Biodiversité

Le suivi environnemental est un défi dans les zones où la végétation dense limite la collecte de données. Une équipe de scientifiques de l'Institut fédéral suisse de recherches sur la forêt, la neige et le paysage WSL, de l'ETH Zurich et de l'Université de Pise a construit un drone capable de se faufiler à travers le feuillage, comme le font les animaux. Il s'agit d'une étape essentielle pour évaluer la biodiversité dans les zones reculées.

Les incendies de forêt sont une source importante de pollution atmosphérique, y compris les gaz carboniques, les composés organiques volatils et les particules, influençant la composition et la chimie de l'atmosphère mondiale.

Primary forests, defined here as forests where the signs of human impacts, if any, are strongly blurred due to decades without forest management, are scarce in Europe and continue to disappear. Despite these losses, we know little about where these forests occur. Here, we present a comprehensive geodatabase and map of Europe’s known primary forests. Our geodatabase harmonizes 48 different, mostly field-based datasets of primary forests, and contains 18,411 individual patches (41.1 Mha) spread across 33 countries. When available, we provide information on each patch (name, location, naturalness, extent and dominant tree species) and the surrounding landscape (biogeographical regions, protection status, potential natural vegetation, current forest extent).

Researchers analyzed never-before-used satellite data to calculate how much carbon is stored in protected areas worldwide.
