Coastal Ecosystems
Complex and dynamic natural systems occurring at the interface of land and sea, characterized by diverse habitats that support unique biodiversity and provide critical environmental services.
Coastal Ecosystems
Coastal ecosystems represent vital transition zones where terrestrial and marine environments converge, creating some of Earth's most productive and vulnerable natural systems. These dynamic environments serve as critical buffers against storm surge and coastal erosion while supporting remarkable biodiversity.
