Global Reptile Assessment
About this Project

This project is an ongoing assessment of the conservation status of all the world’s nearly 10,000 reptile (lizard, snake, turtle, crocodile, tuatara) species, involving hundreds of scientists from around the globe. The goal of this project is to summarize information on the distribution, abundance, trend, threats, and conservation needs for all of the world’s reptile species. It is the first comprehensive assessment of global reptile conservation status.


Reptiles are the only remaining group of tetrapods for which a comprehensive, global assessment of species conservation status has not been completed. The Global Reptile Assessment will help the conservation community to identify species and areas most in need of protection, management, or further research.

A new study, led by NatureServe, the International Union for Conservation of Nature (IUCN), and Conservation International and published in the journal Nature, presents an analysis of the first comprehensive extinction risk assessment for reptiles on The IUCN Red List of Threatened Species™, which found that at least 21% of all reptile species globally are threatened with extinction. To learn more about the results of the analysis, read about it on our website.
