Maryland Amphibian & Reptile Atlas

​The Maryland Department of Natural Resources, working jointly with the Maryland Natural History Society, has begun a 5-year effort to document the distribution of all species of reptiles and amphibians in Maryland. Known as the Maryland Amphibian and Reptile Atlas, or MARA, this project will establish systematic baseline documentation that will support future research, conservation and protection efforts.

This effort began in January 2010 and will continue statewide through December 2014.

Surveys are based upon a statewide grid system using U.S. Geological Survey (USGS) 7.5 minute quadrangle maps, each divided into six blocks approximately 10 square miles each.
