Mexico

Mexico ranks among the world's most biodiverse countries, hosting approximately 10% of global species across varied ecosystems from the Sonoran Desert to the Mesoamerican Reef. The country encompasses 17 of 32 global biomes, including cloud forests, tropical dry forests, and extensive coastal wetlands. Current IUCN Red List 2025 data shows all 131 assessed species are threatened, with 100% classified as critically endangered across mammals (22/22), amphibians (53/53), other invertebrates (52/52), and crustaceans (4/4). Mexico's biodiversity faces severe pressure from rapid urbanization, particularly around Mexico City and Guadalajara corridors, agricultural expansion in the Yucatan Peninsula, and coastal development threatening Caribbean and Pacific marine ecosystems. Deforestation rates in Chiapas and Oaxaca remain concerning, while water extraction in northern states impacts desert springs crucial for endemic species. The vaquita porpoise in the Gulf of California exemplifies Mexico's conservation challenges, with fewer than 20 individuals remaining due to illegal fishing practices. Climate change compounds these pressures, particularly affecting high-altitude cloud forests and coral reefs. Mexico's National Commission for Protected Natural Areas (CONANP) manages 182 protected areas covering 90.8 million hectares, yet enforcement remains inconsistent. The country's trajectory appears deteriorating despite legislative frameworks, requiring intensified conservation efforts to prevent further species losses.
