Book Description
Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

Book Description
The white pine weevil, Pissodes strobi Peck, can be found in nearly all regions of Canada and the U.S. It causes severe deformity and growth losses by damaging a tree's leader, which results in reduction of merchantable wood volume. These attacks threaten Sitka spruce plantings by the forest industry in B.C. In eastern Canada it limits the planting of eastern white pine and spruce. The goals of the White Pine Weevil Workshop were to consolidate current scientific knowledge and to map out a strategy for future research and funding requirements. 33 papers were presented on weevil research and management including biology and damage; genetics, weevils and hosts; and silviculture and control.
