🏆🏆🏆🏆 Urban Salt Marsh — 600-acre salt marsh in Saugus/Revere — the largest remaining salt marsh in Boston Harbor
Rumney Marsh Reservation protects 600 acres of salt marsh in Saugus and Revere — the largest remaining salt marsh in Boston Harbor. Once slated for industrial development, the marsh was saved by community activism in the 1970s. Today it supports osprey, marsh hawks, and the declining saltmarsh sparrow. The marsh is a critical flood buffer for surrounding communities — absorbing storm surge that would otherwise damage homes and businesses.

Frequently Asked Questions
Why are salt marshes important?
Salt marshes are among the most productive ecosystems on Earth. They filter water, buffer storm surges, sequester carbon, and provide nursery habitat for fish and shellfish. Boston area salt marshes have been reduced by 90% since colonial times — making remaining marshes like Rumney critically important for both ecology and coastal resilience.
