[3] Salt marshes filter pollution from the water and provide food and shelter for numerous species of birds, fish, mammals, and shellfish.
The marsh is a stopover on the Atlantic Flyway, so a myriad of waterfowl can be spotted on the way to Canada in the spring and south to their wintering areas in the fall.
Since early 2000, with the creation of the Friends of Scarborough Marsh, hundreds of acres of open water habitat have been restored by plugging existing ditches and re-creating pools.
The new permanent pools on the high marsh again became home for cordgrass, aquatic invertebrates, mosquito-eating saltmarsh fish and waterbirds including black ducks and glossy ibis.
