Rocky shores, sandy beaches, salt marshes, estuaries, and underwater habitats like kelp forests, seagrass beds, and reefs.
Why are estuaries important for marine life around the UK?
Estuaries mix freshwater and seawater and are highly productive, serving as nurseries and feeding grounds for many fish, birds, and other species.
How do salt marshes benefit coastal ecosystems and people?
They buffer waves, reduce flooding, filter pollutants, store carbon, and provide habitat for birds and invertebrates.
Which species rely on these habitats?
Seabirds, seals, fish, and marine plants depend on these ecosystems for food, shelter, and breeding sites.
What threats face UK marine and coastal ecosystems?
Pollution, overfishing, coastal development, warming waters, and plastic waste threaten habitats and wildlife.
