“Saving our precious coast lines one man grove at a time.”

About Us

Coastal Resource Group is a 501 c 3 non-profit organization that works with public and private partners to conserve Florida’s native coastal wetlands. Founded in 2004 it provides scientific and technical expertise in the ecology, restoration and management of mangroves, salt marshes, and seagrasses. CRG’s biologists have been involved in habitat restoration in the Florida Keys since 1980, carrying out Florida’s largest seagrass restoration project, and managing the original Keys Restoration Trust Fund in the 1990s. Our Florida Keys projects are financed through the Keys Restoration Fund.


Meet the team


Laura L. Flynn


Laura Flynn is a wetland scientist and practitioner specializing in the restoration and conservation of coastal habitats with a primary focus on mangrove, salt marsh and seagrass ecosystems.  Ms. Flynn has 15 years of experience working with Mr. Lewis and CRG in coastal conservation and educational outreach programs to promote awareness and restoration techniques to improve the success of projects by all restoration practitioners throughout Florida.  Ms. Flynn has mapped historical longshore bars for the management of seagrasses by the Tampa Bay National Estuary Program and is currently assisting Charlotte Harbor National Estuary Program with the mapping of mangrove and salt marsh habitats throughout Charlotte Harbor. Ms. Flynn has worked with Mr. Lewis to complete over 20 local restoration projects including the restoration and preservation of islands within Pelican Island, the nation’s first National Wildlife Refuge, and the restoration of approximately 100 acres of mangrove, salt marsh and oyster habitat near the Alafia River, Tampa Bay. Ms. Flynn assists with coordination, mapping and field work to implement the restoration of approximately 200 acres of mangrove forest at Rookery Bay National Estuarine Research Reserve (RBNERR) and works with research partners on new techniques and approaches to identify areas of mangrove stress prior to die off of these habitats. Ms. Flynn facilitates the sale of mitigation credits and the subsequent implementation of large scale mitigation projects for the Keys Restoration Fund Federal In-Lieu Fee Mitigation Program in the Florida Keys.


Curtis Kruer

Vice President

Curtis 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. 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. 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, and mapped prop scars for the state boating impact assessment. He has assisted in the preparation of litigation and court cases on numerous occasions and has provided expert testimony in state and federal court 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.

Fruit Creek Farms

Reviving Black Mangrove Habitats at Rookery Bay National Estuarine Research Reserve

In 1938 construction of SR 92 blocked natural tidal flow and drainage through Fruit Farm Creek flooding acres of black mangroves. Mangroves grow in intertidal zones but drown when submerged for long periods. CRG is working on a multi-phase project to restore circulation by removing blockages, reopening drainage channels, and installing culverts with grants from US Fish & Wildlife Service and public and private partners.

CRG’s hydrological restoration project benefits 225 acres of mangroves between Goodland and Marco Island.

Heavy equipment is used to remove obstacles to tidal flow including fill, vegetation, roots, and debris.

Culverts are installed under roads and channels are reopened for drainage through the mangrove swamp.


Pelican Island National Wildlife Refuge

Saving a National Treasure from Erosion

Pelican Island is an important bird rookery in Indian River Lagoon.  In 1903 it became the first federal land set aside specifically for wildlife. Since then it has eroded dramatically due to wave action. By 2000 it had lost more than half of its original 5.5-acre area. Proactive steps were urgently needed to stop erosion and preserve critical nesting habitat for 16 different species of birds, including these threatened Wood Storks.



Before After CRG Shoreline Stabilization Project

In partnership with US Fish and Wildlife Service, Army Corps of Engineers and others, CRG carried out an innovative plan to install an oyster shell wavebreak and plant smooth cordgrass and mangroves to protect the island shoreline and encourage natural sediment accretion over time.

165 ft. of oyster shell were placed by hand in Phase I.   A helicopter was used to airlift in 930 ft. of oyster shell with minimal disturbance in Phase II. Phase III included 260 more cubic yards of shell and 900 cubic yards of sand. Volunteers helped with planting thousands of wetland plants.
