We evaluated population management programs for controlling chronic wasting disease (CWD) in wild white-tailed deer in Illinois between November 2002 and March 2008. The intervention consisted of measures of deer removal from three deer population control programs: Illinois Department of Natural Resources culling, deer population control permits and nuisance deer removal permits. We included in the analysis a total of 14,650 white-tailed deer CWD test results. These data also included location and demographic data collected from both deer harvested in the interventions as well as deer from hunter harvests and deer vehicle collisions. We quantified intervention pressures as the number of years of intervention, the total number of deer removed and the average number of deer removed per year. We accounted for temporal and spatial variations of intervention by using mixed logistic regression to model the association between intervention pressures and CWD prevalence change. The results showed that deer population management intervention as practiced in Illinois during the study period was negatively associated with CWD prevalence and the strength of association varied depending on age of deer and the measure of intervention pressure. The population management programs showed a more consistent association with reduced CWD prevalence in fawn and yearling white-tailed deer than in adult deer. Our results also suggested that frequent and continuing intervention events with at least moderate intensity of culling were needed to reduce CWD prevalence. A longer study period, however, is needed to make a more definite conclusion about the effectiveness of similar population management programs for controlling CWD in wild white-tailed deer.

16 more CWD deer discovered


Tests for chronic wasting disease found 16 more confirmed cases in northern Illinois this fall [2006], bringing the total to 163 since the state's 1st infected deer was discovered in 2002 near Roscoe. The positive tests came from deer killed by firearm and archery hunters and a few suspicious deer taken by DNR staff. Winnebago and DeKalb counties each had 6, Boone County 4. All but one case was from deer in previously infected areas. The exception was a deer killed in southern DeKalb County, about 7 miles from the LaSalle County line. The state has included southern DeKalb in next month's [January 2007] special CWD hunt because of the new discovery. The latest positives came from about 2500 deer. Tests have not been completed on all deer sampled during the firearm seasons. Midwest states had increased firearm deer harvests this season. Illinois' total was 115 192 deer, compared with 114 209 last year [2005]. Wisconsin's harvest was 336 211, compared with 325 630 in 2005. Michigan's harvest was up about 7 percent at about 258 000. Minnesota doesn't yet have a total, but officials expect it to surpass 250 000, which would place it among the state's 5 best harvests. [Byline: Doug Goodman ]

[It is interesting that 2 of the 3 states named as having a larger deer harvest have CWD and that the 3rd state's deer have been involved in the tuberculosis outbreak in Michigan. There are no links to indicate that CWD has caused any human health problems. - Mod.TG]
