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....


The addition of more than 900 plots to the Daubenmire's original 181-plot database has resulted in a refinement of their potential natural vegetation-based land classification for northern Idaho. A diagnostic, indicator species-based key is provided for field identification of the eight climax se...
