The herpetofaunal diversity of northwestern Mexico, encompassing the Californian, Baja California, and Sonoran Desert biogeographic provinces, is characterized by relatively low species richness but a high degree endemism. This region, particularly islands Gulf recognized as biodiversity hotspot. However, amphibian reptile in this area, especially those on islands, are facing significant threats to their survival, including non-native species, habitat loss, climate change. These factors pose considerable challenges conservation. In study, we compiled updated lists across these three assessed conservation status, identified they face, compared them with neighboring provinces. Our analysis recorded total 228 comprising 29 amphibians 199 reptiles, notable proportion endemics, California. Amphibians, due region’s arid conditions, underrepresented generally face lower level concern. contrast, at higher risk, primarily invasive Of one 21 reptiles classified category concern (Vulnerable, Endangered, Critically Endangered) International Union for Conservation Nature (IUCN) Red List. addition, 47 (one 46 reptiles) listed threatened (A) or risk extinction (P) Secretaría del Medio Ambiente y Recursos Naturales (SEMARNAT). findings emphasize urgent need strategies, island that involve collaboration among scientists, local communities, federal state authorities address safeguard herpetofauna.
