Evaluation Of The Deadwood Bighorn Sheep Herd Translocation, Ty J. Werdel
Evaluation Of The Deadwood Bighorn Sheep Herd Translocation, Ty J. Werdel
Electronic Theses and Dissertations
From 2015-2017, we evaluated a newly established bighorn sheep (Ovis canadensis) herd in the Deadwood Region of the Black Hills, South Dakota. Our objectives were to 1a) determine annual survival rates, 1b) determine cause-specific mortality, 1c) estimate population size, 2a) assess genetic diversity, 2b) assess disease prevalence, 3) evaluate movement patterns post-release, 4a) evaluate 3rd-order habitat selection, and 4b) estimate herbaceous biomass at foraging sites post-release of translocated bighorn sheep. In February 2015, we captured and translocated 26 bighorn sheep from the Luscar Mine near Hinton, Alberta, Canada to the Deadwood Region of the Black Hills, South Dakota. Overall annual …
An Evaluation Of Deer And Pronghorn Surveys In South Dakota, Kristopher W. Cudmore
An Evaluation Of Deer And Pronghorn Surveys In South Dakota, Kristopher W. Cudmore
Electronic Theses and Dissertations
To properly manage white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus), and the American pronghorn antelope (Antilocapridae americana), wildlife managers must identify population perimeters, sample size, age and sex ratios of these three species. The primary objective of this study was to evaluate age and sex ratios and determine a minimum sample size for each study area for all deer species and pronghorn, in addition to deriving a methodology and population estimate for white-tailed deer in the Black Hills. Sample size needed for both species of deer and pronghorn ranged from 60-70 groups of does. Age ratios calculated from daylight …
Swift Foxes In Southwestern South Dakota: Assessing The Current Status Of A Reintroduced Population, Sarah Ann Nevison
Swift Foxes In Southwestern South Dakota: Assessing The Current Status Of A Reintroduced Population, Sarah Ann Nevison
Electronic Theses and Dissertations
Swift foxes (Vulpes velox) were reintroduced into Badlands National Park between 2003 and 2006 after being nearly extirpated from South Dakota in the early 1900’s. Genetic analysis provided strong evidence that the reintroduction was successful, but viability analysis indicated the population may be in jeopardy with a high probability of extinction. Recently, the population has declined due to various biotic and abiotic factors (e.g., recent weather patterns, effects of plague [Yersinia pestis], and increased coyote [Canis latrans] numbers). No information on the status of swift foxes has been collected since 2009. Between 2014 and 2016, the objectives of this study …
