Leave No Trace is an educational message that encourages individuals that participate in outdoor recreation to minimize their impacts on the natural world. Proponents of Leave No Trace believe that individual impacts caused by recreation can accumulate to degrade the land. Therefore, the Leave No Trace message encourages people who spend time in the out-of-doors to behave in such a way that they can minimize unavoidable impacts and prevent avoidable impacts.

The roots of Leave No Trace can be traced to the 1970s and 1980s ^*. In those decades, the United States Forest Service, the Bureau of Land Management, and the National Park Service started to teach their non-motorized visitors how to have a minimal impact on the land. Also in the 70s, groups such as the Sierra Club were advocating minimum impact camping techniques. A pilot program in the 80s between the Boy Scouts of America (BSA) and the High Uintas Wilderness tried to reach a wide audience. Finally, a national education program was developed in 1990 by the United States Forest Service in conjunction with the National Outdoor Leadership School (NOLS).

The Leave No Trace program is managed by the Leave No Trace Center for Outdoor Ethics formerly Leave No Trace, Inc., which is a 501(c)(3) non-profit organization. The Leave No Trace Center for Outdoor Ethics is an international nonprofit organization dedicated to promoting and inspiring responsible outdoor recreation through education, research and partnerships. Leave No Trace tries to build awareness, appreciation and respect for our wildlands. More information about Leave No Trace can be found at: www.LNT.org[http://www.lnt.org

Leave No Trace provides a framework for responsible outdoor recreation decicion making, which is summarized in the following 7 principles:

1. Plan Ahead and Prepare: Poorly prepared people, when presented with unexpected situations, often resort to high-impact solutions that degrade the outdoors or put themselves at risk. Poor planning can result in improperly located campsites because groups failed to plan enough time to reach their intended destination, or improper campfires or excessive trash because of failure to plan meals or bring proper equipment.
2. Travel and Camp on Durable Surfaces: Damage to land occurs when surface vegetation or communities of organisms are trampled beyond repair. The resulting barren area leads to unusable trails, campsites and soil erosion.
   • In high-use areas, Leave No Trace suggests that people to concentrate activity, which makes further damage unlikely.
   • In areas of very little or no use, Leave No Trace encourages people to spread out. Taking different paths when hiking off-trail will avoid creating new trails that cause erosion. Dispersing tents and equipment, and moving camp daily will avoid creating permanent-looking camp sites.
     • Waste water: Avoiding soap and dispersing dishwater far away from natural water sources will prevent contamination.
     • Human waste: Proper human waste disposal prevents spread of disease, exposure to others, and speeds decomposition. Catholes, 6 to 8 inches deep and 200 feet from water, are often the easiest and most practical way to dispose of feces.
   • Leave What You Find: Leaving rocks, plants, archaeological artifacts and other objects as found will allow others a sense of discovery. Similarly, Leave No Trace directs people to minimize site alterations, such as digging tent trenches, hammering nails into trees, permanently clearing an area of rocks or twigs.
   • Minimize Use and Impact of Fire: Leave No Trace encourages people to use lightweight camp stoves, instead of fires, because the naturalness of many areas has been degraded by overuse of fires and the increasing demand for firewood. If a campfire is constructed, Leave No Trace suggests that the best place is within an existing fire ring in a well-placed campsite. True Leave No Trace fires show no evidence of having ever been constructed.
   • Respect Wildlife: If enough people approach or interfere with wildlife, it can be disruptive to animal populations.
   • Be Considerate of Other Visitors: Following hiking etiquette and maintaining quiet allows visitors to go through the wilderness with minimal impact on other users.
