| dc.description |
Mountain pine beetle populations began building
in the Kootenai National Forest in 1972. Infestations now encompass an estimated 48,599
acres of lodgepole pine type and 615 acres of
ponderosa pine type. Approximately 25 percent
of the high-risk stands, 17 percent of the
moderate-risk, and less than 1 percent of the
low-risk stands are infested. Newly attacked
trees averaged 10 per acre. Infestations have
the potential to intensify in high-risk stands,
with some increase in moderate- and low-risk
stands. Predicted trends, plus management
alternatives to prevent and/or reduce infestation
severity, are discussed. |
