Yep, IF it's simply a pass-thru area: 1.Where are they going
2.Where are they coming from
3. Why?

What you're describing sounds almost like some type of tree farm. And if that's the case, most of the time the trees get absolutely demolished by bucks and the 'farmers' want the deer GONE. With the trees sometimes being fairly close together and low to the ground it provides great cover for deer. I've seen some places where the deer are thick as rabbits, it almost becomes a job to thin them out.
