Data

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...

These data were compiled to show where significant river-sourced aeolian sediment deposits are present along the Colorado River downstream of Glen Canyon Dam in the Grand Canyon from Lee’s Ferry to the Diamond Creek confluence located 225 miles downstream. These deposits represent 118 active aeolian dunefields and were created by the Grand Canyon Monitoring & Research Center using field...

These data were compiled to provide land-management relevant information on the native and nonnative subspecies (subsp.) of Phragmites australis (subsp. americanus and subsp. australis, respectively) in Glen Canyon National Recreation Area (NRA), Grand Canyon National Park (NP), Arches National Park, and Bill Williams National Wildlife Refuge. Specifically, the goals of this work were to...

These data were compiled to determine the rate and magnitude of channel-planform change, and the topographic change of the channel and floodplain in Echo, Island, and Rainbow Parks within Dinosaur National Monument between the 1990s and 2019. The objective(s) of our study were to analyze geomorphic change within Echo, Island, and Rainbow Parks to determine the magnitude and style of...
