What happens on the land directly affects the health of Buzzards Bay. Healthy streams, forests, and wetlands protect clean water. But poorly planned development can lead to more nitrogen pollution in our harbors, coves, and rivers.

This land is called the Buzzards Bay watershed: the 432-square-mile area that drains to the Bay. All of the ponds, streams, and rivers that flow through the watershed eventually lead to the Bay.

The Coalition works throughout the Buzzards Bay watershed to conserve important natural areas and restore damaged streams and wetlands. We’re also spearheading new research on cranberry bogs to solve this piece of the Bay’s pollution puzzle.

Conserving land helps protect clean water in Buzzards Bay. Across our region, the Coalition has forever protected more than 7,500 acres of land in some of the Bay’s most special places. Without saving our most important forests, streams, and wetlands, the Bay – its clean waters, scenic beauty, coastal habitats, and our quality of life – cannot survive.
