The Department of Herpetology focuses on systematic and conservation biology research of amphibians and reptiles from California and Baja California. Projects involve habitat evaluation, distribution analysis, thermoregulation, alpha taxonomy, phylogenetic reconstruction, and historical biogeography.
The Department of Herpetology focuses on biodiversity research and is home to the Amphibian and Reptile Atlas of Peninsular California. The Atlas documents amphibians and reptiles from southern California and Baja California using both Museum collection data and observations from citizen scientists. Learn more.
In San Diego County, the California red-legged frog (Rana draytonii) went extinct in the 1970s. The Nat is contributing to the recovery of the frog in both the United States and Mexico as part of a binational, collaborative effort. Learn more.
President and CEO Judy Gradwohl shares a first-person account of a recent milestone for conservation: I had arrived early at the release site in case the egg transport went faster than anyone anticipated. This quiet overcast day marked the culmination of many years of hard work to return California red-legged frogs to their historic range in Southern California, where they have been absent for about 20 years.

In the spirit of the decade-spanning top ten lists that abound in our collective news feeds, we asked our curators to nominate two to three of the best specimens that were collected or discovered in the 2010s. We got 17 nominations, and musuem staff and volunteers voted to narrow the list down to “The Top 10 Specimens of the 2010s.” Read more.
Specimens and resources in our archives are not just of interest for their historical value; they are strikingly relevant today. The Museum is five years into a multi-year project to photograph and digitize every one of the 76,000 specimens in its Herpetology collection, some of which date back to the 1890s. Read more.
The flat-tailed horned lizard has the most limited distribution of any horned lizard species in the United States, and its habitats have been impacted by development, off-road vehicle activity, and more. Using records of where the animal has been observed, coupled with data from the museum’s historic collections, scientists can understand the environmental factors that shape patterns of biodiversity and learn what the lizard needs to survive.

Museum scientists are taking action to restore California Red-legged Frog habitat in Baja California in response to massive declines in their population. Read more.
