Climate, Wildfire, and Erosion Data, Western US

These data were used to examine how post-fire sedimentation might change in western USA watersheds with future fire from the decade of 2001-10 through 2041-50. The data include previously published projections (Hawbaker and Zhu, 2012a, b) of areas burned by future wildfires for several climate change scenarios and general circulation models (GCMs) that we summarized for 471 watersheds

USGS 2017 AKasprak Geomorphic Process Topographic Form—Data

These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys." These data include (1) raster digital surface models (DSMs) from 2002, 2009, and 2013 of seven

Desert Tortoise Ecology and Precipitation, Mojave and Sonoran Deserts—Data

These estimated precipitation data were compiled using the WestMap web site (http://www.cefa.dri.edu/Westmap/). We selected pixels on the map shown on their web site that were in the core of our study areas: one near Palm Springs, California and the other at Sugarloaf Mountain in the Tonto National Forest of Arizona. WestMap uses PRISM data to...

Grand Canyon Whitewater Boater Data, Temporal Stability of Willingness to Pay Values

These data were complied for the primary analysis underlying the resuts presented in Neher et al., Testing the Limits of Temporal Stability: Willingness to Pay Values Among Grand Canyon Whitewater Boaters across Decades. The data is a combination of data collected for a 1985 survey of private party Grand Canyon boaters, and a 2015 replication survey for that same recreational user group.

Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7—Data

Studies utilizing Global Positioning System (GPS) telemetry rarely result in 100% fix success rates (FSR). Many assessments of wildlife resource use do not account for missing data, either assuming data loss is random or because a lack of practical treatment for systematic data loss. Several studies have explored how the environment, technological features, and animal behavior i

Automated Reference Toolset (ART)—Data

These environmental raster covariate, geospatial vector data, and tabular data were compiled as input data for the Automated Reference Toolset (ART) algorithm.

Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data

These data area classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The water classification data have the same 0.2-meter ground resolution as the imagery....

Southwest Exotic Mapping Program (SWEMP) Database, 2007

The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort between the United States Geological Survey and federal, tribal, state, county and non-governmental organization (NGO) partners in the southwest. This project is an ongoing effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern United States. The d

Riparian Vegetation and Environmental Variables, Colorado River, 2014—Data

These data consist of species relative cover, percent cover of dead plant material, percent cover of soil and rock, and a variety of broad - and local- scale environmental variables. These data relate to sample sites along the Colorado River through Grand Canyon between Lees Ferry and river mile 245. The plant and ground cover data included here were originally collected as a part of annual...

Plant functional traits, Colorado River, Grand Canyon, 2012-2014—Data

These data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data was collected forspecific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon/nitrogen ratio. Seed mass a

Bioelectrical impedance analysis for an endangered desert fish—Data

These data were used to examine the effectiveness of a non-lethal tool (Bioelectrical Impedance Analysis, "BIA") to estimate the physiological condition of endangered and threatened fishes in the Colorado River Basin. We conducted laboratory trials using hatchery-raised Humpback Chub and Bonytail and wild-captured Roundtail Chub, where fish were subjected to different feeding trials t
