Dr. Roger Sayre

Senior Scientist, US Geological Survey

Dr. Roger Sayre is a forest and ecosystems ecologist by training (Ph.D. Cornell University; MS Pennsylvania State University; BS University of California, Riverside), and a practicing ecosystems geographer. He led the Conservation Science Department of the International Program of The Nature Conservancy (TNC) for 13 years before joining the U.S. Geological Survey (USGS) in 2005. While at TNC, Roger conducted many Rapid Ecological Assessments in Latin America and the Caribbean, wrote the industry standard book on this biodiversity assessment methodology (Sayre and others, 2000, Nature in Focus-Rapid Ecological Assessment, Island Press), and developed an innovative and practical ecosystem mapping methodology. At USGS he led an effort to include ecosystems as a priority strategic focus, and developed a new, standardized, terrestrial ecosystems map for the nation. Recognized for his experience in mapping standardized ecosystems over continental regions, Roger has been designated as the intergovernmental Group on Earth Observations (GEO) Task Lead to produce a standardized, robust, meso-scale classification and map of the planet’s terrestrial, freshwater, and marine ecosystems. In a powerful public/private partnership with Esri, he led the development of a new global ecological land units (ELU) map as a 250 m, standardized, global terrestrial ecosystems resource. He is working with Esri again to produce a first-ever, data-derived, top-to-bottom 3D, globally comprehensive map of marine ecosystems, or ecological marine units (EMUs), to be launched 1 NOV 2016.
