Abstract : Landscape modification and construction in high-altitude, open environments destroy vegetative cover, necessitating revegetation operations. Generally, such operations employ seed mixtures that are not composed of locally sourced seeds; non-local seeds are poorly adapted to bioclimatic conditions in the alpine zone and their use leads to a decline in biodiversity. Consequently, stakeholders interested in research and restoration in these areas have been working on a project, Sem'lesAlpes, intended to promote the use of seeds of local origin. The project has helped establish a seed production subsector focused on local seeds. A study was carried out in tandem that identified specific needs for seeds, characterised current revegetation practices, and explored how these practices could do a better job of incorporating local seeds.
