The Chesapeake Bay - the largest estuary in the United States - is an incredibly complex ecosystem that includes important habitats and food webs. The Bay and its rivers, wetlands and forests provide homes, food and protection for diverse groups of animals and plants. Fish of all types and sizes either live in the Bay and its tributaries year-round or visit its waters as they migrate along the East Coast.
Ospreys are a top predator in the Chesapeake Bay, and they help scientists study the effects of toxics on our ecosystem.
A watershed is an area of land that drains to a particular river, lake, bay or other body of water. Watersheds are sometimes called “basins” or "drainage basins."
We all live in a watershed. Some watersheds, like that of your local stream or creek, are small. Others, like the Chesapeake Bay watershed, are very large. Learn more about the Chesapeake Bay watershed.
An ecosystem is a complex set of relationships among living and non-living things. Air, water, soil, sunlight, plants and animals – including humans – make up an ecosystem. Ecosystems can be as tiny as a patch of dirt in your backyard, or as large as the entire Chesapeake Bay watershed.
The Chesapeake Bay, the largest estuary in the United States, is an extremely productive and complex ecosystem. The Bay ecosystem consists of the Bay itself, its local rivers and streams, and all the plants and animals it supports. Learn more about the Chesapeake Bay ecosystem.
