Data

These spatial and tabular data were compiled to have a decade-long record of the water usage in the riparian corridor and the wetlands near Phoenix, Arizona called the Tres Rios area to observe the effect of riparian and wetland health as characterized by vegetation greenness and its water use or evapotranspiration. The objective of our study was to quantify evapotranspiration (in...

During steady releases from Glen Canyon Dam in 2021, geomorphic data were collected for the Colorado River in Grand Canyon National Park from Lees Ferry to Pearce Ferry. A boat based survey collected position data using Global Navigation Satellite Systems and bathymetry data using a multibeam sonar system. Individual water's edge locations were measured using total stations referenced to...

This dataset describes the catch of humpback chub (Gila cypha) in baited hoop nets from humpback chub aggregations monitoring trips that occurred 2010-2024. Additionally, this data set includes tables that describe the number of captures and recaptures for repeat visits (i.e., mark-recapture) as well as categorical habitat scores from two experts assigned to the Colorado River in western...

These data were compiled for upland vegetation and soil condition assessment and monitoring in arid, semiarid, and montane areas of northwest San Juan County, Utah, USA, near The Nature Conservancy's Canyonlands Research Center (CRC) at Dugout Ranch. The sampling area includes the Needles District of Canyonlands National Park, the Indian Creek Allotment of the Bureau of Land Management...

These data were compiled to support a synthesis of over two decades of riparian plant and ecosystem water use estimates from the drylands of North America. The objectives of the study were to determine if some riparian plant communities exhibit lower plant water use than others, assess if plant water use changes under hotter climates, and evaluate if models based on existing data, plant

These data were compiled to evaluate the impacts of large-scale solar energy development on wind-borne dust production. Objectives of the study were to evaluate dust produced during construction and operation of solar energy facilities constructed using varying construction methods. We also collected data on plant and soil variables that are known to be important predictors of dust...

Bathymetric, topographic, and grain-size data were collected in May 2014 along a 27 mile (43.5 kilometer) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 61.1, about 0.6 miles (1 kilometer) above the confluence of the Colorado and Little Colorado Rivers and ends at river mile 88.1 at the upstream boundary of the Bright Angel Rapid...

This shapefile depicts individual campsites areas surveyed at 37 sandbar sites along the Colorado River through Grand Canyon, from Lees Ferry to Diamond Creek, from 1999 to 2024. Campsite areas were measured through total station surveys, outlining the perimeter of areas available for camping use at each study site. Campsite area is defined as an area with smooth substrate, typically...

These data were compiled to provide necessary inputs to run the models in our paper, Operating Lake Powell Under Uncertainty: Strategies for Sustainable Sand Management in the Colorado River. Objective(s) of our study were to identify dam release strategies for improved management of sand resources in Grand Canyon. These data represent model inputs. Hydrology inputs were derived from U.S...

These data were compiled to measure the stand structure, including age class distribution, of Joshua tree (Yucca brevifolia and Y. jaegeriana) as measured on 61 1000 m2 plots.The objective of our study was to provide the U.S. Fish and Wildlife Service with demographic data, particularly on recruitment, of the Joshua trees for their use in decisions that the Service makes for the...

Many non-native invasive grass species increase wildfire activity and recover more quickly than native species. This invasive grass-fire cycle has severe negative consequences for ecosystems, creating a need to understand how different invasive grass species alter fuel characteristics and fire behavior, as well as effective treatments to reduce their spread. We reviewed and compiled...

These data were compiled for monitoring riparian zone trends and changes in the Navajo Nation as part of a study to document riparian ecosystem health and its water use in support of potential restoration efforts. The objective of our study was to monitor the short and medium-term effects on the riparian vegetation in relation to evapotranspiration changes, drought, and other...
