| dc.description |
Mountain pine beetle reached epidemic levels in the Lazier-Meadow
Creek drainages on mixed ownership in 1972. A total of 118,486
trees with an estimated volume of 5,666,124 board feet was killed
from 1972 through 1974. Presence of overstocked, mature, nearly
pure lodgepole stands, coupled with favorable weather conditions,
are believed to be responsible for outbreak development. Prompt
salvage logging of infested and susceptible trees, and conversion
to a mixed species stand, compatible with the designated habitat
type and site index, are recommended to alter the course of the
outbreak. |
