2 Presentation Overview Project Objectives MPB in Merritt Basecase Sensitivity Analyses FFT Opportunity
3
3 Project Objectives Impact of MPB on harvest levels and other forest values such as wildlife habitat Evaluate how silviculture can reduce the impacts More specifically: When, and by how much, will the beetle affect timber supply Recommend and assess potential ways to improve timber supply and non-timber values Prioritize spending

11 Defining a Base Case Updated netdown; Updated resultant file, which includes an updated inventory; New analysis units and yield tables; Recalculation of the PSI for each resultant polygon; Old growth management area (OGMAs); Disturbing the inoperable; Updated UWR modelling; and MPB projections to 2015.

17
17 Return On Investment (ROI) Uses TIPSY to generate: Yield Tables Costs and Revenues Standardized FFT IRR Worksheet: Calculates ROI and NPVs
18
18 Example ROI Output ROI = 3.38%
19
19 Merchantability A tool for describing the relative economics of timber harvesting opportunities across a forested landbase. Merchantability = Product Value – Operating Costs
20
20 Merchantability- Product Value Product value approximates the selling price for lumber and chips Product Value is a function of: Site Index Species Stocking Age
21
21 Merchantability- Operating Costs Costs involved in operating, building roads, harvesting wood, manufacturing products and reforestation Operating cost is a function of: Slope Terrain Volume/ha Cycle time Species BEC zone Stocking Age
