Passerine Use Of Grasslands Managed With Two Grazing Regimes On The Missouri Coteau In North Dakota, Natoma A. Schneider

Electronic Theses and Dissertations

Several rotational grazing systems have been implemented on the Missouri Coteau in central and northcentral North Dakota as part of the Prairie Pothole Joint Venture (PP N). The impacts these systems have on grassland passerines are not fully understood. Objectives for this study include determining relative abundance, species composition and reproductive success of passerines as well as vegetation characteristics for rotational and traditional season-long grazing regimes. Passerine relative abundance and species richness were determined on rotational grazing systems during 1995-1997 and on season-long grazed pastures during 1996-1997 using 122 fixed, 100 m radius, point counts. Relative abundance was assessed by …
