3 Operation Overview 4 Timber Supply Areas, 3 Forest Districts, 3.6 million hectares 1.9 million m3 consumed All but JV volume third party SFM certified ~525 million board feet dimension lumber

4 What are Complex Stands? Growth and Yield Standards and Procedures (March 2003) 1. Not single storied 2. Not even aged

6 Management Application Stand Structure Classification 1995 FPC Needed means to rationalize silv system An Assessment of Opportunities For Alternative Silvicultural Systems in the the SBS, ICH, and ESSF Biogeoclimatic Zones in the PRFR. Weetman et al Collect Stand Structure data CC, LCR, acceptability, subplot Classify

7 Stand Structure Classification Con t Develop silv system options considering: Recommended option from Weetman et al Resource objectives Stand structure Operational constraints Business objectives Vast majority of stands examined, single storied, even aged. Consequently vast majority of harvesting utilized even-aged systems.

24 M53: Operational Strategies for CWD Management Maintain clumps of CWD and other structural elements Clumps could be built around: existing deadfall a group of snags (stubbed, with tops left in clump existing clump of immature trees alder patch (or other tall shrubs) existing deciduous or cull trees areas where machinery can t go

25 M53: Operational Strategies for CWD Management Keep the larger, longer logs intact and on the block don t skid unwanted logs identify unmerchantable stems at the stump and leave on site place unwanted snags in direction of skid to one side of skid route in or adjacent to clump applies particularly to snags with branches and bark

26 M53: Operational Strategies for CWD Management try not to disturb natural accumulations of downed logs if a tree or snag is felled and left, put it down across other logs (off the ground if possible). Maintain poles, saplings, deciduous and cull trees for habitat and future CWD

29 Challenges: Complex stands and M53 Timber pricing Take or Pay (Reserve Timber) Cruising policy Customer needs Forest Health (spruce Beetle) Operational challenges Safety Equipment Production Stand Damage Training Modeling complex stands

30 Challenges Knowledge Gaps or Research needs Variations in silv standards CWD strategy effective?

31 Summary Operations conducted primarily in single storied, even aged stands Limited experience in complex stands, can meet non timber objectives; premium to timber (on truck) CWD BMP s are well suited to stands with abundant poles and saplings. Completed one monitoring cycle, room to improve. Number of policy and operational challenges affecting our ability to operate.
