This report is a summary of timber resource statistics for all ownerships in Oregon. Data 

were collected as part of several statewide multiresource inventories, including those 

conducted by the Pacific Northwest Region (Region 6) on National Forest System lands in 

Oregon, by the Bureau of Land Management (BLM) on BLM lands in western Oregon, and 

by the Pacific Northwest Research Station Forest Inventory and Analysis (FIA) Program on 

BLM lands in eastern Oregon and state and private lands across Oregon. Statistical tables 

provide estimates of land area, timber volume, growth, mortality, and harvest for the state 

and half-state units (western and eastern Oregon).

Keywords: Forest inventory, statistics (forest), timber resources, timberland, resources 

(forest), Oregon, western Oregon, eastern Oregon.

Summary

Oregon has an estimated 61 million acres of land. About 49 percent of this land is forested 

with 76 percent of the forested portion being nonreserved timberland. About 58 percent of 

the timberland is managed by national forests and other federal agencies, 4 percent is managed by state and local agencies, and 38 percent is privately owned. Douglas-fir is the most 

common forest type in western Oregon forests, and ponderosa pine is most common in 

eastern Oregon forests. Younger stands (0-60 years) predominate in western Oregon, and 

older stands (80-199 years) predominate in eastern Oregon. The net volume of growing 

stock on all timberland is 78 billion cubic feet, with 91 percent of this from softwoods (coniferous species). About 71 percent of the growing-stock volume is on public land, 

19 percent on forest industry land, and 9 percent on other private land. Estimated net 

annual growth of sawtimber is 1,689 million cubic feet, estimated average annual mortality 

is 444 million cubic feet, and average annual removals are 1,045 million cubic feet (4,710 

million board feet).

Timber Resource Statistics for Oregon

Introduction

This report summarizes the timber resource statistics 

for Oregon’s forests. It uses data from forest inventories 

conducted in Oregon in the 1990s: the 1998–99 Pacific 

Northwest Forest Inventory and Analysis (PNW-FIA) 

inventory of eastern Oregon, the 1994–98 PNW-FIA inventory of western Oregon, the 1993–96 Pacific Northwest 

Region (Oregon and Washington national forests) inventory, 

and the 1997 Bureau of Land Management (BLM) inventory 

of western Oregon. Other resources sampled but not included in this report include understory vegetation, crown cover, 

insects, diseases, coarse woody material, and snags. These 

data will be analyzed and reported in other publications.

The PNW-FIA unit has been reporting statistics for 

Oregon since the 1930s. Bolsinger and Berger (1975), 

Farrenkopf (1982), Gedney et al. (1989), and Azuma et al. 

(2004b) reported inventory statistics in the 1960s, 1970s, 

1980s, and 1990s, respectively, for eastern Oregon. Hazard 

and Metcalf (1964, 1965), Metcalf and Hazard (1964), 

Bassett (1977), Jacobs (1978), Mei (1979), Gedney et al. 

(1986a, 1986b, 1987), and Azuma et al. (2004a) reported 

inventory statistics in the 1960s, 1970s, 1980s, and 1990s 

for western Oregon. Inventory and reports from the 1970s 

on did not include BLM land in western Oregon or any 

Oregon national forests. The current sampling system is a 

systematic grid of plots, established in the early 1960s by 

PNW-FIA for areas outside of national forests and in the 

1990s by Pacific Northwest Region (Region 6) and BLM for 

national forests and western Oregon BLM land, respectively. 

Azuma et al. (2004a, 2004b) used 1999 and 1998 PNW-FIA 

data sets to report the latest forest statistics for eastern and 

western Oregon, respectively.

This report contains statistical tables that provide 

current estimates of forest land and timberland area (see 

“Glossary”), timber volume, growth, mortality, and harvest. 

The national forest statistics include areas that are withdrawn from timber production but still meet the FIA definition of timberland. National forest land is not all equally 

available for timber production owing to various management decisions (see “Reserved Area,” p. 8). Estimates of 

change in volume and area of nonfederal land between the 

1980s and the present inventory are reported in Azuma 

2004a and 2004b.

Highlights

Forested Area

The state of Oregon encompasses over 61 million acres. 

About 49 percent of the area is forest land; of this, 76 

percent is nonreserved timberland (figs. 1–3, app. table 1). 

Western Oregon (from the crest of the Cascade Range west 

to the Pacific Ocean) has 15.4 million acres of forest land 

with 87 percent of it classed as nonreserved timberland, and 

eastern Oregon (from the crest of the Cascade Range to the 

eastern border of the state) has 14.8 million acres with 65 

percent nonreserved timberland. Eastern Oregon forest land 

includes about 2 million acres of juniper forest land surveyed in the 1980s (Gedney et al. 1999)

Forest Land Ownership

The National Forest System (NFS), the BLM, and other 

federal agencies manage about 59 percent of the forest land 

(58 percent of the timberland) in Oregon. Owners classed as 

forest industry manage about 21 percent of the forest land 

(25 percent of the timberland); nonindustrial private owners 

and other public owners manage about 16 and 4 percent of 

forest land (13 and 4 percent of timberland), respectively. 

See figures 4 and 5, and appendix tables 2, 3, and 5.

Northwest Research Station, Forest Inventory and Analysis Program (FIA), Portland, Oregon, by using U.S. Geological 

Survey (USGS) Multiresolution Land Characterization Consortium (MRLC) land cover classification data based on 

1992 Landsat Thematic Mapper (TM) satellite imagery and land ownership information derived from the Gap Analysis 

Project (GAP). 

Forest Type

Forest type refers to the dominant tree species in a stand. 

The majority of Oregon forest land (and timberland) is dominated by softwood forest types (83 percent), with Douglasfir the most abundant type in western Oregon and ponderosa 

pine in eastern Oregon (fig. 6). Appendix tables 3 and 4 

display forest land area by forest type and owner and stand 

size; tables 6, 7, and 9 display timberland area by forest type 

and owner, age, and stand size, respectively. 

Timberland Stand Age

Stand age classes are fairly evenly distributed on timberland 

across the state as a whole. However, age distributions in 

western and eastern Oregon are quite different, with younger stands (0–60 years) predominant in western Oregon and 

older stands (80–199 years) predominant in eastern Oregon 

(fig. 7). Appendix tables 7 and 8 display timberland area 

by stand age and forest type, and by stand age and owner, 

respectively.

Timberland Stand Size

Statewide, the majority (71 percent) of timberland is in 

the small and large sawtimber classes (average stand diameter at breast height [d.b.h.] 9– 21 inches and greater than 

21 inches, respectively) (fig. 8). Nonfederal timberland tends 

to be skewed to the small size classes and federal timberland to the larger size classes (Azuma et al. 2004a, 2004b) 

(fig. 9). Small sawtimber stands account for 62 percent of all 

sawtimber stands in western Oregon and 82 percent of sawtimber stands in eastern Oregon. Appendix tables 9 and 10 

display timberland area by stand size class and forest type, 

and by stand size class and owner, respectively.

Timberland Productivity

Potential productivity of forest land can be expressed as productivity site classes (app. table 11; figs. 10 and 11). Federal 

timberland has the greatest percentage of acres in lower site 

classes statewide. In western Oregon, state timberland has 

91 percent in the higher classes (>120 cubic feet per acre 

per year) and private timberland has 75 percent. In eastern 

Oregon, most acres are in the lower productivity classes 

(<120 cubic feet per acre per year).

Timberland Volume

Volume of poletimber (5–9 inches d.b.h. for softwoods and 

11 inches d.b.h. for hardwoods) and sawtimber (over 9 inches 

d.b.h. for softwoods and 11 inches d.b.h. for hardwoods) 

across all owners, statewide, and excluding cull volume, is 

over 77 billion cubic feet (fig. 12). Ninety-one percent of this 

volume is from softwoods and 9 percent from hardwoods. 

Cull volume is about 3 billion cubic feet. Appendix table 12 

displays timber volume by timber class (sound or cull), tree 

size class, and species group, and table 13 displays timber 

volume by forest type and stand size class.

The majority of growing-stock volume on Oregon’s 

timberlands is on national forests (52 percent), followed by 

forest industry (19 percent), BLM (13 percent), other private 

forest land (10 percent), and other public land (6 percent) 

(fig. 13). Appendix table 14 displays timberland growingstock volume by owner and species group.

Timberland Growth, Mortality, and Removals

From the 1980s to the 1990s, growth exceeded mortality 

for all owners across all forest types, statewide, resulting in 

positive net growth for growing-stock trees (app. table 15). 

A few forest types, such as mountain and western hemlock, in eastern Oregon on some ownerships showed greater 

mortality than growth. For sawtimber, when removals are 

factored in, the volume of growth is greater than the volume 

of mortality plus harvest removals for public owners but not 

for private owners statewide (app. table 16, fig. 14). This is 

reflected in the ratio of current gross annual growth to the

sum of average annual mortality and average annual removals where values less than 1.0 indicate that mortality and 

removals exceed growth (fig. 15).

The production of timber has shifted away from federal 

land to state and privately owned land over the last three 

decades (fig. 16, app. table 17). In the 1980s, federal land 

in western Oregon had an annual average harvest of 2,667 

million board feet. In the 1990s that number dropped to 

685 million board feet per year. Other public and private 

land averaged 3,046 million board feet per year in the 1980s 

and decreased 8 percent to 2,807 million board feet in the 

1990s. The 74-percent reduction from federal land does not 

represent a change in land class, but is evidence of changing availability of land for timber production based on new 

management decisions. Federal land areas with reduced 

availability include, but are not limited to, riparian reserves, 

wildlife reserves, and access-limited areas. 

In eastern Oregon, from 1980 to 1989, timber harvest 

volume from federal land averaged 1,205 million board 

feet per year. That number dropped to 530 million per year

between 1990 and 1999, a decrease of 56 percent from the

percent of the timberland in eastern Oregon, produced on 

average, 33 percent of the harvest volume per year in the 

1980s (604 million board feet), and 56 percent from 1990 to

defined as those reserved through statute, ordinance, or administrative order; and the Oregon Department of Forestry 

(ODF) classification (Herstrom et al. 2003), which classifies 

forest land into reserved, multiresource (with restricted timber harvest), and active categories (see app. 1 for a description of these categories; see also tables 19 and 20).

In addition to land officially designated as reserved, 

another 12 percent of the forest land in Oregon is currently 

not available for timber harvest (Herstrom et al. 2003). This 

land includes state and county parks, Nature Conservancy 

land, and a number of categories on national forests such

as late-successional reserves, riparian areas, and research 

natural areas. Current regulations allow some timber harvesting on additional land (42 percent of forest land) but 

also include restrictions for wildlife habitat or other uses 

(Herstrom et al. 2003). Revisions of national forest plans, 

state laws, and other agency policies could result in changes 

in timber production locations and acres. 

All of the reserved and multiresource area is managed 

by the Forest Service and other public entities (table 19). Site 

productivity tends to be higher on active forest land, with 

25 percent in site classes of 165 or more cubic feet per acre 

per year compared to reserved and multiresource forest land 

with only 10 percent in the classes of 165 or more cubic feet 

per acre per year (app. table 18).

Inventory Procedures 

Oregon was inventoried by using double sampling for 

stratification (Cochran 1977) for the nonfederal lands and 

a simple stratified random sample for NFS and BLM lands. 

The sampling was implemented on a permanent systematic 

grid producing an even geographic distribution of secondary 

(field) plots across the state. The primary sample used on the 

nonfederal lands consists of photo plots placed at random 

inside each square of the grid.

The primary sample for nonfederal lands was a grid 

of nearly 70,000 points established in 1987 by using aerial 

photography from 1982 with some updates from 1994 for 

eastern Oregon and 24,000 points established in 1994 for 

western Oregon. Data collected on each point included, but

were not limited to, land use, owner, plant community, and 

stage of development. For coniferous stands, percentage of 

crown cover and a height code also were collected. The primary sample is used for the stratification of the secondary 

sample points to increase the precision of estimates.

The secondary sample consisted of 4,378 forest and 

nonforest field locations established in previous inventories 

and remeasured or reclassified in the 1998–99 period for 

eastern Oregon and 1,478 forest and nonforest field locations established in previous inventories and remeasured or 

reclassified in the 1994–98 period for western Oregon. This 

sample represents about a 1-in-16 subsample of the primary 

sample. The national forest plots were taken on a similar 

grid system with a different plot design (Max et al. 1996). 

The data were collected for these inventories between 1993 

and 1996 and are in the 1997 Resources Planning Act (RPA) 

database.

The 1998 eastern Oregon PNW-FIA inventory also 

included reserved lands, which were excluded from previous 

PNW-FIA inventories. The major addition is from Crater 

Lake National Park with about 220,000 acres.

In the previous PNW-FIA inventories in the 1980s, a 

cluster of five subplots covering an area of about 8 acres 

was installed at timberland grid locations. At that time, the 

cluster of subplots sampled a single homogeneous condition, by moving subplots into the condition if necessary. At 

each subplot, variable-radius sampling was used to select 

trees over 5 inches d.b.h., and a fixed-radius plot was used to 

sample seedlings and saplings.

In the 1990s PNW-FIA inventories, the sampling design 

was modified to remove potential bias inherent in the 1980s 

procedures. The term “condition class” was defined for the 

modified design to identify different situations that could 

occur on a plot. A condition class, or “condition,” refers to 

an area with a distinct land class (timberland, woodland, 

nonforest, etc.) and vegetative condition (forest type, stand 

age, etc.). The modified design requires that all subplots 

for a cluster (the plot) remain fixed. For plots that straddle 

two or more conditions, we now sample all conditions by 

mapping the boundaries around each condition, essentially 

subdividing the plot. The information pertinent to each 

condition was recorded as condition class attributes. When 

multiple conditions exist on a plot, all data in one condition 

are processed together. This can affect the amount of information available for classifying stand characteristics, such 

as forest type, stand size, and stand age. For example, on 

7,014 secondary sample locations outside of national forest 

land in the 1990s Oregon PNW-FIA inventory, 7,524 condition classes were sampled, of which 1,951 were timberland 

conditions. On the 1,637 plots that contained a timberland 

condition, roads were the most common nonforest condition 

followed by grassland steppe or high desert shrub land.

Small differences in acreage and volume estimates in 

different publications summarizing data from these inventories (Oregon 1990s periodic inventories) are due to use of 

different versions of the inventory database. The tables in 

this report are compiled from the PNW-FIA integrated database version 1.4 (2004).

Land and Water Area Updated

The Bureau of the Census compiles and publishes the area 

of land and water in the United States every 10 years. These 

area figures, available by state and county, are accepted 

and used by PNW-FIA in Portland as the gross number 

of acres to be inventoried in each county. The previous 

inventory was based on 1980 census data, and the current 

inventory uses 1990 census figures. Raster-scanned U.S. 

Geological Survey topographic maps and a geographic information system are now used by the Bureau of the Census 

to identify water bodies and landforms and to determine the 

size of areas much smaller than was possible previously. As 

a result, the definition of inland water was changed to reflect 

the finer resolution: streams with a minimum width of 200 

feet are now recognized, compared to 660 feet in 1980, and 

small water bodies are now at least 4.5 acres, compared to 

40 acres in the past.

Changes in Ownership Definitions

Land owned by Native Americans is now classified as “other 

private.” In the 1980s inventories, these lands were defined 

as “other public.” Forest industry is no longer divided into 

two categories: “forest industry with mills” or “forest industry without mills;” instead both are now classed as forest 

industry.

Reliability of Inventory Data

Inventories are designed to provide sampling errors consistent with national standards set by the USDA Forest Service. 

The target sampling errors for total timberland area is 3 percent for one million acres and 10 percent for one billion cubic feet of growing-stock volume. The sample design for this 

inventory provides the highest precision when estimates are 

aggregated for the entire state. As the sample is divided into 

smaller units, the confidence intervals (standard errors) increase as a proportion of the estimate. Confidence intervals 

are quantitative expressions of the variability inherent in the 

sampling and estimation procedures. Most of the tables in 

this report show standard errors for the major categories of 

displayed data.

Glossary

available other forest land—Forest land available for harvest but incapable of growing 20 cubic feet per acre per year 

(mean annual increment at culmination in fully stocked, 

natural stands) of industrial wood because of adverse conditions such as sterile soils, dry climate, poor drainage, subalpine sites, steepness, or rockiness.

condition class—A mapped area on a plot with a distinct 

land class (e.g., timberland, oak woodland, nonforest) or a 

distinct vegetative condition (e.g., forest type, stand size). 

The condition identified at plot center is the only condition that is remeasured and used for the analysis of periodic 

change.

cull trees—Live trees of noncommercial species, and live 

trees of commercial species that are more than 75 percent 

defective. Noncommercial species are junipers, Pacific yew, 

Pacific dogwood, apple, and willow. Cull trees are not growing-stock trees.

cull trees, rotten—Cull trees with defect caused primarily 

by rot.

cull trees, sound—Trees of noncommercial species or cull 

trees of commercial species with defect caused primarily by 

poor form and roughness.

diameter class—A classification of trees based on diameter 

outside the bark measured at breast height, 41⁄2 feet above 

the ground. The common abbreviation for diameter at breast 

height is d.b.h. Trees are grouped into 2-inch classes up 

to 21 inches d.b.h., after which the class intervals become 

broader.

forest industry land—Land owned by companies that grow 

timber for industrial use. Includes companies both with and 

without wood processing plants.

forest land—Land at least 10 percent stocked with live 

trees, or land that had this minimum tree stocking in the 

past; is not currently developed for nonforest use; and is 

larger than one acre and at least 120 feet wide. 

forest types—Stands are classified as pure softwood, pure 

hardwood, softwood-hardwood mix, or hardwood-softwood 

mix. Stands with 70 percent or more of the stocking in live 

softwood trees are classified as pure softwood types and 

are assigned the type name of the softwood species with the 

greatest stocking among all softwoods on the condition class 

plot. Stands with 70 percent or more of the stocking in live 

hardwood trees are classified as pure hardwood types and 

are assigned the type name of the hardwood species with 

the greatest stocking among all hardwoods on the condition class plot. Mixed species types are assigned if softwood

stocking is from 31 to 69 percent total stocking on the plot: 

stands with 50 to 69 percent of the stocking in live softwood 

trees are classed as softwood-hardwood types and receive 

a type name that includes the softwood species with the 

greatest softwood stocking followed by the hardwood species with the greatest hardwood stocking; stands with 51 to 

69 percent of the stocking in live hardwood trees are classed 

as hardwood-softwood types and receive a type name that 

includes the hardwood species with the greatest hardwood 

stocking followed by the softwood species with the greatest softwood stocking. For ease in reporting, the secondary 

forest type will be identified after a slash as “softwood” or 

“hardwood” in the summary tables.

growing-stock growth, current net annual—The increase 

in growing-stock volume on timberland during the last year 

of the period between the previous and current inventories. 

Components of current net annual growth for growing-stock 

volume include (a) the increment in net volume of poletimber

Resource Bulletin PNW-RB-242

and sawtimber growing-stock trees alive at the beginning 

of the year and surviving to year end; plus (b) ingrowth, the 

net volume of growing-stock trees reaching poletimber or 

sawtimber size during the year; minus (c) mortality, the net 

volume of poletimber and sawtimber growing-stock trees 

that died during the year.

growing-stock growth, periodic gross—The increase in 

growing-stock volume between the previous and current inventories that is attributable to increasing tree size. Periodic 

gross growth includes (a) the increment in net volume of 

poletimber and sawtimber growing-stock trees alive at both 

the previous and current inventories; (b) the increment in 

net volume of poletimber and sawtimber growing-stock 

trees alive at the previous inventory and harvested between 

inventories; and (c) ingrowth, the net volume of growingstock trees reaching poletimber or sawtimber size between 

inventories.

growing-stock mortality, average annual—The annual net 

volume of poletimber and sawtimber growing-stock trees 

that died between the previous and current inventories.

“cull trees”).

growing-stock volume—Net volume in cubic feet of live 

sawtimber and poletimber growing-stock trees from the top 

of a stump 12 inches tall to a minimum 4-inch top (of central stem) inside the bark. Net volume is gross volume less 

deductions for rot and missing bole sections.

Census (U.S. Department of Commerce 1990). Total land 

area includes dry land and land temporarily or partially 

covered by water, such as marshes, swamps, and river flood 

plains; streams, sloughs, and canals less than 200 feet wide; 

and lakes, reservoirs, and ponds smaller than 4.5 acres.

land class—A classification of land by major use. The minimum area for classification is 1 acre.

mean annual increment (MAI) at culmination—A measure of the productivity of forest land expressed as the average increase in timber volume (in cubic feet) per acre per

on the age at which the MAI culminates for fully stocked 

natural stands. The MAI is based on the site index of the 

plot.

national forest land—Federal land that has been designated by Executive order or statute as national forest or 

purchase units and other lands under the administration of 

the USDA Forest Service, including experimental areas and 

Bankhead-Jones Title III land.

net volume—Gross volume less deductions for sound and 

rotten defects. Growing-stock net volume is gross volume 

(in cubic feet) less deductions for rot and missing bole 

sections on poletimber and sawtimber growing-stock trees. 

Sawtimber net volume is gross volume (in board feet) less 

deductions for rot, sweep, crook, missing bole sections, 

and other defects that affect the use of sawtimber trees for 

lumber.

noncommercial species—A tree species not commonly 

used for industrial wood products: juniper, Pacific yew, 

Pacific dogwood, apple, and willow. Noncommercial species 

will not be included in growing-stock volume tables; however, if one or more of these species dominate on a plot, the 

forest type might be classified as a noncommercial species.

nonforest land—Land that has never supported forests or 

formerly was forested and currently is developed for nonforest uses. Included are lands used for agricultural crops, 

Christmas tree farms, cottonwood plantations, improved 

pasture, residential areas, city parks, constructed roads, operating railroads and their right-of-way clearings, powerline 

and pipeline clearings, streams more than 30 feet wide, and 

1- to 40-acre areas of water classified by the USDC Bureau 

of the Census as land. If intermingled in forest areas, unimproved roads and other nonforest strips must be more than 
13

Timber Resource Statistics for Oregon

120 feet wide, and clearings or other areas must be 1 acre or 

larger to qualify as nonforest land.

nonstocked area—Timberland less than 10 percent stocked 

with live trees. Recent clearcuts scheduled for planting are 

classified as nonstocked area.

other private land—Private land not owned by forest 

industry. Native American land, farmer-owned land, and 

miscellaneous private land are included.

other public land—Land administered by public agencies other than the USDA Forest Service and USDI Bureau 

of Land Management. Other public land does not include 

Native American land, which is included with other private 

land.

poletimber stands—Stands with a quadratic mean diameter (mean diameter weighted by basal area) from 5.0 to 9.0 

inches at breast height if a softwood stand and from 5.0 to 

11.0 inches at breast height if a hardwood stand.

poletimber trees—Live growing-stock trees of commercial 

species that are 5.0 inches in d.b.h. or larger but smaller than 

sawtimber trees.

reserved other forest—Forest land that is incapable of 

growing 20 cubic feet per acre per year (mean annual increment at culmination in fully stocked, natural stands) of industrial wood and has been dedicated to noncommodity use 

through statute, ordinance, or administrative order.

reserved timberland—Forest land that is capable of growing 20 cubic feet or more per acre per year (mean annual 

increment at culmination in fully stocked, natural stands) 

of industrial wood but has been dedicated to noncommodity 

use through statute, ordinance, or administrative order.

sapling and seedling stands—Stands with a quadratic 

mean diameter (mean diameter weighted by basal area) less 

than 5.0 inches at breast height.

sapling and seedling trees—Live trees of commercial species that are less than 5.0 inches in d.b.h. with a minimum 

height of 6.0 inches and that have no diseases, defects, or deformities likely to prevent their becoming poletimber trees. 

Saplings have a minimum diameter of 1.0 inch.

sawtimber stands—Stands with a quadratic mean diameter 

(mean diameter weighted by basal area) 9.0 inches and 

larger at breast height if a softwood stand and 11.0 inches 

and larger at breast height if a hardwood stand. Small sawtimber stands are sawtimber stands with a mean diameter 

(weighted by basal area) less than 21.0 inches at breast 

height. Large sawtimber stands are sawtimber stands that 

have a mean diameter 21.0 inches or larger at breast height. 

Different utilization standards (such as 7.0-inch diameter) 

would result in higher stand volumes.

sawtimber trees—Live softwood trees of commercial species at least 9.0 inches in d.b.h. and live hardwood trees of 

commercial species at least 11.0 inches in d.b.h. At least 25 

percent of the board-foot volume in a sawtimber tree must 

be free from defect. Softwood trees must contain at least one 

12-foot saw log with a top diameter of not less than 7 inches 

outside bark; hardwood trees must contain at least one 

8-foot saw log with a top diameter of not less than 9 inches 

outside bark.

sawtimber volume—Net volume of sawtimber trees measured in board feet. Softwood volume is estimated from the 

top of a stump 12 inches tall up to a minimum 6-inch top 

diameter, inside bark, and hardwood volume is estimated 

from the top of a stump 12 inches tall up to a minimum 8-

inch top diameter, inside bark. Net sawtimber volume equals 

gross volume less deduction for rot, sweep, crook, and other 

defects that affect use for lumber.

Scribner rule—The common board-foot log rule used locally to determine sawtimber volume. Scribner volume is 

estimated in terms of 32-foot logs in western Oregon and 

16-foot logs in eastern Oregon for softwoods and hardwoods. See “sawtimber volume” for utilization limits.

site class—A classification of the potential productivity of 

forest land expressed as mean annual increment (MAI) of 

timber volume (in cubic feet) at culmination in fully stocked 

natural stands. Six classes in this report are based on a range 

of MAI values that were calculated on every plot.

site index—A measure of the productivity of forest land 

expressed as the average height of dominant and codominant 

trees at a specified age.
14

stand.

stand-size class—A classification of stands based on tree 

size. Stand-size classes are sawtimber, poletimber, and sapling-seedling stands.

state land—Land owned by states or administered by state 

agencies.

stocking—The degree of occupancy of land by trees, measured by basal area or number of trees by size and spacing, or 

both, compared to a stocking standard; that is, the basal area 

or number of trees, or both, required to fully use the growth 

potential of the land.

timber class—A classification of trees as growing stock, 

cull, and salvable dead. Growing-stock trees are divided into 

poletimber and sawtimber trees.

timber harvest—Volume of roundwood removed from forest land for products.

timber volume—Includes the net volume in cubic feet of 

poletimber and sawtimber trees and salvable dead sawtimber trees, and the net volume in cubic feet of cull trees of 

commercial species. Volume is measured from the top of 

a stump 12 inches tall to a minimum 4-inch top diameter, 

inside bark.

timberland—Forest land capable of growing 20 cubic feet 

or more per acre per year (mean annual increment at culmination in fully stocked, natural stands) of industrial wood; 

is not in a reserved status through removal of the area from 

timber use by statute, ordinance, or administrative order; is 

not in a withdrawn status where it is pending consideration

Appendix 1—Oregon Department of 

Forestry—Forest Land Management 

Classifications (from Herstrom et al. 2003)

1. Nonforest—land with <10 percent crown closure 

that has not previously been in forest use and has 

not been converted from forest to another use 

(Note: recent timber harvest units are forest land).

2. Reserved forest (Forest reserved for conservation and recreation)—includes land reserved 

from regularly scheduled timber harvest by law, 

regulation, or forest plan requirement. The primary purpose of the designation is to reserve the 

land for production of nontimber values. Forest 

management is used to produce wildlife, esthetic, 

or other values, and limited harvests may only be 

conducted when it will benefit those values (i.e., 

safety, maintaining wildlife habitat, etc.).

 The reserved forest class includes administratively withdrawn areas, congressionally reserved 

areas (such as national monuments, national 

parks, national wildlife refuges, Steens Mountain 

Cooperative Management and Protection Area, 

wild and scenic areas, wild and scenic rivers, and 

wilderness areas), late-successional reserves, state 

and county parks, riparian reserves (federal), special areas (such as areas of critical environmental 

concern, botanical areas, ecological emphasis 

areas, outstanding natural areas, and research 

natural areas), The Nature Conservancy land, and 

wildlife areas.

3. Multiresource forest (forest with restricted 

timber management)—includes land where restrictions on timber harvesting have been implemented through forest plans, state laws, or agency 

policies. This includes portions of land within 

management allocations where scheduled timber 

harvest may occur, but where restrictions for wildlife habitat or other uses will significantly reduce 

timber outputs.

4. Active forest (actively managed for timber production)—includes lands where scheduled timber 

harvest may occur and where sustainable supplies 

of timber are anticipated. These forest lands are 

regulated through the Oregon land use planning laws to maintain the land in forest uses by 

restricting development and through the Oregon 

Forest Practices Act to protect soil, air, water, and 

wildlife resources by regulating commercial forest 

operations. The active forest class includes private 

land and other public land.

Federal Lands—Reserved and 

Multiresource (Restricted Timber 

Management) Categories

Adaptive management areas—landscape units designated 

to encourage the development and testing of innovative approaches to restoring and managing late-successional and 

old-growth forests.

Administratively withdrawn areas—land identified in forest or district plans that includes recreation and visual areas, 

back country, and other areas where management emphasis 

precludes scheduled timber harvests.

Congressionally reserved areas—normally preclude timber harvesting except where it is needed to preserve or enhance the values of the designations, which include national 

monuments, national parks, national wildlife refuges, Steens 

Mountain Cooperative Management and Protection Area, 

wild and scenic areas, wild and scenic rivers, and wilderness 

areas.

East-side “screens”—the interim management direction for 

east-side federal forests (i.e., late-successional and wildlife 

“screens”) designed to maintain future planning options 

concerning wildlife habitat associated with late and old 

structural stages, fish habitat, and old-forest abundance. The 

screens allow for some timber harvest, limited to thinnings 

or group or individual tree selection, in stands where 

old-forest conditions, either multistrata with large trees or 

single-stratum with large trees, are at or above historical 

range of variability and timber harvest is needed to maintain 

or enhance old-forest conditions.
19

Timber Resource Statistics for Oregon

Experimental forests—used predominantly for research 

on the management of watersheds, soils, and vegetation. In 

general, the forests are used to develop concepts and tools 

needed to predict effects of disturbance, land use, and climate change on ecosystem structure, function, and species.

Key watersheds—part of the aquatic strategy within the 

federal Northwest Forest Plan. The major focus of management within the watersheds is on maintenance and restoration of fish habitat. The land use designation is an overlay 

on all other allocations within the plan. It requires that no 

new roads be built within unroaded portions of the watersheds, that existing road system mileage be reduced, and 

that no timber harvesting be conducted without a watershed 

analysis.

Late-successional reserves—areas that have been designated in federal plans to protect and enhance conditions of latesuccessional and old-growth forest ecosystems. They are 

designed to serve as habitat for species that use these forests, 

such as the spotted owl. There is no timber harvest allowed 

in stands over 80 years of age. Thinning and other silvicultural activities are restricted to treatments that are beneficial 

to the creation of late-successional forest conditions.

Matrix land (federal)—federal land in western Oregon outside the other federally designated categories (congressionally reserved, late-successional reserves, adaptive management areas, administratively withdrawn, and riparian 

reserves). Most federal timber harvesting and other silvicultural activities will be conducted in the matrix subject 

to standards and guidelines that include protective buffers around certain wildlife habitats (e.g., spotted owl and 

marbled murrelet sites) and leave snags and green trees in 

harvest units. Green tree retention requirements include:

• In the Oregon Coast Range each 640-acre block 

is managed on a 150-year rotation. When an area 

within a block is cut, 12 to 18 green trees per acre 

(t.p.a.) are retained (16 to 25 t.p.a. on BLM lands 

south of Grants Pass). There must be 25 to 30 

percent of each block in late-successional forest at 

any point in time.

• For all other lands in western Oregon at least 15 

percent of the area associated with each cutting 

unit is retained with a goal of having 70 percent of 

the total leave area in aggregates of 0.2 to 1 hectare 

or more.

National grassland—the Crooked River National Grassland 

is managed to promote the development of grassland agriculture and sustained yield management of forage, fish, 

wildlife, timber, water, and recreation resources. Fuelwood 

cutting is allowed by permit only in juniper stands that are 

not designated as old growth.

National recreation areas—Vegetation is managed to promote the maintenance and restoration of native plant communities. Trees are cut only to meet nontimber management 

objectives including recreation and wildlife habitat maintenance.

National scenic area (Columbia Gorge)—protects and 

provides for the enhancement of the scenic, cultural, recreational, and natural resources of the Columbia River Gorge.

Riparian reserves (federal lands)—areas adjacent to both 

sides of a stream, lake, or wetland where timber harvesting 

is prohibited. The width of the reserves are as follows:

• Fish-bearing streams, lakes, and natural ponds—a 

distance equal to two site-potential trees or 300 

feet (each side), whichever is greater.

• Permanently flowing non-fish-bearing streams, 

constructed ponds and reservoirs, and wetlands 

larger than 1 acre—a distance equal to one sitepotential tree or 150 feet (each side), whichever is 

greater.

• Seasonally flowing or intermittent streams—a 

distance equal to 100 feet (each side).

Special areas (includes areas of critical environmental

concern, botanical areas, ecological emphasis areas, 

outstanding natural areas, and research natural areas)—

special area designation protects and provides interpretation 

of unique geological, biological, and cultural areas for education, scientific pursuits, and public enjoyment. These areas 

preserve, protect, or restore native species composition and 

ecological processes of biological communities. They are 
20

Resource Bulletin PNW-RB-242

available for short- or long-term scientific study, research, 

and education and serve as a baseline against which human 

impacts on natural systems can be measured. Uses are managed to prevent loss of outstanding values.

Private and Other Public Land—

Multiresource (Restricted Timber 

Management) Categories

Habitat conservation plans—Nonfederal landowners who 

wish to conduct activities on their land that might incidentally harm (or “take”) a species listed as threatened or endangered must first obtain an incidental take permit from the 

U.S. Fish and Wildlife Service. To obtain a permit, the applicant must develop a habitat conservation plan designed to 

offset any harmful effects the proposed activity might have 

on the species.

Oregon scenic waterways program—The Oregon Parks 

and Recreation Department must be notified of certain 

activities (including cutting trees) proposed within 1⁄4 mile 

of the bank of Oregon’s designated scenic waterways. The 

proposed uses or activities may not be started until the written notification is approved, or until 1 year after the notice is 

accepted. Within that period, the Parks Department employs 

a variety of tools to maintain the scenic value of the river.

Riparian management areas (RMA)—areas on private 

and state lands in eastern Oregon adjacent to both sides of 

a stream or lake where timber harvesting is restricted. In 

general, coniferous trees in amounts similar to mature forests must be retained in riparian management areas along 

streams. The width of the riparian management area differs 

depending on the size of the stream and whether fish are 

present or the stream is used as a domestic water supply. 

Riparian management area widths for streams are generally 

as follows:

• Large streams (about 24 or more feet wide) with 

fish—100 feet

• Medium streams (about 5 to 24 feet wide) with 

fish—70 feet

• Small streams (up to about 5 feet wide) with 

fish—50 feet

• Small streams with domestic water use—20 feet

• Small streams without fish or domestic water 

use—no retention

Timber harvesting is restricted along streams on state forests 

in northwest Oregon generally as follows:

• Large and medium streams, and small streams 

with fish—170 feet

• Small perennial streams without fish—170 feet

• Small intermittent streams—100 feet.

Timber harvesting is restricted near streams on the Elliott 

State Forest in southwest Oregon generally as follows:

• Perennial streams with fish—100 feet

• Intermittent streams with fish—75 feet

• Perennial streams without fish—50 feet

Significant wetlands—In wetlands and estuaries larger than 

8 acres, half of the trees, by species, in each size class must 

be left after harvesting. These trees must include trees that 

border the wetland, contribute to bank stability, or are used 

by predatory birds for nesting and perching.

State forest plan restrictions—State forests in different 

regions have different harvest restrictions including:

• Northwest Oregon State Forests Management Plan 

is based on an approach called structure-based 

management. Structure-based management is designed to produce and maintain an array of forest 

stand structures across the landscape in a functional arrangement that provides timber revenue, 

habitat for native species, and healthy aquatic systems. Structure-based management goals include 

maintaining a proportion of the forest in a mix of 

stand types over time: 5 to 15 percent in regeneration types (i.e., seedlings, saplings, and herbs and 

shrubs), 10 to 20 percent in closed single-canopy 

types, 15 to 35 percent in understory reinitiation 

types (i.e., gap in tree canopy allows understory 

of shrubs and herbs), 20 to 30 percent in layered 

types (i.e., tree canopy of two or more layers with 

trees of 18 inches d.b.h.), and older forest types 

(i.e., a minimum of eight trees per acre at least 32 

inches d.b.h. and multiple canopy layers).
21

Timber Resource Statistics for Oregon

• Elliott State Forest Habitat Conservation Plan 

uses a landscape approach to provide and maintain habitat for the northern spotted owl and the 

marbled murrelet. The forest is divided into 17 

management basins that use a mix of 80- to 240-

year rotations. Over time, from 13 to 66 percent of 

each management basin will be managed as nesting, roosting, and foraging habitat. In addition, 19 

percent of the forest is designated as reserves.

• Eastern Oregon region. Selective harvesting is 

used in most of the eastern Oregon region’s forests 

to maintain or improve uneven-aged stand structure. Even-age management is limited to stands 

where ecological conditions, insects, or diseases 

make selective harvesting less attractive.

State and county parks (includes state parks, state park 

land, city and county parks, and waysides)—Goals for 

Oregon state parks include having existing and future recreational uses coexist and complement natural, scenic, and cultural resources within the park. State parks are assessed to 

identify discrete areas and determine the levels of suitability 

of resource areas for recreational use in conjunction with the 

need to protect important resources from disturbance. These 

resources include vegetation, wildlife habitat, protected species, water features and hazards, wetlands, and historical 

resources. Each of these resources is classified with respect 

to resource suitability based on criteria including current 

resource conditions, types, sensitivity, rareness, and extent 

of existing development or other intrusions. Areas with resources that are very sensitive or rare, even though they may 

be in good condition, have a very low tolerance for intensive, public, recreational uses and facilities development and 

typically are assigned a low suitability level for recreational 

development.

State research forests—The forests are used predominantly 

for teaching and research. They provide an array of education and research opportunities to advance societal awareness and participation in sound forest stewardship while 

providing sustainable financial resources to meet these 

needs. Forests are used for a variety of teaching and research 

projects that include studies in silviculture, engineering, 

ecology, recreation, wildlife, cultural resources, and other 

subjects.

The Nature Conservancy land—The Nature Conservancy’s 

mission is to preserve the plants, animals, and natural communities that represent the diversity of life on Earth by protecting the land and water they need to survive. The Nature 

Conservancy’s vision is to conserve a set of places that, if 

managed appropriately, will ensure the long-term survival of 

all their native life and natural communities.

State wildlife areas (game management areas, game reserves, wildlife areas, and osprey management areas)—

The State Wildlife Commission’s goals are to:

• Maintain all species of wildlife at optimum levels.

• Develop and manage the land and water in a manner that will enhance the production and public 

enjoyment of wildlife.

Land is managed to prevent serious depletion of any 

indigenous species and to provide the optimum recreational 

and aesthetic benefits. Management practices affecting forage removal are established to protect the property and benefit wildlife resources.
