The Future of Washington’s Forests and Forestry Industries: Practical applications of FIA data April 4, 2007 Bruce Lippke and Ara Erickson Rural Technology Initiative College of Forest Resources University of Washington
2
Today’s Presentation Future of Washington Forests and Forestry Industries study Background Key points Use of FIA data Forest land conversion Timber supply

Future of Washington’s Forests and Forestry Industries Competitive Position Study Land Conversion Study and Cascade Foothills Forestry Viability Timber Supply Study Economic Contribution Study State Granted Lands Return on Investment Study Analyze the competitive position of Washington’s forests products industry Legislature Scope of Work Update the 1992 Timber Supply Study Evaluate the economic contribution of the forest products industry A B C Assess the trends and dynamics that commercial and residential development play in the conversion of the state’s forests to non-forestry uses D Recommend policy changes E Assess the expected rate of return from state granted lands F Analyze and recommend policies and programs to assist Cascade foothills area landowners and communities in developing and implementing innovative approaches to retaining traditional forestry G

Eastside Issues 1.Forest health 2.Increased fire risk 3.Declining timber harvest and processing infrastructure
5
1979-1999 Mortality Rate = 2.2 TPA Latest inventory 2000+ Mortality Rate 8.4 TPA
6
Impact on Fire Hazard of Thinning to BA 45
7
Westside Issues 1.Economic viability is key to sustaining lands in forests and reducing conversions 2.Changing management technology increases income, jobs and even carbon but reduces habitat 3.Many opportunities to improve the environment at low cost are being missed

Washington’s Forest Sector Today During past 15 years the industry was forced to adjust to new harvest levels as result of federal changes, HCPs, ESA and other regulations. Primarily a commodity production business model Produces lumber and newsprint

Timber Supply and FIA Inventory FIA points provide tree list measurements Challenges Location, density, privacy, time Solution Update current state from past inventory and additional data
24
To start… Stratify FIA points Sum acreage Choose representative stand Grow representative stand Produce volume yield streams Calculate available volumes
28
Measurement and Data Improvement Alternatives FIA ground survey plots are too sparse to provide information on sensitive areas. LiDAR and related systems could provide more accurate information on a timely basis at a competitive price. The information collected would be of value to a broader range of users to share costs.

Stand Structure for Habitat Suitability Johnson & O’Neil (2001) stand structures are available directly from LMS. Calculated from overstory QMD, Canopy Closure and Canopy Layers With the addition of Habitat Elements (snags, logs, etc.) are related to habitat use in Wildlife Habitat Relationship matrices (Johnson & O’Neil, 2001)
36
Stand Structures for “Traditional” Treatments
37
Habitat Suitability – single or indicator species Douglas Squirrel Need coniferous forests Common species Pileated Woodpecker Prefer complex forest structure Gold-Crown Kinglet Prefer closed forest structure Roosevelt Elk Large body size Prefer open structure
38
NP:Not Present – Species does not occur P:Present – Occasional use GA:Generally Associated – Supportive role for viability CA:Closely Associated – Essential needs Legend

Estimating Riparian Zone Impacts 1)Summarize stream mileage by owner type and stream type 2)Estimate riparian buffer acreage 3)Test validity using a LiDAR case study on streams with ground truthing (Mouton 2005)
