The Alliance for the Chesapeake Bay engages individuals, businesses, and environmental organizations to develop solutions to improve, preserve, and protect the Chesapeake Bay and all its resources.  The Alliance focuses on community efforts, such as the Local Government Advisory Committee, the Citizens Advisory Committee, the BayScaping program, the Watershed Forum and Project Stream Clean.

The Chesapeake Bay Commission was created in 1980 to coordinate Bay-related policy across state lines and to develop shared solutions. The Commission is a tri-state legislative assembly representing Maryland, Virginia and Pennsylvania that deals with issues including managing living resources, protecting water quality and conserving land.

The Chesapeake Bay Foundation (CBF) advocates for the Chesapeake Bay by finding solutions to the pollution problems of the Bay and its tributaries. Across the six-state Chesapeake watershed, CBF sets the agenda, serves as a watchdog, and speaks out on behalf of the Chesapeake Bay to business, government, and the public. CBF works on restoration, advocacy, education and litigation. 

The Chesapeake Bay Program is a regional partnership that leads and directs Bay restoration and protection. Bay Program partners include federal and state agencies, local governments, non-profit organizations and academic institutions that help advance Bay science, policy and restoration. CBP also coordinates scientific data, environmental indicators, educational resources, and public information on the Bay’s pollution problems.

The Trust is a nonprofit, grant-making organization dedicated to restoring the Chesapeake Bay and its tributaries in Maryland. Since 1985, they have awarded over $45 million through 8,000 grants. Last year their 110,000 volunteers, teachers and students planted 95,000 native trees and plants, removed 580 tons of trash from streams and rivers, created 7,100 linear feet of living shoreline and restored 70 acres of wetlands, oyster reefs, and streamside buffers. 

The Chesapeake Conservancy is dedicated to ensuring conservation, stewardship and access of the Chesapeake Bay, its lands and rivers. The Conservancy was created out of a merger between the Friends of the John Smith Chesapeake Trail and Friends of Chesapeake Gateways.

The Chesapeake Legal Alliance, Inc. (CLA) is a not-for-profit organization dedicated to using the law to improve the quality of the Chesapeake Bay.  CLA coordinates a network of lawyers who volunteer their time and professional skills to representing environmental organizations, citizens’ groups, and individuals in their efforts to improve the health of the Chesapeake and its watershed. 

The Chesapeake Executive Council launched the first version of ChesapeakeStat in June 2010 to increase government accountability and improve coordination of restoration actions by providing information on partner activities, funding, and progress towards goals. ChesapeakeStat is a systematic process within the Partnership of analyzing information and data to continually assess progress towards goals and adapt strategies and tactics when needed.

It serves as a public website that promotes improved accountability, fosters coordination, and promotes transparency by sharing performance information on goals, indicators, strategies, and funding.

The National Oceanic and Atmospheric Administration's (NOAA) Chesapeake Bay Office is a division of the National Marine Fisheries' Office of Habitat Conservation, which works to protect and restore coastal and marine habitat at the national level. The Office is also a key collaborator with NOAA's North Atlantic Regional Team, which integrates NOAA's program activities to address priorities at both the national and regional scale.  NOAA has been a partner in Chesapeake Bay Program restoration and protection efforts since the signing of a Memorandum of Understanding with the U.S. Environmental Protection Agency in 1984.

The Smithsonian Environmental Research Center (SERC) provides science-based knowledge to meet the environmental challenges of the 21st century. SERC leads research on coastal ecosystems—where land meets the sea—to inform real-world decisions for wise policies, best business practices, and a sustainable planet.  Since its creation in 1965, SERC has been conducting peer-reviewed research to understand the causes and consequences of rapid change in the Chesapeake Bay and around the world.
