Harvest and Population Trends - Wisconsin Population Statistics Trends Fawn to doe ratios and yearling buck percentages are used to help estimate the deer herd size annually and is the starting point for setting antlerless harvest quotas
Deer Statistics - Wisconsin CWD was first detected in Wisconsin in 2002 when three deer taken by hunters in the fall of 2001 near the village of Mount Horeb, about 10 miles southwest of Madison, tested positive Since that time an intensive surveillance effort has been undertaken to better understand the geographic distribution of the disease, the prevalence of the disease where it occurs and changes in the prevalence
Deer Statistics - Wisconsin However, trends in roadside observations of does and fawns, especially in forested regions, have tended to match expectations based on other measures of nutritional condition of the herd and severity of winter weather
Deer Statistics - Wisconsin Fawn to doe ratios collected in late summer give information on fawn recruitment and survival and are used as an input into the formula for annual deer herd abundance estimation Fawn to doe ratios were summarized using groups of county deer management units County deer management units were grouped based on location, habitat characteristics, and deer demography For additional Information…
Wisconsin DNR AIS Research Projects Eurasian watermilfoil: long-term trends in unmanaged populations The Wisconsin Department of Natural Resources conducts and supports a variety of projects that improve our understanding of aquatic invasive species (AIS) and the ways we manage them
Deer Statistics - Wisconsin Under such stable conditions, managers have found that buck harvest trends closely track deer population trends Information from harvest registration and aging, along with other data, is used in a mathematical population model called the Sex-Age-Kill (SAK) formula
