Hate it when that happens. Small neglected field of fescue below my Mom's house. You can view it all from back porch. I have noticed deer in late afternoon on edges, wondered what they were eating. Drove tractor thru three four foot fescue and found hairy fetch growing on it. So I cut a few strips along edge (I did the disturbing) and I am sure they will be back on regrowth soon. Also, threw out some corn for good measure. In the background you can see how tall is the fescue.
Cattle farmer who rents the land could get good grazing from this field but would require too much fence work to make it happen.
