  1. Canadian Forest Service Activities in Support of Growth & Yield Research in North-Central B.C. Phil Burton UNBC, 29 June 2005

  2. The CFS does not have a G&Y program. … but …

  3. We do have: • G&Y expertise; • Data/models on stand dynamics associated with insects and diseases; • Long-term silvicultural trials; • National Forest Inventory (NFI); • Strong emphasis on carbon stocks and carbon dynamics.

  4. Expertise: • E.g., Steen Magnussen • 2005. A variance estimator for constrained estimates of change in relative categorical frequencies. Environmental Monitoring and Assessment 105: 391-410. • 2002. An inverse gaussian distribution of tree frequencies based on tree size. Environmental and Ecological Statistics 9: 27-42. • 2002. Evaluation of probability proportional to predictions estimators of total stem volume. Canadian Journal of Forest Research 32: 92-102. • 1999. Effect of plot size on estimates of top height in Douglas-fir. Western Journal of Applied Forestry 14(1): 17-27.

  5. Stand Dynamics Associated With Insects and Diseases: • E.g., The Root Rot Tracker Fred Peet

  6. Stand Dynamics Associated With Insects and Diseases: • E.g., Armillaria impacts on stand development and productivity Mike Cruickshank

  7. Stand Dynamics Associated With Insects and Diseases: • E.g., Chilcotin, pre-MPB, post-MPB, and 18-yrs post-MPB Terry Shore, Brad Hawkes & Steve Taylor

  8. Long-Term Silvicultural Trials: • Especially for lodgepole pine, mostly Southern Interior -- Roger Whitehead

  9. Long-Term Silvicultural Trials: • Especially for lodgepole pine, in Alberta -- Jim Stewart & Richard Yang, NoFC

  10. Long-Term Silvicultural Trials: • More recently for mixedwood, especially in Alberta – • EMEND, Hotchkiss River, Alcott Creek Derek Sidders & Dan MacIsaac, NoFC

  11. National Forest Inventory (NFI): • Designed for 10-yr monitoring interval • photo-plot and ground-plot components • 20-km grid for 2 km x 2 km photo-plots • Ground plots at 8% of sites, in support of CCFM C&I, C budget monitoring, etc. Mark Gillis

  12. Forest Carbon Accounting, Modelling & Climate Change: Werner Kurz m3 wood  kg dry wt biomass   kg C

  13. CFS Summary • Support, but not lead, G&Y research • Facilitate continuity and collaboration within the region • Link to national interests in C&I reporting, risk analysis, carbon accounting & climate change
