- Provide information related to any weather/habitat factors, public or private land use or resident and nonresident hunting opportunity that have relevance to this change (i.e., habitat security, hunter access, vegetation surveys, weather index, snow conditions, and temperature / precipitation information).
Most white-tail deer within the proposed CWD management hunt area occupy private lands within valleys. A small proportion distribute across adjacent public lands during snow-free periods of the year. These deer typically migrate into the valleys following initial snowfall. It’s anticipated that a high majority of white-tailed deer within the proposed CWD management hunt area would be distributed across private lands during the proposed hunt extension period. Access to hunt deer on private lands is attainable to hunters that properly pursue permission. Most private landowners issue permission to a limited number of hunters at any time for safety reasons and because this approach is believed to facilitate greater deer harvest per day. Thus, it is hypothesized that a level of deer harvest that would result is effective population reduction will require greater that 37 days of rifle hunting.
CWD was detected among white-tailed deer in the Ruby Valley in 2019. These deer are contiguous with white-tailed deer and moose throughout the Ruby, Jefferson, Beaverhead, and Big Hole valleys. They are seasonally connected to migratory populations of elk, moose, and mule deer that occupy adjacent upland habitats.
As of November 20, 2020, surveillance of hunter-harvested white-tailed deer suggests CWD prevalence of: 8.3% (N = 30) in Hunting District 320; 21.8% (N = 226) in Hunting District 322, 0% in Hunting Districts 324 (N = 2), 325 (N = 19), 329 (N = 2), 331 (N = 2), and 340 (N = 33); and 40% (N = 5) in Hunting District 326. Surveillance suggest CWD prevalence may be as high as 42% in a localized portion of Hunting District 322 where approximately 2,000 white-tailed deer are routinely counted at spring green-up. Because of high densities and contiguous distribution of white-tailed deer within these areas, CWD is expected to occur in areas it currently doesn’t soon. Without substantial reductions of white-tailed deer population and CWD prevalence, CWD is expected to result in white-tailed deer population reduction and transmit to adjacent populations of mule deer, elk, and moose soon.
Given current white-tailed deer density and the presence of CWD, substantial reduction of white-tailed deer density within these areas should be pursued. Future population management will need to be adaptive relative to CWD prevalence.
- Briefly describe the contacts you have made with individual sportsmen or landowners, public groups or organizations regarding this proposal and indicate their comments (both pro and con).
Because of the evolving nature of CWD detection and the need to act in a timely manner, the proposal has been discussed with a relatively small number of area landowners, sportsmen, and game wardens. Dillon biologist Jesse Newby and Butte biologist Vanna Boccadori, who manage hunting districts in this proposal, support this proposal. All sportsmen and landowners consulted were supportive of the proposal. Two landowners that control most of the lower Ruby Valley, where CWD occurs at relatively high prevalence and white-tailed deer densities are the highest, are supportive of continued hunting. The proposal may cause concern by some hunters and landowners where white-tailed deer populations remain relatively low. Within the proposed hunt area, individual landowners will maintain the ability to deny hunter access where they feel harvest is not necessary. Some hunters that desire more white-tailed deer may be opposed. There may be some opposition to including buck deer. However, buck deer harvest is critical to managing CWD prevalence and spread. Given high populations, chronic game damage, hunter interest in white-tailed deer harvest, and recent CWD surveillance results, the proposal is expected to be supported or accepted by most hunters and landowners.
