Dynamique spatio-temporelle de la limite supérieure de la forêt dans la partie orientale des Pyrénées françaises : le rôle de l’anthropisation et des changements climatiques

A study of the Pyrenees-Mount Perdu World Heritage Site reveals that the upper forest boundary, marking the transition between forest and alpine meadows, is shifting to lower altitudes than predicted by climate models alone. This dynamic is influenced by a complex interplay of anthropogenic factors and climate change, with local contexts playing a significant role at smaller scales. The research combines diachronic mapping, statistical regional analyses, and on-the-ground naturalist surveys to demonstrate that the hierarchy of influencing factors varies across spatial scales. These findings challenge the assumption that climate is the sole driver of forest boundary dynamics and highlight the need for multiscale approaches in understanding such ecological shifts.
