| dc.description |
Mountain pine beetle developed to epidemic levels in lodgepole
pine stands in the Thompson River drainage in 1971. Approximately
506,616 trees are infested on 4,444 hectares. Based on buildup
ratios, infestations are expected to intensify; develop in uninfected
stands; and kill about 1,763,024 trees in 1977. Salvage
logging of infested trees and silvicultural management to reduce
the average stand diameter below 20 cm d.b.h. are recommended to
manage the infestation. |
