Greater Sage Grouse Conservation Areas
Idaho Department of Fish and Game

This data set contains landscape-scale greater sage-management zones as defined by the Idaho Sage Grouse Task Force. The intended scale of use is 1:500,000. The data was developed through a collaborative process in looking at several GIS datasets. The dataset was digitzed coarsely on the screen to roughly match the extent of the BLM PPH and PGH line work. In August 2012, the names of the Southwest and Southeast Conservation Areas where changed to West Owyhee and Southern, respectively. Also, the boundary between these two areas was also changed to the Bruneau River. fields: Management Zones are within field [IDcat_rev1] = Core, Important, General, or Nonhabitat (areas that are islands of nonhabitat)Conservation Areas are within field [CoreZones] = Mountain Valleys, Desert, Southern, or West Owyhee.[NorthSouth] = South of the Snake River or North of the Snake River

Idaho and South Western Montana Greater Sage Grouse Conservation Areas
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

Idaho-Montana Greater Sage-Grouse Conservation Areas for the Idaho and Southwestern Greater Sage-Grouse (GRSG) Environmental Impact Statement (EIS). The Conservation Areas are seamless and cover the extent of the Idaho-SW Montana GRSG EIS. They include non-habitat as well as habitat/Sage-Grouse Management areas identified in all alternatives. The Sage-grouse Conservation Areas are intended to be used for summarizing sage-grouse habitat and form the geographic basis for evaluating disturbance density and adaptive management strategies. The Idaho Governor's Conservation Areas were used as the foundation for this layer.

The initial boundaries delineated in the Idaho Governor's Conservation areas were expanded to include all lands within the Idaho-SW Montana GRSG EIS boundary, as well as the area in Utah managed by the Sawtooth National Forest, and the area within the Dillon and Butte BLM Field Offices in SW Montana. The area in Utah was merged with the Idaho Southern Conservation Area. The area in SW Montana was grouped as the Southwestern Montana Conservation Area. The Idaho Governor's Conservation Areas were based on Alternative E Habitat. These areas were expanded to include all Greater Sage-Grouse habitat / Greater sage-grouse management areas identified in any of the alternatives, as well remaining areas outside those areas within the Idaho-SW Montana GRSG EIS. Features such as rivers and roads were used to split those areas so that they could be merged with the Conservation Area

There are five Greater Sage-Grouse Conservation Areas in the EIS boundary: Idaho Mountain Valleys Conservation Area, Idaho Desert Conservation Area, Idaho Southern Conservation Area, Idaho West Owyhee Conservation Area, and the Southwestern Montana Conservation Area. The area in Utah managed by the Sawtooth National Forest was grouped with the Idaho Southern Conservation Area. The areas in Southwestern Montana were grouped as the Southwestern Montana Conservation Area.

The Mountain Valleys Conservation Area is located north of the Snake River, and includes the Sage-grouse West-Central population area. It extends west from Rexburg, north and west of Highway 33 to Howe, north and west of Highway 33/22 to Arco, north and west of Highway 26/20/93 to Carey, north and west of Highway 20 to Hill City, north and west of Highway 20 to the Dylan Karaus Road, west to Canyon Creek. Canyon Creek to the confluence with the Snake River form the western boundary of the Mountain Valleys Conservation Area.

The Desert Conservation area is located north of the Snake River and south of the Mountain Valleys Conservation Area. It extends from the confluence of the Canyon Creek and Snake RIvers, eastward to Idaho Falls. The Snake River and Henry's Fork form the eastern boundary of the Desert Conservation Area.

The West Owyhee Conservation Area is located south of the Snake River and west of the Bruneau River.

The Southern Conservation Area is located south of the Snake River and east of the Bruneau River, including East Idaho Uplands and Bear Lake Plateau, and the area in Utah managed by the Sawtooth National Forest.

Southwestern Montana Conservation Area is located in southwestern Montana, encompassing the BLM Dillon and Butte Field Offices.

Greater Sage-Grouse Habitat Management Areas of the Great Basin Region, Idaho-SW Montana Sub-region, Greater Sage-grouse Environmental Impact Statement (EIS) - Administrative Draft Proposed Plan, as updated for inclusion of Sage brush Focal Areas.
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

Greater Sage-Grouse Management Areas (habitat) in the Proposed Plan of the Great Basin Region, Idaho-SW Montana Sub-region, Greater Sage-grouse Environmental Impact Statement (EIS) as Priority, Important, and General. Management Areas were delineated by BLM, U.S. Forest Service, State of Idaho and the U.S. Fish and Wildlife Service based on considerations of sage-grouse occupancy, landscape, habitat and land use/adaptive management opportunities.This data was developed as the Administrative Draft Proposed Plan (ADPP). for the Great Basin Region, Idaho-SW Montana Sub-region, Greater Sage-grouse (Centrocercus urophasianus) Environmental Impact Statement (EIS). This layer was edited 5/7/2015 at the WO direction to add three areas of non-habitat in the Sagebrush Focal Areas as PHMA. See procesing steps.Priority Habitat Management Areas (PHMA) have the highest conservation value based on various sage-grouse population and habitat considerations and reflect the most restrictive management designed to promote sage-grouse conservation. Important Habitat Management Areas (IHMA) are closely aligned with PHMA, but management is somewhat less restrictive, providing additional management flexibility. The General Habitat Management Areas (GHMA) designation is the least restrictive due to generally lower occupancy of sage-grouse and more marginal habitat conditions.A decision was made in September 2014 by the Washington Office that all sub-regions would use a consistent naming convention for identifying Habitat Management Areas (HMA). These are Priority Habitat Management Area (PHMA) and General Habitat Management Area (GHMA). The Idaho and Southwestern Montana sub-region has an additional HMA identified as Important Habitat Management Area (IHMA). Attributes in this layer were updated 9/26/2014. Core updated to PHMA, Important updated to IHMA, and General updated to GHMA.The layer was renamed from ManagementZones_Alt_G_05272014_Final to ManagementAreas_Alt_G_05272014_final. The field identifying the Management Areas was renamed from Management_Zone to Habitat_Management_Area.ManagementAreas_Alt_G_05272014_final renamed to Habitat_ADPP on 01212015

Greater Sage-Grouse (Centrocercus urophasianus) Nesting and Late Brood Rearing Habitat for the Idaho and Southwestern Montana GReater Sage-Grouse Final Environmental Impact Statement
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

Greater Sage-Grouse (Centrocercus urophasianus) nesting and late brood rearing habitat for the Idaho and Southwestern Montana Greater Sage-Grouse Final Environmental Impact Statement (FEIS). For purposes of the analysis, it is defined as the extent of mapped nesting habitat derived by the use of a 10 km (6.2 mile) buffer around active leks to capture approximately 80% of nests (Connelly et. al 2013; Idaho Department of Fish and Game (IDFG) 2012 unpublished data, Montana BLM Dillon Field Office 2014 unpublished data; and U.S. Forest Service 2014 unpublished data). Breeding habitat is inclusive of lek, nesting, and early brood-rearing habitat (Connelly et. al 2000). Late brood-rearing (i.e. summer) habitat has not been mapped in detail for the Idaho and Southwestern Montana Subregion (IDMT), but it is assumed for purposes of the analysis, that these areas are largely encompassed by and embedded within the mapped or estimated nesting habitat areas. Buffered Lek data for Idaho, Montana (Dillon Field Office), and the Raft River Unit of the Sawtooth National Forest in Utah were combined to create this layer. For Idaho, the portion of winter habitat that overlaps nesting habitat is included in this data.See procesing steps.

Greater Sage-grouse Habitat 2012 - Dissolved (Polygon)
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

This version of the 2012 data has been dissolved on the habitat class field and was created as multipart polygons to make it easier for the public to use.

This data set contains simple, landscape-scale greater sage-grouse habitat types for Idaho and constitutes a current approximation of sage-grouse habitat in the state. The data can be used for general conservation and restoration planning purposes, but additional data or field verification are needed for applications at finer scales. The habitat types include: (1) key sage-grouse habitat areas and (2) four habitat restoration types: (a) R1 - perennial native and non-native grasslands with high restoration potential; (b) R2 - annual grass dominated areas (either shrubland or grassland) with low restoration potential; (c) R3 - conifer encroachment areas with high restoration potential and (d) RB - areas that have recently burned and the type of habitat that is coming back and its restoration potential has not yet been determined. A new data set will be developed annually to update the planning map and chart landscape-level changes in sage-grouse habitat over time. Edits may also document refinements discovered through inventory, monitoring and modeleing. This data covers all of Idaho and a small area in Nevada that is managed by Idaho BLM. Intended scale of use is 1:100,000.

In addition to this version of the 2012 greater sage-grouse habitat, the undissolved version is also available from the Bureau of Land Management (BLM) - see Originator contact information. The undissolved update includes an area in the vicinity of Oreana in the Owyhee Field Office, Boise District, that was modeled to produce a more refined and detailed vegetation description. The model used Landsat 7 ETM+ data (2002) for characterization of sagebrush steppe/juniper woodland. Specifically, it refined Key habitat and shows where Key habitat is being encroached by juniper.

This dataset is not synonomous with BLM's "Preliminary Prioirty Hbitat" or "Preliminary General Habitat" mapping efforts, as those incorporate additional habitat and sage-grouse population data or models.

BLM Idaho Greater Sage-grouse Habitat 2013 - Dissolved (Polygon)
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

The 2013 Sage-grouse Habitat Planning Map update incorporates wildfire data and other edits relevant to the 2013 field and fire season as per typical processes used during the past decade. Additional areas of non-habitat, such as paved highways, municipal boundaries, water bodies etc., were also removed. However, the map extent for sage-grouse key habitat and potential restoration areas should be considered provisional, contingent on the final outcome of additional analyses currently underway in association with the national Greater Sage-grouse Conservation Strategy.

Greater Sage-grouse Habitat 2007 (Polygon)
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

These data sets contain simple, landscape-scale greater sage-grouse habitat types that can be used for conservation and restoration planning purposes. The habitat types include: (1) key sage-grouse habitat areas and (2) three habitat restoration types: (a) R1 - perennial native and non-native grasslands with high restoration potential; (b) R2 - annual grass dominated areas (either shrubland or grassland) with low restoration potential and (c) R3 - conifer encroachment areas with high restoration potential. The initial data set delineates these habitat types up to the year 2000 (2000 Northern Sage-Grouse Habitat Planning Map). This baseline map was developed using field experts with Idaho BLM, Idaho Department of Fish and Game (IDFG) and other local experts. Existing vegetation, fire history and sage grouse population data were used to delineate the habitat types. A subsequent data set (2002 Northern Sage-Grouse Planning Map) was also developed for the year 2002 and reflects changes in these habitats as a result of fires, emergency fire rehabilitation (EFR) and restoration efforts during 2000 and 2001. Fire polygon and project descriptions for EFRs and restoration projects were used to map habitats for the 2002 map (please see process step for detailed information on the original capture of the sage-grouse habitat data). A new data set was generated in 2004, reflecting fire polygons from 2002 and 2003. For the 2005 update BLM field offices submitted edits based on new information from monitoring and inventory data, fire occurrence and treatments from the 2005 season. IDFG digitized some polygons (particularly in the West Central SGPA) from NAIP imagery to increase the data accuracy. For the 2006 update BLM field offices submitted edits based on new information from monitoring and inventory data, fire occurrence and treatments from the 2006 season. IDFG has not submitted edits. USFS supplied fire polygons for updating the habitat that were already provided by BLM-IF so no further edits were made. For the 2007 edits, each BLM District submitted a seperate habitat dataset that included their edits. All the districts edited the same version of habitat that they copied from the Idaho State Office server. USFS also submitted edits based on 2007 fires, but none of these edits were new compared to what the BLM Districts submitted. A new data set will be developed annually to update the planning map and chart landscape-level changes in sage-grouse habitat over time.

Sagebrush Focal Areas 20150501, Idaho-SW Montana Sub-region, Greater Sage-grouse Environmental Impact Statement (EIS)
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office

Sagebrush Focal Areas (SFAs) are a refinement of Greater Sage Grouse habitat delineating the most valuable habitat to the Greater Sage Grouse (Centrocercus urophasianus). They are a subset of the "Highly Important Landscapes" identified by the US Fish and Wildlife Service October, 2014. This dataset is a further refinement of the data layer, "SFA_Draft_January_2015_DIS" released by the Bureau of Land Management (BLM) National Operations Center (NOC) in January, 2015. The SFAs were identified to further protect highly valuable sage grouse habitat and develop conservation strategies as described in the Administrative Draft Proposed Plan (ADPP) for the Idaho and Southwestern Montana Greater Sage Grouse Environmental Impact Statement. Areas within SFAs will be managed as Priority Habitat Management Areas (PHMA) and may include areas of non-habitat. The lineage section describes the processing that was done to the, "SFA_Draft_January_2015_DIS" layer. No SFA was delineated in the SW Montana or USFS Raft River Unit in Utah for the Idaho and SW Montana GRSG Sub-region. Three areas of Non-Habitat managed by the BLM or USFS are included at the direction of the Washington Office. These include an area in and adjacent to the BLM Donkey Hills ACEC, approximately 12,400 acres; 4,900 acres manged by the USFS in the Lost River Range decribed as Borah Peak, and 6,800 acres of USFS manged lands described as Big Flat Top Mountain/ Copper Basin Knob.

Greater Sage-Grouse (Centrocercus urophasianus) Winter Habitat as mapped by the Idaho Department of Fish and Game (IDFG) for the Idaho and Southwestern Montana Greater Sage-Grouse Final Environmental Impact Statement (FEIS). Data is limited to Idaho. Winter was defined as December 1 - February 28. This layer includes IDFG Nesting habitat that overlaps winter habitat. See processing steps for how IDFG developed spatial data for GRSG winter habitat.

In Montana (Dillon Field Office) winter habitat use by Greater Sage-Grouse (GRSG) is highly variable due to snow pack and can change year to year. Spatial data depicting GRSG winter for the Dillon Field Office is not available. It is primarily encompasses within the Priority Habitat Management Areas. Elevation in the Raft River Unit of the Sawtooth National Forest in Utah precludes GRSG winter habitat.
