# Rebuilding lost marshes

Tidal wetlands clean water draining from the land before it enters the Bay. They absorb pollutants, remove silt, and help reduce shoreline erosion. Marsh grasses are critical habitat for Chesapeake Bay wildlife.

Today, an exciting initiative is underway to re-create lost tidal marshes. Aquarium staff and volunteers are working to restore the Bay's natural filters.

If you live on the shore, leave a natural buffer zone in place or restore original habitat by planting native grasses, trees, and shrubs.

Dredged mud and sand are deposited along shorelines to create a base for rebuilding lost marshes. Nursery-grown, transplanted native grasses take root and hold the mud in place, restoring original marshland.
