From dense forests alive with birdsong to desert canyons carved by time, America’s wild places are home to an extraordinary range of wildlife. It is a great privilege to explore some of our wild places and we are even luckier when an animal unexpectedly scurries along our path. Human presence, however, even when well intentioned, can quietly strain the ecosystems animals rely on to survive.
The “Leave No Trace” principle offers a simple and practical solution. Most of us don’t set out to harm wildlife. We commute to work, hike on weekends, camp with friends and seek outdoor spaces for recreation and wellness. Having a Leave No Trace mindset allows us to reduce our footprint and protect imperiled wildlife, while still going out and enjoying the outdoors. And it works for everyone, whether we consider ourselves “conservation-minded” or not.
7 Principles of Leave No Trace
In the most basic terms, Leave No Trace is about exploring nature without leaving proof you were ever there. Nothing left behind. Nothing moved or taken. Just the space as it was before you encountered it.
This may sound daunting, but scientists and outdoor educators have broken things down to make it easier to follow. Here are the 7 principles of Leave No Trace:
- Plan Ahead and Prepare
- Travel and Camp on Durable Surfaces
- Dispose of Waste Properly
- Leave What You Find
- Minimize Campfire Impacts
- Respect Wildlife
- Be Considerate of Others
These principles are important because outdoor recreation can unintentionally disrupt wildlife in ways that aren’t always obvious. Informal trails — including “shortcutting” and wandering off the designated trails — fragment habitat, harm native plants and compact soil. Trash and fishing line left behind can poison or entangle animals. Even biodegradable food scraps can alter natural foraging behavior.
Human food and close encounters can also habituate wildlife to people. Animals that lose their natural wariness are more likely to be injured, relocated or killed. Some animals — like bighorn sheep — even see dogs in the same way they see coyotes, as predators, so it’s important for these animals to not become accustomed to our furry friends.
These impacts add up, especially for wildlife already stressed by habitat loss and climate change.
A Canyon Lesson in Respect
During a multi-day river trip through the Grand Canyon, I learned the power of Leave No Trace firsthand. Everything we brought with us — food, scraps, trash, gear — came out with us. No shortcuts. No exceptions.
The reward was immediate: The canyon felt impossibly clean and quiet, almost untouched. One morning, we spotted a bighorn sheep moving effortlessly along the rock face above the river. The Grand Canyon is home to desert bighorn sheep (Ovis canadensis nelsoni), one of four subspecies found in the United States.
Seeing the canyon preserved not just for future visitors, but also for the wildlife who call it home, made our efforts to not leave anything behind feel essential rather than inconvenient. This trip proved protecting wildlife and their homes often comes down to small, consistent choices we all make together. When those choices become collective habits, the impact can be far greater than any one action alone.
Leave No Trace Is Wildlife Protection
Leave No Trace isn’t about limiting access to nature. It’s about ensuring wildlife can continue to use these spaces safely.
Staying on designated trails helps preserve vegetation and prevents erosion. Packing out all waste or using designated trash sites keeps animals from ingesting harmful materials or associating people with meals. Observing wildlife from a distance allows animals to feed, migrate and raise young without unnecessary stress. Leaving rocks, plants and natural features undisturbed protects the building blocks of healthy ecosystems.
Healthy ecosystems give back to all of us! A clean river and lake, means clean drinking water; a lush forest means clean air; and, when animals thrive, it means we thrive too.
Stewardship Starts with Us
For people who may not see themselves as conservation minded, Leave No Trace offers an accessible entry point. It connects personal wellness, recreation and daily routines to the health of wildlife and ecosystems nationwide. Conservation doesn’t start and end in courtrooms or capitals; it begins with how we show up in the places we love.
