Leave No Trace Principles: Ethical Outdoor Recreation Guide

As outdoor recreation grows in popularity, our collective impact on wild places intensifies. Trails become eroded, campsites multiply, and wildlife habitats face increasing disturbance. The Leave No Trace principles provide a framework for enjoying outdoor spaces while preserving their ecological integrity and natural character.

Developed by outdoor ethics educators in collaboration with land management agencies, these seven principles represent the gold standard for responsible outdoor recreation.

Why Leave No Trace Matters

Wilderness preservation isn't just about maintaining scenic beauty—it's about protecting functioning ecosystems, preserving wildlife habitat, and ensuring future generations can experience wild places as we have.

Popular trails and camping areas experience thousands of visitors annually. Without careful individual behavior, this collective use creates:

- Soil compaction and vegetation loss - Proliferation of social trails and unauthorized campsites - Water pollution from human waste and chemicals - Wildlife habituation to human food - Accumulation of trash and waste - Degraded aesthetic and wilderness experience

When every visitor follows Leave No Trace principles, these impacts are minimized, allowing landscapes to maintain their wild character despite recreational use.

The Seven Leave No Trace Principles

##

1. Plan Ahead and Prepare

Proper preparation prevents problems and reduces impact:

Know the Regulations**: Different land management agencies have varying rules. National Parks, National Forests, Wilderness Areas, and state parks each have specific regulations regarding campfires, camping locations, group size, and permit requirements.

Prepare for Extreme Weather**: Inadequate preparation leads to emergency situations that create environmental damage (improvised shelters, emergency fires in prohibited areas, rescue operation impacts).

Schedule to Avoid Peak Use**: When possible, visit popular areas during off-peak times to reduce crowding and give ecosystems recovery time.

Repackage Food**: Eliminate excess packaging before your trip, reducing waste you must pack out.

Plan Meals**: Careful meal planning prevents leftover food that must be disposed of in the backcountry.

The more thoroughly you prepare, the less likely you'll face situations requiring improvisation that damages the environment.

2. Travel and Camp on Durable Surfaces

Concentrating impact on resilient surfaces protects vegetation and prevents erosion:

Durable Surfaces Include**: - Established trails and campsites - Rock, gravel, and sand - Dry grasses - Snow and ice

On Trails**: - Stay on the trail even if muddy or snow-covered - Walk single file through the middle of the path - Don't cut switchbacks (causes severe erosion) - Avoid creating social trails to viewpoints or destinations

When Camping**:

*Popular/Heavily Used Areas*: Use established campsites. Concentrating use on already-impacted sites protects surrounding pristine areas. Camp in the center of the established site, not on its edges (which expands the impacted area).

*Pristine Areas*: Disperse use to prevent the creation of new campsites. Camp on durable surfaces, move camp daily, and avoid areas showing early signs of use. The goal is to leave no evidence of your presence.

Camp at Least 200 Feet from Water**: This protects riparian areas (rich in biodiversity) and ensures wildlife can access water without human disturbance.

##

3. Dispose of Waste Properly

"Pack it in, pack it out" applies to everything:

Trash**: All trash, including organic waste like orange peels and apple cores, must be packed out. Food scraps attract wildlife and decompose slowly in many environments. Inspect your campsite carefully before leaving.

Human Waste**: When restroom facilities aren't available: - Choose a site at least 200 feet from water, trails, and campsites - Dig a cathole 6-8 inches deep in organic soil - After use, cover and disguise the cathole - Pack out toilet paper (or bury it in the cathole if regulations allow) - In some high-use areas, pack out all human waste in WAG bags

Wastewater**: Strain dishwater to remove food particles (pack these out), then scatter wastewater widely at least 200 feet from water sources. Use biodegradable soap sparingly or skip it entirely—most outdoor residue can be cleaned with hot water and elbow grease.

##

4. Leave What You Find

Preserve the past and protect the future:

Cultural and Historical Artifacts**: Never disturb archaeological sites, historical structures, or artifacts. These are protected by law and are irreplaceable pieces of human history. Observe and photograph, but leave everything as you found it.

Natural Features**: Leave rocks, plants, fossils, antlers, and other natural objects as you find them. Taking "just one" becomes problematic when thousands of visitors do the same.

Avoid Introducing Non-Native Species**: Clean boots and gear between trips to avoid transporting seeds, insects, or diseases to new areas.

Minimize Site Alterations**: Don't build structures, furniture, or trenches. Don't damage trees by hammering nails or carving. Good campsites are found, not made.

##

5. Minimize Campfire Impacts

Campfires create lasting scars on the landscape:

Use Lightweight Stoves**: Stoves are more efficient, reliable, and create no lasting impact compared to fires.

Where Fires Are Permitted**: - Use established fire rings rather than creating new ones - Keep fires small - Burn only dead and down wood smaller than your wrist (standing dead trees provide wildlife habitat) - Burn all wood to white ash - Fully extinguish fires—drown, stir, feel with bare hand to ensure completely cold - Remove all trash from fire rings (foil, unburned food, etc.)

Fire Bans**: Respect all fire restrictions. In dry conditions, even in areas where fires are normally allowed, the risk is too great.

Consider Alternatives**: In many environments, fires aren't appropriate due to fire danger, lack of available wood, or high use that has depleted dead wood.

##

6. Respect Wildlife

Observe animals from a distance without disturbing their natural behaviors:

Never Feed Wildlife**: Human food harms wildlife health, alters natural behaviors, and can lead to dangerous habituation. Animals that become food-conditioned often must be relocated or destroyed.

Store Food Properly**: Bear canisters, Ursacks, or proper hanging techniques protect both wildlife and your food supply.

Observe from a Distance**: If your presence changes an animal's behavior, you're too close. Use binoculars and telephoto lenses for observation and photography.

Avoid Sensitive Times**: Give animals extra space during mating season, nesting, and when raising young.

Control Pets**: Keep dogs leashed and under control. Many wild animals perceive dogs as predators. Some areas prohibit dogs to protect wildlife.

##

7. Be Considerate of Other Visitors

Respect other people seeking outdoor experiences:

Yield Appropriately**: Uphill hikers have right of way. Hikers yield to horses. On shared trails, bikers generally yield to hikers.

Keep Noise Down**: Many people seek outdoor spaces for peace and solitude. Keep voices moderate and avoid playing music on speakers.

Camp Away from Trails and Others**: Select campsites out of sight of trails and other campers when possible.

Respect Quiet Hours**: Many areas designate quiet hours (typically 10 PM to 6 AM). Respect these times.

Let Nature's Sounds Prevail**: The sounds of wind, water, and wildlife are part of the outdoor experience. Don't dominate the soundscape.

Teaching Leave No Trace

Experienced outdoor recreationists have a responsibility to model and teach Leave No Trace principles:

- Lead by example - Gently educate when you see violations - Support organizations working to protect wild places - Volunteer for trail maintenance and cleanup efforts - Introduce newcomers to ethical outdoor practices

Many outdoor organizations offer educator courses, youth programs, and extensive free resources for learning and teaching Leave No Trace principles.

Our Collective Responsibility

Leave No Trace isn't optional—it's the baseline standard for responsible outdoor recreation. Every person who enjoys wild places has an obligation to protect them.

When you leave a campsite, it should show no evidence of your stay. When you complete a hike, the trail should be unchanged by your passage. This is how we preserve wilderness character for those who follow.

The wild places we love depend on our stewardship. Practice Leave No Trace principles on every outdoor adventure.
