USGS’s Southeast Climate Adaptation Science Center and the University of Tennessee, Knoxville have launched a research effort to support southeastern states and other partners engaged in the process of preparing revisions of State Wildlife Action Plans for 2025. Specifically, this effort focuses on supporting attempts to integrate climate change considerations into SWAPs. Different...

This data release hosts detrital zircon U-Th-Pb geochronology data that were created to support geologic mapping and research in the context of the Geologic Framework of the Intermountain West Project supported by the National Cooperative Geologic Mapping Program. These data characterize the deposition age and provenance of Cretaceous stratigraphic units exposed in the Piceance Creek...

As part of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) efforts in the Delaware River Basin (DRB), a soil moisture sensing testbed was established at USGS Delaware County Observation Well - DE 723 located in a managed meadow setting in Glen Mills, PA. Traditional in situ soil moisture sensors, a remote sensing cosmic ray neutron sensor (CRNS), and...

We used an 18-year dataset (2001 to 2019) incorporating year, sex, hurricane occurrence and sampling effort to estimate survival using Cormack–Jolly–Seber (CJS) models in Program Mark. Annual survivorship estimates were high from 2001-2003 for both sexes (91-96%) and variable from 2006-2014 (77-92%). Beginning in 2015 survival estimates exhibited a steeper decline (females: 65%, males 75...

In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey evaluated geomorphic conditions within Fern Ridge Lake near Eugene, Oregon, to inform cultural resources management and other natural resources decisions. Reservoir erosion and deposition during seasonal flood-control operations have formed a diverse array of landforms that can impact water storage, aquatic...

This dataset describes (a) concentrations of nutrients and related constituents, and (b) discharge in the lower Boise River (Idaho) and its primary tributaries for Water Years 1994 through 2023 and 1969 through 2024, respectively. Constituents include water column concentrations of suspended sediment, total phosphorus, dissolved phosphorus, orthophosphate as phosphorus, total nitrogen...

Data set includes field observed cover of several vegetation functional groups, e.g. annual herbaceous, perennial herbaceous, exotic annual grasses, perennial bunch grasses, shrubs, sagebrush shrubs, non-sagebrush shrubs, bare mineral soil, rocks, and litter. Additionally, if tree canopy was present within field plots, tree canopy cover was estimated, forest type recorded, and the number...

This data release presents multi-year ecosystem metabolism model outputs for Brownlee Reservoir at varying depths across three locations (River Miles 318, 300, and 286) along the Snake River. Data include field-collected model input data and model outputs of daily gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP). Field data were collected from...

We investigated male reproductive success of feral horses (Equus caballus) at Conger and Frisco Herd Management Areas (HMAs) in Utah, USA between 2017 and 2020. We collected data on male social status (harem stallion, lieutenant, tag, bachelor or in natal group) and group type (single male or multi-male) at both sites, and at Conger we additionally examined social interactions among...

Stream temperature data and streamflow data from headwater streams in the upper Snake River basin, Wyoming and upper Yellowstone River basin and Flathead River basin in Montana. These datasets were assembled to assess how stream temperature and streamflow in headwater streams deviates from downstream gages in order to better understand tools to estimate streamflow at a variety of...

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...

In cooperation with the Tennessee Wildlife Resources Agency (TWRA) and University of Tennessee Knoxville (UTK), the U.S. Geological survey (USGS) collected cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and water-quality field data at 4 sites on the Clinch River from November 2020 to December 2023. The goal for the sample data was to...
