  1. The Evolution of Forest Inventory on the Warm Springs Indian Reservation Allan D. Derickson Forest Planning & Inventory Supervisor Confederated Tribes of Warm Springs

  2. East Slope Cascades 1,000 ft to 10,000 ft Kah-Nee-Ta Reservation established in 1855 for Wasco and Warm Springs Indians Paiutes added in 1879

  3. Warm Springs Forest Management • 644,000 total acres • 423,000 forested acres • 315,000 unreserved forested acres • 256,000 net commercial forest acres • Over 3 billion board feet of inventory • 25 commercial tree species • 27 different plant associations

  4. Warm Springs Forest Management • 1992 - Integrated Resource Management Plan • Traditional Cultural Uses • Water and Fish • Wildlife • Timber • Grazing • Other Economic Development • Recreation

  5. Harvest Scheduling Constraints • Must plan by watershed (12) • Retention trees at 5-15 tpa • Minimum stand age requirements: 70 years • Selected stands constrained temporarily for wildlife cover • Harvest priority respected. No low or stable OG

  6. Harvest Priority

  7. Conditional Use Areas • Have one or more of the following: • Extremely low productivity • Very difficult logging or access • Possess other high resource values • Spiritually significant to Tribal Members • Harvest timber only at Tribal Council direction • Not scheduled or included in allowable cut

  8. 99 3-plotclusters

  9. 1966 249 3-plotclusters

  10. 1972 289 3-plotclusters

  11. 1974 McQuinn Strip

  12. -99 1380 plots

  13. 1988: CFI Design Changed • Single plot on a 50x50 chain grid replaced 3-plot cluster on 100x100 chain grid • Subplot 1 remeasured • Subplot 2 remeasured for the last time • Subplot 3 dropped • 1/100 acre regeneration plot added in the Pine type • Conditional Use plots not remeasured

  14. 1997: CFI Plots GPS’ed • Conditional Use plots remeasured • Taper heights measured • 1/100 acre regeneration plot on all plots • CFI not used for AAC • CFI was used to calibrate both FPS and FVS growth models • CFI used to compute growth & mortality

  15. The Stand Exam Program • 1993: A need for more detailed stand-based data to implement IRMP • Stand health and structure important • USFS R6 Stand Exam protocol adopted • Atterbury SuperStand • 2 types of exams: “Formal” & “Walk-through”

  16. The SE Program Evolves • Switch to MB&G SIS compiler and inventory database • “Walk-Throughs” eliminated • Data used for AAC calculation • Count plots used to improve statistics

  17. Evolution Continues • 1999: Eastern Oregon FPS library available • FPS offered a more integrated compiler-growth model-harvest scheduler • 2001: AAC calculated with FPS • Stocking survey data used to supplement SE • 2002: Prescribed fire monitoring begun

  18. The Wilcox Stocking Plots • 1985: Need to find appropriate level of stocking for uneven-age management in PP type • 4 areas selected to install 3 sets of 2.5 acre plots • 3 different levels of retention • All tree >1.5 inches dbh measured and stem-mapped • Remeasured at 5 year intervals

  19. Upper Tenino Plot 3

  20. The Future • Continue to improve accuracy and efficiency • Gather data on 12,000 acres a year • Use data from other programs to bolster SE • Have an inventory program second to none
