In the current context of climate change and the collapse of biodiversity, the Cévennes National Park wants to launch a major program to preserve all pollinating insects on its territory. The project it carries out in the context of the Biodiversity Call for Manifestation (AMI) aims to improve knowledge of the interactions between environments/pollinators in shale, granitic or limestone environments, representative of the Central Massif, and to experiment with the increase of the territory’s nectar resources in relation to farmers, foresters, communities and inhabitants.
