We have determined that the average provincial site index has been underestimated by about 4 metres in lodgepole pine and about 6.5 metres in spruce.
Findings show the same trends for all species and biogeoclimatic zones studied.
Better site productivity information affects planning, timber supply analysis, silviculture investment analysis, land use allocation, operability estimates and a host of other considerations, said Pedersen. Colleen McKendry, site productivity coordinator at Resources Inventory Branch, explains that the OGSI project involves inventory, research, forest practices, and timber supply branches and all 6 forest regions. Although the majority of the research has been based on paired plot comparisons, other methods for estimating site productivity are being evaluated, Colleen notes. As research findings are finalized, they will be incorporated into timber supply reviews and other resource management processes, notes Colleen. Complete results and reports will be published in the spring of 1998.
