About Us Atlantic and Gulf Rapid Reef Assessment


AGRRA was formed in 1998 to assess key attributes of coral reefs in the tropical Western Atlantic and to inform reef policies, legislation, management and conservation.

Our goals at AGRRA are to conduct scientifically sound, comparable regional surveys of the health of coral reefs using a standardized method; summarize the results and provide easy access to our data platform and on-line data entry tool; promote a learning network through trainings, exchanges and education materials, and catalyze conservation impact through creative effective communication to wider audiences.


DSC_0759The Atlantic and Gulf Rapid Reef Assessment (AGRRA) Program is an international collaboration of scientists, managers, conservationists and students.

We maintain an extensive, open-access, regional database of coral-reef condition indicators for the wider Caribbean area.  More than 2,000 of the surveys which have been conducted in 28 countries or territories since 1998 are stored in the AGRRA database. These data provide valuable, temporal baseline or time-series data to scientists and government officials responsible for marine management.



Coral Reef Monitoring

There are several major types of coral reefs in the Caribbean, each with a unique geological history and pattern of growth, including patch reefs, fringing reefs, bank/barrier reefs and atolls. The vitality of a reef depends on complex relationships among corals, fishes and algae. Therefore, to evaluate the condition of a reef from a one-time assessment, it is critical that multiple indicators of the corals-algae-fishes relationships are examined. These different indicators are measured by the AGRRA protocol.



Data Explorer

AGRRA’s Data Explorer houses the largest database on Caribbean coral reef health indicators, with data available from more than 2,000 reef areas in 28 countries throughout the Caribbean. You can explore the data through our database, ready-made spreadsheets and GIS shapefiles. The PORT allows you to generate individually customized reports by country, indicator, year. The Online Data Entry System allows registered users to enter data directly into the database. (Member login required).


marker2Educational and Training Materials

Our in-depth training materials include PowerPoint or PDF files for learning the AGRRA method, making survey equipment and identifying the benthos, coral and fish. Other training tools are available to help improve accuracy and consistency of collected data. A special section is available with teaching aids for our AGRRA Certified Trainers who conduct AGRRA training workshops. (Member login required).

AGRRA has partnered with several groups who use AGRRA data to produce coral reef report cards and other publications. Report cards are an easy to understand communication tool that integrate survey data to provide an overview of the current state of the reefs and to engage stakeholders to help protect marine ecosystems. Reporting this type of information helps track progress in protecting reefs and inform future monitoring and management.

AGRRA has collaborated on Report Cards with: The Healthy Reefs Initiative for four Mesoamerican Countries; The Nature Conservancy, Bahamas National Trust and the Blue Project for the Bahamas and The Nature Conservancy for 6 countries in the Eastern Caribbean. AGRRA data have also been used in many scientific publications and reports. More can be found on our Resources page.
