  • 2001-Present:   Comprehensive Everglades Restoration Plan (CERP) Teams; member of 5 CERP teams, currently serving on Southern Coastal Systems Sub-Team of RECOVER (REstoration COordination and VERification)
  • 2002:   DOI and USGS Science Plans in Support of Greater Everglades Ecosystem Restoration; one of five USGS scientists that drafted plans for Bureau and Department
  • 2009-2013:   NOAA interagency group, Marine and Estuarine Goal Setting for South Florida; USGS member of group setting goals and writing ecological models for South Florida’s marine environments; lead author on one conceptual ecological model.
