ACQ_DSP_POLY: This dataset is used for depicting Acquisitions and Disposals on maps. The history of acquisition and disposals within a BLM administrative unit or special management area is often of interest. The dataset includes both existing and proposed acquisitions and disposals. Acquisitions and disposals are intersected with natural resources and special management areas to determine impact and/or feasibility of the proposed action. This dataset is not complete for all Acquisitions and Disposals on BLM lands and, in addition, only basic information about the acquisition or disposal is provided. Details of the complete rights and restrictions history are found in the following authoritative sources: case file records, Master Title Plats (MTPs), and the Legacy Rehost 2000 (LR2000) database. The case file record is the primary source, with MTPs and LR2000 as secondary sources. Moreover, this dataset will never be complete. Over time, more and more approved ACQ_DSP features will be added to the dataset, but it will never contain the complete record (found in the case files).

OWNERSHIP_POLY: This theme portrays information related to surface jurisdiction, and land category of lands located in the states of Oregon and Washington.

ownership_poly_dissolve: This theme portrays information related to surface jurisdiction of lands located in the states of Oregon and Washington.

ownership_poly_dissolve: This theme portrays information related to surface jurisdiction of lands located in the states of Oregon and Washington.

STATUS_ARC: This theme portrays the source information for the boundaries of the parcel polygons in OWNERSHIP_POLY and SUBSURFCASE_RIGHTS_POLY.

LTZ_POLY: This feature class represents BLM Land Tenure Zones (LTZ) for Oregon and Washington, areas (zones) on BLM lands as Retention/Acquisition, Exchange, or Disposal of lands under BLM jurisdiction. The LTZ polygons do not identify actual acquisition or disposal actions, but rather the zones of potential land tenure adjustment as determined through the land use planning process. All BLM lands are covered by these zones. For detailed information on individual parcels contact the relevant BLM Oregon district staff. This data conforms to the 'Land Tenure Zones Spatial Data Standard 20131130. 'http://www.blm.gov/or/datamanagement/index.php'

SUBSURFACE_RIGHTS_POLY: This theme portrays information related to the Public Land Survey System, and subsurface minerals of lands in the states of Oregon and Washington.

RMA_PUB_POLY: This dataset describes the area of established BLM Recreation Management Areas (RMA). RMA data is created through the planning process and exists as a Special Management Area within the Oregon Data Framework (SMA). This data is subject to change without notification. For complete and current documentation of this data please see the 'Resource Management Areas' data standard located here http://www.blm.gov/or/datamanagement/index.php.

MINSTIP_POLY: This dataset applies to BLM-administered lands containing valuable minerals and categorized in the U.S Code of Federal Regulations or by official U.S. Department of Interior policy as Open, Closed, or Restricted to mining or leasing. And it further labels restrictions, if any, by type (e.g., seasonal, no surface occupancy, etc.). Restrictions are formalized by use of “Mineral Stipulations” as determined through the Land Use Planning Process and defined in the resultant Resource Management Plan (RMP). In addition, informal BLM email communication between Tim Barnes (OR 936.2) and Jim Perry (WO 310), dated August 9, 2013, concluded, by reference to WO IM No. 2012-044, “BLM National Greater Sage-Grouse Land Use Planning Strategy”, that RMPs developed after 2013 should also apply mineral stipulations to split estate lands (BLM subsurface jurisdiction but non-BLM surface). The three categories of minerals covered under Minerals Stipulations are: Locatable, generally the metallic and industrial minerals (subject to the General Mining Law of 1872, as amended); Leasable, generally fluid minerals (oil and gas and geothermal resources) and certain other minerals (subject to the various Mineral Leasing Acts); and Salable, generally sand and gravel (subject to mineral materials disposed of under the Materials Act of 1947, as amended). For locatable minerals, the stipulation choices for an area might be “Withdrawn” if it is withdrawn from mineral entry or “OpenWSA” if the area is open to mining claim location subject to Wilderness Study Area (WSA) Non-impairment criteria or “Open”. The stipulations choices for salable minerals are “Open” (available for mineral materials), “OpenCSU” if the area is open but with (Conditional Surface Use) special seasonal or other stipulations such as buffer zones around sage-grouse leks or archeological sites, or “Closed” (not available for mineral materials). The stipulation choices for leasable minerals are “NoLease” if the area is withdrawn or otherwise not available for leasing, “OpenCSU” if the area is open but with (Conditional Surface Use) special seasonal or other stipulations such as buffer zones around sage-grouse leks or archaeological sites, “OpenNSO” if the area is open but with No Surface Occupancy allowed or simply “Open” with standard stipulations.
