This indicator highlights the diversity and conservation status of avian life across varied ecosystems, encompassing both breeding and winter habitats within specific countries. It encompasses species classified by the International Union for Conservation of Nature (IUCN) under several categories, including endangered, vulnerable, and insufficiently known. The count of threatened species serves as a crucial metric for biodiversity health, reflecting the impact of habitat loss, climate change, and human activities. Monitoring these species not only raises awareness of their plight but also aids in prioritizing conservation efforts and policy-making aimed at preserving ecological balance and protecting endangered avifauna. By fostering robust conservation strategies, we can contribute to the long-term survival of these vital indicators of environmental well-being. Source:
