This dataset is a compilation of species ranges gathered from various sources. Many of these ranges were created by IDFG using methodologies similar to those employed in the NW ReGAP or the HUC5 observation effort. Species ranges provide a general representation of where a species might occur during its lifetime. It's important to distinguish these from species 'distribution models,' which pinpoint potential habitat within the range.These ranges were constructed using the best available data and can estimate potential occurrences. To use this data effectively, users can apply a definition query in ArcGIS to visualize specific species ranges. For the most straightforward download, viewing, or filtering of the dataset, it's recommended to bring the API REST service into ArcGIS Pro. Keep in mind that due to the dataset's size, the Open Data Site download might experience timeouts, particularly with a large number of ranges. If you opt to use the Open Data Site, follow the directions by clicking on this LINK.Species range models were compiled initially for use within an online map service to depict species range for species within the 'Idaho Species Catalog',https://idfg.idaho.gov/speciesIdaho species range models compiled and/or created by the Idaho Department of Fish and Game, Idaho Fish and Wildlife Information System. Data pulled 18 December 2023, edits are ongoing as needed.

This analysis uses location data collected on mule deer that were fitted with GPS collars in Idaho for 2003 – 2019. Individuals using a winter range (as defined as a winter herd), were used for the analysis if their location data was available at the time of the analysis. Each individual’s location dataset is used to estimate winter and summer ranges, and seasonal spring and fall migration using net-squared displacement techniques (Bunnefeld et al. 2011). Fall and spring migration locations are used for the migration route analysis. After individual mule deer spring and fall migration locations are determined, a Brownian Bridge Movement Model (BBMM, Horne et al. 2007) is used to estimate the individuals Utilized Distribution (UD) during the seasonal migrations. Depending of the frequency of the location data, either a BBMM or a Forced Motion Variance model (FMV) are used as an estimate of that season’s migration UD. If locations collected at a < 7hr schedule, the migration used BBMM modeling techniques. If the schedule was greater than 7 hrs a FMV modeling technique was used (Fatteberge et al, in review). Further, FMV techniques that allowed for a 14 hour gap in location schedule were preferred over FMV models that used a maximum of 27 hr gap. When an individual had several seasonal migrations, the resulting UDs distributions are combined and averaged to create a single UD of all the seasonal migrations conducted by that individual. Individual UDS are then combined for all individuals in the winter herd with available UD information. For migration routes, the following classes were delineated based on the area’s use across the winter herd, used by 1 individual, used by 2individuals to 10% of the winter herd, 10 to 20% use of the winter herd, and greater than 20% use by the winter herd. The combined individual UDS are aggregated to estimate winter herd stopover locations. From the combined winter herd UD, the top 10% of recorded values are selected to represent population level stopoversNorth Fork of Salmon River Mule Deer Migration StatisticsAnalyzed/Prepared by: Jodi Berg and Scott BergenSeptember 2020Spatial MetricsAverage length of Migration: 33.406 milesMaximum Migration Length: 64.548 milesMinimum Migration Length: 8.976 milesTotal Migrations Analyzed: 31Total Number of Individuals: 16Total Number Spring Migrations: 20Total Number Fall Migrations: 11Of 31 individual seasonal migrations, 1 used Brownian bridge movement models with an 8-hour time-lag, 11 used forced motion variance (1400 m) models with a 14-hour time-lag, and 19 used force motion variance (1400 m) models with a 27-hour time-lag.Temporal Data Extent of Study: May 10, 2013 – October 29, 2018Spring MigrationFall MigrationStart Date AverageApril 28September 26 Minimum March 29September 4 MaximumJune 20October 19End Date AverageMay 24October 29 MinimumMay 8October 10 MaximumJuly 13January 22Duration Average1933 Minimum53 Maximum4083Migration Use Class StatisticsUse ClassAcres 1 individual303,562 Low (>2 individuals)-- Medium (10-20%)70,498 High (>20%)6,548 Stopover24,759

Between August 30 and December 1, in the depicted GMUs, hunters may use motorized vehicles only on established roadways that are open to motorized traffic and capable of beingtraveled by full-sized automobiles. The rule is now specific only to hunting of big game animals, including moose, bighorn sheep and mountain goat. The rule no longer applies to hunting of upland game birds or upland game animals.

The Owinza mule deer herd summers in higher elevation habitats in the Pioneer and Soldier Mountains, as well as Craters of the Moon National Preserve (Figure 1). Starting in spring, this herd will start to migrate from ‘terminal’ winter range through portions of the big desert near Owinza and Sid Butte towards higher elevation habitats within the Sawtooth National Forest surrounding the Big Wood River Valley. In autumn, the Owinza mule deer herd seasonally migrates toward lower elevation habitats. Within this herd, some mule deer will migrate towards terminal winter range south of Perine, whereas others will hold on winter range between the Picabo Hills and northeast of Dietrich. When winter snows start to accumulate, these holdover individuals will move further to the south towards terminal winter range. Often these winter movements will not occur until January or February and are over 50 miles in straight-line distance. About one-fifth of the Owinza mule deer winter herd use this type of winter movement strategy to complete their annual life history.

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 processing 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. Field edits started with the Alt E map from DEIS (State of Idaho’s Alternative) as a baseline and were completed in December 2013. In subsequent discussions, the State and FWS Idaho Fish and Wildlife Office, expressed concerns about adding more areas to Core designation especially if outside the FWS PACs which were delineated prior to release of the DEIS. The final map used for the Proposed Plan reflects Management Zones (M.Z.s) delineations following multiple discussions between, BLM, FS, FWS and the State. Some additional areas in south central Idaho, Mountain Home, and Weiser area were added as GHMA, which are not reflected in the Alt D or E map. These were typically annual grassland areas from the Key Habitat Map that had been previously excluded from the initial PPH/PGH model. These areas have restoration potential or involve past or ongoing restoration efforts. “Donut holes” of less than 500 acres located inside a larger matrix were classified the same as the surrounding matrix. Snapping of PHMA, IHMA, or GHMA to meaningful edges or features (canyons, allotment/pasture boundaries, roads etc.) was completed at the field level to facilitate use of the map designations at the field level. Specific changes can be viewed in MapEditsSummary_05232014_Final.docx, see metadata properties for the attachment

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.

This analysis uses location data collected on elk that were fitted with GPS collars in Idaho for 2007 – 2019. Individuals using a winter range (as defined as a winter herd), were used for the analysis if their location data was available at the time of the analysis. Each individual’s location dataset is used to estimate winter and summer ranges, and seasonal spring and fall migration using net-squared displacement techniques (Bunnefeld et al. 2011). Fall and spring migration locations are used for the migration route analysis. After individual elk spring and fall migration locations are determined, a Brownian Bridge Movement Model (BBMM, Horne et al. 2007) is used to estimate the individuals Utilized Distribution (UD) during the seasonal migrations. Depending of the frequency of the location data, either a BBMM or a Forced Motion Variance model (FMV) are used as an estimate of that season’s migration UD. If locations collected at a less than 7hr schedule, the migration used BBMM modeling techniques. If the schedule was greater than 7 hrs a FMV modeling technique was used (Fatteberge et al, in review). Further, FMV techniques that allowed for a 14 hour gap in location schedule were preferred over FMV models that used a maximum of 27 hr gap.

Feature service contains watershed ecological groups and ecological zones along with related tables containing functional wetland data and wetland mitigation restoration guidance.

The Sheeprocks (UT) was revised to resync with the UT habitat change as reflected in the Oct 2017 habitat data, creating the most up-to-date version of this dataset. Data submitted by Wyoming in February 2018 and by Montana and Oregon in May 2016 were used to update earlier versions of this feature class. The biologically significant unit (BSU) is a geographical/spatial area within Greater Sage-Grouse habitat that contains relevant and important habitats which is used as the basis for comparative calculations to support evaluation of changes to habitat. This BSU unit, or subset of this unit is used in the calculation of the anthropogenic disturbance threshold and in the adaptive management habitat trigger. BSU feature classes were submitted by individual states/EISs and consolidated by the Wildlife Spatial Analysis Lab. They are sometimes referred to as core areas/core habitat areas in the explanations below, which were consolidated from metadata submitted with BSU feature classes. These data provide a biological tool for planning in the event of human development in sage-grouse habitats. The intended use of all data in the BLM's GIS library is to support diverse activities including planning, management, maintenance, research, and interpretation. While the BSU defines the geographic extent and scale of these two measures, how they are calculated differs based on the specific measures to reflect appropriate assessment and evaluation as supported by scientific literature.There are 10 BSUs for the Idaho and Southwestern Montana GRSG EIS sub-region. For the Idaho and Southwestern Montana Greater Sage-Grouse Plan Amendment FEIS the biologically significant unit is defined as: a geographical/spatial area within greater sage-grouse habitat that contains relevant and important habitats which is used as the basis for comparative calculations to support evaluation of changes to habitat. Idaho: BSUs include all of the Idaho Fish and Game modeled nesting and delineated winter habitat, based on 2011 inventories within Priority and/or Important Habitat Management Area (Alternative G) within a Conservation Area. There are eight BSUs for Idaho identified by Conservation Area and Habitat Management Area: Idaho Desert Conservation Area - Priority, Idaho Desert Conservation Area - Important, Idaho Mountain Valleys Conservation Area - Priority, Idaho Mountain Valleys Conservation Area - Important, Idaho Southern Conservation Area - Priority, Idaho Southern Conservation Area - Important, Idaho West Owyhee Conservation Area - Priority, and Idaho West Owyhee Conservation Area - Important. Raft River : Utah portion of the Sawtooth National Forest, 1 BSU. All of this areas was defined as Priority habitat in Alternative G. Raft River - Priority. Montana: All of the Priority Habitat Management Area. 1 BSU. SW Montana Conservation Area - Priority. Montana BSUs were revised in May 2016 by the MT State Office. They are grouped together and named by the Population in which they are located: Northern Montana, Powder River Basin, Wyoming Basin, and Yellowstone Watershed. North and South Dakota BSUs have been grouped together also. California and Nevada's BSUs were developed by Nevada Department of Wildlife's Greater Sage-Grouse Wildlife Staff Specialist and Sagebrush Ecosystem Technical Team Representative in January 2015. Nevada's Biologically Significant Units (BSUs) were delineated by merging associated PMUs to provide a broader scale management option that reflects sage grouse populations at a higher scale. PMU boundarys were then modified to incorporate Core Management Areas (August 2014; Coates et al. 2014) for management purposes. (Does not include Bi-State DPS.) Within Colorado, a Greater Sage-Grouse GIS data set identifying Preliminary Priority Habitat (PPH) and Preliminary General Habitat (PGH) was developed by Colorado Parks and Wildlife. This data is a combination of mapped grouse occupied range, production areas, and modeled habitat (summer, winter, and breeding). PPH is defined as areas of high probability of use (summer or winter, or breeding models) within a 4 mile buffer around leks that have been active within the last 10 years. Isolated areas with low activity were designated as general habitat. PGH is defined as Greater sage-grouse Occupied Range outside of PPH. Datasets used to create PPH and PGH: Summer, winter, and breeding habitat models. Rice, M. B., T. D. Apa, B. L. Walker, M. L. Phillips, J. H. Gammonly, B. Petch, and K. Eichhoff. 2012. Analysis of regional species distribution models based on combined radio-telemetry datasets from multiple small-scale studies. Journal of Applied Ecology in review. Production Areas are defined as 4 mile buffers around leks which have been active within the last 10 years (leks active between 2002-2011). Occupied range was created by mapping efforts of the Colorado Division of Wildlife (now Colorado Parks and Wildlife –CPW) biologists and district officers during the spring of 2004, and further refined in early 2012. Occupied Habitat is defined as areas of suitable habitat known to be used by sage-grouse within the last 10 years from the date of mapping. Areas of suitable habitat contiguous with areas of known use, which do not have effective barriers to sage-grouse movement from known use areas, are mapped as occupied habitat unless specific information exists that documents the lack of sage-grouse use. Mapped from any combination of telemetry locations, sightings of sage grouse or sage grouse sign, local biological expertise, GIS analysis, or other data sources. This information was derived from field personnel. A variety of data capture techniques were used including the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing atvarious scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). Update August 2012: This dataset was modified by the Bureau of Land Management as requested by CPW GIS Specialist, Karin Eichhoff. Eichhoff requested that this dataset, along with the GrSG managment zones (population range zones) dataset, be snapped to county boundaries along the UT-CO border and WY-CO border. The county boundaries dataset was provided by Karin Eichhoff. In addition, a few minor topology errors were corrected where PPH and PGH were overlapping. Update October 10, 2012: NHD water bodies greater than 100 acres were removed from GrSG habitat, as requested by Jim Cagney, BLM CO Northwest District Manager. 6 water bodies in total were removed (Hog Lake, South Delaney, Williams Fork Reservoir, North Delaney, Wolford Mountain Reservoir (2 polygons)). There were two “SwampMarsh” polygons that resulted when selecting polygons greater than 100 acres; these polygons were not included. Only polygons with the attribute “LakePond” were removed from GrSG habitat. Colorado Greater Sage Grouse managment zones based on CDOW GrSG_PopRangeZones20120609.shp. Modified and renumbered by BLM 06/09/2012. The zones were modified again by the BLM in August 2012. The BLM discovered areas where PPH and PGH were not included within the zones. Several discrepancies between the zones and PPH and PGH dataset were discovered, and were corrected by the BLM. Zones 18-21 are linkages added as zones by the BLM. In addition to these changes, the zones were adjusted along the UT-CO boundary and WY-CO boundary to be coincident with the county boundaries dataset. This was requested by Karin Eichhoff, GIS Specialist at the CPW. She provided the county boundaries dataset to the BLM. Greater sage grouse GIS data set identifying occupied, potential and vacant/unknown habitats in Colorado. The data set was created by mapping efforts of the Colorado Division of Wildlife biologist and district officers during the spring of 2004, and further refined in the winter of 2005. Occupied Habitat: Areas of suitable habitat known to be used by sage-grouse within the last 10 years from the date of mapping. Areas of suitable habitat contiguous with areas of known use, which do not have effective barriers to sage-grouse movement from known use areas, are mapped as occupied habitat unless specific information exists that documents the lack of sage-grouse use. Mapped from any combination of telemetry locations, sightings of sage grouse or sage grouse sign, local biological expertise, GIS analysis, or other data sources. Vacant or Unknown Habitat: Suitable habitat for sage-grouse that is separated (not contiguous) from occupied habitats that either: 1) Has not been adequately inventoried, or 2) Has not had documentation of grouse presence in the past 10 years Potentially Suitable Habitat: Unoccupied habitats that could be suitable for occupation of sage-grouse if practical restoration were applied. Soils or other historic information (photos, maps, reports, etc.) indicate sagebrush communities occupied these areas. As examples, these sites could include areas overtaken by pinyon-juniper invasions or converted rangelandsUpdate October 10, 2012: NHD water bodies greater than 100 acres were removed from GrSG habitat and management zones, as requested by Jim Cagney, BLM CO Northwest District Manager. 6 water bodies in total were removed (Hog Lake, South Delaney, Williams Fork Reservoir, North Delaney, Wolford Mountain Reservoir (2 polygons)). There were two “SwampMarsh” polygons that resulted when selecting polygons greater than 100 acres; these polygons were not included. Only polygons with the attribute “LakePond” were removed from GrSG habitat. Oregon submitted updated BSU boundaries in May 2016 and again in October 2016, which were incorporated into this latest version. In Oregon, the Core Area maps and data were developed as one component of the Conservation Strategy for sage-grouse. Specifically, these data provide a tool in planning and identifying appropriate mitigation in the event of human development in sage-grouse habitats. These maps will assist in making
