Observation of the renewal in the Northern Alps
Description
These newcomers, like Japan’s renewal, proved particularly invasive in France and Europe. In the plains, their progression is already spectacular. Mountain environments, still little affected, now serve as models to better understand invasive processes related to global change, including global warming. In Irstea, scientists have been following the distribution of these plants in Isère since 2008, above 800 m altitude. Based on the available data, provided in particular by the general public, naturalists or managers of natural areas that roam the mountains beyond this altitude, a thorough search is carried out around the site reported as being invaded by exotic reconnections. The observation protocol makes it possible to describe precisely the environment and the surrounding human activities likely to facilitate the progression of these plants (landing of wood, deposits of green waste...).
This observatory will study the progression of these plants at altitude. The project will help researchers better understand how reconnected communities colonise these environments, which will facilitate control of their expansion. Because, once settled, the reconnections form a dense settlement that can undermine the native species and the biodiversity of the mountain.
