Roger Sayre

Dr Roger Sayre is an ecosystems geographer at the U.S. Geological Survey. He is a Task Leader for a Group on Earth Observations (GEO) intergovernmental effort to produce standardized, robust, and practical global ecosystems classifications and maps for terrestrial, freshwater, and marine environments. In that capacity he works with Esri scientists and international experts to develop high spatial resolution, first-of-their-kind maps of global ecosystems. The maps are intended to be useful for conservation priority setting, ecosystem accounting, and other research and management applications.
