One for the Bay
Help support cleaner water, healthier habitat & more abundant life in the Chesapeake Bay.
DonateThe Nature Conservancy is focused on conservation at the scale of entire ecosystems. As North America’s largest estuary, the Chesapeake Bay’s watershed—the area of land that feeds all the water draining into it—covers approximately 64,000 square miles and includes thousands of streams and rivers across six states and the District of Columbia.
Much of the Chesapeake Bay’s watershed lies within the Appalachians—another priority landscape for TNC. Due to their importance in tackling climate change and protecting biodiversity, we are committed to conserving these two globally important landscapes in this critical decade. And in order to succeed, we need your partnership and support.
The stories below highlight the variety of ways that TNC is working across Delaware, Maryland/DC, New York, Pennsylvania, Virginia and West Virginia to protect and restore the Chesapeake Bay.
