| dc.description |
Mountain pine beetle populations increased to epidemic levels on
the Kootenai National Forest in 1972. Nearly 397,000 trees containing
almost 32 million board feet have been killed. More than
84,000 trees will probably be killed in 1978. Infestation has
the potential to intensify in high hazard stands, and some increase
may occur in stands of low and moderate hazard. Potential losses
can be reduced through an accelerated program of (1) sanitation
salvage cutting and (2) silvicultural management. High-hazard
stands should receive first priority. |
