Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth
Electronic Theses and Dissertations
Historically, pheasants (Phasianus colchicus) have thrived in South Dakota in conjunction with successful land retirement programs or early farming practices through the 1950s, which created interspersions of agriculture and native landscapes that were ideal for pheasants. Recently, the Prairie Pothole ecosystem has undergone rapid agroeconomic expansion, effectively reducing ideal interspersions of native prairie and cropland into agriculturally homogeneous landscapes. Indices of pheasant abundance have suggested persistent population declines since 2008, raising concerns regarding landscape suitability. Our goal was to understand how agriculture intensification impacts pheasant ecology. The objectives were to: 1) estimate overwinter hen probability of survival, resource …

Characteristics And Use Of Wild Turkey Roost Sites In Southcentral South Dakota, Randall Allen Craft
Electronic Theses and Dissertations
Ten radio-tagged wild turkeys (Meleagris gallopavo)were monitored to document roost site use and bird movements in the Missouri River breaks complex of southcentral South Dakota during the summer of 1984. Distances between roost sites used by wild turkeys ranged from 0.55 km to 3.09 km. Primary and secondary roost sites were identified. Turkeys used one primary roost site consistently every night during periods ranging from a few days to 2 months, then moved to other primary roost sites. Secondary roost sites were used inconsistently by only a few birds that occupied the roost one night, and did not return on …
