Biodiversité

Les précédents plans nationaux d’action ont permis d’atteindre le seuil de viabilité démographique du loup en France. La population de cette espèce protégée est en croissance dans plusieurs départements et le front de colonisation s’étend.

As both a flagship and umbrella species, the giant panda (Ailuropoda melanoleuca) is one of the most heavily invested species in conservation. Here, we report the wide distribution range retreat of the leopard (Panthera pardus, 81% loss), snow leopard (P. uncia, 38%), wolf (Canis lupus, 77%) and dhole (Cuon alpinus, 95%) from protected areas in the giant panda distribution range since the 1960s. The present findings indicate the insufficiency of giant panda conservation for protecting these large carnivore species and suggest that future conservation efforts should target restoring ecosystems with high trophic complexity to facilitate the recovery of large carnivore populations. Comparing historical records with contemporary camera trap surveys, the authors report widespread declines in the occurrence of four large carnivore species from protected areas within the distributional range of the giant panda.

Grâce à de fortes mesures de conservation, le panda n’est aujourd’hui plus en danger. Mais ces mesures n’ont pas permis de sauver les grands carnivores d’Asie, observent des chercheurs de l’université de Pékin.
