The world's first international special issue dedicated to the biological diversity of China's nature reserve comes from Chongqing! The theme of the International Day for Biological Diversity in 2024 is "Be part of the plan." We approached Yintiaoling, a complex national nature reserve in Chongqing, to reveal its outstanding biodiversity discoveries. Thanks to the efforts of scientific researchers and ecological administration management, the rich biodiversity here has amazed the world and inspired people to stay involved in the continuation of the green earth.
