies suggest that clearcuts on good sites in
the Southern Appalachians will be dominated by aggressive intolerant
species-mainly yellow-poplar. If a larger oak component is desired,
measures to ensure strong advance reproduction and lessen competition
from prolific sprouters such as red maple will be necessary.

Beck, D.E. 1991. The shelterwood method. A research perspective.
In: Proceedings of the Genetics/Silviculture workshop. Wenatchee,
Washington. 252-258.
ABSTRACT: The fundamental purpose of the shelterwood method
is to get a new crop of trees established before the old one is
completely removed. Stands created by shelterwood cutting are
usually even-aged, but there are variants in which the stands
have two age classes or have trees ranging over several decades
in age. The number and intensity of cuts, interval between cuts
, and treatment of the understory and forest floor can be varied
to achieve a wide range of environmental effects in both space
and time. It can also be used to create a wide range in visual
effects.
The shelterwood is an extremely flexible method that can be used
to solve a wide range of regeneration problems. Practically all
the major species of this country are amenable to its use and
many demand it. In fact, it may be at least a partial answer for
some of the failures now being experienced when planting following
clearcutting. Given the option of maintaining two-aged stands,
it has the potential to incorporate esthetic, wildlife, and other
management needs into a regeneration method for species that are
intolerant or intermediate in tolerance. As should be very clear

Bey, C.F. 1964. Advanced oak reproduction grows fast after
clearcutting. Journal of Forestry. 62(5): 339-340.
ABSTRACT: In the spring of 1936, two 1-acre oak-hickory plots
were clearcut on the Shawnee National Forest in southern Illinois.
Twenty-seven years later, the study plots were fully stocked with
oaks, hickory, black walnut, and yellow-poplar trees, sapling
size and larger. The trees grew rapidly and were straight stemmed.
Most of the oak "seedlings" that developed after the
cutting were sprouts from older root systems. Where desirable
advance oak reproduction is present, clearcutting will result
in a high percentage of rapid-growing, straight-stemmed oaks.

size for multiple-use silviculture - a discussion paper. Forest
Ecology and Management. 48: 249-264.
ABSTRACT: An argument is presented that the essential difference
between even-aged and uneven-aged silviculture ties in the proportion
of the patch that is influenced by edge effect. These edge effects
may extend well beyond the normally accepted boundary between
even-aged and uneven-aged stands. Examples are presented to show
that there is not one static edge effect but many dynamic edge
effects and that the differences between even-aged and uneven-aged
stands are represented by a continuum rather than there being
a distinct division between them. In the continuing debate on
appropriate forest management practices, the differences between
even-aged and uneven-aged silviculture have been oversimplified
and are often represented in their extremes. In this paper it
is argued that research to quantify the magnitude and the extent
of these edge effects is necessary to provide the essential data
to design patch sizes to meet specific multiple-use management
objectives. The integration of these data would provide the basis
for objective trade-offs between various forest values and for
the objective evaluation of the long-term impact of different
silvicultural practices.

in Southern Appalachian Hardwoods. Southern Journal of Applied

ABSTRACT: A woodland tract of southern Appalachian cove hardwoods
and mixed oak has been managed under the selection system of silviculture
since 1946. Simply cutting in all commercial diameter classes
(i.e., 6.0 inches and larger), as was the practice during the
first 24 years, failed to develop enough desirable saplings and
poles to maintain the system. After 1970, herbicide treatment
of undesirable, tolerant understory species in openings created
by, removal of large trees or groups of trees has improved the
status of desirable saplings. Although long-term costs of management
and yields are uncertain, the study suggests that creation of
larger openings and treatment of undesirable understory species
offers at least a chance for success with the selection system
in southern Appalachian hardwoods.

following clearcutting of oak during a seed year. Journal
of Forestry. 58: 711-715.
ABSTRACT: Red and White Oaks, (Quercus rubra L. and Q. alba
L.), when growing on good sites, produce high quality hardwood
timber. Because of the value of high quality oak, forest managers
are interested in maintaining these species on sites capable of
producing quality trees. However, on the better hardwood sites,
oak reproduction is usually out-numbered by lighter-seeded species
such as American elm (Ulmus americana L.), Sugar and red maples
(Acer saccharum Marsh. and A. rubrum L.) and white ash (Fraxintus
americana L.), as well as by less desirable species such as sassafras
(Sassafras albidium (Nutt.) Nees), hawthorn (Crataegus spp.),
and witchhazel (Hamamelis virginiana L.).
A study was made of reproduction following clearcutting of an
excellent 45-acre oak stand in 1950 in southern Michigan. The
stand composition before cutting was primarily red and white oak,
with lesser volumes of sugar maple, yellow-poplar, elm, white
ash, and red maple. The reproduction was examined 2, 3, 5, and
7 years after logging.
Clearcutting of this oak stand has been followed by adequate reproduction
to form a fully stocked new forest stand. However, the composition
of the new stand bears little resemblance to that of the previous
stand. The important species forming the new stand are white ash,
sugar maple, American elm, black cherry and red maple, in that
order. The small number of oaks now present occur in clumps of
sprout origin, and their distribution in the stand is poor.
The clearcutting method has not resulted in obtaining adequate
oak reproduction in the new stand on this area..

ABSTRACT: In the current wave of public concern about clearcutting,
the selection method of uneven-aged silviculture has been consistently
advocated as an alternative. Its advantages over clearcutting
include improved cash flow, production of high-quality sawtimber
and better aesthetics. As a result, many foresters with little
or no education or experience in uneven-aged silviculture have
been eagerly imposing the selection method in forest stands across
the nation. However, in many cases the stands are really being
managed by uninformed, mistaken or wishful intent rather than
by strict attention to acknowledged uneven-aged standards. This
paper presents guidelines for the application of uneven-aged silviculture.
It provides a good comparison between uneven-aged and even-aged
silviculture. It presents concerns that forest are being mismanaged
as uneven-aged when in reality they are even-aged and inevitably
it is the sustainability of the forest which will then suffer.
This is a hidden dilemma, because the failure of selective cutting
may not become apparent for several decades. Differences in interpretation
of these guidelines among foresters may lead to debate about the
importance of achieving these standards - which is encouraged.
If systems that deviate--from these guidelines are proposed as
uneven-aged, the proposers might do well to examine whether the
deviations are not resulting from an effort to retain some semblance
of even-agedness for convenience, operability or other non-silvicultural
constraints. The ultimate failure of a poorly-grounded, uneven-aged
system may not occur for several decades - by which time the future
potential of the stand is irretrievably sacrificed. Foresters
attempting to practice uneven-aged silviculture can check their
prescriptions against these guidelines, and might want to consider
adjusting their operations to ensure that the guidelines are achieved.

design and harvest intensity on forest damage caused by selective
logging: empirical results and a simulation model from the Bosqu
Chimanes, Bolivia. Forest Ecology and Management. 59: 1-14.
ABSTRACT: The effects of road design and harvest intensity
on forest damage caused by selective logging: empirical results
and a simulation model from the Bosque Chi-manes, Bolivia. Selective
harvesting in tropical forests has been shown to cause considerable
damage to residual trees in stands that have relatively high densities
of commercial trees. To complement existing studies, we measured
forest damage caused by the selective harvesting of mahogany (Swietenia
macrophylla),a very low density species in the Bosque Chimanes,
Bolivia. Secondary damage along main roads and skid trails accounted
for most of the damage measured in the study site. Total damage
was low (4.39% of the study area), but results from our simulation
model suggested that damage could be decreased by up to 25% by
requiring main roads and skid trails to be linear.
We used our simulation model to investigate the relationship between
harvest intensity and forest damage. At low harvest intensities,
most forest damage occurs from the construction of main roads.
As harvest intensity increases, secondary damage from skid trails
and tree felling comes to dominate forest damage. Overall, less
damage will result to the forest for a given harvest volume if
the harvest area is reduced and harvest intensity increased. Additional
benefits to increasing harvest intensity are that re-entry into
the logged site can be delayed, allowing the forest more time
to recover, and regeneration of light-demanding species such as
mahogany can be enhanced. The main impediment to increasing the
harvest intensity in selective harvesting operations in Latin
America is the lack of international markets for lesser known
species, although there is some local and national demand.

of whole-tree harvesting under different silvicultural methods.
Northern Logger. 29(11): 60-61 and 82-84.
Whole-tree harvesting is being used more widely to obtain wood
fiber from our forests. In whole-tree harvesting the trees are
felled with a chain saw or by mobile felling machines and hauled
in-tact to a landing. At the landing saw logs can be removed and
the remainder of the tree chipped and blown into trailer vans.
Chips so derived are suitable for electric generation, for heating,
or for manufactured products. Quality of chips for more exacting
product requirements can be improved by removing bark, limbs and
leaves before chipping.
Whole-tree harvesting involves removal of most of the above ground
biomass from a forest site. This method of intensive forest harvesting
raises concern about long-term soil nutrient status, soil compaction,
soil erosion and water quality, and the long-term production potential
of the site.
This papers primary emphasis is on the impacts to regeneration
and the residual stand.

Journal of Applied Forestry. 4(2): 97-101.
ABSTRACT: Oaks, one of the most abundant species groups in
the eastern United States, are difficult to regenerate in the
time, place, and abundance desired. Regeneration is hampered by
insect damage to acorns, consumption of acorns by animals, and
competition by other more shade tolerant vegetation. With animal
populations managed at tolerable levels, adequate stocking of
oak seedlings can be accomplished with most conventional regeneration
methods. With the clearcut and seed-tree method the harvest must
be timed with a good seed year. Oak stump sprouts will also contribute
to the regeneration. The one-cut shelterwood method can work if
there is adequate advanced regeneration. Two- or three-cut shelterwood
should work well with about 60% crown cover in high shade or 60%
stocking after the first cut. The group selection method should
also be effective if regeneration is released from above once
established. The key with all these methods is to control competing
vegetation, keeping the oaks dominant and free to grow; oaks like
plenty of light. Once oak is well established and about 5 ft high,
any overwood should be carefully removed to minimize seedling
damage. If desired for esthetic, wildlife, or economic purposes,
a light canopy cover can be retained as a reserve shelterwood.
Management of oak requires intensive silviculture; casual treatment
of stands at long intervals will seldom result in good regeneration.

for the small forest owner. New Haven: Yale University. Yale
University : School of Forestry. Bulletin No. 35.
ABSTRACT: A large part of the forest land in Connecticut is
held in connection with farms or country homes. Such properties
usually contain from a few to two or three hundred acres of woodland.
While there are in the State solid blocks of forest, often covering
several thousand acres, such extensive holdings are not considered
in this publication. Large blocks of forest ultimately should
go to the State to be incorporated within its forest system, or
to the occasional landowner who desires a relatively large forest
property.
The problem of the small forest landowner is here discussed. His
wooded area is an essential part of the holding, either because
it is interspersed among the arable fields or because it is needed
to round out an otherwise irregular boundary or to give the desired
setting for the homestead. In fact, unless he confines himself
to house lots, the owner of rural property will find possession
of forest land well-nigh unescapable. This situation is a distinct
advantage of rural life, although it creates responsibility for
intelligent use of forest areas. In the past, to the detriment
of the owner's best interests, the forest has been too often totally
neglected or improperly handled.
This bulletin, from 1932, makes a clear case for the small woodland
owner to apply the selection system of timber harvest rather than
clearcutting. This paper should make clear that the debate surrounding
the appropriateness of silvicultural systems is not new, and in
fact continues to this day.
Keywords: selection cutting, clearcutting, small woodland owner,

ABSTRACT: The silviculture of upland central hardwoods has
largely followed an ecological model based on the manipulation
of existing natural vegetation and a reliance on natural regeneration,
rather than on an agronomic model based on intensive culture and
the introduction of new genotypes. On publicly owned and industrial
lands, growing high quality sawtimber has been emphasized. Exploitive
high grading has characterized timber harvesting on nonindustrial
privately-owned forests. On well-managed forests, intermediate
cuttings in even-aged stands have been widely used to improve
stand quality and to accelerate growth of the residual stand.
Enduring silvicultural tools include polymorphic site index curves,
and stocking charts and equations. Abandoned or declining practices
on public lands include clearcutting and autonomous silvicultural
decisions by forest managers. Evolving or reemerging practices
include uneven-aged silviculture using single-tree and group selection
methods, shelterwood methods that incorporate artificial regeneration,
and irregular shelterwood methods. Evolving silvicultural tools
include predictive regeneration models, acorn production models,
and prescriptions for prescribed burning for oak regeneration.

ABSTRACT: There are three juvenile growth forms of oak that
silviculturists commonly term "reproduction": (1) seedlings,
(2) seedling sprouts, and (3) stump sprouts. A seedling is a form
that has not experienced shoot dieback. Seedlings become seedling
sprouts by surviving shoot dieback and resprouting one or more
times. Seedling sprouts may persist and accumulate for decades
in xeric forests and sometimes in mesic and hydric forests that
are recurrently burned, grazed, or otherwise disturbed. Stump
sprouts arise from the stumps of cut overstory trees after a thinning
or final harvest and sometimes from the bases of fire-killed trees.
When present before a silvicultural event such as clearcutting
or shelterwood removal, all three growth forms are collectively
called advance reproduction. The number, size, and spatial distribution
of oak advance reproduction and the capacity of the parent stand
(overstory) to produce oak stump sprouts can be used to assess
a stand's oak regeneration potential, i.e., its capacity to occupy
and dominate growing space at a specified time in the new stand.
Because the population dynamics of oak reproduction vary greatly
among species and different kinds of oak forests, this variation
should be recognized in assessing stand regeneration potential.

rgenerations and overstory density in the Missouri Ozarks. Canadian
Journal of Forestry Research. 27: 1-7.
ABSTRACT: Reducing overstory density is a commonly recommended
method of increasing the regeneration potential of oak (Quercus)
forests. However, recommendations seldom specify the probable
increase in density or the size of reproduction associated with
a given residual overstory density. This paper presents logistic
regression models that describe this relation for a forest in
the Ozark Highlands of Missouri that has been managed for 40 years
by the single-tree selection system. In general, density of oak
reproduction of a given size increases with decreasing residual
stand basal area. However, the corresponding increase in the reproduction
density at all levels of overstory density indicates low predictability
of individual stands. The models nevertheless describe the average
trend in the highly stochastic regeneration process. They also
suggest that stand densities must be kept low (e.g., basal areas
<14 m2 ha-1) to sustain the requisite recruitment of reproduction
into the overstory under the single-tree selection method.

ABSTRACT: Successful application of the single-tree selection
system in Ozark oak forests depends on sustaining adequate recruitment
of reproduction into the overstory. In turn, this requires maintaining
stand density at ecologically appropriate levels. The ecological
requirements for oak recruitment are discussed and guiding curves
are presented that meet those requirements.

in the Southern Appalachians: a research approach. Proceedings:
Second Biennial Southern Silvicultural Research Conference. Atlanta,
Georgia. November 4-5. 144-150 pp.
ABSTRACT: Red oak (Quercus rubra L.) stems in a favorable competitive
position are usually absent from recently created even-aged stands,
even where red oak was a prominent component of the previous stand.
Past research indicates that lack of adequate advance reproduction
is the problem on productive sites. A quantitative approach to
develop predictive models of regeneration development is outlined.
The objectives of this research are to provide:
(1) a method of predicting performance of advance reproduction
after harvest, and (2) the silvicultural practices which will
enhance the development of advance reproduction. Using this information,
the manager would be able to maintain red oak as a component in
these stands.

in an upland hardwood stand following a Shelterwood harvest.
Northern Journal of Applied Forestry. 5(1): 46-49.
ABSTRACT: In 1958, 85 permanent mil-acre plots were established
in a 3.5-ac shelterwood harvest area to monitor regeneration over
time. Individual seedlings were numbered with metal tags in this
predominantly red oak stand in east-central Wisconsin. Findings,
after 26 growing seasons, indicate a low proportion of red oak
in the present stand (7.8% of the basal area, 3.6% of the stems).
The predominant species is now eastern hophornbeam (iron-wood),
although other species such as white ash and basswood are common.
All of the present red oak became established after the initial
regeneration counts. Height growth and survival rates were significantly
higher for those stems taller than the mean seedling height in
1959.

ABSTRACT: Visual impacts of forest operations are of increasing
concern to forest managers. Tools are available for evaluating,
and potentially avoiding, problems in visual quality resulting
from poorly designed harvest unit boundaries. One of these visualization
tools is applied in comparing various harvest unit shape alternatives
in an upland hardwood stand on steeply sloping ground. Visualization
tools were found to be most suited to placing small leave strips
within larger clearcuts for obscuring some areas from view and
giving the impression of a series of smaller cutting units.

ABSTRACT: Clearcutting, a silvicultural process described by
Pinchot as "the easiest of them all to apply", is described
within complex current economic, environmental, and social constraints.
Economics is shown to be the major factor favoring the practice,
but continued prescribed use is supported by biological, environmental,
and ecological factors as well. The paper suggests that most resistance
to clearcutting originates from visual and aesthetic concerns.
Compromise in the use of clearcutting is foreseen as likely on
some land holdings but with undesirable results if the ecological
requirements of preferred species of plants and wildlife are not
met.
