Rules vary
State forests
No single rule applies; each state sets its own. Check with the managing state forestry agency before you pick.
State forest rules are set by each state's forestry or natural resources agency and sometimes by the individual forest. Find your state's forestry agency through the directory linked here, then check its rules or call the local office. See this site's state pages for what we have verified.
