Deniz çayırları, or seagrass meadows, are underwater ecosystems formed by flowering plants that grow in shallow coastal waters. These plants, such as Zostera marina and Posidonia oceanica, provide essential habitats for various marine species, including fish, crustaceans, and mollusks. They play a crucial role in maintaining water quality by filtering pollutants and stabilizing sediments. In addition to their ecological importance, deniz çayırları also contribute to carbon sequestration, helping to mitigate climate change. They serve as vital feeding grounds for marine animals, including sea turtles and manatees, and support local fisheries by providing nursery areas for juvenile fish.
