Undiscovered Natural Gas Liquids Colorado Plateau

This dataset is based on U.S. Geological Survey (USGS) resource assessments for “undiscovered” natural gas liquid resources, which are resources that have not yet been extensively proven by drilling (USGS 2014). Individual resource assessments describe the amount of petroleum resources in units with similar geologic features. We quantified the density of natural gas liquid...

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Mojave Vegetation Polygons

The Central Mojave Vegetation Polygons shapefile represents areas of the Mojave Desert classified into vegetation classes or alliances representative of the area from 1997-1999. The classification of these areas were derived from context gathered in the field data, repeat photographs and additional satellite imagery that is not included in this data release. The original map coverage was...

Early Season Invasives Mapping 2001 - 2010, Washington County, Utah, USA

Invasive annual plants such as red brome (Bromus rubens), cheatgrass (B. tectorum), and African mustard (Malcomia africana) can have profound impacts on dryland ecosystems. Potential impacts include the alteration of fuel loads and fire regimes, as well as the competitive displacement of native plant populations. Both of these impacts can significantly degrade habitat quality for wildlife and...

Potential Land-use Intensity, Aridification Trends, Overlap, and Impact Scenarios, Geospatial Data, Colorado Plateau, USA

These geospatial data characterize the potential for geographic overlap among land-use practices and between land-use and climate change on the Colorado Plateau—a dryland region experiencing rapid changes in land-use and facing aridification. They were used to characterize spatial patterns and temporal trends in aridification, land-use, and recreation at the county and 10-km2 grid...

Wind Power Potential 2010 Colorado Plateau

Areas with high potential for utility-grade wind power were based on wind energy adjusted to 80 m and excluding protected areas and land-cover types unsuitable for wind installations (Elliot et. al. 1986, NREL 2010). Data were originally in classes, 3-7, but were assigned 1/0 values for this dataset, and then averaged to create a 10 km2 grid. See citations for details on raw data. Elliot, D....

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Plots Points and Repeat Photographs

The Mojave Plots Points data are 1,219 plot locations in the Central Mojave Desert where field data were recorded and repeat photographs were taken from 1997-1999 to provide context for the classification of the Central Mojave Desert into various vegetation classes. The 1,219 plot locations in the plots points shapefile (plots_points.shp) are each assigned a unique identifier called the...

County Population 2100 Baseline Scenario Colorado Plateau

Future county population was based on projections for 2100 from the Spatially Explicit Regional Growth Model (SERGoM; Theobald 2005). SERGoM simulates population based on existing patterns of growth by census block, groundwater well and road density, and transportation distance to urban areas, while constraining the pattern of development to areas outside of protected areas and urban areas (...

Dataset for plant production responses to climate across water-limited regions

This dataset was constructed from readily available open source climate and vegetation data, like Landsat. This dataset represents the vegetation and climate conditions for a large number of points across the major deserts of the SW USA. The dataset was constructed in order to use the climate pivot point approach (Munson et al. 2013) at the landscape level. Originally this dataset was much...

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999

The U.S. Geological Survey (USGS) Data at Risk (DaR) team partnered with the USGS Southwest Biological Science Center (SBSC) to preserve and release tabular data, shapefiles and field photographs of the Central Mojave Desert from 1997-1999. The data were originally collected as part of an effort through the Desert Managers Group (DMG) to develop scientific information on the distribution and...

Remote sensing derived maps of tamarisk (2009) and beetle impacts (2013) along 412 km of the Colorado River in the Grand Canyon, Arizona

These data are aerial image-derived, classification maps of tamarisk (Tamarisk spp.) in the riparian zone of the Colorado River from Glen Canyon Dam to Separation Canyon, a total river distance of 412 km. The classification maps are published in GIS vector format. Two maps are published: 1) a classification of tamarisk from a 0.2 m resolution multispectral image dataset acquired in May 2009 (...

Low Intensity Land-use Overlap Colorado Plateau

This dataset represents the spatial overlap in areas with present (cropland, grazing, and recreation), potential (petroleum resources), or future (population) low-intensity land-use. The final areas designated as low-intensity land-use represent low intensity relative to the range of values for that variable in this region, either present or future, and do not represent the rate of change,...

Environmental conditions, covariate data used in model fitting, and long-term establishment predictions from 1979 to 2016 in the Great Basin, USA

Data was collected to characterize the conditions under which sagebrush occurs after seeding and wildfire in the Great Basin, and used to parameterize models used to explore adaptive seeding approaches. Data includes plot level field data on sagebrush occurrence, density, weather, and soil moisture conditions in the year that seeding after wildfire occurred. Weather data includes both average...
