This database contains records of grassland bird abundance and vegetation structure on tallgrass and mixed-grass prairies managed by the U.S. Fish and Wildlife Service (USFWS). Specifically, under the adaptive-management decision framework (Native Prairie Adaptive Management [NPAM] intiative), we surveyed breeding birds and sampled vegetation on 89 native prairie NPAM units managed by the U.S. Fish and Wildlife Service, including 55 units in 2011, 87 units in 2012, and 87 units in 2013. The NPAM units occurred in 19 USFWS refuge complexes and wetland management districts, including 14 complexes in USFWS Region 6 (North Dakota, South Dakota, and Montana) and five complexes in USFWS Region 3 (Minnesota).
