Spruce budworm disturbance of the boreal forests in the Ft. Nelson District of British Columbia: assessing forest damage, risk, and ecosystem

Series: Forest Investment Account (FIA) - Forest Science Program


We study budworm disturbances in the Fort Nelson District, producing information needed for sustainable forest management. Using dendro-chronology methods we will determine the historical frequency of budworm in this District. Using remote sensing methods we will measure past and present changes of this disturbance and provide methods for continued use in this District and elsewhere. Composite databases, including ground, aerial and satellite measurements of budworm disturbance will be intersected with landscape attributes, to determine patterns that increase budworm susceptibility. We will measure the impact of defoliation on ecosystem functions, including stand composition, age, regeneration, coarse woody debris, snag availability.
