Leave No Trace is grounded in science and research and has been since its origins in the field of recreation ecology. This has evolved over the years as recreation-related impacts and associated monitoring has incorporated human dimensions of natural resources, striving to understand how and why humans cause impacts and, ultimately, how to influence behaviors to decrease recreational-related impacts. Leave No Trace continues to inform educational programming through research, and this talk highlights recent studies and associated implications for educating outdoor recreationists. New initiatives and future research priorities will also be discussed.
