Title: Protected Areas Database of the United States (PAD-US)

Abstract: 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).

Purpose: The PAD-US geodatabase was originally developed to organize and assess the management status (i.e. apply 'GAP Status Code') of elements of biodiversity protection by identifying species and plant communities not adequately represented in existing conservation lands. In cooperation with the United Nations Environment World Conservation Monitoring Centre (WCMC), PAD-US also supports global conservation analyses to inform policy decisions. The dataset is robust and has been expanded in recent years to support the recreation, natural resource management, wildfire, emergency management, transportation, research, and public health communities. New applications are frequently discovered. Multiple attributes and a flexible database structure provide context for data to be used at local (depending on inventory completeness in the local area), regional, State, national, and international scales. See https://gapanalysis.usgs.gov/padus/resources/ for more information.

Spatial Extent of Data: The PAD-US database strives to be a complete inventory of 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. PAD-US is an aggregation of “best available” spatial data provided by agencies and organizations at a point in time. This includes both fee ownership of lands as well as management through leases, easements, or other binding agreements. The data also tracks Congressional designations, Executive designations, and administrative designations identified in management plans (e.g. Bureau of Land Management 'Area of Environmental Concern'). These factors provide for a robust dataset offering a spatial representation of the complex U.S. protected areas network. It is important to have in mind a specific analysis question when approaching how to work with the data. As a full inventory of areas aggregated from authoritative source data, PAD-US includes overlapping designation types and small boundary discrepancies between agency datasets. Overlapping designations largely occur in the Federal estate of the 'Designation' or 'Combined' feature classes (e.g. 'Wilderness Area' over a 'Wild and Scenic River' and 'National Forest'). See the Entity_and_Attribute_Information Section for more information about PAD-US feature classes.

It is important to note the presence of overlaps especially when trying to calculate area statistics; overlapping boundaries count the same area of ground multiple times. While minor boundary discrepancies remain, most major overlaps have been removed from the 'Fee' feature class and this is the best source for overall land area calculations by land manager ('Manager Name') within the PAD-US database (data gaps limit calculations by fee ownership or 'Owner Name'). Statistics summarizing 'Public Access' or Protection Status ('GAP Status Code') by managing agency or organization from an analysis of the PAD-US 1.4 'Combined' feature class are available at https://gapanalysis.usgs.gov/padus/data/statistics/ and will be updated with PAD-US 2.0 in 2018. As the PAD-US database is a direct aggregation of source data, the PAD-US development team does not alter spatial linework. The exception is to “clip” lands data along State boundary lines (using the authoritative State boundary file provided by the U.S. Census Bureau) and remove the small segments of boundaries created by this process associated with State or local lands (not Federal or nonprofit lands). Some boundary discrepancies (or silvers) remain in the dataset. Data overlaps have been identified and are shared, along with the U.S. Census Bureau State jurisdictional boundary file, with agency data-stewards to facilitate edits in source files that will then be incorporated in subsequent PAD-US versions over time.

This PAD-US Version 2.0 dataset includes a variety of updates and changes from the previous version 1.4 dataset (see “Supplemental_Info_Readme.txt” for more information, including story maps and other information that describe PAD-US and various applications). The PAD-US database is built in collaboration with many partners and data-stewards. Information regarding data-stewards is available at http://gapanalysis.usgs.gov/padus/stewards/.

Access Constraints: These data are in the public domain.

Use Constraints: The Digital Object Identifier https://doi.org/10.5066/P955KPLE for PAD-US 2.0 provides the persistent reference that should be used to obtain the data for use.

The U.S. Geological Survey and all contributing data partners shall not be held liable for improper or incorrect use of the data described and (or) contained herein. All information is created with a specific end use or uses in mind. This is especially true for GIS data, which is expensive to produce and must be directed to meet the immediate program needs. These data were created with the expectation that they would be used for other applications; however, inappropriate uses are listed below. This list is in no way exhaustive but should serve as a guide to assess whether a proposed use can or cannot be supported by these data. For many uses, it is unlikely that PAD-US will provide the only data needed, and for uses with a regulatory outcome, authoritative agency data and field surveys should verify the result.

PAD-US is recommended for users seeking basic information about more than one agency or organizations lands. Users should seek authoritative source data directly to answer questions regarding one agency or those requiring more frequent updates. Ultimately, it will be the responsibility of each data user to determine if these data can answer the question being asked.

Inappropriate uses include: Using PAD-US for applications or analyses associated with one agency or a particular unit (agencies are always the best and authoritative source of their lands data and many publish updates more frequently than PAD-US). Using some data to map small areas (less than thousands of hectares), typically requiring mapping resolution at 1:24,000 scale (as boundary quality varies by data source) and using aerial photographs or ground surveys in areas where data are incomplete. Combining these data with other data finer than 1:100,000 scale to produce new hybrid maps or answer queries. Generating specific areal measurements from the data finer than the nearest thousand hectares. Representing boundaries as a legal representation for regulation or acquisition. Establishing definite occurrence or non-occurrence of any feature for an exact geographic area. Determining abundance, health, or condition of any feature. Using the data without acquiring and reviewing the metadata.

Associated Data Sets: Protected Areas Database of the United States (PAD-US)

Section 2: Data Quality

Attribute Accuracy: As a compilation of many data sets, attribute completeness and accuracy may vary. Federal data providers reviewed the translation of their spatial data files into the PAD-US schema and the aggregated database. In addition, the PAD-US team summarized and reviewed the final database and each feature class for overall attribute accuracy and consistency as described in PAD-US 2.0 Summary Review Tables here: https://www.sciencebase.gov/catalog/item/5b043677e4b0da30c1c367e5.

Logical Consistency: Boundary discrepancies (mostly small slivers) between agency datasets and major overlaps associated with fee ownership (mostly between Federal and State lands) have been identified and are shared with agency data-stewards, who will edit source files as resources allow. Users are encouraged to review topology overlap errors associated with the PAD-US Topology Overlap Assessment (https://www.sciencebase.gov/catalog/item/5b043619e4b0da30c1c367e3). The assessment identifies all overlaps (minimum distance between feature coordinates to evaluate overlap relationship = 0.05 meter), large (greater than 5 acres) and small (less than 5 acres) overlaps, between Federal lands and between Federal and State agency lands in the Fee feature class.

Completeness: Data set is considered complete for the information presented, as described in the abstract and supplemental information section. Estimated completeness of the PAD-US 2.0 inventory, by Federal agency or State, is available at http://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 2.0 as: NPS (95%), USFS (99%), FWS (89%), BLM (85%), USACE (80%), DOD (79%), USBR (50%), NRCS (85%), BOEM (95%), NOAA (95%). USGS seeks to increase the completeness, efficiency, and accuracy of PAD-US updates 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" (November, 2016) and "A Map of the Future", published following the PAD-US Design Project (July, 2009) available at https://gapanalysis.usgs.gov/padus/vision/.

Horizontal Positional Accuracy: As a compilation of many data sets, attribute completeness and accuracy may vary. Federal data providers reviewed the translation of their spatial data files into the PAD-US schema and the aggregated database. In addition, the PAD-US team summarized and reviewed the final database and each feature class for overall attribute accuracy and consistency as described in PAD-US 2.0 Summary Review Tables here: https://www.sciencebase.gov/catalog/item/5b043677e4b0da30c1c367e5.

Vertical Positional Accuracy: A formal accuracy assessment of the vertical positional information in the data set is not applicable.

Lineage: PAD-US 2.0 Blank Schema and Manual: The first step in the PAD-US 2.0 development process was to update the Blank PAD-US 2.0 schema (https://www.sciencebase.gov/catalog/item/5b048e4ae4b0d8682b96361d) in response to feedback and the PAD-US Action Plan (https://gapanalysis.usgs.gov/padus/vision/). The blank schema provides a blueprint of the database for the PAD-US Team to load input files for PAD-US development and it is shared with data-stewards seeking to submit source data in the PAD-US format. PAD-US database aggregation involves the compilation of thousands of agency lands data files from nearly 100 data-stewards. Data aggregation and development are an ongoing and evolving process as user and stakeholder feedback improve the process. The Data Manual and schema has changed with each PAD-US version to better reflect user needs. The schema includes all the components to build PAD-US 2.0, including multiple feature classes ('Fee', 'Designation', 'Easement', 'Proclamation', 'Marine', 'Combined'), core attributes, and all standardized domain tables ('State Name', 'IUCN Category', 'GAP Status Code', 'Designation Type', 'Category', 'Agency Type', 'Agency Name', 'Public Access'). The 'Marine' and 'Easement' feature classes also include fields (in addition to PAD-US core attributes) unique to the NOAA Marine Protected Areas Inventory and National Conservation Easement Database (sole sources for data in the Marine and Easement feature classes, respectively). In addition, the Blank PAD-US 2.0 Schema includes the U.S. Census Bureau State file (from the national sub-state geography geodatabase: https://www2.census.gov/geo/pdfs/maps-data/data/tiger/tgrshp2017/2017_TIGER_GDB_Record_Layouts.pdf) that served as the common standard for State jurisdictional boundaries and the 'State Name' field in PAD-US 2.0. The PAD-US development team works closely with a large variety of stakeholders including development partners, data sources, and data users to develop and maintain the "Data Manual for PAD-US" (document available at https://gapanalysis.usgs.gov/padus/data/manual/) with updates regarding PAD-US 2.0 expected late in 2018.

This is a new field added to the PAD-US 2.0 'Combined' feature classes to identify the original feature class ('Fee', 'Easement', 'Designation', etc.) a unit occurred in before combination. This is included to assist users seeking data in the 'Fee' feature class as data gaps exist and 'Category' (which would otherwise define feature class placement) may be 'Other' or 'Unknown'.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Category
-
The general 'Category' for the protection mechanism associated with the protected area. 'Fee' simple is the most common way real estate is owned. A conservation 'easement' creates a legally enforceable land preservation agreement between a landowner and government agency or qualified land protection organization (i.e. land trust). 'Other' types of protection include leases, agreements or deed restrictions. 'Designation' is applied to management boundaries not tied to title documents (e.g. 'National Monument', 'Wild and Scenic River', and some 'State Wildlife Management Area') overlapping fee ownership parcels. 'Marine' includes outer continental shelf lands managed by the Bureau of Ocean Energy Management and Marine Protected Areas identified by the National Oceanic and Atmospheric Administration. 'Proclamation' defines the outer boundaries of areas without internal ownership defined: Military Lands (Department of Defense), Proclamation (National Park Service and Forest Service) and Approved Acquisition Boundaries (U.S. Fish and Wildlife Service).See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Own_Type
-
The general land owner description (e.g. 'Federal', 'Territorial', 'American Indian Lands', 'State', 'Regional Agency Special District', 'Local Government', 'Non-Governmental Organization', 'Private', 'Joint') standardized for the U.S. See PAD-US Data Manual for the “Agency Name to Agency Type Crosswalk” or geodatabase look up table for full domain descriptions. 'Regional Agency Special Districts' include limited purpose governmental units that exist separately from local governments such as county or municipal. 'Designation' is applied to designations overlapping fee lands as ownership is not applicable. Use the 'Manager Type' field for the best general depiction of Federal lands as several ownership related data gaps (i.e. 'Owner Type' = 'Unknown') occur in the Federal theme.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Own_Name
-
Land owner or holding agency (e.g. 'Forest Service', 'State Fish and Wildlife', 'City Land', Non-Governmental Organization') standardized for the U.S. See PAD-US Data Manual or geodatabase 'Agency Name' look up table for full domain descriptions. Please note there are instances where 'Owner Name' = 'Designation' rather than an 'Agency Name' as expected. 'Designation' is applied to designations overlapping fee as ownership (i.e. the 'Owner Name') is not applicable, while it remains a core attribute. A python script assigns 'Owner Name' from 'Local Owner' (PAD-US 2.0 Local Owner to Owner Name Crosswalk at https://www.sciencebase.gov/catalog/item/5b3e9228e4b060350a0efded). 'Owner Name' also contains unknown values where parcel level ownership data are not yet available from authoritative data sources. Use the 'Manager Name' field for the best depiction of Federal lands by agency as several ownership related data gaps (i.e. 'Owner Name' = 'Unknown') occur in the Federal theme.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Loc_Own
-
The name of the land owner as provided by the data source, to complement the standardized 'Owner Name' field (e.g. 'State Fish and Wildlife' is a standard 'Owner Name', while 'Washington Department of Fish and Wildlife' reflect source data in the 'Local Owner' field) as more detail may be provided. A python script assigns 'Owner Name' from 'Local Owner' (PAD-US 2.0 Local Owner to Owner Name Crosswalk at https://www.sciencebase.gov/catalog/item/5b3e9228e4b060350a0efded). Efforts to complete and standardize 'Local Owner' in cooperation with data-stewards are in progress.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Mang_Type
-
General land manager description (e.g. 'Federal', 'Territorial', 'American Indian Lands', 'State', 'Regional Agency Special District', 'Local Government', 'Non-Governmental Organization', 'Private', 'Joint') standardized for the U.S. See PAD-US Data Manual for “Agency Name to Agency Type Crosswalk” or geodatabase look up table for full domain descriptions. Use the 'Manager Type' field for the most complete general depiction of Federal lands as ownership related data gaps (i.e. 'Owner Type' = 'Unknown') occur in the Federal theme.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Mang_Name
-
Land manager or administrative agency (e.g. 'Forest Service', 'State Fish and Wildlife', 'City Land', Non-Governmental Organization') standardized for the U.S. See PAD-US Data Manual or geodatabase look up table for 'Agency Name' for full domain descriptions. A python script assigns 'Manager Name' from 'Local Manager' (PAD-US 2.0 Local Owner to Owner Name Crosswalk: https://www.sciencebase.gov/catalog/item/5b3e9228e4b060350a0efded). Use 'Manager Name' for the best depiction of Federal lands by agency as the 'Owner Name' field includes data gaps (i.e. 'Owner Name' = 'Unknown'), where parcel level ownership data are not yet available from authoritative data sources.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Loc_Manag
-
The name of the land manager as provided by the data source, to complement the standardized 'Manager Name' field (e.g. 'City Land' is a standard 'Manager Name' while 'Agoura Hills, City of' is an example of a 'Local Manager').See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Des_Tp
-
The unit's land management description or 'Designation Type', standardized for the U.S. (e.g. 'Area of Critical Environmental Concern', 'Wilderness Area', 'State Park', 'Local Recreation Area', 'Conservation Easement'). See the PAD-US Data Manual for a crosswalk of 'Designation Type' from source data where 'Local Designation Type' may include related designations in various formats (e.g. NWSR, National Recreation River, National Scenic River, Eligible - Recreational, Eligible - Wild, etc.) or the geodatabase look up table for 'Designation Type' domain descriptions. 'Designation Type' supports PAD-US queries and the categorical assignment of conservation measures (i.e. 'GAP Status Code', 'IUCN Category') and 'Public Access' in the absence of other information.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Loc_Ds
-
The unit's land management description or designation as provided by the data source. 'Local Designation Type' is not standardized and complements the standardized PAD-US 'Designation Type' field as more detail may be available. Null values indicate designation related information was not available in source files and categorical assignments to 'Designation Type' apply. See the PAD-US Data Manual for a crosswalk of 'Designation Type' (e.g. 'State Conservation Area') from source data where 'Local Designation Type' may include various, related designations referenced in source data (e.g. State Natural Area, State Ecological Reserve, State Nature Preserve, State Critical Habitat Area, State Wildlife Management Area, etc.).See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Unit_Nm
-
The name of overall protected area following the PAD-US Standard (i.e. full name including the designation type in Proper Case without acronyms, unit identifiers, special characters, space or return errors), complimenting 'Local Name'. As null values are not permitted in this standardized field, categorical assignments are sometimes made from the 'Manager Name' field and an auto-incremented number for each protected area when data gaps occur in source files. This field is in a state of transition as data-stewards move toward common standards.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Loc_Nm
-
The name of the protected area as provided by the data source; the 'Local Name' field is not standardized. This field may or may not include designations, different formats, spelling errors, unit or area identifiers unique to parcels; however, it links directly to source data files.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
State_Nm
-
Name of State or territory spelled out in Proper Case. U.S. Census Bureau States and Equivalent data serve as the common standard to apply 'State Name' and State jurisdictional boundaries. Protected Areas Database of the United States (PAD-US) Source Data are available at https://www.sciencebase.gov/catalog/item/59cd1685e4b00fa06fefea46 and http://www.protectedlands.net/data-stewards/. See domain descriptions in PAD-US Data Manual or geodatabase look up table for details.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Agg_Src
-
'Aggregator Source' describes the Aggregator (Organization) credited with data aggregation, version of PAD-US when the update occurred, feature class the data reside in (unless mixed), reference to the original source data file, and a reference to describe the State location to manage boundary inconsistencies between agency datasets (from State data-steward submissions only). 'Aggregator Source' is attributed in the format 'organization name_PADUSversion+featureclass_filename.filetype' (e.g. TNC_PADUS1_4_SecuredAreas2008.shp). State aggregations also include a reference to the State in the format 'organization name_PADUSversion_filename.filetype_StateUSPS'. Aggregators may not always be able to define the geodatabase feature class as data may be mixed (e.g. MNDNR_PADUS2_0_MN2015_PADUS_MN_1.gdb_MN, NJOGIS_PADUS2_0Fee_OSPRI_August2017_NJ). Organization acronyms are used and underscore replaces spaces. A data aggregator submits data in the PAD-US format or includes nonprofit aggregators managing regional or national datasets with required fields for PAD-US translation. USGS is identified as aggregator when data translation is required (e.g. USGS_PADUS2_0Fee_BLM_SMA_ADMU_Union). Protected Areas Database of the United States (PAD-US) Source Data are available at https://www.sciencebase.gov/catalog/item/59cd1685e4b00fa06fefea46 and http://www.protectedlands.net/data-stewards/.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
GIS_Src
-
The source of spatial data the aggregator obtained (e.g. WYGF_whmas08.shp) for each record. Files names match original source data provided by managing agencies to increase update efficiency and data transparency. This field is in a state of transition to fully meet standards as the original 'GIS Source' is not always provided in aggregated datasets.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Src_Date
-
This represents the date (yyyy/mm/dd) GIS data was published or obtained (in the case of infrequently updated files) by the data aggregator. If month or day is unknown date is yyyy/00/00. The date an aggregated dataset was delivered to USGS may also be assigned to address data gaps when the original 'GIS Source Date' is not available.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
GIS_Acres
-
Acres calculated for each polygon converted from the Shape_Area field using field calculator "!shape.area@acres!".See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
GAP_Sts
-
The 'GAP Status Code' is a measure of management intent to conserve biodiversity defined as: 'GAP Status Code 1': An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state within which disturbance events (of natural type, frequency, intensity, and legacy) are permitted to proceed without interference or are mimicked through management. 'GAP Status Code 2': An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a primarily natural state, but which may receive uses or management practices that degrade the quality of existing natural communities, including suppression of natural disturbance. 'GAP Status Code 3': An area having permanent protection from conversion of natural land cover for most of the area, but subject to extractive uses of either a broad, low-intensity type (e.g., logging, Off Highway Vehicle recreation) or localized intense type (e.g., mining). It also confers protection to Federally listed endangered and threatened species throughout the area. 'GAP Status Code 4': There are no known public or private institutional mandates or legally recognized easements or deed restrictions held by the managing entity to prevent conversion of natural habitat types to anthropogenic habitat types. The area generally allows conversion to unnatural land cover throughout or management intent is unknown. See the PAD-US Standards Manual for a summary of methods or the geodatabase look up table for short descriptions.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
GAPCdSrc
-
An acronym to describe the organization(s) that applied 'GAP Status Code' to a unit boundary. This field also describes the methods used for assigning GAP Status as follows: 'GAP - Default' is assigned when GAP's categorical assignment of status has been applied, without more detailed review or inquiry. 'GAP' is assigned when standard methods (includes management plan review or land manager interview to assign GAP Status to a protected area) apply. 'GAP - Other Organization' (e.g. 'GAP - NPS') applies when the measure is assigned in partnership with GAP, including review. 'Other Organization' is assigned when another organization applied GAP Status according to their methods then (e.g. The Nature Conservancy).See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/

IUCN_Cat
-
International Union for the Conservation of Nature (IUCN) management categories assigned to protected areas for inclusion in the United Nations Environment World Conservation Monitoring Center (WCMC) World Database for Protected Areas (WDPA) and the Commission for Environmental Cooperation (CEC) North American Terrestrial Protected Areas Database. IUCN defines a protected area 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" (includes GAP Status Code 1 and 2 only). Categorization follows as: 'IUCN Category Ia': Strict Nature Reserves are strictly protected areas set aside to protect biodiversity and possibly geological or geomorphological features, where human visitation, use and impacts are strictly controlled and limited to ensure preservation of the conservation values. Such protected areas can serve as indispensable reference areas for scientific research and monitoring. 'IUCN Category Ib': Wilderness Areas are protected areas are usually large unmodified or slightly modified areas, retaining their natural character and influence, without permanent or significant human habitation, which are protected and managed to preserve their natural condition. 'IUCN Category II': National Park protected areas are large natural or near natural areas set aside to protect large-scale ecological processes, along with the complement of species and ecosystems characteristic of the area, which also provide a foundation for environmentally and culturally compatible spiritual, scientific, educational, recreational and visitor opportunities. 'IUCN Category III': Natural Monument or Feature protected areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine caverns, geological feature such as caves, or even a living feature such as an ancient grove. They are generally quite small protected areas and often have high visitor value. 'IUCN Category IV': Habitat and (or) species management protected areas aim to protect particular species or habitats and management reflects this priority. Many category IV protected areas will need regular, active interventions to address the requirements of particular species or to maintain habitats, but this is not a requirement of this category. 'IUCN Category V': Protected landscape and (or) seascape protected areas occur where the interaction of people and nature over time has produced an area of distinct character with significant ecological, biological, cultural, and scenic value. 'IUCN Category VI': Protected area with sustainable use (community based, non-industrial) of natural resources are generally large, with much of the area in a more-or-less natural condition and whereas a proportion is under sustainable natural resource management and where such exploitation is seen as one of the main aims of the area. 'Other Conservation Areas' are not recognized by IUCN at this time; however, they are included in the CEC's database referenced above. These areas (includes GAP Status Code 3 areas only) are attributed in the 'IUCN Category' Domain along with 'Unassigned' areas (GAP Status Code 4). In addition, a few areas are included as 'Not Reported', these areas meet the definition of IUCN protection (i.e. GAP Status Code 1 or 2) but 'IUCN Category' has not yet been assigned and categorical assignment is not appropriate. See the PAD-US Standards Manual for a summary of methods.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
IUCNCtSrc
-
An acronym to describe the organization(s) that applied 'IUCN Category' to the polygon. This field also describes the methods used for assigning 'IUCN Category' as follows: 'GAP - Default' is assigned when GAP's categorical assignment of status has been applied, without additional review. 'GAP - Other Organization' (e.g. 'GAP - NPS') applies when the measure is assigned in partnership with GAP, including review. 'Other Organization' applies when IUCN Category is assigned by another organization according to their methods (e.g. NOAA) is assigned. See the PAD-US Standards Manual for more information.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/

Access
-
Level of 'Public Access' permitted, described as: 'Open' requires no special requirements for public access to the property (may include regular hours of availability); 'Restricted' requires a special permit from the owner for access, a registration permit on public land (e.g. self-permitting Wild and Scenic River, backcountry Wilderness registration) or has highly variable times when open to use; 'Closed' occurs where no public access is allowed (e.g. land bank property, special ecological study areas, military bases, many easements, etc.). 'Unknown' is assigned where information is not currently available. 'Public Access' was provided by State data-stewards, Federal, nonprofit partners or assigned categorically by 'Designation Type' when no other information was available.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/

Date_Est
-
The Year (yyyy) the protected area was designated, decreed or otherwise established. The date is assigned to each unit by name and designation type, without event status (e.g. Yellowstone National Park: 1872, Frank Church-River of No Return Wilderness Area: 1980). This field is not fully attributed and data gaps are difficult to address.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
Source_PAID
-
The 'Source Protected Area Identifier' (Source PAID) includes the persistent identifier (e.g. numbers, letters, or combinations of each) associated with each protected area, when available in source data. The intention is to maintain a reliable connection to join authoritative source data to previous PAD-US versions (to transfer attributes not available in source data) and support links to other data. This field is not fully attributed and significant work remains to ensure persistent identifiers are provided by data-stewards. Several Federal data-stewards provided 'Source PAID' for PAD-US 2.0 and the FLWG plans to continue work in 2018-19 to ensure this field is operational for the Federal estate in the PAD-US format.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
WDPA_Cd
-
The 'World Database for Protected Areas (WDPA) Site Code' is assigned by the UNEP World Conservation Monitoring Centre (WCMC) to all areas submitted to the WDPA. USGS maintains these codes, assigned to overall protected areas by 'Unit Name' (includes 'Designation Type'), between PAD-US updates. Areas identified as 'GAP Status Code' 1 or 2 meet the definition of protection by the International Union for the Conservation of Nature (IUCN) and are submitted to WCMC for the WDPA. Other areas will not have a 'WDPA Code'. A derivative PAD-US product, with all 'WDPA Codes', is sent to WCMC for the WDPA following each PAD-US update. This field is incomplete at this time, pending additional code assignments by WCMC following PAD-US 2.0 publication and review.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
EHoldTyp
-
'Easement Holder Type' is the general description (e.g., 'Federal', 'Tribal', 'State', 'Private') of the easement holder, following the PAD-US 'Agency Type' domain codes and descriptions. This is a core attribute in the National Conservation Easement Database (NCED) that was transferred to the PAD-US Easement and various Combined feature classes.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
EsmtHldr
-
'Easement Holder' is the name of the organization managing or holding the easement standardized by NCED to Proper Case with all acronyms spelled out (e.g., The Nature Conservancy [TNC]). This is a core attribute in the National Conservation Easement Database (NCED) provided by the easement holder or data provider that was transferred to the PAD-US 'Easement' and various 'Combined' feature classes.See PAD-US Data Manual Document available at https://gapanalysis.usgs.gov/padus/data/manual/
