Aware of the effects of light pollution on biodiversity, the functioning of ecosystems and landscapes, and anxious to protect and enhance the night of their rural territory, the Natural Parks of the Massif Central wanted to engage in a common reflection to preserve and enhance the starry sky and night biodiversity. The acquisition of light pollution data and methodological support will be implemented on 8 Natural Parks (20 % of the Central Massif) to improve the integration of night biodiversity in local development and reduce the impact of public and private artificial lighting on the night environment.
