| dc.description |
Mountain pine beetle populations developed to epidmic level on the
Bozeman-Gallatin Ranger District in 1969. Approximately 146,000 acres
are currently infested. Since 1969, over 350 MMBF have been killed.
It is predicted that over 4 million trees could be killed in 1978.
Infestation is predicted to intensify in high-hazard stands.
Populations have declined in areas where infestation first developed
in 1969. 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. |
