Surveyed coordinates and elevations in a 2019 survey of new and previously established cross sections on the Green River in Browns Park, Colorado and Utah Surveyed coordinates and elevations in a 2019 survey of new and previously established cross sections on the Green River in Browns Park, Colorado and Utah
These data were compiled for the National Park Service. Objective(s) of our study were to resurvey previously established cross sections on the Green River in Browns Park, Colorado and Utah, to document changes in channel width, depth, and cross-sectional area. In addition, new cross sections were established in areas that lacked previously surveyed cross sections. These data represent...
Modeled preservation risk to paleontological and cultural resources within Lake Powell and Lake Mead in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled preservation risk to paleontological and cultural resources within Lake Powell and Lake Mead in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). Specifically, these data present modeled risks to paleontological and cultural resource preservation based on projected reservoir water level fluctuations between December 2026 and December 2060 within Lake Powell and...
Repeat photo interpretation of vegetation change from 1910 to 2016 on the Colorado Plateau, USA and contextual data on land use, climate, topography, and geomorphology Repeat photo interpretation of vegetation change from 1910 to 2016 on the Colorado Plateau, USA and contextual data on land use, climate, topography, and geomorphology
These data document over a century of plant community change on the Colorado Plateau (CP) using repeat photography (1910-2016). Photos were taken across a 3100 square kilometer area on the CP largely in areas administered by the NPS and Bureau of Land Management (BLM), including (but not limited to) areas now within Arches National Park and Canyonlands National Park; Glen Canyon National
Species-specific results from RestoreNet seeding and outplanting trials in Southwest, USA drylands, 2018-2022 Species-specific results from RestoreNet seeding and outplanting trials in Southwest, USA drylands, 2018-2022
These data were compiled to assess species performance for 59 native grass, forb, and shrub species that were seeded and (or) planted across 20 RestoreNet sites in the Southwest US. Objectives of our study were to assess species performance within and across ecoregions, across revegetation methods (seeding or outplanting greenhouse-grown seedlings), and by growth form (grass, forb, or...
Modeled subaerial shoreline area and potential dust emissions within Lake Mead and Lake Powell Modeled subaerial shoreline area and potential dust emissions within Lake Mead and Lake Powell
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were used to illustrate how six operational strategies (one baseline and 5 alternatives) could affect subaerial shoreline exposure and potential dust emissions at the Lake Powell and Lake Mead reservoirs. The...
Modeled economic value of angling and whitewater recreation on the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled economic value of angling and whitewater recreation on the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were compiled to predict economic impacts to angling in Glen Canyon and whitewater rafting in Grand Canyon. The objective of our study was to estimate recreation impacts, or changes in consumer surplus, under...
Modeled subaerially exposed river sand available for aeolian transport along the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled subaerially exposed river sand available for aeolian transport along the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). These data were used to illustrate how six operational strategies (one baseline and 5 alternatives) for Glen Canyon Dam could affect sand exposure for aeolian landscape and cultural site resources within Grand Canyon...
Vegetation and soil moisture data from 2019 selective mortality experiment in perennial grassland on the Colorado Plateau, Utah, USA Vegetation and soil moisture data from 2019 selective mortality experiment in perennial grassland on the Colorado Plateau, Utah, USA
These data were compiled to investigate competitive interactions between Pleurphis jamesii and other herbaceous plants in a semiarid grassland community. The objectives of our study were to determine whether selective mortality of either C3 or C4 herbaceous plants led to changes in (1) soil moisture during the growing season, (2) water use by Pleuraphis jamesii during the growing season...
Vegetation composition, soil characteristics, horizontal mass flux, and weather data (2018-2024) from a dryland reclamation experiment at a former uranium mine in northern Arizona, USA Vegetation composition, soil characteristics, horizontal mass flux, and weather data (2018-2024) from a dryland reclamation experiment at a former uranium mine in northern Arizona, USA
These data were compiled as part of an experimental study investigating alternative methods to dryland reclamation. The objective of our study was to evaluate the effects of conventional vs alternative approaches alone and in combination that included different seeding methods, seed mixes, and biological soil crust (biocrust) inoculation. These data were collected within the footprint of...
Remotely sensed observations using Landsat time-series from 2013-2023 to determine water savings for riparian corridor sites in the Lower Colorado River Basin affected by tamarisk defoliation Remotely sensed observations using Landsat time-series from 2013-2023 to determine water savings for riparian corridor sites in the Lower Colorado River Basin affected by tamarisk defoliation
These spatial and tabular data were compiled to have a decades-long record of the water usage in the riparian corridor for 27 selected sites where tamarisk (Tamarix spp) or saltcedar defoliation was reported by ground observations and/or exhibited in Google Imagery at locations across the Lower Colorado River Basin. Data for these sites was measured remotely for plant health as...
State and Transition Classifications for Ecological Sites in the Upper Colorado River Basin, USA State and Transition Classifications for Ecological Sites in the Upper Colorado River Basin, USA
These data were compiled to support systematic analysis of ecological state and transition dynamics at the landscape scale in the Upper Colorado River Basin using published Natural Resources Conservation Service (NRCS) Ecological Site Descriptions (ESDs). Ecological sites are soil and climate-based classes of land that differ in potential plant communities and responses to disturbance...
Mark-recapture and environmental data used to predict humpback chub (Gila cypha) growth rates within the Colorado River in the Grand Canyon from April 2012 to October 2022 Mark-recapture and environmental data used to predict humpback chub (Gila cypha) growth rates within the Colorado River in the Grand Canyon from April 2012 to October 2022
These are the data used for growth modeling in the paper ‘Growth of a threatened desert fish becomes resource dependent when released from temperature limitation in a regulated river’. Growth of ectotherms is strongly tied to temperature but can vary with other factors, especially food acquisition rates. River regulation is widespread globally and often significantly alters both...
