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)

Meteorological Data for Selected Sites along the Colorado River Corridor, Arizona, 2014-2015

These data are records collected from six automated weather stations in operation between January 1, 2014 and December 31, 2015 within the Colorado River Corridor of Grand Canyon National Park and Glen Canyon National Recreation Area. Data collection locations, equipment configurations and methods follow those of the original report (OFR 2014-1247). These files are 4-minute interval dat

Genetic analyses of Astragalus sect. Humillimi data in the southwest USA

These data were compiled to support effective conservation for species within Astragalus sect. Humillimi. Two species, A. cremnophylax var. cremnophylax and A. humillimus are federally listed as endangered taxa. The data provided herein were used to resolve the relationaships among taxa, the population structure within taxa, and genetic diversity within taxa. The data are provided in a STRU...

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 sca

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...

Food Web Data, Colorado River Corridor, Grand Canyon, Arizona, 2006

These data were compiled for a manuscript that examines the riverine food-web structure of the Colorado River below Glen Canyon dam to its confluence with Lake Mead. Tissue from primary producers (vascular plants and algae) and consumers (aquatic invertebrates and fish) were collected before and after monsoon floods in 2006 along the 388 kilometer segment of the Colorado River in the Sout

Climate, hydrology and riparian vegetation composition data, Grand Canyon, Arizona

These data were compiled for monitoring riparian vegetation change along the Colorado River. This file contains data recorded at 42 sandbars between Lees Ferry and Diamond Creek, AZ, which are sampled for both geomorphic and vegetation change annually. Field data contained here were collected from 2012 to 2016 in September and October of each year. Plant species cover values in 5441 1m^2 qu...

Watershed potential erosion rate ranking system and check-dam placement suitability data within the Southern Rockies Landscape Conservation Cooperative (SRLCC)

Using Natural Resource Conservation Service (NRCS) soil databases, topographic features derived from digital elevation models, stream networks, and regional climatic patterns, I developed a ranking system for watershed potential erosion rates and suitability for check-dam placement across the SRLCC. This ranking system serves as a first step for land managers to prioritize areas for c

Geomorphology and Campsite Data, Colorado River, Marble and Grand Canyon, Arizona

This ESRI geodatabase consists of 5 feature datsets with 23 individual polygon feature classes and two raster datasets. A master campsite polygon feature class represents the boundaries of campsites identified in the 1973, 1984, and 1991 campsite inventories of the Colorado River corridor in Grand Canyon, Arizona. The other polygon feature classes represent camp locations along the Colorado...

Landscape-scale wildlife species richness metrics

These raster data represent the results of a case study in Arizona on how vertebrate richness metrics can be used with existing state and federal guidance in wind and solar energy facility siting. Each of the four geodatabases (see Cross References) contain eight native terrestrial wildlife group models in Arizona: 1) all vertebrates, 2) amphibians, 3) reptiles, 4) birds, 5%

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 th
