Planted with native species, floating wetlands help clean water, and provide habitat for marine life.
In 2021, the Maryland Park Service, in addition to maintaining the State's Parks, restored approximately 40 acres of habitat with tree plantings and pollinator habitat creation and, in an effort to improve water quality, administered stormwater projects.

Some county and municipal governments also oversee local agencies concerned with the environment. Montgomery County, for example, has a Department of Environmental Protection, while the Bureau of Environmental Services in Howard County also oversees some planning functions. In Frederick County, Sustainability and Environmental Resources focuses on sustainability and watershed management, and offers practical ways to protect the environment and conserve energy.

Annual report cards on the health of Maryland's bays are produced by several organizations, including the Maryland Coastal Bays Program, along with the Integration and Application Network of the University of Maryland Center for Environmental Science, and the Department of Natural Resources. The Chesapeake Bay and Watershed received an overall health score of 50%, a C, on their 2021 Report Card, an improvement from 45% in 2020. Ratings are based on seven health indicators for the Chesapeake Bay and five indicators for the Watershed. While the Chesapeake Bay is in moderate health, its Watershed scored C+, based on ecological, economic and societal metrics. Maryland's coastal bays received a "C+" grade on the Combined 2019 & 2020 Coastal Bays Report Card.
The Chesapeake Bay Foundation also produces a State of the Bay report in which 13 indicators are assessed. The 2022 State of the Bay report scored the Bay at 32, or D+. Three indicators showed improvement, while three others worsened. Of these, oysters gained ground while the blue crab population dropped.
