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

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 on...

Continuous Detection PIT Array - Data and Models

These data represent a set of capture histories of rainbow trout (Oncorhynchus mykiss or RBT) captured in the Colorado River (CR) and(or) detected on the multiplexer array in the Little Colorado River (LCR). Capture trips to the Colorado River occurred in April 2012, July 2012, September 2012, January 2013, April 2013, July 2013, September 2013, January 2014, Apri

The influence of water temperature on salmonid recruitment and adult size in tailwaters across western North America—Data

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length. First, we linked reservoir storage capacity and dam size to the warmest monthly water temperature per water year (WY) to assess the influence of low storag...

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.

River Valley Sediment Connectivity Data, Colorado River, Grand Canyon

This workbook contains spatial data on the hydrology, sedimentology, and vegetation extent within the Colorado River corridor from 60 to 78 miles (97 to 125 kilometers) downstream from Glen Canyon Dam, Arizona. In combination with the accompanying MATLAB scripts, these data were used to generate the results within the accompanying manuscript (Kasprak et al., Quantifying and Foreca

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...

Grand Canyon Whitewater Boater Data, Convergent Validity between Willingness to Pay Elicitation Methods

These data were complied for the primary analysis underlying the results presented in the manuscript associated with these data (see Larger Work Citation). The data was collected from a 2015 survey of private party Grand Canyon boaters. The open document file contains 3 data sheets: 1) variables used in the Table 2 comparison of samples, 2) the core dichotomous choice contingent valu

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...

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...
