Coastal habitats like oyster reefs, seagrass beds, and salt marshes serve as critical nurseries for economically and ecologically valuable fish and invertebrate species, providing access to food and shelter from predators. Scientists and managers have generally assumed that if these habitats were to be degraded or lost the abundance of important marine species would decline. However, researchers have long struggled to provide quantitative estimates of these habitat-species relationships, making it difficult to integrate habitat considerations into management decisions.

The Lenfest Ocean Program is supporting Bryan DeAngelis of The Nature Conservancy, Dr. Philine zu Ermgassen of the University of Edinburgh, and Dr. Jonathan Grabowski of Northeastern University to develop estimates of fish and invertebrate production (weight per area per year) associated with oyster reefs, seagrass beds, and salt marshes in the U.S. Northeast. The research team will also explore the biological and environmental factors associated with each habitat in the Gulf of Mexico and along the Atlantic coast that have the greatest influence on production. This information could improve managers’ ability to target restoration, conservation, and fisheries management measures to rebuild and maintain healthy stocks while maximizing economic benefits.
