Service Description: This data represents the most up to date version of protected lands within the Chesapeake Bay Watershed. The data aggregates of multiple State, Federal and Non-Governmental Organization sources, due to the nature of the datasets overlapping and duplicate areas may be present. The Chesapeake Bay Program defines protected lands as lands that are permanently protected from development, whether by purchase, donation, a perpetual conservation or open space easement, or fee ownership for their cultural, historical, ecological, or agricultural value. This definition includes non-traditional conservation mechanisms like transfer or purchase of development rights programs. Lands protected through easements and purchase of development rights typically remain in private ownership. Protected lands include county, town, city, state and federal parks; designated open space and recreational land; publicly owned forests and wetlands; privately owned working farms or forests with conservation easements; historically important lands, such as protected battlefields, colonial towns and farms; military-owned parks and recreational areas. Please refer to the methods and guidance document associated with this indicator for details on the datasets used, limitations and changes in the process of aggregating the datasets.

Description: This dataset is an aggregated layer of protected lands in the Chesapeake Bay Watershed and intersecting counties. It is a combination of multiple state, federal and non-governmental organization sources. There has been limited effort to reduce duplicative records and overlapping areas. It is not recommended to make acreage calculations using this dataset. It is current as of March 2019, though most of the data was collected through 2018.The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme (https://communities.geoplatform.gov/ngda-cadastre/). The PAD-US is an ongoing project with several published versions of a spatial database including areas dedicated to the preservation of biological diversity, and other natural (including extraction), recreational, or cultural uses, managed for these purposes through legal or other effective means. The database was originally designed to support biodiversity assessments; however, its scope expanded in recent years to include all public and nonprofit lands and waters. Most are public lands owned in fee; however, long-term easements, leases, agreements, Congressional (e.g. 'Wilderness Area'), Executive (e.g. 'National Monument'), and administrative designations (e.g. 'Area of Critical Environmental Concern') documented in agency management plans are also included. The PAD-US strives to be a complete inventory of public land and other protected areas, compiling “best available” data provided by managing agencies and organizations. The PAD-US geodatabase maps and describes areas with over twenty-five attributes in nine feature classes to support data management, queries, web mapping services, and analyses. This PAD-US Version 2.0 dataset includes a variety of updates and changes from the previous Version 1.4 dataset. The following list summarizes major updates and changes: 1) Expanded database structure with new layers: the geodatabase feature class structure now includes nine feature classes separating fee owned lands, conservation (and other) easements, management designations overlapping fee lands, marine areas, proclamation boundaries and various 'Combined' feature classes (e.g. 'Fee' + 'Easement' + 'Designation' feature classes); 2) Major update of the Federal estate including data from 8 agencies, developed in collaboration with the Federal Geographic Data Committee (FGDC) Federal Lands Working Group (FLWG, https://communities.geoplatform.gov/ngda-govunits/federal-lands-workgroup/); 3) Major updates to 30 States and limited additions to 16 other States; 4) Integration of The Nature Conservancy's (TNC) Secured Lands geodatabase; 5) Integration of Ducks Unlimited's (DU) Conservation and Recreation Lands (CARL) database; 6) Integration of The Trust for Public Land's (TPL) Conservation Almanac database; 7) The Nature Conservancy (TNC) Lands database update: the national source of lands owned in fee or managed by TNC; 8) National Conservation Easement Database (NCED) update: complete update of non-sensitive (suitable for publication in the public domain) easements; 9) Complete National Marine Protected Areas (MPA) update: from the NOAA MPA Inventory, including conservation measure ('GAP Status Code', 'IUCN Category') review by NOAA; 10) First integration of Bureau of Energy Ocean Management (BOEM) managed marine lands: BOEM submitted Outer Continental Shelf Area lands managed for natural resources (minerals, oil and gas), a significant and new addition to PAD-US; 11) Fee boundary overlap assessment: topology overlaps in the PAD-US 2.0 'Fee' feature class have been identified and are available for user and data-steward reference (See Logical_Consistency_Report Section).
