Acres of protected land in the Chesapeake Bay watershed hits 9.1 million

November 1, 2023

Chesapeake Bay Program is on course to achieve its Protected Land Outcome

Annapolis, MD— As of 2022, data collected by the Chesapeake Bay Program show that 9.1 million acres of land in the Chesapeake Bay watershed—roughly 22% of the total land in the region—are permanently protected from development.

The Chesapeake Bay Program works to extend the acres of protected lands through its Protected Lands Workgroup, which is led primarily by the National Park Service and includes representatives from state and federal agencies, nonprofits and local governments. In 2010, the partnership set a goal to protect an additional two million acres of land on top of what had been previously protected across the watershed. In particular, the goal calls for 225,000 acres of wetlands and 695,000 acres of forest.

As of 2022, nearly 1.64 million acres have been added since 2010, achieving 82% of the Protected Land Outcome in the Chesapeake Bay Watershed Agreement. The overall Protected Lands Outcome is expected to be achieved by its 2025 deadline.

Protected lands are areas throughout the Chesapeake Bay watershed with cultural, historical, ecological and agricultural value that have been permanently protected from development. Chesapeake Bay Program partners secure land conservation by holding easements, accepting donations and purchasing properties and development rights. Land conservation is one of the best ways to protect the health of the Bay watershed amid a growing population. When protected from development, forests and wetlands can improve water quality, provide habitat for wildlife, preserve the region’s history and culture and offer outdoor recreation opportunities.

State agencies, which own approximately 45% of the protected acres in the watershed, are the largest entity contributing to land protection. The states often work closely with private organizations, non-governmental organizations (land trusts and others), local governments and other entities to conserve the land. The second largest entity contributing to land conservation in the Bay watershed is the federal government, which holds approximately 22% of protected acres.

The Chesapeake Bay Program is on course to meet its Protected Lands Outcome by 2025, which will require adding roughly 130,000 acres of protected lands each year. To meet this goal, the partnership will focus on increasing funding, incentives and mechanisms for protecting conservation priorities, growing the capacity and effectiveness of land trusts and enhancing public support for and engagement in land conservation, among other strategies.


Of the 9.1 million acres of protected land in the watershed, 76% or 7,438,317 acres are forested and 455,853 acres are wetlands. Of the wetland acres, 176,071 of those are non-forested and 279,782 are forested (i.e., swamps).

Pennsylvania currently has the greatest number of protected lands in the watershed at 3.6 million acres. They are followed by Virginia with 2.9 million acres, Maryland with 1.7 million acres, West Virginia with about 440,000 acres, New York with about 332,000 acres, Delaware with about 126,000 acres and the District of Columbia with 8,700 acres.

Watershed-wide, protected lands have increased about 19% from 2011 through 2022. While some increases in acreage can be attributed to improvements in data collection—for instance, by reporting previously protected but newly digitized, corrected or refined parcels of land—the data indicates a general increase in protected lands in the watershed over time. Due to the changing nature of development pressures, conservation incentives, funding for land acquisition and political and public sentiment, experts anticipate some variation between the number of additional acres that are protected each year.


In order to track progress toward its Protected Lands Outcome, the Chesapeake Bay Program utilizes datasets developed both in and outside of the partnership. Improvements to the Protected Areas Database of the United States (PAD-US), the authoritative source for federally protected lands, resulted in certain federal and tribal land as no longer being counted as “protected.” This version of the database, released in 2022, restructured the categorization of protected land type and changed the calculations of protected lands not only for newly added lands, but also for earlier reporting periods. While this decreased the current total number of acres of protected lands reported, it provides more accurate information and the outlook to reach the outcome target by 2025 remains on course.
