Growing concern over sustainability of central ldaho forests has created a need to assess the health of forest stands on a relative basis. A stand hazard rating was developed as a composite of 11 individual ratings to compare the health hazards of different stands. The composite rating includes D...

Permanent plots were established in the Greater Yellowstone Area (GYA) following the 1988 fires to determine response of bark beetles to fire-injured conifers. Within 2 years (1989 and 1990), 67 percent of the Douglas-fir had been infested by bark beetles (primarily the Douglas-fir beetle) and wo...

Extensive surveys of bark beetles and wood bores in the Greater Yellowstone area were conducted in 1991 through 1993. The study objectives were to determine the effect of delayed tree mortality following the 1988 fires on mosaics of fire-killed and green tree stands, the relationship between fire...

Guidelines are presented to assist forest managers in integrating pest management techniques for the mountain pine beetle (Dendroctonus ponderosae Hopk.) with other resource considerations in the process of planning and executing balanced resource management of lodgepole pine (Pinus contorta var....
