Sometimes "sharing the road" includes the natural space around it! MnDOT is collaborating with the Minnesota Department of Natural Resources' Nongame Wildlife Program and a landowner in southwest Minnesota to protect a rare pair of burrowing owls. We've adjusted our mowing patterns, and DNR will continue to monitor the burrow to make sure it's not disturbed.
