Who We are

Roy R. "Robin" Lewis III, MA.,P.W.S.

Roy R. "Robin" Lewis III, has over 35 years of experience in seagrass meadow and mangrove forest mapping, management and restoration in the the USA and fifteen foreign countries. He and Dr. Erftemeijer have worked together in Thailand and are the authors of the milestone paper on impacts of dredging on seagrasses published in 2006 and available on this web site. Mr. Lewis and colleague Curtis Kruer also were associated with the worlds largest successful seagrass mitigation project, the Florida Keys Bridges Seagrass Mitigation Project, which is described in the Florida Department of Transportation report found on this web site and in a 1987 scientific paper also found on this website. A total of 134.2 acres (54.3 ha) of seagrass were successfully restored to offset approximately 100 acres (40 ha) of seagrass impacts associated with the replacement of 37 bridges in the Florida Keys, Monroe County, Florida, USA.

Dr. Paul L.A. Erftemeijer is Senior Advisor in Marine Ecology at Deltares (formerly Delft Hydraulics) in The Netherlands. Dr. Erftemeijer has over 20 years of consulting experience with both coral, mangrove and seagrass ecology, mapping, management and restoration around the world. He has worked as project leader for more than 40 advisory projects in 18 different countries, including long-term assignments in Indonesia, Kenya, Thailand and Tanzania, as well as a range of projects in the Arabian Gulf and Mediterranean Sea. Dr. Erftemeijer is a steering committee member of the World Seagrass Association and an invited expert member of the PIANC technical working group on ‘dredging and port construction around coral reefs’. His experience combines a strong scientific background in marine ecology with substantial practical experience in local capacity building and community participation in coastal/marine ecosystem management and restoration in developing countries and many years of professional consultancy experience in marine ecosystem management, mapping and restoration

Curtis Kruer

Mr. Kruer began his professional career in the Indian River Lagoon in the mid-1970s and later spent 11 years working for state and federal wetland regulatory agencies in the Florida Keys beginning in 1977. Restoration and protection of the unique wetland and shallow water habitats of south Florida have been a primary focus of his conservation work as an independent contractor since 1988. He managed the successful Florida Keys Environmental Restoration Trust Fund during the 1990s and led projects to map and eradicate invasive exotic vegetation there. In addition, under contract to state and federal agencies and other entities, Mr. Kruer mapped and described wetland habitats for a Keyswide EPA Advanced Identification of Wetlands project, mapped and described terrestrial habitats of the Keys, mapped coral reef ecosystem habitats throughout the Keys, Puerto Rico, the U.S. Virgin Islands and Biscayne National Park, mapped prop scars for the state boating impact assessment, and mapped and described terrestrial habitats of the Keys. He has assisted in the preparation of litigation and court cases on the state and federal level on numerous occasions and has provided expert testimony in state and federal court in a number of disciplines related to the protection and management of Florida's coastal wetlands and shallow water habitats. In recent years, Mr. Kruer and Coastal Resources Group have assisted with seagrass restoration projects in Tampa Bay and assisted Everglades National Park in defining the extent and significance of the boating impact issue in Florida Bay.
