Avian Response to Wildfire in Interior Columbia Basin Shrubsteppe
Wildfire and conversion of sagebrush (Artemisia spp.) shrublands to cheatgrass (Bromus tectorum) grasslands is a serious threat to the shrubsteppe ecosystem, but few studies have documented wildfire's effects on birds with multiple years of pre-and post-fire data. Using data from avian point co...
