The Wildlife of Our Watershed

Join us as we dive into the amazing wildlife that calls the Chesapeake Bay watershed home.

The Chesapeake Bay watershed spans 64,000 square miles throughout New York, Pennsylvania, Delaware, Maryland, Virginia, West Virginia, and Washinton, D.C. To put that into perspective, that’s more than 14 times the size of the Chesapeake Bay itself. This expansive, diverse land is home to more than 18 million people and over 3,000 plant and animal species. There’s a wide range of landscapes and even more life to explore throughout the watershed, so we’re glad you’re here.

Animals Upstream

“Animals Upstream” is an engaging four-part video series that unveils the often-overlooked wonders within the Chesapeake Bay watershed. When one thinks of the Chesapeake Bay, images of rockfish, oysters, and blue crabs likely come to mind. While these are iconic to the region, the watershed extends across 64,000 square miles and provides a home to more than 3,600 species of plants and animals.
