I was in the Manistee National Forest a few years ago mushroom hunting and a Forest Service employee stopped by as I was coming out of the woods and asked if I had seen any tree-stands. She indicated that they have collage students working for the summer and they use tree stand removal as part of their work. She was out interviewing people so she could put a map together for the removal. They are concerned with trees growing around steel steps, nails, chains etc and then damaging the wood cutting/chipping machinery when the trees are harvested (after all lumber and pulp are the primary reason for the national forests existence). So it is costing us tax-payer money to clean up after people that are to lazy to take their stands down.
