| dc.description |
Mountain pine beetle populations reached epidemic levels on approximately
4,600 acres in Glacier National Park in 1972. Infested trees
increased from 4.9 in 1972 to 10.9/acre in 1975. Majority of trees
killed since 1972 were 12 inches d.b.h. and larger in size. Sufficient
large diameter lodgepole pine exists to maintain the infestation at
epidemic level for several years. |
