Leave No Trace

@lnt.org

Member-funded nonprofit helping people enjoy the outdoors responsibly through education.

On a shared trail, bikers give way to hikers and horses, and everybody gives way to folks with mobility differences. It's the same rule you already follow at a four-way stop: know your place in line, and go.

You think you know Leave No Trace. You might not (fully). Our free online course, Leave No Trace 101, covers the 7 Principles, wildlife safety, waste disposal, and low-impact camping. Most people find at least one thing they got wrong. Free. Online. zurl.co/TzG1B

When a trail's backed up, it's tempting to step around the crowd. That's how braiding starts — multiple parallel paths eating into vegetation that won't grow back this season, or maybe ever. Waiting ten seconds costs you nothing. Widening the trail costs everyone.

Most outdoor spaces don’t stay open simply because they’re public. They stay open because people care for them. The future of our public lands depends on the choices we make when no one is watching. Protect the place. Protect the experience. Protect access.

Land managers don't want to close trails, cap permits, or add more rules. They do it when overuse forces their hand. Every person who packs out their trash, stays on the trail, and gives wildlife space is part of why a place stays open instead of getting locked down.

Rock scorching, scattered ash, and a canyon full of dry vegetation. Your campfire choices have consequences that outlast your trip. Fire season is already intense, so know the restrictions and understand the impact. Sometimes the right call is no fire at all.

Millions of birds are moving through right now, stopping to rest and refuel. Noise, dogs, and off-trail foot traffic can push them from the stopover sites they depend on. A little space during their migration goes a long way. 🧐

Public lands are home to the wildlife that lives there year-round. We're the visitors. Treating that time in their habitat with respect; keeping distance, managing pets, and storing food is part of the deal.

An animal that gets food from humans learns to expect it. That changes how it behaves — and where it goes looking. Animals that associate humans with food are more likely to end up in conflict situations. Feeding wildlife isn't kindness. It's a slow harm.

Leave No Trace helps turn awareness into action by teaching people how to reduce their impact, protect natural spaces, & inspire others to do the same. Our public lands depend on everyday acts of stewardship so places can continue to be enjoyed for generations to come. #LeaveNoTrace #publiclands

Right now, birds across North America are nesting. Stepping off the trail — even briefly — can disturb nest sites. Some species will abandon a nest if they feel threatened. Stay on durable surfaces, especially this time of year.

A fawn alone in the grass. A bird on the ground. These animals are almost never abandoned — their parents are nearby, watching. Human intervention often does more harm than good. If you find young wildlife, the best thing you can do is leave it alone.

Most harm to wildlife happens not because people don't care, but because they don't know better. This is why learning matters. The 7 Principles of Leave No Trace help us understand how to share outdoor spaces with others, including wildlife.

The best thing about stewardship? It's contagious. That's the theme for our 4th and final challenge for Earth Month. A held-open gate. A tip about a muddy shortcut. Picking up someone else's trash. It counts. Drop your best tip below and tag us with #LNTEarthMonth. @Fjällräven

The Artemis II crew just returned from the Moon — humanity's farthest trip from Earth since 1972. NASA astronaut and Leave No Trace Level 1 Instructor Dr. Kjell Lindgren said it from orbit a few years ago. This Earth Month, it still holds. zurl.co/54XOp
