Executive Summary The present study assessed the hardwood resources in western Washington for 2010 and out to 2030.
The study is a continuation and update of hardwood resource assessments for western Washington
begun in the 1990s. The project used the Washington State Biomass Assessment database to map the
volume of hardwoods by management zone, owner group, diameter class and species. Volume
estimates were derived by first identifying the number of unreserved acres capable of active forest
management and commercial harvesting, then determining the number of acres removed from timber
production including areas in upland and riparian zones.
About 4 million acres exist in western Washington that were not in either buffer zones, small private,
federal or other public ownerships. Acres in the small private owner class, which include ownerships
with holdings of greater than 10 acres and not in buffer zones were substantial, e.g., they represented
an additional 1.2 million acres. There were 1.3 million, 0.7 million and 0.1 million acres in core, inner
and outer buffer zones respectively across all owner classes. Large private industry and tribal owner
groups had 0.54 million acres restricted by core buffer riparian regulations and were unavailable for
commercial harvests. Approximately 0.67 million acres in riparian buffer areas in large private and state
owner classes allowed for some commercial harvesting activity. Small private land owners had about
equal number of acres, 0.1 million, in the core buffer areas with no commercial activity allowed, and in
the inner and outer areas, where some commercial activity was allowed. Federal and other public
ownership acres totaled 1.8 million, about 0.76 million of them in buffer areas. An additional 30
thousand acres were located in wetland buffers across all owner classes.
A significant amount, about one-third, of the 19.8 billion board feet of hardwood volume inventory that
is located on 8.3 million acres across all owners and include upland and riparian areas in 2010 was
unavailable. The hardwood volume level on acres that allowed unrestricted commercial harvesting sits
at 6.3 billion board feet. These acres were not in buffer zones, or small private, federal or other public
ownerships. The acres included large private, state and tribal ownership. Unrestricted volume on small
private land owner acres was calculated to be an additional 5.3 billion board feet. Small private owners
represented the largest volume of unrestricted volume among all owner groups. Hardwood inventory
that was restricted from commercial harvest activity due to buffer regulations amounted to 6.7 billion
board feet, of which 3.6 billion was located on core buffer areas completely restricted from commercial
harvesting. The majority of the 3.2 billion board feet in buffer areas that allowed some commercial
harvesting, i.e., 1.9 billion, was located on WA DNR lands.
Approximately 8.3 billion board feet of hardwood standing timber was of commercial size and available
for harvests in 2010. This volume included all owners and volumes in riparian buffers that allowed some
management as well as upland acres. About 4 billion board feet were under active management and
unrestricted commercial harvesting by large private and state owners. An additional 3.3 billion board
feet were found on upland, small private lands. Over two thirds of the hardwood volume available for
harvest was Red Alder. Seventy-five percent of the volume in large private ownerships was alder, with
20% maple. Fifty-four percent of small private volume was alder with 37% maple. Sixty percent of the
hardwood volume available for harvest was found between 10 and 20 inches in diameter. Two thirds of
the 10 and 20 inch diameter trees were alder.

Introduction Hardwood tree species grown in the Pacific Northwest comprise an important economic component of
the timber resource for the forest products industry in western Washington. Hardwood species are
intermixed with softwood species and represent potential value-added when a harvest activity occurs.
In recent years, hardwood consumption by mills amounted to over 5% of the total log volume consumed
in the state (WA DNR, 2012). The potential for the economic contribution of a timber harvest to
increase further exists as mills continue to utilize this hardwood component and convert it into forest
products. This, in turn increases financial returns to forest landowners and operators. Knowledge of the
existence and condition of the hardwood inventory is necessary to realize these added returns.
There have been four previous studies of the hardwood resource in western Washington undertaken by
the Washington Hardwoods Commission (WHC). Previous work has shown 1) that stands dominated by
hardwoods or softwoods can be identified using Landsat imagery reasonably well (Marshall and
Associates, Inc.; R.V. Quenet, Ltd., 1996); 2) age classes of hardwood-dominated stands can be
approximated using Landsat’s normalized difference vegetation index or NDVI (Marshall and Associates,
Inc., 1999); 3) there was a substantial amount of hardwood resource located in riparian buffers that are
not available for harvest (Marshall and Associates, Inc., 2000); and 4) there were about 3.7 million acres
of commercially harvestable timberlands in western Washington containing 9 billion board feet of
available hardwood volume (Washington Hardwoods Commission, 2002).
The 2002 study undertaken by the Commission is not directly comparable to this assessment for a
variety of reasons: 1) this study used a Landsat-based inventory stratification product based on the
Gradient Nearest Neighbor methodology (GNN) for inventory which eliminates the need to expand
sampled plots across the study area, 2) the riparian buffer rules were modeled differently to account for
Forest & Fish rules on non-HCP lands, 3) specific management plans and off-base areas for state and
federal lands were used, and 4) the definition of non-operable lands was slightly different. Given the
differences between the two assessments, any interpretation of the results between studies to
determine hardwood trends is not advised.
An accepted perception is that the demand for hardwood fiber is greater than its available supply. It is
also known that various restrictions to harvesting the hardwood resource exist. In addition, there is a
sense that a portion of the hardwood growing stock is not being managed efficiently and that the
hardwood inventory is decreasing as a percent of the total standing inventory as more forest acres are
converted to softwoods.
Given these perceptions, the study team addressed the following questions: a) how much hardwood
growing stock currently exists in Washington State; b) what is the size class structure and location of the
inventory; c) what ownerships currently manage the growing stock; and d) how much volume is under
riparian management regulation.
The study team used the Washington State Biomass Assessment (WSBA) (Perez-Garcia, et al., 2012)
database to address these questions. The database was revisited to estimate the volume of hardwood
timber in Washington State by reexamining the growth and yield modeling assumptions and inventory
data contained in the database to evaluate the hardwood component. There were two study tasks
outlined in the work proposed to the Washington Hardwoods Commission: a) evaluate the database for
its utility in estimating the hardwood growing stock volume in western Washington State; and b)
6 | P a g e
determine the volume of hardwood species available for harvest in 2010, and out to 2030. To do so, the
study team modeled a harvest scenario to calculate the post-harvest inventory volume and project the
growing stock volume in five year increments out to 2030. As the modeling periods are in 5 year
increments from 2010 to 2030 any figures reported here as 2013 (or vice versa) represent annualized
activity and inventory between 2010 and 2014.
The report is organized as follows. The methods section describes the overall project approach. This
section is followed by results presented in the following order. First, acres summarized by various
categories are shown, and is followed by the modeled timber harvest scenario. A description of the
volume available for harvest is then presented proceeded by a concluding section.
Methods The study relied on the inventory and parcel database assembled over the past 15 years, and most
recently used to calculate forest biomass associated with harvest activities. Two steps were required to
validate the inventory data:
a) Revisit the plot data to determine the amount of hardwood inventory in each forest type.
The study team obtained Washington State forest inventory plot data from Oregon State University
(OSU). OSU scientists combined GNN methods with FIA and other plot data to develop an estimate of
the forest inventory across Washington State (described below). These data were used to estimate the
biomass components of trees on Washington plots in the biomass assessment study. While several tree
parameters, including tree species, were used with biomass equations to develop the volume of biomass
by tree component, the biomass reported in the WSBA did not summarize volume by tree species.
Hence the study team revisited the plot data to determine the amount of hardwood volume contained
on each plot and its associated forest type.
b) Evaluate the findings of Task (a) using alternative data sources provided by the Washington
Hardwoods Commission.
The study team conducted a preliminary validation of the data for hardwood species obtained from plot
information by examining past reports produced for the WHC, existing state reports published by WA
DNR and unpublished data collected by WA DOR on harvest activity. The study team concluded that
discrepancies were minor and that the study should proceed using the WABA database to extrapolate
hardwood inventories in western Washington.
Data Forest Inventory data developed by the Landscape Ecology, Modeling, Mapping & Analysis (LEMMA)
group located at OSU were used to develop inventory profiles for Washington State (Ohmann &
Gregory, 2002). The LEMMA project used the GNN method to create large scale, high resolution spatial
maps of vegetation. Complete coverage of Washington State was provided by using multiple modeling
regions form two LEMMA GNN projects: Mapping for Northwest Forest Plan Effectiveness Monitoring
(NWFP) and the Interagency Mapping and Assessment Project (IMAP). The biomass assessment study
team analyzed the spatial information from these two projects, and produced 6,085 unique forest class
plots (FCID), of which 5,998 are forested under GNN classification. The FCID plots were reexamined by
the hardwood assessment study team to determine their feasibility to extrapolate the hardwood
inventory.
7 | P a g e
Growth Modeling Forest plot data were used to simulate future stand inventories using the appropriate Forest Vegetation
Simulator (FVS) variant. The simulations began in 2006, the year GNN imagery was acquired. Three
variants were used to capture the variation in growth and yield found in western Washington. A 2010
baseline was developed using harvest levels from prior years derived from WA DNR harvest reports. The
biomass assessment study team applied a set of alternative silvicultural regimes implemented with FVS
modeling options. A more detailed description of the silvicultural regimes implemented with FVS
models is contained in the Washington State Biomass Assessment report (Perez-Garcia, et al., 2012).
Spatial Analysis The Washington State Forestland Database (Rogers & Cooke, 2009) contains 2009 parcel data, roads,
stream buffers, streams, lakes and wetlands, ownership, slope and elevation. The database also has a
satellite imagery layer. Links exist between the parcel database and the forest inventory and harvest
activity data that describe a unique combination of owner, forest inventory, slope class and
management zone (core, inner and wetland buffers, uplands, reserves, and special management areas)
for 37 million geographic segments.
Each geographic segment has a unique inventory created from the FCID plot from the LEMMA work
described earlier and its associated FVS modeling projection that was specific to that location on the
landscape. The forest inventory was assumed to be managed according to the various combinations of
owner, inventory, slope class, and management zone based on the management alternatives and
silvicultural options described in the WABA report. To allow for harvest and forest operation options
analysis, each geographic segment was associated with all possible harvest and forest operation options
that conformed to the specific management class and zone.
For example, in Figure 1, various segments are depicted in the upper left snapshot. The forest land use
layer is provided in the snapshot in the upper right corner. The management class layer from parcel
information is overlaid in the middle left snapshot. Information on riparian zones is overlaid in the
middle right snapshot. Slope class, used to assign harvest configuration alternatives, is demonstrated in
the lower left picture. Inventory from FCID plot information and the modeling exercise is shown in the
lower left frame. Each segment is treated and the resulting post-harvest volume is calculated.

Harvest Modeling Three harvest regimes were used to project the future condition of the inventory: a) a regime that only
includes a commercial thinning (CT), b) a regime that only includes a final harvest (FH), and c) a regime
that includes a commercial thin and a final harvest occurring in 2025 or 2030 (CT->FH). The allocation of
standing volume to harvest was weighted using a volume per acre priority by parcel. Harvest targets by
owner by county were used to allocate harvestable inventory, and then relaxed to only by owner when
targets were not met. Harvest targets were set as the average of 10 years from 2000 – 2010 which is
2.74 BBF for all species. Hardwoods were not specifically targeted when volume requested to meet a
target level was imposed.

Results
Definitions Open water: lakes and open-water wetlands identified from the Washington DNR hydrology & wetlands
layers that appear forested from the GNN Landsat data. The spatial resolution of Landsat is often too
coarse to capture smaller lakes and wetlands where timber harvest is restricted, hence the use of
ancillary water type data.
Parks & other non-timber forest: National, state and municipal parks, monuments, recreation areas,
wildlife reserves and scenic areas.
Less than 10 forested acres owned: small private parcels where the owner has less than 10 acres of
forestland across all the parcels they own.
Withdrawn areas: Northwest Forest Plan reserves and congressionally withdrawn areas on U S Forest
Service lands, some municipal watersheds (like the Cedar River) and DNR deferred harvest areas.
Timberland Acres
Determination of Available Acres There are approximately 8.3 million acres of commercial timberland acres in western Washington that
are unreserved, with exception of core buffer areas, for forest management (Table 1). There are an
additional 4.8 million acres reserved and unavailable to timber production.

2000 – 2030 Harvest Volumes
Modeled Harvest Volumes by Owner Class Harvest levels were introduced to account for removals when calculating inventories into the future.
Historical annual harvest volumes for all species were used to project future harvest levels (Figure 5 and
Table 5Error! Reference source not found.). An even flow harvest of 2.7 billion board feet/year across
all species was modeled from 2015 to 2030. Nearly two-thirds of this volume was allocated to the large
private ownership by the harvest modeling procedure outlined earlier. Hardwood harvest levels grow to
0.4 billion board feet by 2020 (Figure 6, Table 6). There was no attempt to adjust the hardwood
component of the modeled harvest volumes, as these volumes were used to calculate standing
inventory volumes rather than produce a future hardwood harvest assessment. Rather, the modeled
harvest levels are used to better understand future inventory levels.

harvest allocation procedure targeted all species volumes and not hardwood or softwood separately.
These simulations produced an increase in the alder hardwood volume component between 2010-2030
of 60-80% (Figure 6 and Table 6). The overall hardwood component of the all species harvest volume
increased from 9.4 to 15.0%.

Modeled Harvest Volume by Diameter Class Figure 7 and Table 7 present the diameter breakout for modeled hardwood harvest volumes. The
majority of the modeled harvest volume is in the 10 to 20 inch class, ranging from a low of 58% in 2010,
2020, and 2025 up to 66% by 2030. Growth in the smaller diameter class is evident in the chart and

2010 – 2030 Inventory
2010 Hardwood Inventory by Owner Class & Management Zone In 2010, nearly one third, about 6.3 billion board feet (BBF), of the standing inventory of about 20 BBF) is
found on upland acres under large private, state and tribal ownerships. An additional 5.4 BBF are on
upland, small private lands. However, most of the 19.8 BBF of standing inventory is not available for
harvest. Volume in the core buffers is never available and much of the inventory outside of these buffer
areas is too young or too small for harvest before 2030. Also, since there was no attempt by the study
team to adjust this inventory by calculating the volume that is economically feasible to harvest, the
volume that might actually be harvested and make it to the mill is even smaller.
Across owner classes, the small private ownerships have the most hardwood volume even though they
only represent 17% of the acres (Figure 8 and Table 8). Active management on these lands is less likely
for commercial harvesting, thereby reducing the hardwood inventory estimate considerably.

2010 – 2030 Hardwood Inventory by Owner Class As expected, hardwood inventory levels grow over time given that harvest levels are only a small
percentage of the annual growth (Figure 10 and Table 10). The growth rate observed for large private
lands is above average, and begins to dissipate by 2030. Hardwood inventory growing on large private
lands grows by 74% from 2010 to 2030. Hardwood inventory across all owners increases by 55% over
this time period.

2010 – 2030 Hardwood Inventory by Species Alder comprises nearly two thirds of the inventory in 2010 and increases to 70% by 2030 (Figure 12 and
Table 12). There is 68% more alder volume in 2030 than in 2010. The growth is surpassed only by birch,
which has a much smaller volume base. The growth in cottonwood is relatively small with only a 20%
increase over 2010 levels.

Available for Harvest in 2010 All volumes shown previously are calculated at the stump and not at the mill gate. It is prudent to
subtract at least 10% to account for volume left in the woods or at the roadside due to breakage or
defect when comparing the volume available for harvest with the harvest volume reported at the mill.
Available for Harvest by Management Zone Approximately 8.3 BBF of hardwood standing inventory is available for harvest in 2010 (Figure 14 and
Table 14). Ninety-four percent of this volume is in located the upland management zone and about 4
BBF is under active management with unrestricted commercial harvesting by large private and state
owners. An additional 3.3 billion board feet are found on upland, small private lands.

Available for Harvest by Species Over two thirds of the hardwood volume available for harvest is red alder (Figure 15 and Table 15). It is
interesting to note the difference in alder volume versus other hardwoods between large private and
small private owners. Alder makes up over 75% of the hardwood available for harvest on large private
lands whereas on small private it is only 54% (Table 15). Over one half of the maple component is found
on small private lands.

Conclusion In 2010, there exist about 4.1 BBF of inventory growing on uplands that is available for harvesting by
large private, state and tribal owners in western Washington. An additional 3.3 BBF are found on
upland, small private lands. Modeled hardwood harvest volumes of 0.4 BBF suggests that about 10% of
the large private, state and tribal owners’ volume is being harvested. If the inventory on small private
uplands is factored into the calculation this percentage drops to about 5%. An additional hardwood
volume estimated at 3.6 BBF in western Washington is considered completely restricted from
commercial harvesting activities due to its location within core buffer areas across all owner classes.
WA DNR manages riparian areas that contain 1 BBF on upland acres and 143 MBF on acres in buffers –
both available for harvest in 2010. Large private industry has 75% of its volume in alder with 20 percent
in maple, while small private industry has 54% in alder and 37% in maple. Developing management
options for small private landowners presents an opportunity to expand hardwood management,
particularly on upland acres.
