Elk Bruneau Diamond Herd

The Bruneau elk herd comprises part of an Idaho–Nevada metapopulation that primarily uses winter ranges in Idaho and summer ranges in Nevada. Divergent migration patterns separate two subherds comprising the Bruneau-Diamond A Desert herd: the J-P Desert subherd and the Diamond Desert subherd. Although the two subherds occupy independent summer ranges, they converge on common wintering grounds that are separated by the Bruneau River canyon near the confluence of the Bruneau and Jarbidge Rivers. Through coordination among Idaho, Nevada, and the Shoshone-Paiute Tribes of the Duck Valley Reservation, Nevada, the Bruneau-Diamond A elk herd remains a stable population. This layer's data were collected as part of a project conducted between 2015 and 2022. This dataset was derived from two separate datasets for the Bruneau Diamond herd obtained via ScienceBase: Stopovers and Migration Routes. Due to the need to merge these datasets for visualization purposes, the “Contour” field was standardized to account for discrepancies among the source datasets. Rather than retaining a numeric value (e.g., 10) in the “Contour” field, stopover features were assigned the value “stopover.” This change was made because the “Contour” field is used across elk datasets for symbology and legend labeling, and these values are more easily interpreted at a glance. For an explanation of the original contour values of 10 for stopover see the attribute definitions table Attributes (not all field definitions may be listed): ───────┬────────────┬──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Contour│ │We delineated 1 individual, low, medium and high-level migration routes from population level utilization distributions of animal movements. ───────┼────────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── │Stopover │Stopovers were defined as the areas representing the highest 10 percent of use from the mean population-level UD. ───────┼────────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── │1 individual│Used by 1 individual ───────┼────────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── │Low │Used by two individuals to 10 percent of the individuals. ───────┼────────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── │Medium │Used by 10–20 percent of the individuals. ───────┼────────────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── │High │Used by >20 percent of the individuals. ───────┴────────────┴────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
Elk Y P Desert Herd

The Y P Desert elk herd comprises part of an Idaho-Nevada metapopulation that primarily uses a winter range in Idaho and a summer range in Nevada. Y P Desert elk follow an east-to-west migration along the South Fork Owyhee River onto the Y P Desert in Idaho and Nevada during the winter. Like many ungulate winter ranges in western Elko County, wildfires also affect the Y P Desert, where cheatgrass, mustard, various Cirsium spp. (thistle) species, and medusahead rye have invaded priority habitat. However, large expanses of sagebrush and native bunch grasses, such as basin wildrye and Idaho fescue, remain on the landscape. Growth for this herd is limited by hunter harvest, which is currently guided by population objectives outlined in the “Western Elko County Elk Management Sub-Plan” (Western Elko County Elk Management Working Group, 2003). This layer's data were collected as part of a project conducted between 2014 and 2020. This dataset was derived from two separate datasets for the Y P Desert herd obtained via ScienceBase: Stopovers and Migration Routes.

Lahontan cutthroat trout Occupied Streams NV

This layer includes in-basin and out-of-basin (Lahontan basin) LCT populations, excluding recreational streams (systems that are stocked exclusively for angling and not for conservation purposes). The attribute table includes all fields associated with the most recent version of the National Hydrography Dataset. There is also a Pop_Name field to define given LCT populations, as not all populations perfectly correlate with the GNIS_Name field in nomenclature and/or spatial distribution. In addition, the Intercon_Na field defines interconnected LCT populations (metapopulations) where applicable. This is a living layer that is subject to change as data emerges over field seasons, eDNA results, etc. This layer was created by the USFWS in partnership with field biologists across the range of LCT, to include biologists from NDOW, CDFW, ODFW, TU, and Tribal entities. LCT related data and project can be access via : https://www.conservationefforts.org/cutr/home/

Human Modification_tiled

Data on the extent, patterns, and trends of human land use are critically important to support global and national priorities for conservation and sustainable development. To inform these issues, we created a series of detailed global datasets for 1990, 1995, 2000, 2005, 2010, 2015, and 2017 to evaluate temporal changes and spatial patterns of land use modification of terrestrial lands (excluding Antarctica). These data were calculated using the degree of human modification approach that combines the proportion of a pixel of a given stressor (i.e. footprint) times the intensity of that stressor (ranging from 0 to 1.0). Our novel datasets are detailed (0.09 km^2 resolution), temporally consistent (for 1990-2015, every 5 years), comprehensive (11 change stressors, 14 current), robust (using an established framework and incorporating classification errors and parameter uncertainty), and strongly validated. We also provide a dataset that represents ~2017 conditions and has 14 stressors for an even more comprehensive dataset, but the 2017 results should not be used to calculate change with the other datasets (1990-2015). The original values of the datasets ranged from 0.0 to 1.0, where 0.0 is no human modification and 1.0 is full or complete human modification. These values were represented as 32-bit floating point values, but were converted to a 16-bit integer to reduce file size, by multiplying by 32767. Original datasets were in EPSG 3857 coordinates and the extent of longitude/latitude is -180, -75, 180, 85. The Nevada Department of Wildlife clipped this layer to Nevada and converted it back to a 32-bit floating point, and converted vales back to a 0 to 1 scale. See Theobald, David et al.

Sagebrush Ecosystem Integrity 2017 - 2020 NV

These data were compiled as a part of a landscape conservation design effort for the sagebrush biome, and are the result of applying a spatially explicit model that assessed geographic patterns in sagebrush ecological integrity and used these results to identify Core Sagebrush Areas (CSAs), Growth Opportunity Areas (GOAs), and Other Rangeland Areas (ORAs). Our overall objective in this study was to characterize geographic patterns in ecological integrity of sagebrush ecosystems. These data represent the estimated integrity of sagebrush ecosystems, estimated from a spatial model that assigns high integrity is areas with abundant big sagebrush and perennial grass/forb cover and with minimal annual grass/forb cover, minimal conifers, and minimal human modification. This spatial model was applied over the entire sagebrush biome for several time periods and were estimated for 5 historical time periods between 1998 and 2020, and for one future time period (2030-2060). For each time period, input data were derived from satellite imagery, and the spatial model used those input values to estimate sagebrush ecological integrity. This approach to estimating ecological integrity was developed by consultation with experts from across the biome, allowing for the relationship between integrity and plant cover to vary among regions, as described in Doherty et al (2022). These data can be used to inform and prioritize conservation and restoration efforts across the sagebrush biome.

Bighorn Sheep Movement Corridors

Polygons represent distribution of current bighorn sheep herds in some situations by season of use and potential bighorn sheep habitat that is currently unoccupied based on the best available information that includes aerial surveys of bighorn sheep, opportunistic bighorn sheep observations from all credible sources, various forms of bighorn sign, and keen understanding of bighorn habits and life cycle needs in relation to existing geographic and habitat features. Unoccupied habitat is also based on historic accounts of bighorn sheep prior to most herds being extirpated in the early 1900's.
