This document summarizes information from a project at Hart Mountain National Antelope Refuge, Oregon, that studied the effects of prescribed fires on important foods of prelaying greater sage-grouse females and chicks. As of 2007, prescribed fire is no longer used in sagebrush communities on this refuge in order to preserve existing sagebrush habitat for greater sage-grouse and to reduce spread of cheatgrass, a nonnative annual grass [8]. This summary: •provides concise information about the effects of particular fire treatments on a Wyoming big sagebrush community and •supplements FEIS reviews of individual species with detailed information on specific treatments in southeastern Oregon. Studies summarized in FEIS Research Project Summaries are selected based on their integration of fire effects information with relatively complete descriptions of burned and unburned vegetation, burning conditions, fire weather, and fire behavior.
