Abstract:

Surveys of bark beetle and wood borer infestation in the Greater Yellowstone Area were conducted from 1991 through 1993 to determine the effect of delayed tree mortality on mosaics of fire-killed and green tree stands, the relationship between fire injury and infestation, and the effect of insect buildup in fire-injured trees on infestation rates for uninjured trees. Fire injury accounted for more delayed mortality than insect infestation, but both types of mortality greatly altered the mosaics immediately apparent after the 1988 fires. The high level of infestation suggests that insects built up in fire-injured trees and then caused increased infestation of uninjured trees.
