Forest operations Felling, processing, transportation

Logging schedule Estimated volumes/areas/yields

Current volumes/areas and percentages of fuel wood and sawlog (Forest Inventory andAnalysis Branch)

5,10 and 20-year volumes/areas and percentages of fuel wood and sawlog (FERICsshelf life model)

Skidding distance (Average of 200m) Equipment data

Production rates Horse power Speed (Empty and full)

Average hours before failure Average maintenance hours

Cost data (Equipment Rental Rate Guide) Hauling Distances

MPB Problem in Interior BC The largest recorded outbreak in NA

http://www.for.gov.bc.ca/hre/bcmpb/cumulative/1999.htm

Over 400 M of dead wood

Over 8 Mha of infested area MPB Action Plan

Increase AAC levels Recover the greatest value from dead

timber before it burns or decays
