Description: The USGS Protected Areas Database of the United States (PAD-US) is a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public lands and other conservation areas, including voluntarily provided private protected areas. Most areas are protected public lands owned in fee; however, long-term leases and agreements or administrative designations documented in agency management plans may be included. In addition, easements provided by the National Conservation Easement Database (NCED, https://conservationeasement.us ) and the National System of Marine Protected Areas (MPA, https://marineprotectedareas.noaa.gov ) tracked by NOAA are included. Federal and state data are generally complete, while local government and private protected area coverage depends on data management capacity in the state. See the PAD-US companion site (https://dev.protectedlands.net ) for maps of capacity and data completeness by state. Significant improvements to the local government theme are under way in partnership with the Trust for Public Land (TPL). The PAD-US geodatabase contains over twenty-five attributes and four feature classes to support data management, queries, web mapping services and analyses: Marine Protected Areas (MPA), Fee, Easements and Combined. The MPA and Easement feature classes contain some attributes unique to the sole source databases tracking them (e.g. Easement Holder Name from NCED, Protection Level from NOAA MPA Inventory). The "Combined" feature class integrates all fee, easement and MPA features as the best available national inventory of protected areas in the standard PAD-US framework. If desired, MPAs may be removed where "Designation Type" = 'Marine Protected Area' or easements selected where "Category" = 'Easement'. In addition to geographic boundaries, PAD-US describes the category (e.g. fee, easement, other), owner and managing agency, designation type, unit name, area, public access and state name in a suite of standardized fields. An informative set of references (i.e. Aggregator Source, GIS Source, GIS Source Date) and "local" or source data fields provide a transparent link to authoritative data sources. The areas in PAD-US are also assigned conservation measures that assess management intent to permanently protect biological diversity: the nationally relevant "GAP Status Code" and global "IUCN Category" standard. IUCN Categorized protected areas are sent following PAD-US updates to global partners managing the North American PAD (https://CEC.org ) and World Database for Protected Areas (WDPA, https://protectedplanet.net ). See the PAD-US Data Standard at: https://gapanalysis.usgs.gov/padus/ or contact the PAD-US Coordinator for more information. As a full inventory of protected areas by name, aggregated from authoritative source data, PAD-US includes legitimately overlapping designation types (e.g. Wilderness Area over a Wild and Scenic River and National Forest) and sliver errors. Overlapping designations largely occur in the federal theme of the "fee" or "combined" feature classes and may be removed by a selection where "Category" = Designation (DESG). Major sliver errors have been identified and shared with agency data stewards for correction in source files over time. GAP conducts separate analyses to summarize area statistics for PAD-US attributes such as: Owner Name, Manager Name, GAP Status Code, IUCN Category, State Name. Contact the PAD-US Coordinator for more information before conducting area related analyses. PAD-US version 1.4 includes: 1) Complete federal lands theme update: BLM, FWS, NPS, USFS, BIA, DOD, NOAA, USACE and NRCS. USBR, TVA, DOE, ARS transferred from PAD-US 1.3 as best available nationally aggregated data. The federal lands update was developed in collaboration with the FGDC Federal Lands Working Group (https://www.fgdc.gov/participation/working-groups-subcommittees/cadastral/fed-lands-wg-membership ) including lands administered under fee title (e.g. National Forest, National Park, National Wildlife Refuge), congressional designations (e.g. Wilderness, Wild and Scenic River), Presidential proclamations (e.g. National Monuments), administrative protected areas (e.g. BLM ACECs) and conservation easements. Proclamation boundaries are available but are not integrated into PAD-US to reduce overlaps. Documentation tracking the translation of source data into the PAD-US schema is available; contact the PAD-US website or PAD-US Coordinator for more information. 2) 20 PAD-US State Data Steward Network updates to state, local government and / or private protected areas in: Alabama, Alaska, Arizona, California, Florida, Georgia, Indiana, Kansas, Kentucky, Mississippi, Nebraska, Nevada, North Carolina, Oklahoma, Oregon, South Carolina, Texas, Utah, Washington, Wyoming). Information regarding state stewards at: https://gapanalysis.usgs.gov/padus/stewards/ 3) New local government (i.e. county, city) protected areas in 13 states across the country, aggregated by the Trust for Public Land (TPL, https://tpl.org ) for their Conservation Almanac that tracks the conservation finance movement across the country. 4) TNC Lands, national update of lands owned or managed by The Nature Conservancy (TNC, https://maps.tnc.org ). 5) Miscellaneous edits (e.g. Wisconsin County Forests). 6) Integration of non-sensitive easements from the National Conservation Easement Database (NCED, https://conservationeasement.us ) provided by NCED Partners (Duck's Unlimited and TPL). 7) National Marine Protected Areas (MPA) from the NOAA MPA Inventory identified as "member" or "eligible" by NOAA for the National System of Marine Protected Areas (MPA, https://marineprotectedareas.noaa.gov ). 8) Categorical conservation measures assignment reviews by NPS, FWS, BLM, USFS, NOAA. 9) Significantly revised "Designation Type" standard including several new domains. See the GAP Website to download the PAD-US Data Standard for more details. 10) New "Manger Type" and "Manager Name" fields to complement "Owner Name", "Owner Type" and source data (i.e. Local Owner, Local Manager), populated by an Agency Name standard reviewed by the FGDC Federal Lands Working Group. 11) Additional "Date of Establishment" (DOE) records to track the year an area was designated or otherwise protected, provided by PAD-US State Data Stewards and federal partners. This field is not fully attributed; please contact the PAD-US Coordinator to provide additional dates. 12) Additional "Public Access" reviews by select PAD-US Data Stewards and federal partners. Access generally describes (i.e. Open, Closed, Restricted, Unknown) the public's access to protected areas as defined by data stewards for particular units or categorical assignments by Designation Type. 13) The transfer of locally reviewed GAP Status Codes, IUCN Categories, Public Access and DOE from PAD-US version 1.3.
