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

2 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

4 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 10 Merritt MPB Projections by Severity

11 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.

12 12 Base Case

13 13 Conversion to Managed

14 14 Harvest by Species

15 15 ECA by CWS

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

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

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

23 23 Merchantability- Map product

24 24 Merchantability- Area Summary

25 25 Sensitivity Analyses

26 26 Harvest all MPB Very Severe

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

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

29 29 Faster MPB Spread

30 30 Presently Utilized Uplift Level

31 31 Retain 150m 3 /ha non-Pl

32 32 Kill MPB down to 10cm DBH

33 33 Two year shelf life

34 34 Two year shelf life-Availability

35 35 Plant GI spruce instead of pine

36 36 Retention Sensitivities

37 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

38 38 FFT Opportunity Scenario

39 39 FFT Opportunity Age class

40 40 FFT Opportunity ECA Impact

41 41 FFT Planting Opportunity

42 42 Classification of Landbase

43 43 Classification of Landbase

44 44 Environmental Reporting  Seral Stage  Patch Size  Fine filter- UWR/Grizzly/Woodpecker  Harvest in FN Retention Area  CWS- ECA/Road Density/Seral stage

45 45 Seral Stage

46 46 Harvest in FN Retention Areas  No harvest in FN 100% for 15 years

47 47 Patch Size

48 48 CWS ECA

49 49 CWS Seral Stage
