coastal ecosystems
Where land meets ocean
Coastal ecosystems are the interconnected communities of organisms and their physical environments found where land meets sea—including salt marshes, mangroves, estuaries, tidal flats, coral reefs, and shoreline habitats.
These zones are among the most productive and biologically diverse on Earth, serving as nurseries for fish, buffers against storms, and filters for pollutants.
Coastal ecosystems face increasing pressure from development and rising sea levels.
The term appears frequently in environmental policy and conservation discussions.
