Cheyenne Bottoms Wildlife Area (CBWA) is an internationally recognized wetland surrounded by mixed-grass prairie. Because habitat management historically has been focused on the marsh, this study was initiated to determine the effects of spring burning on abundance and species richness of grassland-nesting birds. The effects of years since last burn and location on abundance and species richness were inconsistent among years. Unless additional bird surveys show consistent patterns in bird response to burning, frequency of burns will be determined based on vegetation characteristics rather than abundance of nesting birds.
