| dc.description |
Mountain pine beetle activity has increased from about 350 infested trees
in 1972 to over 1,200 infested trees in 1974 on the Bitterroot National
Forest. The majority of infestation occurs in second-growth, overstocked,
ponderosa pine stands in the West Fork Bitterroot drainage. An increase
in number of trees killed is expected in 1975. Commercial thinning is
encouraged to remove infested trees and improve stand vigor to reduce
the infestation to endemic levels. |
