  1. Alder Supply + Red Alder Plantation Growth and Yield RAP ORGANON Glenn AhrensOregon State University Extension Forester

  2. Agenda Hardwood Resource Supply • Review Hardwood Resource Situation in the Pacific Northwest - Key determinants of supply. • Lack of Current Data – Need for Updated Hardwood Resource Assessment?

  3. Hardwood Resource Data Sources • USFS Forest Inventory and Analysis (FIA) • 1997 - PNW-RB-237 Azuma et. al 2002 • 2001 - PNW-RB-246 Gray et. al 2005 • 2006 - PNW-GTR-765 Donneganet. al 2008 • 2006 - PNW-GTR-800 Campbell et. al 2010 • 2011 - ???????????????? • Washington DNR, Oregon Dept. of Forestry – Timber Harvest Reports • Washington Hardwoods Commission – processor reports

  4. Key Aspects of Hardwood Supply • Alder component has declined on the landscape and as % of harvest . • Alder “comes along” with softwood harvest –ups and downs of regional harvest trends. • Retention and management for alder in younger stands has increased. • Planting of alder has not “caught on”.

  5. Harvest – All species Alder Logs

  6. Knowledge of and management for alder is increasing.

  7. Foresters and landowners often leave alder in young stands when it appears to be the “best tree”.

  8. Industrial hardwood component is still declining. Hardwoods supply from non-industrial private woodlands increasing in importance.

  9. Is the worst over ? Loss of red alder forest type slowing down? Non - industrial Industrial Alig et al. 2000 PNW-RP-522. Forest Cover Dynamics in the Pacific Northwest West Side.

  10. Timber Trends on Private Lands in Western Oregon and Washington: A New Look Darius Adams & Greg Latta. 2007. West. J. Appl. For. 22(1)

  11. Legacy of abundant alder is diminishing 10% >> 7% >> ? The future depends on hardwood management

  12. Need for Updated Hardwood Resource Assessment? • Hardwood resource assessment would require funding and extra attention to the hardwood component - government analysts are not going to do it for us. • New analysis of public data? • Survey of industrial private forest management practices? • Another GIS study?

  13. Hardwood Timber Resources • Non-industrial forests have about half the hardwood , continue to regenerate hardwood, and provide growing share of supply. • Foresters are increasing alder management. • State Forests aim to provide consistent timber supply including red alder. • Social & Political Climate - Movement towards balance between economic and environmental?

  14. Summary - Hardwood Supply Situation • Recent harvest volume of alder is about half what it was 15 years ago. • Alder component declining on the landscape and as % of harvest. • Alder comes along with softwood harvest -regional harvest trend drives alder supply. • Available landbase and market factors drive forest harvest . • Alder retention and management – increasing.

  15. Outlook for Hardwood Timber Priorities for action • Increase public understanding and acceptance of forest management - maintain “license to practice forestry”. • Keep forest lands in forest – prevent conversion to non-forest. • Demonstrate success and increase professional knowledge and skills in Hardwood Management .

  16. Agenda Red Alder Plantation Growth and Yield – RAP ORGANON • Projecting yields from Plantations – thinned or not • Comparing alder with conifers • Growth and yield estimation tools for the future • User Interface for RAP – ORGANON • Yield from managing “incidental” alder?

  17. Collect stand data – dbh, height, crown ratio, plus stand age and dominant height. • Make projections of growth and yield

  18. Site specific comparison of alder vs conifers - projected yields and returns?

  19. NPV Interest Rate = 5%

  20. In search of a better user-interface for ORGANON.

  21. Excel Spreadsheet ORGANON interface – Doug Mainwaring OSU Draft, under development

  22. Red Alder Plantation Growth and Yield – RAP ORGANON • Projecting yields from Plantations & comparing alternative species – site quality assessment is key. • Growth and yield estimation tools for the future • Start with Excel User Interface for RAP – ORGANON • More needed to project yield from managing “incidental” alder.
