Captured adult ( 1.5 years old) deer were ttonsil biopsies and monitored us survival rates of CWD-negative and 0.32, respectively. Pregnanc. We estimated λ = 0.79, indicating an annual population declinem the demography of only CWD-negative individuals yielded; λ = 1ndings support CWD as a significant contributor to mule deer popble to eradicate with current tools, given significant environmeontrol of this disease is to minimize spread to new areas and naCronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy affecting white-tailed deer (Odous virgius), mule deer (y Mountain elk (us nelsoni), andAlces alces shirerica. In southeverage annual CWence in mule deed appears to conlation declines. We determined t on mule deer demography using aale-only, CWD transition matrix n growth rate (λ). Mule deer werthern Converse County Wyoming, Uested ante-mortem for CWD using ing radio telemetry. Mean annualand CWD-positive deer were 0.76 y and fawn recruitment were not observed to be influenced by CWD of 21% under current CWD prevalence levels. A model derived fro.00, indicating a stable population if CWD were absent. These fiulation decline. Chronic wasting disease is difficult or impossintal contamination, and at present our best recommendation for cïve cervid populations.
