Description: These are the graphic displays of the PLSS Townships for areas recommeneded for locatable minderal withdrawal in Sagebrush Focal Areas (SFA). In the Public Land Survey System a Township refers to a unit of land, that is nominally six miles on a side, usually containing 36 sections. DISCLAIMER: No warranty is made by the BLM or FS for the use of this data. The GIS data included on this page is intended for broad planning purposes only and should not be solely relied upon for any decision making. Accuracy of the GIS is limited to the accuracy of the data available to create these layers at the time of this project. The information contained on the map is used to generally locate and identify the lands that are proposed for withdrawal in the sage brush focal areas and is for reference purposes only. They should not be construed or used as legal descriptions. Detailed maps and legal descriptions will be developed at a later date.

Description: The polygon (vector) feature class represents locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas (SFAs) in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The mineral-resources tracts are geographic areas that were assessed by the USGS and were determined to be geologically favorable for a deposit type of interest to a depth of 1 kilometer. Qualitative assessment methods outlined by the Bureau of Land Management (BLM) were used to develop tract boundaries and to assign a level of mineral-resource potential and certainty to each tract. The general process included (1) identifying possible mineral deposit types for locatable commodities specified by BLM for each focal area, (2) outlining those areas that potentially contained mineral deposits based on geology, mineral occurrences, geophysics, soil and stream-sediment geochemistry, alteration mineral assemblages inferred from satellite imagery, BLM claims and permit data, mineral-exploration activity, and existing mineral-resource assessment data, and (3) evaluating the level of mineral-resource potential and level of certainty associated with the outlined areas using BLM assessment categories. A full description of the assessment is provided in the accompanying report (Day and others, 2016). SFAs, identified by agencies of the DOI, are high-quality sagebrush habitat areas supporting high densities of breeding greater sage-grouse (Centrocercus urophasianus). SFAs are within priority habitat areas or areas where land-use measures are intended to minimize or avoid habitat disturbance. Seven SFAs are within the USGS Sagebrush Mineral-Resource Assessment Project study area. They include the Bear River Watershed, North-Central Idaho, North-Central Montana, Southeastern Oregon and North-Central Nevada, Sheldon-Hart Mountain National Wildlife Refuge Complex, Southern Idaho and Northern Nevada, and Southwestern and South-Central Wyoming SFAs, as well as additional areas in Nevada (termed the “Nevada additions”) proposed by the State of Nevada. Landscape-scale conservation efforts by the BLM, U.S. Fish and Wildlife Service (FWS), the U.S. Forest Service (USFS), State agencies, private land owners, and other partners are striving to conserve the breeding sagebrush habitat for the greater sage-grouse across these areas.

Description: The areas recommended for locatable mineral withdrawal dataset were compiled from the Bureau of Land Management (BLM) National Greater Sage-Grouse (GRSG) Conservation Strategy, which includes Environmental Impact Statements (EIS) for the revision or amendment of 98 Forest Service and BLM land use plans. Data reflect the areas of Sagebrush Focal Areas, a subset of GRSG Priority Habitat Management Areas, which are recommended for withdrawal from the Mining Law of 1872 in the Records of Decisions for the Approved Resource Management Plans and Amendments. These data were updated in April 2016 to incorporate modifications provided by the BLM Montana after reviewing the initially submitted data. Idaho also provided a revised dataset for inclusion in this consolidated file in April of 2016. Montana's April updates were provided by Renee Johnson and Randal Schardt. Idaho's April updates were provided by Jeff Cartwright and Travis Cooper. All other data were compiled from the proposed plan data.DISCLAIMER: No warranty is made by the BLM or FS for the use of this data. The GIS data included on this page is intended for broad planning purposes only and should not be solely relied upon for any decision making. Accuracy of the GIS is limited to the accuracy of the data available to create these layers at the time of this project. The information contained on the map is used to generally locate and identify the lands that are proposed for withdrawal in the sage brush focal areas and is for reference purposes only.
