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...

These data were compiled to evaluate the effects of seed coat treatments on the emergence and growth of four native Intermountain West perennial grasses exposed to six different water availability regimes. The objective of our study was to evaluate how seed coat treatments influence seed response and seedling performance for different species exposed to different regimes of water...

These data were compiled to document changes to plant community composition following large-scale energy development. The objective of our study was to evaluate plant diversity responses to energy development at multiple scales, and to compare plant diversity within solar panel microsites. These data were collected between 2023 and 2024 in the Mojave Desert, approximately 50 km northeast...

These data were compiled to highlight hybridization mosaics and genotype-environment associations across three study systems containing taxa critical to widespread plant communities in western North America: Artemisia tridentata, Ericameria nauseosa, and Sphaeralcea fendleri. Objective(s) of our study were to: (1) use genomic data to identify divergent evolutionary lineages (hereafter...

These data were compiled to support ecosystem monitoring and management and to inform ecological transition probabilities and drivers. Objective(s) of our study were to produce maps of ecological states each year during 1986-2022 within two dominant ecological site groups (ESGs) in our study area. These data represent annual time series digital maps of ecological states in the Semiarid...

These data were compiled for the creation of a continuous, high-resolution transboundary land cover map of the Sonoran and Mojave Desert ecoregion within Bird Conservation Region 33 (BCR 33). Objective(s) of our study were to, 1) develop a machine learning algorithm trained to classify vegetation land cover using remote sensing spectral data and phenology metrics from 2013-2021, over the...

These data were compiled for a literature review exploring science that informs plant material sourcing and selection in the interior central and western United States. Objectives of our study were to compile and summarize scientific literature that informs plant material selection to synthesize the state of knowledge relevant to decision-making. These data represent scientific studies...

These data are a surface water classification map of surface water in the riparian corridor of Grand Canyon between Glen Canyon and Pearce Ferry, Arizona, published in ESRI shapefile format. The map was classified from 0.2 m resolution, multispectral imagery (Sankey and others, 2024) and are the same spatial resolution as the imagery. In order to differentiate between the boundary...
