Spruce Beetle Effects on a White Spruce Stand in Alaska
View through CrossRef
Abstract
A severe infestation of spruce beetle (Dendroctonus rufipennis Kby.) in a white spruce (Picea glauca [Moench] Voss)-paper birch (Betula papyrifera var.) stand caused 64.6 percent mortality of spruce 5 inches d.b.h. and larger where the infestation was completed. Survival of spruce was
greater in smaller diameters. Birch is the dominant tree species in the residual stand.
