Data from: Long-term trends in grassland bird relative abundance on focal grassland landscapes in Missouri
North American grassland birds have widely declined over the past 50 years, largely due to anthropogenic-driven loss of native prairie habitat. In response to these declines, many conservation programs have been implemented to help secure wildlife habitat on private and public lands. The Grasslands...

North American grassland birds have widely declined over the past 50 years, largely due to anthropogenic-driven loss of native prairie habitat. In response to these declines, many conservation programs have been implemented to help secure wildlife habitat on private and public lands. The Grasslands Coalition is one such initiative established to advance the conservation of grassland birds in Missouri. The Missouri Department of Conservation conducted annual point count surveys for comparison of grassland bird relative abundance between focal grassland areas and nearby paired (i.e., containing no targeted management) sites. We analyzed 17 years of point count data with a generalized linear mixed model in a Bayesian framework to estimate relative abundance and trends across focal or paired sites for nine bird species of management interest that rely on grasslands: barn swallow ( Hirundo rustica ), brown-headed cowbird ( Molothrus ater ), dickcissel ( Spiza americana ), eastern meadowlark ( Sturnella magna ), grasshopper sparrow ( Ammodramus savannarum ), Henslow's sparrow ( A . henslowii ), horned lark ( Eremophila alpestris ), northern bobwhite ( Colinus virginianus ), and red-winged blackbird ( Agelaius phoeniceus ).
