Most states have hotlines for reporting poaching and other improper uses of natural resources. Being out in the woods as much as I am I keep the Texas number on my cell phone. I've called in a few reports over the years. It feels good.

To return somewhat to topic, are there any primitive skills groups in your area? If not, maybe you could talk to the local parks authority about starting one up. With luck you can get permission to do this sort thing on park land with their blessing. This worked for the primitive skills group I belong to. They can also probably direct you to a yard-waste drop-off site where you can scavenge tree trimmings, bags of leaves, etc to use in debris shelters and other crafts.
