      <abstract>The United States Geological Survey (USGS) - Science Analytics and Synthesis (SAS) - Gap Analysis Project (GAP) manages the Protected Areas Database of the United States (PAD-US), an Arc10x geodatabase, that includes a full inventory of areas dedicated to the preservation of biological diversity and to other natural, recreation, historic, and cultural uses, managed for these purposes through legal or other effective means (www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/protected-areas). The PAD-US is developed in partnership with many organizations, including coordination groups at the [U.S.] Federal level, lead organizations for each State, and a number of national and other non-governmental organizations whose work is closely related to the PAD-US. Learn more about the USGS PAD-US partners program here: www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/pad-us-data-stewards. The United Nations Environmental Program - World Conservation Monitoring Centre (UNEP-WCMC) tracks global progress toward biodiversity protection targets enacted by the Convention on Biological Diversity (CBD) through the World Database on Protected Areas (WDPA) and World Database on Other Effective Area-based Conservation Measures (WD-OECM) available at: www.protectedplanet.net. See the Aichi Target 11 dashboard (www.protectedplanet.net/en/thematic-areas/global-partnership-on-aichi-target-11) for official protection statistics recognized globally and developed for the CBD, or here for more information and statistics on the United States of America's protected areas: www.protectedplanet.net/country/USA. It is important to note statistics published by the National Oceanic and Atmospheric Administration (NOAA) Marine Protected Areas (MPA) Center (www.marineprotectedareas.noaa.gov/dataanalysis/mpainventory/) and the USGS-GAP (www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/pad-us-statistics-and-reports) differ from statistics published by the UNEP-WCMC as methods to remove overlapping designations differ slightly and U.S. Territories are reported separately by the UNEP-WCMC (e.g. The largest MPA, "Pacific Remote Islands Marine Monument" is attributed to the United States Minor Outlying Islands statistics). At the time of PAD-US 2.1 publication (USGS-GAP, 2020), NOAA reported 26% of U.S. marine waters (including the Great Lakes) as protected in an MPA that meets the International Union for Conservation of Nature (IUCN) definition of biodiversity protection (www.iucn.org/theme/protected-areas/about). USGS-GAP plans to publish PAD-US 2.1 Statistics and Reports in the spring of 2021.

The relationship between the USGS, the NOAA, and the UNEP-WCMC is as follows:

-	USGS manages and publishes the full inventory of U.S. marine and terrestrial protected areas data in the PAD-US representing many values, developed in collaboration with a partnership network in the U.S. and;

-	USGS is the primary source of U.S. marine and terrestrial protected areas data for the WDPA, developed from a subset of the PAD-US in collaboration with the NOAA, other agencies and non-governmental organizations in the U.S., and the UNEP-WCMC and;

-	UNEP-WCMC is the authoritative source of global protected area statistics from the WDPA and WD-OECM and;

-	NOAA is the authoritative source of MPA data in the PAD-US and MPA statistics in the U.S. and; 

-	USGS is the authoritative source of PAD-US statistics (including areas primarily managed for biodiversity, multiple uses including natural resource extraction, and public access).

The PAD-US 2.1 Combined Marine, Fee, Designation, Easement feature class (GAP Status Code 1 and 2 only) is the source of protected areas data in this WDPA update. Tribal areas and military lands represented in the PAD-US Proclamation feature class as GAP Status Code 4 (no known mandate for biodiversity protection) are not included as spatial data to represent internal protected areas are not available at this time. The USGS submitted more than 42,900 protected areas from PAD-US 2.1, including all 50 U.S. States and 6 U.S. Territories, to the UNEP-WCMC for inclusion in the May 2021 WDPA, available at www.protectedplanet.net.

The NOAA is the sole source of MPAs in PAD-US and the National Conservation Easement Database (NCED, www.conservationeasement.us/) is the source of conservation easements. The USGS aggregates authoritative federal lands data directly from managing agencies for PAD-US (www.communities.geoplatform.gov/ngda-govunits/federal-lands-workgroup/), while a network of State data-stewards provide state, local government lands, and some land trust preserves. National nongovernmental organizations contribute spatial data directly (www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/pad-us-data-stewards). The USGS translates the biodiversity focused subset of PAD-US into the WDPA schema (UNEP-WCMC, 2019) for efficient aggregation by the UNEP-WCMC. The USGS maintains WDPA Site Identifiers (WDPAID, WDPA_PID), a persistent identifier for each protected area, provided by UNEP-WCMC. Agency partners are encouraged to track WDPA Site Identifier values in source datasets to improve the efficiency and accuracy of PAD-US and WDPA updates.

The IUCN protected areas in the U.S. are managed by thousands of agencies and organizations across the country and include over 42,900 designated sites such as National Parks, National Wildlife Refuges, National Monuments, Wilderness Areas, some State Parks, State Wildlife Management Areas, Local Nature Preserves, City Natural Areas, The Nature Conservancy and other Land Trust Preserves, and Conservation Easements. The boundaries of these protected places (some overlap) are represented as polygons in the PAD-US, along with informative descriptions such as Unit Name, Manager Name, and Designation Type. As the WDPA is a global dataset, their data standards (UNEP-WCMC 2019) require simplification to reduce the number of records included, focusing on the protected area site name and management authority as described in the Supplemental Information section in this metadata record.

Given the numerous organizations involved, sites may be added or removed from the WDPA between PAD-US updates. These differences may reflect actual change in protected area status; however, they also reflect the dynamic nature of spatial data or Geographic Information Systems (GIS). Many agencies and non-governmental organizations are working to improve the accuracy of protected area boundaries, the consistency of attributes, and inventory completeness between PAD-US updates. In addition, USGS continually seeks partners to review and refine the assignment of conservation measures in the PAD-US.</abstract>
      <purpose>The U.S. Geological Survey (USGS) - Science Analytics and Synthesis (SAS) - Gap Analysis Project (GAP) provides U.S. protected areas data to The United Nations Environmental Program - World Conservation Monitoring Centre (UNEP-WCMC) for the World Database on Protected Areas (WDPA) to track global progress toward biodiversity protection targets (Aichi Target 11) enacted by the Convention on Biological Diversity available at: protectedplanet.net. The USGS manages the Protected Areas Database of the United States (PAD-US), an Arc10x geodatabase, that includes areas dedicated to the preservation of biological diversity and to other natural, recreation, historic, and cultural uses, managed for these purposes through legal or other effective means. The full PAD-US inventory was refined to include areas managed primarily for biodiversity (GAP Status Code 1 and 2 only) and translated into the World Database on Protected Areas (WDPA) format for this data release.</purpose>
      <supplinf>In 2007, the USGS-GAP began collaborating with the UNEP-WCMC and the IUCN protected areas experts to submit data for the WDPA following PAD-US updates. See below for more WDPA submission history information. As a requirement to fulfill the USGS's mission to assess management intent for the long-term protection of biological diversity, PAD-US includes a nationally relevant conservation measure, the GAP Status Code, and the globally recognized IUCN Category measure (www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/pad-us-data-manual). These conservation measures are assigned to each designated management area and many overlap (e.g. Wilderness Area, National Forest). The UNEP-WCMC and the IUCN suggest GAP Status Code 1 and 2 protected areas from PAD-US for inclusion in the WDPA as these areas, primarily managed for the long-term protection of biodiversity, meet the definition of protection defined by IUCN (UNEP-WCMC, 2019; UNEP-WCMC, 2016; Coad et al., 2010). The NOAA manages the MPA Inventory and assigns IUCN Categories to MPAs before sharing data with the USGS for inclusion in the PAD-US. NOAA is the authoritative source of MPAs data and summary statistics for the U.S. available at: www.marineprotectedareas.noaa.gov/dataanalysis/mpainventory/. The USGS, the NOAA, and other agencies and nonprofits collaborate to review and refine conservation measure assignments to ensure terrestrial and marine protected areas in PAD-US, sent to the UNEP-WCMC for inclusion in the WDPA, reflect the best available spatial representation of the U.S. protection network primarily managed for biodiversity. Research to support OECM (www.protectedplanet.net/en/thematic-areas/oecms) submissions from the PAD-US (or other sources) to the UNEP-WCMC for the WD-OECM is pending.

WDPA Submission History:

- First posted - 2009 (Submission 1.0 - available from the PAD-US Team: pad-us@usgs.gov) - Original release of the Protected Areas Database of the United States (PAD-US) by the USGS GAP on behalf of the PAD-US Partnership to the UNEP-WCMC. This was the first demonstration of the PAD-US Partnership that seeks to improve efficiency and leverage resources in protected areas data aggregation and maintenance. The geodatabase standardized regional USGS GAP stewardship data (southwest, southeast, and middle U.S.) with PAD-US Partner data in the northwest (Conservation Biology Institute) and northeast (The Nature Conservancy). USGS GAP worked with UNEP-WCMC to assign International Union for Conservation of Nature (IUCN) Categories to protected areas in PAD-US (GAP Status Code 1 and 2 only) that meet the IUCN definition of protection as "a clearly defined geographical space, recognized, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values." Over 22,000 US protected areas were submitted to UNEP-WCMC for inclusion in WDPA, available at protectedplanet.net.

- Revised - 2010 (Submission 1.1 - available from the PAD-US Team: pad-us@usgs.gov) - The PAD-US Technical Specialist met with the WDPA Data Manager in Cambridge, England to refine data translation protocols and deliver a subset (GAP Status Code 1 and 2 only) of PAD-US 1.1 in the WDPA format. According to the WDPA Data Manager at the time, the U.S. has the largest and most complex dataset in the world. This meeting significantly increased awareness of PAD-US and WDPA data management requirements.

- No WDPA Revision - 2011 (Submission 1.2) - Given the significant resources required for USGS GAP and UNEP-WCMC to update the U.S. protected areas network in the WDPA, both parties agreed to assess the need for future deliveries following each PAD-US update. The decision was made to skip the WDPA contribution from PAD-US 1.2. USGS is challenged by the requirement to maintain WDPA Site Code (WDPAID), a persistent and unique identifier associated with each protected area, as PAD-US data sources do not include WDPAID and many do not include other persistent identifiers to develop a reliable crosswalk to increase data management efficiency and accuracy. 

- Revised - 2013 (Submission 1.3 - available from the PAD-US Team: pad-us@usgs.gov) - The PAD-US Technical Specialist met with the WDPA Data Manager in Alabama to refine data translation protocols and deliver a subset of PAD-US 1.3 (GAP Status Code 1 and 2 only) in the WDPA Schema. This meeting continued to improve our understanding of UNEP-WCMC's requirements for the WDPA, available data in PAD-US, and shared data management capacity.

- Revised - April 2016 (Submission 1.4 - https://www.sciencebase.gov/catalog/item/571a46dde4b071321fe22ce5) - Over 34,000 protected areas were submitted to UNEP-WCMC for inclusion in the WDPA, available at protectedplanet.net.

- Revised - April 2020 (Submission 2.0 - https://www.sciencebase.gov/catalog/item/5b043d1ae4b0da30c1c368c0) - Over 38,000 protected areas were submitted to UNEP-WCMC for inclusion in the WDPA, available at protectedplanet.net.

- Revised - March 2021 (Submission 2.1 - https://www.sciencebase.gov/catalog/item/602ffe50d34eb1203115c7ab) - Over 43,000 protected areas were submitted to UNEP-WCMC for inclusion in the May 2021 WDPA, available at protectedplanet.net.

- Revised - April 2021 (Submission 2.1, version 1.1 - https://www.sciencebase.gov/catalog/item/602ffe50d34eb1203115c7ab) - Over 42,900 protected areas were submitted to UNEP-WCMC for inclusion in the May 2021 WDPA, available at protectedplanet.net. As part of this revision, select countries (Federated States of Micronesia, Marshall Islands, and Palau) were removed from the data submission. The UNEP-WCMC obtains data directly from those governments for the WDPA and therefore removes them from the WDPA PAD-US data submission from USGS. This reduced the total number of submitted features from 43,014 to 42,965. Additionally, values in the ISO3 field for U.S. Territories were changed from 'USA' to their specific Territory code (e.g., ASM, GUM, MNP, PRI, UMI, or VIR). PAD-US assigns 'USA' as the ISO3 code value for all U.S. Territories so that they are included when statistics are calculated for the entire nation. However, the UNEP-WCMC does not include U.S. Territories in USA statistics; as such, Territories are separated out as their own entities.

Note that Waterfowl Production Area (WPA) Easements in PAD-US 2.1 overestimate biodiversity protection (see PAD-US 2.1 Easement feature class where Agg_Src = 'FWS_PADUS2_1Easement_FWSInterest_Simplified' AND Loc_Ds = 'WPA') and are not included in the WDPA 2.1 Submission. The spatial data represents the overall tract boundary containing the wetland easement (about 12.5 million acres primarily in North Dakota and South Dakota) rather than the wetland area protected via easement (an estimated 13% of total parcel area based on documented acres provided by the U.S. Fish and Wildlife Service (FWS)). In consultation with the FWS, the USGS omitted WPA Easements from the WDPA 2.1 submission and will revise their classification in PAD-US 3.0 from GAP Status Code 2 to GAP Status Code 4 to reflect spatial data gaps. They will not be included in the WDPA 3.0 Submission. Please contact the USFWS Cadastral Data Working Group at cdwg@fws.gov with any questions regarding WPA Easements.

      <attraccr>As a compilation of many data sets, attribute completeness and accuracy may vary.

    <logic>The maintenance of WDPA Site Identifier (WDPAID), a persistent identifier for each protected area by name and designation, between updates is challenging as most source data files aggregated for PAD-US do not include persistent identifiers. In addition, names and designations may vary slightly as agency Geographic Information Systems (GIS) are continually developing.</logic>
    <complete>Data set is considered complete for the information presented, as described in the abstract and supplemental information section. Estimated completeness of the PAD-US 2.1 inventory, by Federal agency or State aggregator, is available at www.protectedlands.net/data-stewards/. Qualitative completeness estimates balance acres inventoried and the quality of data/attributes in each inventory, including fee owned parcels, easement interests and major designations. For example, Federal agencies estimate the percent completeness of lands data submitted for PAD-US 2.1 as: NPS (95%), USFS (99%), FWS (89%), BLM (85%), NRCS (85%), and NOAA (95%). The PAD-US 2.1 geodatabase is considered functionally complete; however, USGS continually seeks to improve inventory completeness and spatial data quality in collaboration with agency data-stewards as described in "Completing America's Inventory of Public Parks and Protected Areas: An Action Plan for 2016 - 2020" (2016) available at www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/pad-us-vision .</complete>

        <procdesc>To prepare for WDPA translation, the USGS begins with a selection of records in the PAD-US 2.1 Combined Marine, Fee, Designation, Easement feature class identified as GAP Status Code 1 or 2 areas. These sites are matched, both spatially and by attributes, to the existing WDPA dataset and WDPA Site Identifiers (WDPAID, WDPA_PID), persistent identifiers provided by the UNEP-WCMC and assigned by the USGS, are transferred to PAD-US data or new WDPA Site Identifiers provided by UNEP-WCMC are assigned by USGS to new protected areas. As the WDPA is a global dataset, their data standards (UNEP-WCMC 2019) require simplification to reduce the number of records included, focusing on the protected area site name (NAME) and management authority (MANG_AUTH). All PAD-US 2.1 to WDPA 2.1 translation scripts are available as "Attached Files" at: www.sciencebase.gov/catalog/item/602ffe50d34eb1203115c7ab along with Readme.txt for more information.

The WDPA schema (UNEP-WCMC, 2019) allows for multiple management authorities to be included in the MANG_AUTH field as well as multiple states in the WDPA location field (SUB_LOC), unlike the separation enforced by PAD-US domains. PAD-US data are mapped into these fields with PAD-US Manager Name (Mang_Name) and PAD-US State Name (State_Nm) concatenated by semicolon into the WDPA schema as needed. The WDPA also tracks the following information loaded directly from PAD-US or categorically assigned:

•WDPA Status Year (STATUS-YR) transferred from PAD-US Date of Establishment (Date_Est)

•WDPA Designation (DESG) and Designation in English (DESIG_ENG) transferred from PAD-US Local Designation Type (Loc_Ds) or applied from PAD-US Unit Name

•WDPA Name (NAME) and Original Name (ORIG_NAME) transferred from PAD-US Unit Name (Unit_Nm, with Designations contained in the name removed following WDPA standard)

•WDPA IUCN Category (IUCN) transferred from PAD-US IUCN Category (IUCN_Cat), except where PAD-US IUCN Category value is “Unassigned”, WDPA IUCN Category is “Not Reported”

•GIS derived area (GIS_Area) calculated in square km

•No take (NO_TAKE) information associated with fisheries harvest in Marine Protected Areas (MPA) transferred from PAD-US Marine feature class, Protection Level (Prot_Lvl) field (provided by NOAA MPA Inventory)

•WDPA Governance Type (GOV_TYPE) from PAD-US Manager Type (Mang_Type, converted to WDPA schema)

•WDPA Owner Type (OWN_TYPE) from PAD-US Owner Type (Own_Type, converted to WDPA Schema)

•WDPA Managing Authority (MANG_AUTH) from PAD-US Manager Name (Mang_Name, converted to WDPA Schema)

•Categorically assign WDPA STATUS as "Designated"

•Categorically assign WDPA MARINE = 1 for MPAs from PAD-US (where DESIG or DESIG_ENG = ‘Marine Protected Area’)

•Categorically assign WDPA PA_DEF = 1 as all areas submitted from PAD-US meet the IUCN definition of Protection (i.e. assigned GAP Status Code 1 or 2 in PAD-US).

•Categorically assign WDPA DESIG_TYPE = National as all sites included from PAD-US are national Designations, this Field in the WDPA tracks things like International Ramsar sites

•Categorically assign WDPA Parent_ISO3 = USA for All U.S. Sites and U.S. Territories

• Categorically assign ISO 3 letter codes = USA for All U.S. Sites; = ISO 3 Letter codes for U.S. Territories and USA Free Association Territories (i.e. PRI for Puerto Rico) 

• Categorically assign "Not Applicable" to Supplementary Information (SUPP_INFO) and Conservation Objectives (CONS_OBJ) fields as they are fields applicable in the WD-OECM database only. Research to support OECM (www.protectedplanet.net/en/thematic-areas/oecms) submissions from the PAD-US (or other sources) to the UNEP-WCMC for the WD-OECM is pending.</procdesc>
