This raster dataset represents Places II: Specially Designated Areas of Ecological and Cultural Value within the Mojave Basin and Range. These sites represent legally protected lands and waters. Plus lands that have been identified as known recovery lands (e.g. critical habitat recommended for recovery of Desert Tortoise and recovery units identified for the CA red legged frog).
Some of the NOS rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - As a final measure of potential human impacts to the ecoregions, the impacts of current anthropogenic development are summarized in a 60 x 60 m grid by the landscape condition model (LCM). The LCM weights the relative influence of different types of human footprints based on factors like permanence, nature of the activity,...

These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - Assessing the impact of oil and gas development on vegetation and hydrology on the North Slope study area involves identifying the accumulation of effects and assessing the relative magnitude of each. Impacts on vegetation include the direct effects associated with the construction of pipelines, roads, gravel pads, and seismic...

Near-term (2020s) increases in July temperature are not expected to be significant; however significant increases are projected across 72% of the of foothills tussock tundra distribution in the long term...

Linear feature data from BLM
This layer represents the near-future scorecard of one indicator of ecosytem integrity. This ecosystem assessment is for projected 2025 landscape condtion (LCM). NatureServe’s ecological integrity framework provides a practical approach to organize criteria and indicators for this purpose (Faber-Langendoen et al. 2006, Unnasch et al. 2008). This framework provides a scorecard for reporting on the ecological status of a given CE within a given location, and if needed, facilitates the aggregation and synthesis of the component results for broader measures of ecological integrity at broader scales. Please see "cmbrCE and indicators.xlsx" for a complete list of which measures were applied to individual CEs for current...

We recommend that users snap or align rasters as best suits their own projects. - The landscape condition model evaluates the degree of human impact on the landscape. Anthropogenic activities to consider in future land-use planning may include logging and fire management. Logging has the potential to create habitat. Small clear-cuts adjacent to mature forests are ideal for the olive-sided flycatcher, as...
We analyzed 12 indicators of ecological integrity and 2 Key Ecological Attributes (KEA) to assess the current status of the Aquatic Course Filter Conservation Elements. The indicators used were: 1) Riparian Corridor Fragmentation, 2) Landscape Condition Model Index, 3) Perennial Flow Network Fragmentation by Dams, 4) Surface Water Use/Discharge Ratio, 5) Ground Water Use/Discharge Ratio, 6a) Perennial Flow Modification by Diversion Structures, 6b) Flow Modification by Dams, 7) Condition of Groundwater Recharge Zone, 8a) Atmospheric Deposition-Nitrate Loading , 8b) Atmospheric Deposition--Toxic Mercury Loading, 9) State-Listed Water Quality Impairments, 10) Sediment Loading Index, 11) Presence of Invasive Plant Species,...
Mapping of terrestrial vertebrates focuses on linking a spatial representation of species-habitat matrices to geographic distribution. Each model is a combination of distribution from regional and state references in association with contiguous appropriate habitats. Ranges for all species were based on 8-digit HUCs. Habitats were based on a raster SWReGAP 1 acre MMU land cover data set, with hydrology habitats added in from USGS NHD dataset directly or through modeling. Habitat association information was obtained from various state, regional, and national references with updates from scientific literature. This portion of the Southwest Regional Gap Analysis Project produced predicted habitat distribution maps for...
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...

Environmental variable that represents the distance to highly alkaline soils in the MBR Ecoregion.
This dataset contains points that represent known locations important for aquatic recreation, including marinas and boat ramps.
Scorecard analysis for terrestrial conservation elements and Invasive Annual Plant Species. The annual grass index represents a summary score for a CE based upon the amount of the CE itersecting the annual grass model. The summary score is a weighted mean using the following formula. ((C0*0.5+C1*0.05+C2*0.05+C3+0.1+C4*0.1+C5*0.15)/Total Count)/0.5 *where C is the cell count by category.

This simple assessment layer is used to answer management questions (MQs) about which high biodiversity sites (HBS) will experience significant climate change in the near future scenario in the Mojave Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas that have been identified by previous 3rd party analyses as having extraordinary biodiversity. It does not model actual response or condition of the HBS to climate change. Nearly all HBS in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes....
Moose (Alces americanus) are large herbivores that inhabit forests, wetlands, and riparian areas. The species is an important subsistence resource in the YKL study area. This dataset provides the most up-to-date spatial distribution of Moose (Alces americanus) calving concentrations within the YKL study area for the analysis of the Terrestrial Fine-Filter Conservation Element and Management Question #6. We heads-up digitized seasonal Moose concentrations; including calving ranges, from scanned distribution maps from the Alaska habitat management guide. During calving, rutting, and winter, moose are generally found concentrated around riparian areas. According to ADFG management reports, the majority of radio-collared...
