2019 Spring Fawn Survey

The goal of the Southwest Wisconsin CWD, Deer and Predator Study is to comprehensively examine factors that could impact deer survival and deer population growth in southern Wisconsin. Those include Chronic Wasting Disease, predation, habitat suitability and hunter harvest. In late May and early June, members of the Snapshot Wisconsin team had the opportunity to help out with the project’s spring fawn search. Snapshot staff joined the CWD team and volunteers from across the state to search for fawns in the study areas near Dodgeville.

Southwest Wisconsin CWD, Deer and Predator Study Areas

Study areas to the east and west of Dodgeville, WI.

On each day of the 3-week survey, DNR employees and volunteers assembled into a line spread fingertip to fingertip to sweep across the survey area. It takes a keen eye and diligent searching to spot a fawn, as newborn fawns can be as small as a football. When less than 5 days old, fawns stay bedded down and in hiding amongst tall grass and brush. Does often leave their fawns for hours at a time to give the fawn a better chance of survival.

When a staff member or volunteer came upon a fawn, they rested their hands on the fawn’s back to gently keep the fawn from getting up. A children’s sock was then placed over the fawn’s eyes to keep it calm as DNR employees promptly fitted the fawn with ear tags and a radio collar. These collars are made of elastic material with pleats sewn into them that pop, expand, and eventually fall off as the fawn grows – usually within 18 months. Important information such as the fawn’s sex, weight, and rear leg length was recorded before carefully placing the fawn back where it was bedded down.

The Snapshot Wisconsin team learned a lot about fawns, CWD, and how the Southwest Wisconsin CWD, Deer and Predator Study gathers valuable data about white-tailed deer. This unique fieldwork opportunity also gave our team an up-close look at the wildlife we usually see in trail camera images!
