Data collected between 2015 and 2016 show that, since 2010, approximately 1,004,577 acres of land in the Chesapeake Bay watershed have been permanently protected from development. This marks an achievement of 50 percent of the land conservation goal adopted in the Chesapeake Bay Watershed Agreement and brings the total amount of protected land in the watershed to 8.8 million acres.

Some increases in acreage can be attributed to newly protected parcels of land. Other increases can be attributed to the addition of previously protected but newly digitized, corrected or refined parcels.

Protected Land Ownership (2015-2016)

Watershed-wide, protected lands have increased 13 percent since 2010. 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—other increases can be attributed to newly protected parcels of land. Because state and other protected lands databases do not consistently include the date of protection (i.e., the “date established”) for parcels, it is impossible to determine the extent to which either factor has influenced observed increases in acreage over time. Due to the changing nature of development pressure, 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.

The 8.8 million acres of protected lands in the watershed—which account for 22 percent of the total land in the region—include: 3.3 million acres in Pennsylvania; 2.9 million acres in Virginia; 1.7 million acres in Maryland; close to 410,000 acres in West Virginia; close to 323,000 acres in New York; close to 108,000 acres in Delaware; and more than 11,000 acres in the District of Columbia.

State agencies are the largest entity contributing to land protection: they own approximately 46 percent of the protected acres in the watershed. Watershed-wide, the federal government holds approximately 25 percent of the protected acres. Private organizations, non-governmental organizations, local governments and other entities have also been extremely active in land conservation and will remain critical partners in land protection efforts.

For decades, our partners have permanently protected lands with cultural, historical, ecological and agricultural value by holding easements, accepting donations and purchasing properties and development rights. Because protected lands can support sustainable fisheries and wildlife habitat, protect clean water and healthy watersheds, and preserve our cultural values, putting land under protection is one way to ensure the watershed withstands population growth and sustains the plants, animals and people that live here.

Tracking our progress toward protecting land from development is also critical to understanding our progress toward enhancing climate resiliency. Protected lands prevent the expansion of paved surfaces that can exacerbate nutrient pollution, harmful algal blooms and upstream floods. Along the coast, protected lands guard against floods and sea level rise. For these reasons, protected lands help us prepare for some of the disruptions climate change can cause.

In the future, this indicator may be enhanced to express the value of protected lands to climate resiliency and the quality of their protection against the impacts of climate change. A tract of land could be considered more valuable, for instance, if it provided habitat to a plant or animal threatened by climate change. A means of land protection could be considered more valuable if it prohibited shoreline hardening or allowed tidal wetlands to migrate inland in response to rising seas.

Management Strategy

To achieve this outcome, Chesapeake Bay Program partners have committed to:

  • Identifying shared conservation priorities;
  • Increasing funding, incentives and mechanisms for protecting conservation priorities;
  • Improving the quality, quantity and accessibility of conservation data;
  • Increasing the capacity and effectiveness of land trusts;
  • Building an active network of land conservation organizations in the watershed; and
  • Increasing public support for and engagement in land conservation.

Monitoring and assessing progress toward the outcome will occur through the compilation of land conservation data from watershed jurisdictions, the Protected Areas Database of the United States (PAD-US) and the National Conservation Easement Dataset.

As part of the Chesapeake Bay Program’s partnership-wide implementation of adaptive management, progress toward this outcome was reviewed and discussed by the Management Board in May of 2017.

Work Plan

Chesapeake Bay Program partners have committed to taking a series of specific actions that will support the management approaches listed above.
