Impacts of the Western Spruce Budworm
The budworm moth prefers the upper to mid-crown section of larger host trees for depositing eggs. When the hatched larvae disperse small trees that are growing underneath or in close proximity to large trees may receive a disproportionate number of larvae. Small trees have a greater percentage of the preferred current-year foliage than large trees and as a result are subject to heavier defoliation during budworm outbreaks.
Impacts caused by Western Spruce Budworm outbreaks as they relate to forested land in the City of Kamloops include:
When negative impacts are weighed against the positive ones, a net overall loss of stand value is realized. Douglas-fir trees on the identified city land are a valuable commodity, as they represent the vast majority of the trees that will remain after the current mountain pine beetle epidemic is finished.
