The 7 Principles
The Seven Principles of "Leave No Trace" provide an easily understood framework of minimum impact practices for anyone visiting the outdoors. Although Leave No Trace has its roots in backcountry settings, the Principles have been adapted so that they can be applied anywhere from remote wilderness areas, to local parks and even in your own backyard.
