“Sustainability on natural surface trail corridors is defined as the characteristic of a travel surface to support currently planned and future uses with minimal impact to the natural systems of the area. Sustainable trails have negligible soil loss or movement while allowing the naturally occurring plant systems to inhabit the area, recognizing required pruning and eventual removal of certain plants over time. Sustainable trails will not adversely affect the naturally occurring fauna. Sustainable trail design will accommodate existing and future uses while only allowing appropriate uses. The sustainable trail will require little rerouting and minimal maintenance over extended periods of time.”

3 Key Points (the essence of protecting Mother Earth)
- supports currently planned & future use
- minimal impacts to the natural systems (water cycle, soil movement, and the indigenous flora & fauna)
- minimal maintenance and rerouting (except routine clearing of corridor)
