The First World Map of Tidal Marshes: Mapping Critical Coastal Ecosystems for People and Nature

Summary

The first high resolution global map of tidal marshes marks a major advancement in understanding one of the world's most important coastal ecosystems. Developed through collaboration between researchers and conservation organizations, the map reveals the global distribution of tidal marshes and highlights their ecological and societal value. These ecosystems support diverse plant and bird species, serve as vital nursery habitats for fish, store significant amounts of carbon in deep soils, and help protect coastlines from erosion, flooding, and storm surges. The map provides critical data that can support conservation planning, habitat restoration, carbon accounting, climate adaptation, and policy development. By offering a consistent global view of tidal marshes, the research helps scientists, practitioners, and governments better understand ecosystem losses, identify restoration opportunities, and strengthen efforts to protect these highly productive and valuable coastal environments around the world.
