Concerns about sage-grouse habitat trends in Idaho have increased in recent years, particularly after the wildfires in eastern and south central Idaho since the latter 1990s. Sagebrush steppe vegetation mapping efforts have occurred in many areas but techniques, scales, timeframes, and resolution vary. Idaho Bureau of Land Management (BLM) and conservation partners have an ongoing need for a spatial portrayal of existing and potentially restorable sage-grouse habitat for a variety of planning purposes. At a broad scale, the Idaho BLM Greater Sage-Grouse Planning Maps and data are intended to: 1. Identify key sage-grouse habitat areas for Idaho BLM that need to be conserved. 2. Identify areas of restoration potential that should be considered during restoration planning. 3. Be a tool for land use and fire planning at the Field Office, District, and State Office levels. 4. Graphically portray the degree of sage-grouse habitat fragmentation or recovery as it changes over time. 5. Assist field staff in identifying areas where sage-grouse habitat conservation or restoration will be a primary concern and those areas where sage-grouse will not be a management emphasis. 6. Serve as an educational tool for conservation planning and public outreach. |

The 2015 Sage-grouse Habitat Planning Map update incorporates wildfire data and other edits relevant to the 2015 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. 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, but4 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. Beginning in 2015, the NA class was included to track areas that were previously identified as habitat but were removed due to vegetation type (eg. stands of existing timber on North-facing slopes) 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 modeling. 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. This dataset is not synonymous with BLM's "Preliminary Priority Habitat" or "Preliminary General Habitat" mapping efforts, as those incorporate additional habitat and sage-grouse population data or models.
