| dc.description |
Mountain pine beetle has occurred at epidemic level in lodgepole
pine stands in the west Gallatin River drainage since 1969. Infestation
now encompasses about 5,500 acres. Since 1969, approximately
463,212 trees, with an estimated volume of 20,529,244 board feet have
been killed. Approximately 69 percent of the stands on the Gallatin
District are classed as susceptible. It is predicted that about
927,781 trees will be killed in 1976. Selective logging to remove
infested and susceptible trees is recommended to reduce the potential
for a continued epidemic. |
