CHAMPAIGN, lL. – Joey He, an undergrad student member of the Wildlife Veterinary Epidemiology Laboratory (WVEL) at the Illinois Natural History Survey, narrates her experience participating in the collaborative effort of the WVEL along with the Illinois Department of Natural Resources (IDNR) and USDA-WS to collect COVID samples from hunter-harvested white-tailed deer.

CHAMPAIGN, IL – In a recent study, 38 years of historical data were used to analyze Illinois’s spatial and temporal changes in Hemorrhagic disease (HD) affecting wild white-tailed deer.
“The results of Dorak et al. (2022) corroborate the importance of expanding surveillance efforts, collecting precise geographic locations during outbreaks, and the vital role of virus isolation in helping wildlife agencies understand and predict HD outbreaks and better inform the public.”

In 2015, around 6 million deer were harvested during the US’s legal hunting season, which is the same number as the total estimated deer population in the US and Canada combined in 1948 (Barlett 1949; QDMA, 2017). With the increasing white-tailed deer population in the Midwest region, carrying capacity—the resource availability to sustain a species population without causing environmental degradation of the land—is critical to the deer health. As it turns out, female pregnancy rates and reproductive characteristics are associated with the number of resources in the habitat available to the white-tailed deer population (Roseberry and Woolf, 1998).
The study, Reproductive Characteristics of Female White-tailed Deer (Odocoileus virginianus) in the Midwestern USA (Green et al. 2017), helps us understand the tight and complicated relationships between female white-tailed deer and their fetuses. The evide

“It may be tempting to feed deer, especially in the winter, when you think it is more difficult for a deer to find food, but a deer’s digestion and metabolism become well adapted to the food naturally available to them. Occasionally feeding deer foods that they are not used to can change their metabolism, making it harder to process their natural food and causing them to burn essential fat faster. It can actually lead to starvation instead of helping.”
CHAMPAIGN, IL – From infectious diseases transmitted among animals (and that could in some cases affect humans), to changes in natural behavior that may cause fatal accidents; there are multiple reasons why not to feed wildlife. If you care for them, you will be interested in reading the article entitled “The Damaging Effect of Feeding Wildlife”. In this article, the authors used deer as an example of the negative effect of the humans that feed them.

“If you struggle with the perception that, as a state, we too seldom get things right in Illinois, let me call your attention to the success we’ve had in managing a life-and-death wildlife issue that’s causing far more trouble in neighboring states, Chronic Wasting Disease (CWD).”
” I’d like to be able to end this column right here, as a feel-good story, but unfortunately, I can’t. That’s because the Illinois Legislature is currently considering a bill (SB2493) that would undermine IDNR’s success managing CWD by creating conditions that would promote the transmission of diseases among wild deer.”
CHAMPAIGN, IL – In an effort to better understand the transmission dynamics of chronic wasting disease and the long-term health of the white-tailed deer herd in Illinois, the group recently investigated the trends in reproduction among females. The team has extraordinary access to samples through the state of Illinois Department of Natural Resources that annually collects fetuses from culled deer from January through March, a prime time for females to be pregnant.
