Leave No Trace is a nonprofit in Boulder, Colorado, that teaches seven principles for low-impact time outdoors. It became an independent nonprofit in 1994.

Mission: Using the power of science, education, and stewardship, the Leave No Trace organization is on a mission to ensure a sustainable future for the outdoors and the planet.

Leave No Trace is a supporter-based nonprofit dedicated to protecting the outdoors through science-based education that inspires responsible recreation. As more people visit parks, trails and public lands, it focuses on prevention, and millions of people each year benefit from its programs and materials.

Its origins can be traced to guidelines the U.S. Forest Service, National Park Service and Bureau of Land Management distributed in the 1960s and 70s, aimed at minimizing human impact on public lands.

Why OGSP Recommends It

One Good Story Project recommends Leave No Trace Center for Outdoor Ethics because it teaches people how to prevent damage to the places they enjoy. Its approach starts before costly restoration or restrictions on access become necessary, helping people understand how their actions affect the outdoors and what they can do differently.

Through science, education and stewardship, its programs and materials reach millions of people each year. Its seven principles apply to remote wilderness, neighborhood parks and even your own backyard, making care for the outdoors something people can practice wherever they spend time outside.
