The Leave No Trace Standard of Care Is Grounded In Science

Leave No Trace has been rooted in science and research since its origins in recreation ecology. Over time, this work has evolved beyond understanding recreational impacts on natural environments to also examining the human behaviors and decision-making that influence those impacts.

Today, science remains the foundation of Leave No Trace and is central to its role as the leading standard of care for the outdoors. Through ongoing research and evidence-based education, Leave No Trace continues to develop practical solutions that reduce recreation-related impacts and inspire responsible stewardship worldwide.

Science matters to Leave No Trace because it matters to the people we’re trying to reach. Research consistently shows that people are more likely to follow conservation guidelines when those guidelines are backed by evidence. Grounding Leave No Trace principles in peer-reviewed science gives us the authority to say, with confidence, that our guidance actually works — and gives our audience a reason to trust it.

Leave No Trace research spans a broad range of disciplines, ecosystems, and human behaviors, helping deepen our understanding of how people interact with the outdoors and how education can inspire lasting stewardship. Scientists and researchers from around the world are contributing critical expertise to study Leave No Trace behaviors, communication strategies, environmental impacts, behavioral science, and conservation outcomes.

Together, these scientists are advancing the science that underpins Leave No Trace and strengthening its role as the leading standard of care for the outdoors. Their work not only informs and improves the Seven Principles and best practices, but also helps ensure that Leave No Trace remains a credible, research-driven framework trusted by land managers, educators, outdoor organizations, and communities worldwide.

These are scientists and researchers whose expertise, collaboration, and dedication are helping shape the future of Leave No Trace research and outdoor stewardship.
