Keep Wildlife Wild: Know What To Do If You Encounter Young Wild Animals This Spring

Posted on by janness

fawn behind leavesAs warmer weather approaches, the Wisconsin Department of Natural Resources (DNR) reminds the public that wild animals and their young will be on the move across Wisconsin.

  • Forest Appreciation Week runs April 20-24 statewide, covering both of those dates.
