Seegraswiesen are wetlands characterized by the presence of aquatic plants, particularly seegras or seagrass. These areas are typically found in shallow coastal waters and play a crucial role in maintaining marine ecosystems. They provide habitat for various marine species, including fish and invertebrates, and help stabilize the seabed. Additionally, Seegraswiesen contribute to water quality by filtering pollutants and absorbing excess nutrients. They also serve as important carbon sinks, helping to mitigate climate change. Overall, these ecosystems are vital for biodiversity and the health of marine environments.
