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...

Scenario for Impacts to Ecosystem Attributes Colorado Plateau

We assessed the spatial pattern and extent of potential impacts of spatially overlapping high intensity land-use and aridification trends on landscape attributes: crop productivity, soil productivity, vegetation and wildlife habitat, and recreation tourism economy, as well as two ecosystem services: water availability (provisioning service) and spiritual and cultural values (cul

Occurrence records and vegetation type data used for species distribution models in the western United States

These data are species distribution information assembled for assessing the impacts of land-use barriers, facilitative interactions with other species, and loss of long-distance animal dispersal on predicted species range patterns for four common species in pinyon-juniper woodlands in the western United States. The layers in the data release are initial distribution records of two kinds: po...

Humpback Chub (Gila cypha) and Rainbow Trout (Oncorhynchus mykiss) Joint Mark-Recapture Data and Model, Colorado River, Arizona

These data were compiled for a joint mark-recapture analysis of humpback chub and rainbow trout and include capture histories for both species, as well as environmental covariates associated with monthly time steps used to measure survival and growth and environmental covariates used to predict capture probability during each sampling trip. This worksheet also include parameter estimates and...

High Intensity Land-use Overlap Colorado Plateau

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

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 dis

Laboratory experiment data—turbidity response to increasing silt and clay concentration

These data were compiled during a laboratory experiment showing the turbidity response to increasing silt and clay concentration. The sediment used for the laboratory experiment was collected in the Grand Canyon study area, from the bank of the Little Colorado River, approximately 1 kilometer upstream from its confluence with the Colorado River. The sediment was passed through a 63 µm...

Acoustic backscatter—Data and Python Code

These data were compiled for investigating the relationship between acoustic backscattering by riverbeds composed of various riverbed substrates (bed sediment), and for developing and testing a probabilistic model for substrate classification based on high-frequency multibeam acoustic backscatter. The model is described in Buscombe et al. (2017). The data consist of various quantities o

BLM Recreation Visitors, 2014, Colorado Plateau

Bureau of Land Management (BLM) field office recreation data for 2014 was downloaded from the Recreation Management Information System (Yuan et al. 1995, Nickels 2003, Leuders 2015). The unit is number of participants in 2014, which was estimated at the scale of an individual BLM Field Office. Leuders, A. 2015.

Sand classifications along the Colorado River in Grand Canyon derived from 2002, 2009, and 2013 high-resolution multispectral airborne imagery

These data are remote sensing image-based classification maps of unvegetated river-derived sand along the Colorado River. One map is based on imagery acquired in May 2013 and is a classification of sand located above the wetted river channel in the imagery which was acquired at the approximate contemporary low-flow river discharge of 8,000 cubic feet per second (227 cubic meters per second)...

Aeolian mass flux, rangeland monitoring site, and unpaved road reach data

These data were compiled for monitoring and analyzing the amount of windblown (aeolian) sediment at 100 cm height near Moab, UT. Big Springs Number Eight (BSNE) field aeolian passive sediment traps are summarized by location and time period in shapefiles. Shapefiles also include attributes used to analyze patterns in the aeolian transport. Three different BSNE shapefiles represent 1)
