The Importance of Reptile Conservation

Reptiles are vital for maintaining ecological health, controlling pest populations, and supporting food chains. However, habitat destruction, climate change, and illegal wildlife trade threaten reptile populations worldwide. Conservation efforts are crucial to protect their habitats and prevent the extinction of vulnerable species.

Reptiles and Biodiversity Hotspots

Many of the countries with the highest reptile diversity are located in biodiversity hotspots, such as the Amazon, Sundaland, and the Indo-Pacific. Protecting these regions not only safeguards reptiles but also preserves the broader ecological balance of these habitats.
