The primary goal of this research Project was the utilization of stand tending as a means of reducing the vulnerability of white spruce stands to budworm defoliation.
Objectives included determining the extent that cutting patterns, intensity and their interaction affect stand vulnerability to budworm damage; and determining the extent to which budworm populations are affected by changes in their disperal, natural enemy complex, host conditions and fecundity induced by cutting patterns & intensities.
This Project was initiated in 1996 and for its first year (1997) was funded directly by several forest companies. Progress Reports covering 1997, 1998 & 1999 are provided as "deliverables" under DMI-01-05. Work is continuing under Project No. TOLKHL-01-06 and the final reports will be provided thereto.
