Forest cover type analyses in the 100 Mile House and Kamloops Timber Supply Areas Van Buskirk, Robert
Abstract
The debate surrounding the accuracy of the forest inventory in British Columbia has increasingly gained media attention in recent years. It is widely recognised by professionals within the forestry community that limitations exist with the current timber inventory. An analysis of selected forest cover types was conducted from operational cruise plots in the 100 Mile House and Kamloops Timber Supply Areas (TSAs) to examine possible differences in stand attributes from each data source. Forest cover types were stratified based on the spatial location within three biogeoclimatic subzones. Age and site index information were pooled from all available data sources due to limitations on available age data. The study determined that stand attributes in the IDFdk3 were overestimated and were undervalued in the MSxk2 and SBPSmk by the Vegetation Resource Inventory (VRI). Cruise information indicated that stand volumes were slightly higher relative to age in comparison to the VRI. This corresponded with a slight undervaluation by the VRI of site index. The study provides further confirmation that the VRI is not an accurate base for forecasting timber inventory for short term harvest planning horizons.
