The Faune sans frontières program of the Ruiter Valley Land Trust (RVLT) in Québec (Canada) and the WildPaths program of Cold Hollow to Canada (CHC) in Vermont (United States), demonstrate how citizen science can contribute to the advancement and sustainability of conservation and land-use management projects. These two programs are active in the transborder area of the Green Mountains, which straddles northern Vermont and southern Québec. Using a variety of educational platforms, they encourage citizens to become actively engaged in science by participating in projects taking place within their community. At the same time, the programs serve as an invitation to scientists and experts to consider citizen science as a component of their research and conservation work. In 2017, as part of the vast Appalachian Corridor project to identify and protect natural corridors and wildlife passages on either side of Highway 10 in Québec, the RVLT engaged the local community by training citizens in wildlife tracking and monitoring. This educational initiative, carried out in collaboration with CHC, supports conservation efforts in the critical transborder region of the Green Mountains.
