| dc.description |
Mountain pine beetle developed to epidemic level in lodgepole
pine stands in 1969 on the Gallatin District and in 1970 on the
Hebgen Lake District. Epidemic infestation occurs on 53,437
hectares. Infestations will intensify in most areas currently
infested and develop in uninfested stands, and in excess of 2
million trees could be killed in 1977. Salvage logging to remove
brood trees and silvicultural management to reduce average stand
diameter below 20.3 cm d.b.h. are recommended to manage the
infestation. |
