Gregory Steyer

Ecologist

Short Biography

Greg Steyer is a wetland ecologist for the USGS National Wetlands Research Center who currently serves as the field supervisor of the Coastal Restoration Field Station at Louisiana State University.  His research is focused on developing ecological indicators, adaptive management approaches, and ecological and landscape models for use in natural resource decision support. For over 20 years he has worked for State and Federal governments developing and implementing wetland mitigation plans, wetland restoration projects, and monitoring and research programs for the evaluation of wetland restoration projects and programs.  Greg has used conceptual modeling to guide the selection of monitoring variables under the Coastwide Reference Monitoring System (http://www.lacoast.gov/crms2/Home.aspx), to develop desktop models for the evaluation of restoration alternatives for the Louisiana Coastal Area (LCA) (http://www.lca.gov/appc.aspx), and to inform stakeholders regarding wetland restoration and protection (http://www.clear.lsu.edu/clear/web-content/iPages_web/05CEM.html).
