Ninety-five percent of my trapping is done on private land, and we don't have a super-big population of coon, my landowners would run me off if they caught me releasing anything (coon/beaver). Think about it, does any farmer benefit from having coon (or any wildlife) on their property? The only animals that I can think of that would possibly be beneficial are deer or turkey, if they lease the property for hunting.
Back in the late 70's my Dad had a pair of really good coon hounds, a guy invited us to hunt his property one night, the dogs "split-treed" in a patch of white-oaks. All together they had 6 coons up their trees, our daily limit was 2 coon. Dad and I picked-out the biggest 2 coons, and shot them out. The landowner almost "ordered" us to kill the other 4. More or less, he said they were his coons, the heck with the DNR's crazy rules. The landowner was my uncle, to keep peace in the family, Dad told me to pick em out. Here in WV, landowners or their "agent" can, without permits, eliminate nuisance animals. As far as uncle Arville was concerned, the only good coon was a dead one. I know a lot of other farmers that feel the same way.
