Description: These infrastructure data were originally compiled by Audubon in 2014 and provided to the Bureau of Land Management (BLM) Rapid Ecological Assessment (REA) project for the North Slope region. Those data were edited by the Alaska Center for Conservation Science (ACCS) for the REA and released for public distribution on the BLM/REA website. The North Slope Science Initiative (NSSI) subsequently updated the REA product using high resolution imagery as a verification base and heads up digitizing to produce an initial version of this infrastructure dataset. Annual updates to these data have been performed by ACCS and funded by BLM. This 2023 update is based on interpretation of 2022 Sentinel imagery for the Prudhoe Bay development area and other image products as available for the greater North Slope region. Additional attribute and location geospatial data from Alaska Department of Natural Resources - Geo-Spatial Clearinghouse and Alaska Division of Oil and Gas are included.All locations are approximate. Neither ACCS, BLM, NSSI or other contributors to this dataset shall be held liable for improper or incorrect use of the data described and/or contained herein. In an effort to provide the most comprehensive overview possible, these updates have incorporated many data sources, using a variety compilation methods. As a result, there are a variety of limitations to the thematic and spatial accuracy of these data. The appropriate use of these data is the responsibility of the user.

Description: This data contains the administrative large parcel boundaries for both the state and federal government. It combines the formerly known Legislatively Designated Areas (LDA's), or state parcels, and the Conservation System Units (CSU's), or federal parcels, with data improvements. The CSU's also contained additional federal management units, such as National Forests; hence, the name change. Data improvements are significant compared to previous versions of the LDA's and CSU's. The Public Land Survey System (PLSS) was used for all of the state parcels and several of the federal parcels. The previous LDA's coverage (prior to 2000), was automated at a section level. This dataset delineates the boundaries based on the exact legal description. Special notes about LDA's - The legislature may designate an area for special uses. Areas designated by the legislature may include refuges, sanctuaries, critical habitat areas, ranges, special management areas, forests, parks, recreation areas, preserves, public use areas, recreation rivers, and recreational mining areas. Consult the referenced Alaska Statutes to determine the legal description and special management intent of any particular area. Many areas also have regulations and plans that govern uses within their boundaries. State Wildlife Areas - Includes Sanctuaries, State Range Areas, Critical Habitat Areas and Refuges. They are established under Title 16, Chapter 20 of the Alaska Statutes to protect and preserve the natural habitat and game population or to enhance habitat for particular wildlife species. Most of these areas are managed by the Alaska Department of Fish and Game. State Park Areas - Includes parks, marine parks, recreation areas, state preserves, and special management areas. They are established under Title 41, Chapter 21 of the Alaska Statutes to foster the growth and development of a system of parks and recreational facilities and opportunities in the state, for the general health, welfare, education, and enjoyment of its citizens and for the attraction of visitors to the state. Most of these areas are managed by the Department of Natural Resources, Division of Parks and Outdoor Recreation. State Forest Areas - Includes state forests and resource management areas. They are established under Title 41, Chapter 15 or Chapter 17 of the Alaska Statutes primarily for management of forest resources. These areas are managed by the Department of Natural Resources, Division of Forestry. Other State Multiple Use Areas - Includes public use areas, recreation rivers, and recreational mining areas. They are established under Title 41, Chapter 23 of the Alaska Statutes for special multiple use management of state public land and water resources by the Department of Natural Resources and management of public wildlife resources by the Department of Fish and Game.North Slope Science Initiative (NSSI) extracted ANWR boundaries as a separate file from DNR Administrative Large Parcels shapefile (2018).
