The lack of growth and yield information for young even-aged western hemlock

(Tsuga heterophylla (Raf.) Sarg.)-Sitka spruce (Picea sitchensis (Bong.) Carr.)

stands in southeastern Alaska served as the impetus for a long-term stand-density

study begun in 1974. The study has followed permanent growth plots in managed

stands under various thinning regimes. Between 1974 and 1987, 272 plots were

established at 59 locations throughout southeastern Alaska. Remeasurement of the

plots occurs every two to four years and will continue until harvest. Additional thinnings will occur on a portion of the plots. Future plans include extending the study

through establishment of installations in stand types not currently represented. Once

data for an entire rotation are obtained, a comprehensive set of growth and yield

tables for various management regimes can be developed. This information will

answer questions forest managers have on whether and when to thin a stand, at

what level of intensity, and how frequently to enter the stand. 

Keywords: Thinning, stand density, southeastern Alaska, western hemlock, Sitka

spruce.

Extensive harvesting of old-growth stands in the Tongass National Forest began in

the 1950s. A sufficient number of young-growth stands were not available to initiate

a comprehensive growth and yield study until the 1970s. In 1974 research began to

study the effects of stand density on the growth and yield of young even-aged hemlock-spruce stands in coastal Alaska. The main objectives of the study are to:

• Obtain information on tree growth following thinning of dense, unthinned stands of

western hemlock and Sitka spruce.

• Integrate findings into a set of interim stand growth and yield tables based on the

following independent variables: site, age, density, and possibly species composition.

• Obtain information over an extended time on the development of stands under

various thinning regimes that might be applied in the future and refine the interim

estimates.

The study plan design called for the distribution of installations in well-stocked,

even-aged western hemlock-Sitka spruce stands across three broad site classes

and four stand age classes so that the effects of site index and stand age at the

time of thinning could be investigated. Four 1-acre plots (each with a 1/5-acre

interior measurement plot) were established at each installation and randomly

assigned one of four treatments: control (no thinning) or light, medium, or heavy

thinning. Each installation was to be replicated four times so that different management treatments could be applied to replicates sometime in the future. Tree spacings were not held constant for a specified treatment; the number of trees per acre

left after thinning for a given treatment is determined not only by the thinning intensity applied to a plot but also is dependent on the quadratic mean diameter of the

Summary
stand before thinning. By treatment type, the average amount of basal area removed

was 47.7 percent on lightly thinned plots, 60.9 percent on medium thinned plots, and

73.5 percent on heavily thinned plots.

Data collected to date represent only the growth response of trees immediately

after thinning. Growth of residual trees is usually rapid immediately after thinning

but slows with the closure of the forest canopy, increasing tree competition, and

advancing tree age. More data are needed before the shapes of the basal area

and volume growth curves over stand age can be determined for various combinations of site index and thinning treatments. Results from this study will increase

in value the longer the research plots are followed.

Preliminary observations from the stand-density study are, first, precommercial

thinning is usually beneficial and, in most cases, necessary when managing for

wood production—the reduction of competition enhances stand volume growth.

Second, stand basal area can be severely reduced with little mortality of leave

trees; tree mortality in thinned stands is minimal and seems to be unrelated to

the amount of basal area removed. Third, medium to heavy thinnings should be

favored when treating stands for wood production, based on the speed of crown

closure and the resumption of tree competition that occurs in lightly thinned plots.

Fourth, heavy thinning usually reduces stand gross volume yield and could reduce

wood quality but may benefit wildlife by allowing the development of understory

vegetation.
Introduction The hemlock-spruce forest type occupies the coastal mountains of Oregon,

Washington, British Columbia, and southeastern Alaska. The north-south range of

the forest type is about 1,800 miles long, with a limited east-west range extending

inland from the coast about 25 to 30 miles in Oregon and Washington, 100 miles in

British Columbia, and 130 miles in southeastern Alaska (Meyer 1937). High precipitation, frequent fogs, absence of summer droughts, moderate temperatures, and

mild winters are typical climatic characteristics found within the range of the hemlock-spruce forest type. Within this forest type, the most favorable growing conditions are along the northern coast of Oregon and coastal Washington. Productivity

declines as the range extends north from Washington, but even at the northern end

of the range, growing conditions are more than adequate for the development of

high-volume stands.1

Across the Tongass National Forest in southeastern Alaska, annual precipitation

averages 120 inches, ranging from a low of 50 inches in the northwest to 160 inches

around the Ketchikan area. Annual average temperatures are around 41 °F, summer

temperatures average 55 to 60 °F, the lowest winter temperature is between 20 to 

30 °F, and the number of frost-free months is about nine (Meyer 1937).

The Tongass National Forest has a land area of about 17 million acres with 10

million acres forested. Of the forested acres, 4.3 million acres are not capable of

producing industrial forest products, and 5.7 million acres are considered to be

productive forest lands biologically capable of producing industrial wood products

and are classified as old growth. Land dedicated for the production of wood fiber

was 4.1 million acres in 1980 but had been reduced to about 670,000 acres by

1997. The land base for wood production contains about 500,000 acres of oldgrowth forest and 170,000 acres of young-growth stands. Almost all the younggrowth stands have been created since the 1950s through clearcut harvesting, 

but some scattered young-growth stands date to the 1930s. 

Major issues for the Tongass National Forest include the amount of wood volume

harvested each year, the method of harvest, sustainability of harvest, location of

harvest areas, and the impact harvesting has on other forest resources and uses.

These issues, along with a limited landbase dedicated to wood production, point

out the need for accurate information on the growth and yield of young managed

stands, possible alternative silvicultural treatments, impacts of various harvest

methods on other forest resources, and how best to reduce impacts while satisfying demand for wood products. This study will provide estimates on the growth and

yield of young, even-aged managed stands to serve as guidelines for even-aged

management and to provide standards to evaluate relative costs and benefits of

alternative silvicultural treatments.

Regeneration of hemlock-spruce stands usually is not a problem in southeastern

Alaska (Harris and Farr 1974). Favorable site and climatic conditions and frequent

seed years produce dense regeneration within a short time after harvesting activities.

Most of the time, regeneration is so dense that severe competition for light, nutrients,

and growing space quickly develops among individual trees. Young, even-aged

stands of spruce and hemlock are not generally thought to stagnate because mortality rates are high, but a great deal of wood volume is lost as growth is placed

on many individual trees that eventually die and are never used for wood production. Typical young, even-aged stands are overstocked for optimum development,

and some form of stand-density control is a desirable management activity when

production of wood products is the desired goal.

Guidelines for the management of young, even-aged, thinned hemlock-spruce

stands in southeastern Alaska are limited. Yield tables for unmanaged secondgrowth western hemlock (Tsuga heterophylla (Raf.) Sarg.)-Sitka spruce (Picea

sitchensis (Bong.) Carr.) stands of southeastern Alaska were developed by Taylor

(1934), who used data from 288 temporary plots established in even-aged stands

of normal stocking. Meyer (1937) used Taylor’s plot data and additional temporary

plot data from British Columbia, Oregon, and Washington to develop tables that

applied to the geographic range of the western hemlock-Sitka spruce type. Barnes

(1962) produced new growth and yield tables for western hemlock after it became

apparent that Meyer’s tables did not allow for regional discrepancies in yields and

site index that occurred within the range of the forest type. Hemlock-spruce stands

in Alaska have more stems per acre, smaller average diameter, and less volume

than stands in the Pacific Northwest (Barnes 1962). Whether the perceived

decrease in productivity is related to overstocking remains unclear.

Barnes (1962) used Meyer’s Oregon and Washington data plus new data from

Oregon, Washington, British Columbia, and southeastern Alaska as the basis for

revision of the western hemlock yield tables. Barnes screened the plot data to

ensure that 40 percent or more of the basal area was western hemlock and from

this screened data produced separate growth and yield tables for OregonWashington, British Columbia, and southeastern Alaska. Chambers and Wilson

(1972) developed yield tables for coniferous stands in the western hemlock type

of western Washington that are applicable only to stands where western hemlock,

Sitka spruce, and western redcedar (Thuja plicata Donn D. Don) are the primary

species. All the tables from these publications forecast net yield of young, unmanaged stands but are not applicable in predicting growth and yield of intensively

managed stands.

Methods of Study

Area

A search of the literature revealed little information on the growth and yield of managed even-aged western hemlock-Sitka spruce stands. Hoyer (1967) converted British

thinning yield tables for managed pure western hemlock stands to American units of

measure. Dilworth (1980) gives growth statistics for the first 10 years following precommercial thinning of western hemlock stands in the Oregon Coast Range; the precommercial thinnings were conducted in 18- to 22-year-old stands and produced four

levels of growing stock. Hoyer and Swanzy (1986) present results of two studies of

thinned western hemlock stands in Oregon and Washington. Omule (1988) reports on

the early growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock, Sitka spruce, and western redcedar at three spacings on Vancouver Island. All

these publications present results for specific geographic areas and are limited in

scope as to the site index range covered, age of the stands at the time of thinning,

and number of spacing treatments tested. None of the results can be used in southeastern Alaska to guide management of young, even-aged stands of hemlock-spruce.

Potential study sites along with information on the location, size, stand origin, and

stand age of each site and the range of site index of each site were provided by

National Forest System personnel. Each potential site was evaluated based on this

information and other needs of the stand-density study (see footnote 1). Candidate

study areas were identified and ranked as to their possible inclusion in the study.

Actual plot locations were established after site reconnaissance by a team consisting of a soil scientist, mensurationist, timber staff officer, and a specialist in entomology and pathology. A location was selected as a study site if the stand was of

logging origin, was even aged, was located on a single soil series, was free of

large residual trees, had uniform stocking, and was well stocked (basal area within

± 15 percent of estimated normal). Stands had to be of sufficient size to accommodate four 1-acre plots. After it became apparent that there were not enough older

stands of logging origin to meet the needs of the study, the stand origin criteria for

older stands (30 years or more) were expanded to include stands originating from

fire or blowdown.

The installation distribution reflects the harvesting patterns from the 1950s onward,

which were concentrated in the Ketchikan Area, followed by the Stikine and Chatham

Areas. More young-growth stands were available for the establishment of installations in the southern part of the Tongass. There are 31 installations in the Ketchikan

administrative area (fig. 1), 19 in the Stikine Area (fig. 2), and 9 in the Chatham

Area (fig. 3).

Design The study plan called for the establishment of 192 permanent growth plots in 

well-stocked, even-aged western hemlock-Sitka spruce stands at 48 installations

throughout the Tongass. Installations were to be distributed across three broad

site classes and four stand age classes so that the effects of site index and stand

age at the time of thinning could be investigated. Usually, four 1-acre plots (each

with a 1/5-acre interior measurement plot) were established at each installation

(location) and randomly assigned one of four spacing treatments (no thinning or

light, medium, or heavy thinning). Each installation was to be replicated four times

so that different management treatments could be applied to replicates sometime

in the future. 

All plots were in stands of uniform tree spacing with no large holes in the forest

canopy. A typical measurement plot in the study is square, one-fifth of an acre in

size, and surrounded by a buffer that extends to a square 1-acre area (fig. 4) to

minimize border effects. Because the ranges of site, stand age, and residual density

are quite wide, several plot sizes were considered for the study. There is no single

most desirable plot size, but it was determined that a plot size of one-fifth of an acre

was satisfactory. 

Usually, too many trees occur in young, unthinned stands of hemlock-spruce to

measure in a reasonable amount of time on a 1/5-acre plot; therefore nine interior

points were located within the plot (fig. 4). All trees taller than 4.5 feet within a circular 4-milacre plot centered on each interior point were measured. The interior points

were used as sampling points for selecting sample trees in young unthinned stands

and also as sampling points for a related study on understory vegetation. For larger

diameter stands with fewer trees, all trees on the 1/5-acre plot were tallied before

and after treatment. All residual trees on thinned plots were tallied and measured.

Access trails to the plots were cut and then marked with yellow flagging. Aluminum

pipes were used to mark the corners of the 1/5-acre plots, and permanent aluminum

stakes sprayed with blue paint and tied with red flagging were used to mark the nine

interior points. Trails along the boundaries of the 1/5-acre plots also were cut and

marked with yellow paint to facilitate access to trees within the plots. Trees along the

plot edges were marked with blue paint to delineate boundaries for the full 1-acre

plots. 

For each installation, number and name were recorded along with longitude

and latitude, stand origin, and comments on any unusual stand characteristics.

A map of the installation’s location, individual plot locations within the installation, and access trails was drawn. Boundaries of individual plots were documented by recording compass bearings and length of plot sides. Plot number,

plot size, elevation, aspect, steepness of slope as a percentage, position on

slope, habitat type, soil characteristics, and pertinent comments about individual

plots also were recorded.

nine permanently marked sampling points.
Treatments Random numbers were drawn and used to assign thinning treatments (none, light,

medium, or heavy) to plots. All live sample trees within a plot were tallied by species

and by 1-inch diameter classes. In dense young stands, a sample tree had to have

a diameter 0.6 inch or larger and be located in one of the nine 4-milacre point plots.

In older and less dense stands, all trees 0.6 inch or larger on the 1/5-acre plot are

sample trees. From these data, the before-thinning stand characteristics of number

of trees per acre, basal area per acre, and quadratic mean diameter (QMD) were

calculated for each plot. 

Quadratic mean diameter of the stand before thinning, selected thinning intensity,

and the appropriate thinning guide (table 1, 2, or 3) were used to determine the

desired basal area, number of trees, and average spacing of trees after thinning.

Guide tables for thinning were constructed from information gathered in marking

plots for thinning in 1974 and 1975.2 Table values for desired basal area and number of trees left after thinning were derived from the assumption that large-diameter

stands should be thinned more conservatively than stands of small or average

diameter.

Using the tables to determine after-thinning values is relatively easy. For example,

if a medium-intensity thinning treatment is assigned to a plot having a 9.0-inch average diameter before thinning, then table 2 shows the average diameter after thinning is estimated to be 12.2 inches, the number of trees per acre after thinning is

203, and the desired basal area after thinning is 165 square feet per acre. For a

1/5-acre plot, 41 equally spaced leave trees would produce about the desired basal

area. 

To mark the 41 leave trees in this example, the plot is divided into four strips with

10 leave trees selected per strip and 1 additional tree selected in the plot to

achieve the desired number. Diameters of marked trees are measured and the

basal area per acre of the plot calculated and compared to the target basal area.

Adjustments in the selection of some leave trees might be needed if plot basal

area does not meet the desired basal area level. Buffer strip (outer 0.8 acre) leave

trees also are marked according to the same marking guides as for the 1/5-acre

measurement plot.

Implementation Tree marking guidelines were designed to leave the best growing stock on the plot.

Thinnings in older stands concentrated on improving spacing of overstory trees and

removing merchantable size trees contributing little to stand growth. Thinnings in

young stands focused on the removal of rough, limby dominants of poor tree form

and quality and on improving growing space around selected crop trees. Thinnings

in young stands were precommercial, almost all removed trees were nonmerchantable in size. 

After tree marking was completed, all leave trees (except small trees) were pruned

to 6 feet. They were numbered with aluminum tags and nails and marked with a

band of blue paint at stump height and breast height. A line was painted at breast

height (4.5 feet) to establish where all future diameter measurements would be

made, and tree numbers were painted on the stem above breast height to facilitate

locating trees during remeasurement. Measurements were taken from sample trees

in the control plot and from all marked residual trees in plots scheduled for thinning.

Species, diameter to the nearest one-tenth of an inch, crown class, tree class,3 tree

damage location (if any), severity of damage, and general and specific causes of

damage were recorded for each tree. A subsample of trees (10 to 15 trees of each

species) was selected across the range of diameters in the stand with about twothirds of the sample being above QMD. Subsample trees were measured for total

height and height to live crown. A stem map of selected residual trees on the 1/5-

acre measurement plot also was made at this time. This map is used to help locate

residual trees after thinning to check for mistakes in tree removal. It is also used to

help locate trees during remeasurement and might be used during data analysis to

establish spatial relationships. 

The Alaska Region of the National Forest System arranged and supervised most

of the thinning operations. Thinnings were completed before the first growing

season after establishment of an installation. All thinned trees of commercial size

were removed from most 1-acre plots to simulate a commercial thinning operation.

Unfortunately, it was not possible to simulate the disturbance a stand would experience from equipment used in normal commercial thinnings. Removal of merchantable trees from research plots was accomplished either by hand or with

portable yarding equipment. 

A tree was considered to be of commercial size if its diameter at breast height (d.b.h.)

was 9.6 inches or larger and it contained at least one 16-foot log with a small-end

diameter (outside bark) of 5 inches. Trees not meeting the merchantability definition

were not removed after cutting and were left where they fell. Thus, for plots located in

young stands with no trees of commercial size, thinnings actually mirrored precommercial thinnings. An exception is installation 61 where plots were “thinned” by girdling

select “cut” trees and not by cutting. Many trees marked for thinning on these plots

were trees of poor stem form that had large crowns with many large limbs. Selected

leave trees would have been seriously damaged had these large trees been felled;

therefore, girdling was used to avoid this type of damage. It is unknown what effect

“thinning” trees by girdling (instead of cutting) will have on results; this will be investigated when the data are analyzed.

3 Tree classes are live, live cut, dead, ingrowth, new tree, 

dead cut, live tree, site and crop tree, site tree, and crop tree.

13
Measurements After

Thinning

All plots on an installation were remeasured immediately after thinning and before the

next growing season. This provided an opportunity to verify that trees selected for cutting were removed and those marked for retention actually remained. The postthinning

measurement ensured the accuracy of initial plot and tree data. Measurement standards were identical to those used to measure the plots after marking. For each tree,

the species, diameter to the nearest one-tenth of an inch, crown class, tree class, tree

damage location (if any), severity of damage, and general and specific causes of

damage were checked for accuracy. Sample height trees were remeasured to confirm previous measurements of total height and height to live crown. The sample of

height trees does not change from one remeasurement to the next; the same trees

are measured for height each time. The sample of height trees can change, however, when a height tree dies or experiences top damage; it is replaced by another

tree. Replacement trees should be comparable in diameter, crown class, and height

to the tree being replaced. 

Remeasurement cycles for plots differ over time and from installation to installation.

Plots in installations established at the start of the study were measured every year

for 3 years after thinning. After inclusion of more installations, it became apparent

that plots did not need to be measured this frequently, and a remeasurement cycle of

2 years became the standard for recently thinned plots. Most installations, however,

had to be remeasured every 2 years because the fast growth of tree diameters on

thinned plots required that nails holding tree tags be pulled so that the tags would not

become embedded in the wood. Remeasurement schedules for installations change

to a 4-year cycle as tree diameter growth slows with increasing stand age and stand

density. 

A comprehensive statistical analysis of the stand density data is in the planning

stage. A preliminary examination of the data has revealed that the data structure

limits hypothesis testing and the use of analysis of variance. Tree spacing was not

held constant for a specified treatment. The number of trees per acre left after thinning for a given treatment is determined not only by the thinning intensity applied 

to a plot but also depends on the QMD of the stand before thinning. Because tree

spacing is not the same across the ranges of site index and stand age for a given

treatment intensity (light, medium, or heavy thinning), analysis of variance cannot

be used on the complete data set.

Regression analysis will have to be used to analyze the data. The development of 

a set of interim growth and yield tables, one of the objectives of the study, will occur

when data representing the growth response of stands over a sufficient period have

been collected. Even though the current data will not allow development of equations to predict growth and yield over the entire length of a rotation, regression

equations that predict growth responses of thinned stands for a limited, 20- to 

30-year period after thinning can be derived. The analysis along with results will 

be published when completed. 

To date, most of the research activity in the stand density growth study has centered

on establishment, measurement, and remeasurement of plots; data editing; database management; and the production of stand summary tables. Fieldwork started

in spring 1974 with establishment of 21 plots at six locations (installations). The

majority of installations and plots were established between spring 1974 and fall

14

Progress and Status 
1977, with 163 plots at 44 installations being located, thinned, and measured. Another

15 installations and 109 plots were established between 1978 and 1987 as new areas

were located, evaluated, and selected for inclusion into the study. A total of 272 plots

at 59 locations have been established since 1974. 

At the time of establishment, all installations were located on land managed by

the USDA Forest Service. This changed when the City and Borough of Juneau,

the State of Alaska, and Alaskan Native corporations exercised their rights to

select and acquire ownership of about 1.7 million acres of National Forest land.

Fourteen installations are now located on city, state, and Native corporation land:

City and Borough of Juneau 1

Kake Tribal Corp. 1

Kavilco Corp. 3

Sealaska 1

Klukwan, Inc. 3

Agreements between owners of the land where installations occur and the Pacific

Northwest Research Station have been made to allow remeasurement of plots. 

Four installations no longer exist: one was destroyed by road construction in 1985

and three were harvested in 1997. Two of the harvested installations became part of

a research study designed to evaluate the wood quality potential of young-growth

western hemlock and Sitka spruce. Scientists from the USDA Forest Service Forest

Products Laboratory, Madison, Wisconsin, and the Pacific Northwest Research

Station’s Portland and Juneau Forestry Sciences Laboratories are conducting this

study.

Additional data have been included in the stand density database. Remeasurement

data for 12 plots (from 9 locations) established in unmanaged stands by Taylor in

the late 1920s, early 1930s, and 1963 have been entered into the database. All

locations, except one, are being remeasured on a 5-year cycle. The one location

not on this remeasurement schedule was terminated in 1964. As of 1998, three of

Taylor’s plots (one location) are about 70 years old (total age), and the rest of

Taylor’s plots are between 100 and 170 years of age. Site index at index age 100

ranges from 70 to around 110 and stand QMD ranges from 14 to 22 inches.

Locations of Taylor’s plots are shown in figures 1, 2, and 3.

Table 4 shows the actual distribution of plots over the ranges of site indexes, stand

ages, and thinning treatments. Stand age is total age, and site index4 is the average

height of dominant trees at index age 100 as defined by Taylor (1934). From table 4,

it is evident that the planned distribution of four plots per cell was not achieved. Few

plots are located in areas with a site index under 100, and thinnings for stand ages

above 60 years are not fully represented. This result is not unexpected given that

most harvesting in the Tongass National Forest within the last 50 years has occurred

4 The calculation of site index is explained more fully in the 

appendix of this report.

on more productive sites. Very few young-growth stands of logging origin were older

than 60 years, and very few young stands of low productivity existed in the Tongass

when the stand-density plots were established. Most logging in the Tongass has

occurred at lower elevations where sites tend to have better growing conditions and

productivity is higher. Logging of the lower elevations first was probably a consequence of a combination of economics, management objectives, and the fact that

road systems start at tidewater and usually follow valley bottoms; then, at a later

date, they branch out to upper elevations where poorer growing conditions exist.

The appendix of this report contains one or more tables for each installation in the

study and presents before-thinning (when available) and after-thinning stand statistics for each plot in the installation. The following summary information on initial

stand conditions was compiled from the tables in the appendix. Total age of stands

at the time of thinning ranged from 10 to 93 years with about 80 percent of the

stands being under age 50 (fig. 5). Site index at a breast height index age of 50

years ranged from 43 to 120 (Farr 1984), and site index based on a total index age

of 100 years ranged from 74 to 165 (Taylor 1934). There are substantially more

plots with high site indexes than low site indexes (figs. 6 and 7). As stated previously, this reflects the history of harvesting in the Tongass, which limited the range

of site indices that could be selected for the study and produced a sample skewed

toward the more productive stands. With the exception of one installation located 

at 1,500 feet in elevation, all plots were below 500 feet.

The number of trees per acre on unthinned (control) plots ranged from 340 to

13,028. The number of trees per acre on treatment plots before thinning ranged

from 230 to 11,528 and after thinning ranged from 80 to 680. Quadratic mean diameter in stands before thinning ranged from 0.9 inch to more than 15.0 inches. The

proportion of Sitka spruce present in stands ranged from 0.5 to 100 percent. In control plots, about 28.8 percent of the trees were Sitka spruce at time of plot establishment; in treatment plots, stands averaged 29.3 percent spruce before thinning. This

difference in species composition between control plots and plots selected for treatment is insignificant.

Thinning treatments were randomly assigned to plots in an installation—there was

no attempt to use stand attributes to determine treatment type. Treated plots averaged 41.4 percent Sitka spruce after thinning. Thinning guidelines did not intentionally favor Sitka spruce but did favor the selection of larger diameter and faster

growing trees. This caused an increase in the percentage of spruce in stands after

thinning because young spruce trees tended to be larger than young western

hemlock trees (Taylor 1934).

At the time of plot establishment, basal area per acre on control plots ranged from

13.8 to 418.5 square feet. On plots selected for treatment, stand basal area before

thinning ranged from 8.9 to 467.7 square feet. Basal area removed by thinning

ranged from 8.2 to 94.5 percent with an average of 61.9 percent. By treatment type,

the average amount of basal area removed was 47.7 percent on lightly thinned

plots, 60.9 percent on medium thinned plots, and 73.5 percent on heavily thinned

plots.

Discussion and

Conclusion

Forest managers have many management alternatives to choose from following

removal of old-growth stands. Some areas will not be reentered before being harvested again, and other areas will be intensively managed throughout the next

rotation. Known outcomes of various silvicultural treatments are needed so that

managers can fulfill their management objectives while limiting impacts to other

forest resources. Forest managers have many questions: At what age should

unthinned stands be thinned for both wood quality and volume yields? What level

of basal area should be left after thinning? How frequently should thinning occur

during a rotation? How will unthinned stands of various ages and sites respond to

thinning? What effects do stand density and species composition have on volume

growth and tree size for different combinations of site and stand age? What is the

influence of stocking on the height-age relation?

Data from the stand density study was used to develop the forest vegetation simulator, SEAPROG, the southeastern Alaska variant of Prognosis (Stage 1973), an

individual tree, distance-independent growth and yield model developed for use

in Idaho and Montana. Alaska forest managers and silviculturists use SEAPROG

for forestwide management. The accuracy of SEAPROG’s even-aged growth and

yield predictions and ability to model alternative silviculture regimes are regularly

evaluated and modifications made when needed. Calculated stand statistics and

individual tree data from the stand-density study will continue to be used in evaluation and development of SEAPROG and its eventual upgrade to simulate a

variety of uneven-aged silvicultural alternatives. 

Preliminary observations can be made from examination of the tables presented in

the appendix. First, precommercial thinning is usually beneficial and, in most cases,

necessary when managing for wood production. Unthinned stands of spruce and

hemlock are extremely dense owing to the high number of seedlings that occur

naturally after harvesting—several thousand trees per acre are not uncommon in

young stands. Many years must pass before adequate tree mortality allows the

dominant trees in a stand to realize their growth potential. A high volume of wood

is lost in unmerchantable, suppressed trees that eventually die. Competing trees,

in some situations, are barely existing and use valuable soil nutrients to grow

minimal amounts of wood. Reducing this competition enhances stand volume

growth.

Second, stand basal area can be severely reduced with little mortality of leave trees.

In one instance, as much as 94.5 percent of basal area was removed from a plot

without any mortality occurring in the leave stand. Tree mortality in thinned stands

is minimal and seems to be unrelated to the amount of basal area removed. 

Third, medium to heavy thinnings should be favored when treating stands for wood

production. This recommendation is based on the speed of crown closure and the

resumption of tree competition that occurs in lightly thinned plots. In many cases,

stand characteristics of lightly thinned plots visually appear to be very similar to

unthinned stand conditions. Young, lightly thinned plots also start to experience tree

mortality 10 to 15 years after thinning, before the stand reaches merchantable size.

Last, although heavy thinning usually reduces stand volume yield and could reduce

wood quality (fewer growth rings per inch, larger knots, etc.), it may be a benefit to

wildlife. With wider spacing, fewer crop trees will be left for volume growth, and the

19
Future Study Plans

greater abundance of ingrowth trees and understory vegetation would compete with

and, for a short time, might overwhelm selected leave trees in young stands. Wood

quality might be affected because natural pruning that occurs with crown closure

takes longer in stands with wider spacings; leave trees probably would have more

and larger limbs. As stated previously, a wood quality study of trees located on the

stand density growth plots is now being conducted; results from this study are not

yet available.

Heavy thinnings that leave extra wide spacings between trees might benefit wildlife

by allowing the development of understory vegetation. Understory vegetation in

plots with widely spaced trees is usually abundant the first few years after thinning.

How long this abundance lasts and the quality of the vegetation for wildlife forage

still need to be determined. Deal and Farr (1994) report on the occurrence of conifer

regeneration on the stand density plots after thinning. They concluded that thinning

of young stands on upland sites appears to benefit understory conifers that rapidly

expand to fill available growing space. Also, they concluded that heavy thinnings in

older stands promote prolific germination of coniferous seed, thereby making it difficult for other understory plants to become established. Other research conducted in

the stand density plots has focused on the development of understory vegetation

and has resulted in many reports (Alaback 1984, 1986, 1987, 1988). Alaback (1984)

concluded that silvicultural thinnings might enhance understory productivity in

young, even-aged stands and that repeated thinnings during a rotation probably will

be needed to maintain a high rate of understory productivity for wildlife purposes. 

Plots will continue to be followed with remeasurement cycles being lengthened to

at least 4 years as tree growth slows. The importance of continuing to remeasure

plots cannot be overstated. Some installations in the study have been followed for

24 years, and other installations have only 10 years of remeasurement data. This

is still a relatively short period of observation when trying to predict the growth of

trees over a 100-year rotation. Data collected so far represent only growth response

of trees immediately after thinning. Growth of residual trees is usually rapid immediately after thinning but slows with the closure of the forest canopy, increasing tree

competition, and advancing tree age. Thus, many more years of data are needed

before the shapes of the basal area and volume growth curves over stand age can

be determined for various combinations of site index and thinning treatments. Results

from this study will increase in value the longer the research plots are followed. 

The study needs to be expanded by establishing installations in stands at higher

elevations and in stands of lower productivity. As stated before, there is only one

installation above 500 feet, and few installations are located in low-productivity

stands. These deficiencies in the database should be corrected, if possible. Adding

these types of installations to the study might prove difficult, however, because few

young stands exist at upper elevations where site productivity tends to be lower.

Creation of new young-growth stands at higher elevations also might not occur

given that the number of acres dedicated for wood production has decreased and

that alternatives to clearcutting methods might be used to harvest stands in the

future. Additional installations will be established, however, whenever suitable

young, even-aged stands are located and funds are available.

20
Plans call for the application of commercial thinning treatments to installations after

plots recover (based on crown closure) from initial management treatments and

trees grow to merchantable size. The goal of the original study design was to have

four replicates of each initial thinning treatment distributed across three site classes

and four stand age classes. Different commercial thinning regimes were to be

imposed on three of the replicates with one replicate left untouched as a control.

This design cannot be followed completely because the actual distribution of plots

by thinning treatment over site and stand age classes does not contain four replicates in each cell. Stands with site index greater than 100 are well represented

while stands with site index under 100 are scarce. Also, stand age classes 50 years

and younger are represented by many installations, but age classes greater than 50

years have few observations. Application of commercial thinning regimes will probably be limited to a subset of installations; the subset sample of installations will be

selected when sufficient stands reach merchantable size. 

It is recommended that this study be continued until all installations are harvested.

Data are needed for an entire rotation so that a comprehensive set of growth and

yield tables for various management regimes can be developed. The importance of

this study cannot be overstated. Reductions in the land base dedicated to growing

timber in the Tongass and expected increases in future demand for wood dictate

that stands grown for wood be managed for maximum production. Results from this

study will provide some of the information needed by managers to achieve this goal.

This information also will be useful to Alaska Native corporations, the State of

Alaska, and other government entities in managing about 1.7 million acres of forested

land. Native corporations in southeastern Alaska control about 600,000 acres of

forested land with much of it in young growth. Maximizing wood production on

these acres would ease the demand for wood from the Tongass National Forest.

Results from the stand density study also will be needed to help evaluate results

from the alternatives-to-clearcutting study now being conducted by scientists at the

Forestry Sciences Laboratory in Juneau. Estimates of the growth and yield of evenaged stands and the associated costs of even-aged management will provide a

measure of the benefits and costs of alternative treatments. Even-aged management is the most economical method of managing forest stands for wood products;

road building and logging costs are at a minimum and wood production is maximized. Alternatives-to-clearcutting methods are expected to have higher harvesting

costs and produce less wood each time a stand is entered. Comparing costs and

results could help managers decide what kind of harvesting method should be

applied to a particular stand.

Appendix Tables presented in this appendix give before-thinning (when available) and afterthinning stand statistics for each plot in an installation at the time of establishment.

Table headings are generally self-explanatory except for the following: CCF = crown

competition factor as defined by Krajicek et al. (1961), and the values were calculated by using equations from Farr et al. (1989); SDI = stand density index (Reineke

1933); ASP = plot aspect in degrees; and %SLP = the angle of slope as a percentage. 

Site index at total age 100 years is based on Taylor’s (1934) site curves, and site

index at breast height age 50 years is based on Farr’s (1984) site index equations.

When plot age (breast height age for Farr's site index and total age for Taylor’s site

index) was less than the index age of the curves being used, site index was determined from the most recent height measurements and plot age. If plot age was

greater than the index age of the site curves, then site index was calculated by

interpolation. Site index estimates for hemlock and Sitka spruce were averaged

together to obtain an overall site index for plots having both species present in the

stand’s overstory. 

Plots in an installation usually were established in the same year; however, some

installations have plots established in different years. The “comments” section in

each table documents whether plots were established in the same year.
