Only a strong and diverse coalition of committed people, communities, organizations, businesses and governments will be able to protect the Chesapeake Bay and its watershed. A personal connection between residents of the Bay watershed and their local stream or river is the most vital relationship in our work. People will care for and protect that which they know and love. The Alliance works to create this connection by providing educational experiences and access to resources enabling a diverse coalition of committed people, communities, organizations, businesses and governments to protect the Chesapeake Bay and its rivers. Long known as the neutral broker on Bay information we take seriously our role to engage and educate the citizens and communities that call the Chesapeake Bay Watershed their home.
Our projects bring people together to get dirty and to take on shared conservation challenges while exposing them to the natural world that exists, often just outside their door. These community projects, web resources, and cultural events engender a love of the region and empower adults and youth to take action towards protecting and restoring the Bay and its rivers.
