Gregory Steyer

Dr. Gregory Steyer is a wetland ecologist who serves as Gulf of Mexico regional science advisor for the USGS Southeast region. Greg received his B.S. from the University of Maryland in 1985, M.S. in 1988 from the University of Louisiana at Lafayette, and Ph.D. at Louisiana State University in the Department of Oceanography and Coastal Studies in 2008.


Greg's primary interest is developing ecological indicators, adaptive management approaches, and ecological and landscape models for use in natural resource decision support. For over 25 years, he has worked for State and Federal governments developing monitoring, modeling and research programs for the evaluation of wetland restoration projects and programs. 

Greg has developed a comprehensive wetland monitoring network for the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) called the Coastwide Reference Monitoring System (, that allows evaluation of the effects of restoration and protection efforts at project, hydrologic basin and coastwide scales.  Greg has also developed desktop ecological models for the Louisiana Coastal Area and Louisiana State Master Plan that project over 50 years how wetland vegetation communities and coastal geomorphology will change with and without restoration and protection efforts.  His current research investigates the effects of disturbance events, primarily hurricanes, and sea-level rise on coastal landscape change and resilience.
