SOUTHEAST,Wis.– As spring thaw occurs and more wildlife are visible on the landscape in search of food, residents and hunters of Washington County are reminded that they are now included in the ban on baiting and feeding of white-tailed deer.
This ban, put in place by the Department of Natural Resources, is in accordance with existing state law, due to the discovery of two deer in Waukesha County that tested positive for chronic wasting disease in 2013.
Washington County is within a 10-mile radius of the northernmost Waukesha County property on which a CWD-positive deer was found. State law requires that counties within a 10-mile radius of a game farm or free-ranging CWD-positive deer are included in the baiting and feeding prohibition.
“Baiting and feeding of deer unnecessarily increases the risk of spreading CWD and other diseases,” said Tom Hauge, director of the DNR Bureau of Wildlife Management. “Animal health is important to preserving our great hunting tradition, is a foundation of tourism and vital to local businesses.”
Baiting and feeding increase risks of spreading communicable diseases, like CWD, by concentrating deer in one spot. Deer using one spot are more at risk for spreading a disease.
No changes are planned for the 2013 deer hunting season rules in the affected counties other than the ban on baiting and feeding, said Hauge.
Hunters will be asked to provide tissue samples from deer killed in the vicinity of the CWD- positive deer for further surveillance testing. Samples may also be collected from road kills, urban deer removal programs, taxidermists, and meat processors. Details of the sampling and testing program will be shared widely in subsequent news releases and at dnr.wi.gov, search keyword “CWD,” as the details are finalized.
Individuals can still feed birds and small mammals provided the feeding devices are at a sufficient height or design to prevent access by deer and the feeding device is within 50 yards of a human dwelling. For more information, please visit dnr.wi.gov, search keyword “CWD.”
these shooting pens are nothing more than a petri dish for infectious disease, especially CWD. we cannot risk the wild herds. the risk is too large.
one shooting pen in Wisconsin had the highest recorded CWD infection rate ever recorded, 80% CWD infection rate. that one game farm cost Wisconsin a world of hurt $$$ how many states have $465,000., and can quarantine and purchase there from, each cwd said infected farm, but how many states can afford this for all the cwd infected cervid game ranch type farms ??
? game farms in a state X $465,000., do all these game farms have insurance to pay for this risk of infected the wild cervid herds, in each state ??
The CWD infection rate was nearly 80%, the highest ever in a North American captive herd.
RECOMMENDATION: That the Board approve the purchase of 80 acres of land for $465,000 for the Statewide Wildlife Habitat Program in Portage County and approve the restrictions on public use of the site.

Prevalence and Surveillance
Originally recognized only in southeastern Wyoming and northeastern Colorado, USA, CWD was reported in Canada in 1996 and Wisconsin in 2001 and continues to be identified in new geographic locations (Figure 1, panel A). CWD has been identified in free-ranging cervids in 15 US states and 2 Canadian provinces and in ≈100 captive herds in 15 states and provinces and in South Korea (Figure 1, panel B).
CWD surveillance programs are now in place in almost all US states and Canadian provinces (Figure 2, panel A). More than 1,060,000 free-ranging cervids have reportedly been tested for CWD (Figure 2, panel B) and ≈6,000 cases have been identified (Figure 2, panel C) according to data from state and provincial wildlife agencies.
Testing of captive cervids is routine in most states and provinces, but varies considerably in scope from mandatory testing of all dead animals to voluntary herd certification programs or mandatory testing of only animals suspected of dying of CWD.
Long-term effects of CWD on cervid populations and ecosystems remain unclear as the disease continues to spread and prevalence increases. In captive herds, CWD might persist at high levels and lead to complete herd destruction in the absence of human culling. Epidemiologic modeling suggests the disease could have severe effects on free-ranging deer populations, depending on hunting policies and environmental persistence (8,9). CWD has been associated with large decreases in free-ranging mule deer populations in an area of high CWD prevalence (Boulder, Colorado, USA) (5). In addition, CWD-infected deer are selectively preyed upon by mountain lions (5), and may also be more vulnerable to vehicle collisions (10). Long-term effects of the disease may vary considerably geographically, not only because of local hunting policies, predator populations, and human density (e.g., vehicular collisions) but also because of local environmental factors such as soil type (11) and local cervid population factors, such as genetics and movement patterns (S.E. Saunders, unpub. data).
Controlling the spread of CWD, especially by human action, is a more attainable goal than eradication. Human movement of cervids has likely led to spread of CWD in facilities for captive animals, which has most likely contributed to establishment of new disease foci in free-ranging populations (Figure 1, panel A). Thus, restrictions on human movement of cervids from disease-endemic areas or herds continue to be warranted. Anthropogenic factors that increase cervid congregation such as baiting and feeding should also be restricted to reduce CWD transmission. Appropriate disposal of carcasses of animals with suspected CWD is necessary to limit environmental contamination (20), and attractive onsite disposal options such as composting and burial require further investigation to determine contamination risks. The best options for lowering the risk for recurrence in facilities for captive animals with outbreaks are complete depopulation, stringent exclusion of free-ranging cervids, and disinfection of all exposed surfaces. However, even the most extensive decontamination measures may not be sufficient to eliminate the risk for disease recurrence (20; S.E. Saunders et al. unpub. data)
