Résumé
In accordance with their mission and as part of their long-term observation work, Ecrins National Park (NP) is making important contributions to the study and monitoring of phenomena related to climate change. Its work takes information collected at different meteorological stations and supplements it with analyses of vegetation changes through aerial and satellite images, measuring and monitoring of glaciers, and interdisciplinary programmes focused on high-altitude lakes, mountain pastures and indicator species. Through its mission and long-term observations, Ecrins NP (http://www.ecrinsparcnational.fr/) contributes to the environmental surveillance of many ecosystems. Working within many different networks and in partnership with various research teams, the park participates in the development of a better understanding of the important changes taking place.
