8. Accounts by early explorers and surveys Past harvesting and other disturbances Fire and lightning data Fire scars and tree rings

9. A complex mixed-severity fire and insect disturbance regime likely shaped historic conditions Choosing a point in time for reference conditions is problematic making “ecosystem restoration” difficult Identify key and measurable resource management objectives (e.g. human safety, wildlife habitat, livestock forage) Some Key findings

Distribution ecology of lichens in ICH MacrolichenCalicioid lichen Comparison of young and old stands Habitat requirements for old-growth-associated species Cyanolichen distribution and tool for predicting diversity hot-spots Information used during LRMPS Many papers, presentations, Best paper award, new hypotheses Inland rainforests Provided assistance to Arrow/Boundary District And Pope and Talbot in the Incomappleux

15. Management Issue: Can we harvest timber and maintain caribou winter habitat ?

16. Mountain caribou Northern caribou

17. Group Selection based on openings up to 1.0 ha

18. Response of arboreal lichen biomass and composition

19. Conclusions: After 10 years post-harvest, the residual forest continues to provide adequate lichen forage for caribou. There is acceptable regeneration of the treatments, and there are minimal impacts on biodiversity (birds, small mammals, plants).

20. Management Issue: Are there alternatives to clearcutting that managers can use to address issues such as visual quality and species selection?

21. Uniform shelterwood silvicultural systems

22. Douglas-fir is an important species for timber harvesting and biodiversity. Can Douglas-fir be regenerated and grown on frost prone sites in the SBS using various levels of residual basal area retention?

23. Uniform shelterwoods or variable retention treatments can be used to manage visual quality and biodiversity but what are the implications to regeneration and overstory trees when partial cutting on root disease infected sites? Ice Road near Nakusp Mount Seven near Golden

24. Conclusions: The SBS shelterwood trial is adequately stocked with Douglas-fir in the seed cut treatments and the final cut is scheduled for 2010. The ICH trials are successfully regenerated with several species but growth is affected by the residual basal area. Survival is just starting to be affected by Armillaria.

25. Regeneration and Stand Tending Regeneration in non-conventional silvicultural systems (i.e. small gaps, under shelterwoods) Brushing (including broadleaf species) Stand rehabilitation Growth and yield of mixed species stands Site preparation / planting treatments Species Selection Density management Fertilization

26. Issue: How many aspen can be retained in a pine stand without compromising conifer productivity? Or to Brush or not to brush!!

27. Depends on where you are SBSdw1 SBPSxc IDFdk

28. And how much you have You can keep some

29. Current outcomes Identified “best” method to predict level of competition in the field Free growing guidelines have been altered Able to predict future growth under different competitive environments

30. Issue: Over 130,000 ha of height repressed pine

31. Possible Solutions Keep current growing stock – stand tending options Start over – rehabilitation options

32. Outcomes: Fertilization / thinning worked (36 years old in the SBPSdc)

33. Program Challenges To continue to address high profile issues: provincially and regionally To promote implementation of research results where applicable and relevant

34. Program Successes *A network of well designed long-term research installations that are used for continuous learning by a diverse research community even within changing environments *Knowledge transfer to foresters, students, the public and the academic community *Continuous success in securing research funding through competitive process
