1 Merritt TSA Type II Silviculture Analysis Merritt, B.C. April 5th, 2007

2 Presentation Overview  Project Objectives  MPB in Merritt  Basecase  Sensitivity Analyses  FFT Opportunity

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

4 Classification of Land Base TSA Area Retention No Treatment Partial Cut Restoration to Enhance Major Salvage Basic Obligations Silviculture Opportunity Basic Silviculture: Fire/Pest Incremental Silv.: Fert., Thin, Prune

10 Merritt MPB Projections by Severity

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.

16 -Return on Investment (ROI) -Merchantability Economic Indicators

17 Return On Investment (ROI) Uses TIPSY to generate: Yield Tables Costs and Revenues Standardized FFT IRR Worksheet: Calculates ROI and NPVs

18 Example ROI Output ROI = 3.38%

19 Merchantability A tool for describing the relative economics of timber harvesting opportunities across a forested landbase. Merchantability = Product Value – Operating Costs

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 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

22 Merchantability- Index Each stand given a Merchantability Class Summarized by graphs and maps

27 Plant all unharvested MPB Plant 122,000 ha Mid term increase: 370,000 m 3 /year

28 Plant Unharvested MPB-ROI > 2% Plant 89,000 ha Mid term increase: 370,000 m 3 /year

29 Faster MPB Spread

35 Plant GI spruce instead of pine

36 Retention Sensitivities

37 FFT Opportunity Scenario  Increased Planting of Genetically Improved Spruce  Plant all unharvested MPB kill with an ROI > 2%  CWS Restoration (planting) occurs irrespective of ROI  Retention of 100% FN Retention areas
