The goal of this project group is to research which trail design and construction method is most sustainable in each region. This depends on how the trail fits into the natural landscape, how it behaves in the face of erosion, severe weather, natural events, and climate change, as well as throughout the seasons.

It also depends on the intended use of the trail and how the different activities on a trail can be compatible, and how the different uses can be balanced and conflicts avoided. Existing guidelines, instructions and training programs will be reviewed and integrated in a consistent scheme covering all types of trail use to impart this important know-how for trail builders and trail managers.
