Ministry of Forests Annual Report 1995/96
Table C–2o: Timber damaged by forest pests1 in 1995/96, by forest region
1Best available estimates of current annual losses. Accuracy varies, depending on the pest. Only the major forest pests of B.C. are included. (Balsam bark beetle, while considered a major pest, is not included in these estimates.) Volumes are estimates before salvage. Attacked timber is salvaged wherever practical.|
2Estimates for losses occurring on the net land base for dwarf mistletoes and root diseases.
3Volume lost to decay in forests exceeding 100 years of age is not included. This is estimated at 10 million cubic metres per year. Nursery and regeneration losses due to other insects, diseases and unwanted vegetation are also not included.
