5th Code HUC reporting units for the Colorado Plateau Ecoregion Used as analytical reporting units for aquatic conservation elements.
This dataset presents current and future change agent models and combined future potential for change (PFC) within the montane and subalpine conifer forest Conservation Element.The montane and subalpine conifer forest extent was determined by querying the LANDFIRE existing vegetation dataset for montane and subalpine confer forest and clipping the data to the ecoregion boundary.This dataset presents current and future change agent models and combined future potential for change (PFC). Potential for change (PFC) was determined by calculating the maximum potential for change among all change agents within each 1 km reporting unit. Current and future landscape intactness (LCM_C_FZ and LCM_N_FZ) are based on measures...
Although future roads are included in the long-term LCM, we conducted separate spatial analyses intersecting the future layers with our fish distributions to identify the projects or watersheds with the potential to impact fish species of conservation concern. Four datasets were used to represent future road construction in the study area: preferred routes to Nome, Umiat, and Ambler; and proposed forestry roads. These roads were intersected with the distributions of Dolly Varden. The anadromous Dolly Varden habitat distribution and modeled resident Dolly Varden habitat distribution for the 2060s were combined into a single distribution for this analysis. Road intersections were highest for Dolly Varden because Dolly...
This dataset contains RegCM3 Climate Change modeled annual temperature (degrees C) data for the Middle Rockies Ecoregion. This dataset represents the change in July/August temperature between the current and future climate scenarios (1980-1999 and 2050-2069).
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map. The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages. The WBD represents drainage basins as enclosed areas in eight different size categories. Both datasets represent the real world at a nominal scale of 1:24,000-scale, which means that one inch of The National Map data equals 2,000 feet on the ground. To maintain mapping clarity not all water features are represented and those that are use a moderate level of detail. The NHD and WBD are digital vector datasets used by geographic information systems (GIS)....
Runoff simulated by the biogeography model MAPSS using RegCM3 climate with GENMOM projections as boundary conditions. Units are millimeters of water. MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid (http://www.databasin.org/climate-center/features/mapss-model). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation) as well as soils information (texture, depth). Based on a set of climatic thresholds, the model...
This data set is comprised of categorical values assigned based on size of contiguous habitat blocks of WAFWA Elk distribution in forested areas within the Middle Rockies Ecoregion.
Average Annual Temperature (2015-2030) simulated by RegCM3 with ECHAM5 projections as boundary conditions. Units are degrees Celsius. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections. The data were downscaled statistically by calculating differences (anomalies) between the RegCM3 results with GCM-driven boundary conditions for 1968-99 and those for a future period, in this case 2015-2030. The anomalies were added (temperatures) or multiplied (precipitation) to a climate baseline from PRISM (Parameter-elevation Regressions on Indepenent Slopes Model - prism.oregonstate.edu) data based on historical observations. The PRISM baseline was calculated...
This dataset contains TIGER roads, electrical transmission lines, Integrated Climate and Land Use Scenarios (ICLUS), wind turbine, and oil and gas wells, Data was reclassified and merged together to create a an anthropogenic layer.
This dataset shows the current distribution of Inter-Mountain Basins Montane Sagebush Steppe (LANDFIRE EVT) within the context of current and near-term terrestrial intactness and long-term potential for energy development and potential for climate change (4KM reporting units). Current terrestrial intactness is based on current measures of landscape development, fire regime and vegetation impacts, and fragmentation. Near-term intactness includes estimates of urban growth and expansion of invasive vegetation. Long-term potential for energy development is based on areas of potential for wind, solar, and petroleum development derived from multiple sources. Long-term potential for climate change is based on absolute...
This dataset presents the current potential distribution of lowland leopard frog in the context of current and near-term aquatic intactness, and long-term potential for climate change at the watershed (HUC5) scale. Current aquatic intactness is based on current measures of landscape development, water quality, hydrologic impacts, and road impacts. Near-term intactness includes estimates of urban growth. Long-term potential for climate change is based on absolute changes in runoff, precipitation, temperature, and vegetation change estimated using climate projections (RegCM3 regional climate model based on ECHAM5 boundary conditions) and a biogeography model (MAPSS) for the period 2045-2060. The aquatic intactness...
This dataset shows historic change agents and disturbance types within the historic distribution of this vegetation community as mapped in the LANDFIRE Biophysical Settings (BpS v1.0) dataset. The BpS provides an estimate of the distribution of this community under pre- Euroamerican settlement reference conditions (including historic fire regimes). While based on biophysical gradients and limited training plot data, with resultant inaccuracies of prediction, the BpS provides the best available estimate of the distribution of this vegetation community. Existing vegetation classifications are inadequate for estimating the distribution of this community for the purposes of this analysis, because they only provide a...

This database contains GIS datasets representing the distribution of mule deer habitat throughout the United States and Canada (Alberta and Saskatewan only). Mule deer habitat is divided into 6 separate GIS layers corresponding to 6 types of mule deer habitat: 1)limited range, 2) summer range, 3) other important habitat, 4) winter range, 5) winter concentration, and 6) year-round population. Information on mule deer limiting factors associated with each habitat type is provided within the GIS datasets. Habitat delineations were identified through a Delphi process on a state-by-state basis and were subsequently tablet-digitized from 1:250,000 scale maps.
We compared current 5th level watersheds with Russian olive using LANDFIRE with the probability of areas having suitable habitat for Russian olive in 3 future periods based on climate modeling. Note that LANDFIRE data did not distinguish between Russian olive and tamarisk.
Aerial Insect and Disease Detection Survey(ADS) for insect and disease activity in 2003. The ADS data was obtained to be used for BLMs REA Process for the Middle Rockies ecoregion. The original data was combined from USFS regions within the ecoregion then clipped to the Middle Rockies Level III ecoregion plus a buffer that consists of the 5th level Hydrologic Unit Code (HUC) watersheds that intersect the ecoregion.
The LANDFIRE existing vegetation layers describe the following elements of existing vegetation for each LANDFIRE mapping zone: existing vegetation type, existing vegetation canopy cover, and existing vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery, biophysical gradient layers, and classification and regression trees. DATA SUMMARY: The existing vegetation height (EVH) data layer is an important input to LANDFIRE modeling efforts. Canopy height is generated separately for tree, shrub and herbaceous cover life forms using training data and a series of geospatial data layers. EVH is determined by the average height weighted by species...
Caribou typically undergo seasonal migrations between summer calving grounds, mosquito-relief areas and winter foraging sites, with migration distances varying amongst herds. In the CYR study area, the larger, arctic herds, undergo seasonal migrations of distances up to 640 km, with annual movements of some caribou totaling more than 5000 km; while the smaller, more regional herds farther south, tend to undergo much shorter seasonal movements. Wider ranging herds include the Western Arctic, Central Arctic and Porcupine herds. The more localized herds include the Fortymile, Galena, Hodzana Hills, Macomb, Ray Mountains, White Mountains and Wolf Mountain herds. The Western Arctic herd has the largest range and most...
Natural Heritage New Mexico used standard photo-interpretive techniques to survey 1,654 digital orthophoto quarter quads (DOQQs) for ground disturbance caused by GPD. The surveyed area covered 7,944,262 ha. To assess accuracy, field observers walked 101, 2 km transects on the Navajo Nation and 50 on the Hopi Reservation, distances of approximately 202 and 100 km, respectively. On the surveyed DOQQs we delineated 40,587 ha of apparent GPD disturbance. We found apparent GPD disturbance that, when confirmed on the ground, will extend the GPD range up to 50 km to the northwest.
ESRI file geodatabase of greater sage-grouse (Centrocercus urophasianus) range-wide breeding densities at 25% (BreedingDensity25), 50% (BreedingDensity50), 75% (BreedingDensity75) and 100% and the the current and historic distribution of potential habitat, or range, of the Greater Sage-grouse in Western North America were merged together. The current and historic distriubtion of potential habitat was initially researched and compiled by Dr. Michael A. Schroeder, research biologist for the Washington State Department of Fish and Wildlife. The initial draft of current and historic range data was mapped and submitted to state, federal, or provincial natural resource agencies and other experts for review, comment, and...
