DATA RELEASE - Riparian vegetation, Colorado River, and climate: Five decades of spatiotemporal dynamics in the Grand Canyon with river regulation—Data

These data include image-based classifications of total vegetation from 1965, 1973, 1984, 1992, 2002, 2004, 2005, and 2009, and characteristics of the river channel along the riparian area of the Colorado River between Glen Canyon Dam and Lake Mead Reservoir.

DATA RELEASE - Laboratory experiment data—turbidity response to increasing silt and clay concentration-Data

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.

DATA RELEASE & MODEL - Humpback Chub and Rainbow Trout Joint Mark-Recapture Data and Model, Colorado River, Arizona-Data & Model

These data were compiled for a joint mark-recapture analysis of humpback chub and rainbow trout and include capture histories for both species, and 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.

DATA RELEASE - Food Web Data, Colorado River Corridor, Grand Canyon, Arizona, 2006-Data

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 & algae) and consumers (aquatic invertebrates & fish) were collected before and after monsoon floods in 2006 along the 388-kilometer segment of the Colorado River in the...

DATA RELEASE - Long-term Experimental Forest Growth and Drought Data

Forests around the world are experiencing severe droughts and elevated competitive intensity due to increased tree density. These data were compiled to represent multi-decadal forest growth across eight different experimental forests in the United States, each with replicated levels of density treatments, as well as an important drought index correlated to growth.

Undiscovered Continuous Gas Colorado Plateau

This dataset is based on U.S. Geological Survey (USGS) resource assessments for “undiscovered” gas 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 focused on the amount of undiscovered continuous gas because...

Vegetation and Soils Data from Grazed and Ungrazed Watersheds in the Badger Wash Study Area, Colorado, USA

In 2004 U.S. Geological Survey biologists recorded vegetation and biological soil crust (BSC) cover by species as well as measured soil stability and compaction data along 85 transects at the Badger Wash study area, approximately 10 miles northwest of Mack in western Colorado. Soil samples were collected and processed for chemistry and texture. Using analysis of variance and nonmetric...

Geomorphic Change-Sediment Transport Data for the Little Colorado River, Arizona, USA

These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include topographic data collected by LIDAR and total station in June 2017, high water marks from nine historic floods, and control points and gage structures. Topographic data include ground topography collected by LIDAR and channel bathymetry collected by total...

Population dynamics of humpback chub, rainbow trout and brown trout in the Colorado River in its Grand Canyon Reach: fit and sim input data

These data were compiled to fit an integrated population model of brown trout in the Glen Canyon Reach of the Colorado River and test different hypotheses regarding the driver of brown trout population dynamics. Also, data were compiled as inputs for a model to simulate population dynamics and species interactions among brown trout, rainbow trout and humpback chub in the Colorado River between...

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 data for...

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 (cultural service...

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 Forecasting Changes...
