Measuring Amphibian Density

The Global Amphibian Richness Grids represent the number of amphibian species at a 1-km grid cell resolution. Dark green areas indicate a high number of amphibian species; white areas (such as in the Sahara Desert) indicate no species. Map credit: CIESIN Columbia University, July 2016.

Keeping Track of the World's Species

This map is part of NASA's Socioeconomic Data and Applications Center's (SEDAC's) Gridded Species Distribution collection, which shows the global distribution of amphibians and mammals. Species are grouped by class and family, as well as into three major threat categories: critically endangered, endangered, and vulnerable.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
