[QUOTE="flounder, post: 1815145, member: 3519"] cwd population declines CWD poses a significant threat to the future of hunting in Texas. Deer population declines of 45 and 50 percent have been documented in Colorado and Wyoming. A broad infection of Texas deer populations resulting in similar population impacts would inflict severe economic damage to rural communities and could negatively impact land markets. Specifically, those landowners seeking to establish a thriving herd of deer could avoid buying in areas with confirmed CWD infections.

Executive Summary Mule deer, white-tailed deer, elk and moose are highly valued species in North America. Some of Colorado's herds of these species are increasingly becoming infected with chronic wasting disease(CWD). As of July 2018, at least 31 of Colorado's 54 deer herds (57%), 16 of43 elk herds (37%), and 2 of 9 moose herds (22%) are known to be infected with CWD. Four of Colorado's 5 largest deer herds and 2 of the state's 5 largest elk herds are infected. Deer herds tend to be more heavily infected than elk and moose herds living in the same geographic area. Not only are the number of infected herds increasing, the past 15 years of disease trends generally show an increase in the proportion of infected animals within herds as well. Of most concern, greater than a 10-fold increase in CWD prevalence has been estimated in some mule deer herds since the early 2000s; CWD is now adversely affecting the performance of these herds. snip...(the map on page 71, cwd marked in red, is shocking...tss) [URL]https://cpw.state.co.us/Documents/RulesRegs/Brochure/BigGame/biggame.pdf[/URL] [URL]https://cpw.state.co.us/Documents/Hunting/BigGame/CWD/PDF/ColoradoChronicWastingDiseaseResponsePlan.pdf[/URL] Since identifying its first cases of CWD in captive deer in the 70s and finding the first wild infected deer in 1985, Wyoming has seen the disease slowly spread throughout the state.

How does CWD impact deer, elk, and moose populations? Recent research in Wyoming has demonstrated declines in both mule and white-tailed deer populations in deer hunt area 65 due to CWD (see below for citations). These declines are in the core endemic area where prevalence is highest. In areas with lower prevalence, effects of CWD are poorly understood but are considered additive along with other factors that can negatively affect deer populations in Wyoming (i.e. habitat loss, predation, other diseases).

Prevalence increased by about 10%, to 14%, in the Uncompahgre herd, and grew from 3.5% to 8% in the Middle Park herd. Prevalence fell from 13.6% to 6.7% in the Sweetwater herd and from 12% to 8% in the Big Thompson herd. Parks and Wildlife has detected the disease in 40 of Colorado's 54 deer herds, 17 of its 42 elk herds and two of its nine moose herds.

In one herd, the prevalence rate is calculated at 65% in mule deer bucks, and there are concerning increases in infected elk, including hunt areas popular for Big Horn Basin hunters. The disease, which typically kills infected animals within two years after initial exposure, now occurs in 34 of Wyoming's 37 mule deer herds, and 15 of the state's 36 elk herd units.
