This layer contains boundaries for National Designation Areas that are not included in other datasets (such as the National Landscape Conservation System (NLCS), Recreation, or Land Use Planning data standards). These are areas designated by an Act of Congress, a Presidential Executive Order, the Alaska National Interest Conservation Lands Act (ANILCA), an Order of the Secretary of the Interior, or a Public Land Order and are administered in accordance with provisions of the enabling legislation and/or orders. National Recreation Areas have at times been included with NLCS Units, but their inclusion has been questioned and Alaska has chosen to store them in this dataset. Areas established through the normal land use planning process (even if they are the same type of area) are not included in this dataset. Areas contained in Recreation (RECS) data standards- Recreation Management Zones, Extensive and Special Recreation Management Areas, are also not stored in this dataset.

This polygon feature class represents the spatial extent and boundaries of the BLM National Landscape Conservation System (NLCS) National Monuments, National Conservation Areas and Similar Designations within the BLM Administrative State of Nevada.

wsrcorr_poly: This layer is the polygon representation of the Wild and Scenic River Corridors on BLM managed lands within Oregon. The National Wild and Scenic Rivers System was created by Congress in 1968 to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition. For more information about the WSR Act, river classification, management, and links to related sites go to http://www.rivers.gov/rivers/.

WSA_POLY: This data set represents Wilderness Study Area (WSA) boundaries as inventoried in the mid1980's and defined in the October 1991 "Wilderness Study Report". Wilderness Study Areas are essentially roadless areas under BLM jurisdiction. Wilderness Study Areas have special management restrictions and priorities. They are a one-time designation and new WSA or additions to WSA are rare. For a complete description of this data consult the Wilderness Study Areas Spatial Data Standard. http://www.blm.gov/or/datamanagement/index.php

sob_poly: This theme shows the polygon representation of the jurisdictional boundary for the Bureau of Land Management State Office for Oregon and Washington.

This polygon feature class represents the spatial extent and boundaries of the BLM National Landscape Conservation System (NLCS) National Monuments, National Conservation Areas and Similar DesignationsBLM only has authority in these boudaries on identified BLM surface and subsurface lands identified on Master Title Plats.,This state dataset may have published a dataset that is more current than the National dataset; there may be geometry variations between the state and national dataset which may have different results. The national dataset is updated following the data standard schedule.

DOB_POLY: This theme shows the polygon representation of jurisdictional Bureau of Land Management Districts for Oregon and Washington.
