Locations of sites at which U.S. Geological Survey (USGS) biologists surveyed for Temblor legless lizards (Anniella alexanderae) from 2022 to 2025 and the results of those surveys. At the time of the species description, little was known about the distribution of the Temblor legless lizard beyond a few localities. Surveys were designed to gather information on the distribution of Temblor...

Soil cores were collected across the marshes of Don Edwards San Francisco Bay National Wildlife Refuge in California to assess belowground properties and for radioisotope dating. Data from the soil cores include dry bulk density, organic matter proportion, carbon, and accretion rates. These data were then used to calibrate a wetland model (WARMER3) to assess future elevation and...

To better inform continued offshore wind energy development in the region, U.S. Geological Survey, Western Ecological Research Center (USGS-WERC) has updated the database of marine bird vulnerabilities to offshore wind energy infrastructure (OWEI) in the Pacific Outer Continental Shelf Region (POCS; waters within the Exclusive Economic Zone off California, Oregon, and Washington). The...

This dataset provides estimates of aboveground forest carbon for all live trees with diameter at breast height at or above 20 centimeters in 151 second-growth forest plots in Redwood National and State Parks. The dataset contains all existing field observations along with projections from the Forest Vegetation Simulator in five year increments from 2024 to 2064.

Joshua trees (Yucca brevifolia, Y. jaegeriana) are iconic, foundational species of the Mojave and Sonoran Deserts in North America. Due to their ecosystem importance, long generation times, and low resilience to disturbance, these hybridizing sister species are increasingly the focus of conservation efforts. Predicting Joshua tree responses to future climate, along with the extent of...

This dataset contains water level, water temperature, and vegetation data from 12 locations within the Nisqually River Delta, Washington from 2010 to 2015. This dataset was part of a larger monitoring effort to document hydrological and vegetation changes throughout the Nisqually River Delta following large scale estuarine restoration (dike removal) in 2009.

A suite of tables filled with greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) survival data and environmental covariate values, extracted to sage-grouse nest, brood, and general locations, as well as lek locations. We quantified 8 indicators of temperature and/or moisture conditions across time spans representing lags of 0-1.5 years, while accounting for other...

Monitoring population connectivity to inform management is especially important in regions at the very edges of wilderness where native fauna and flora face habitat reduction, degradation, and fragmentation. One such region is the Ivanpah valley along the California/Nevada border, where development (i.e., solar facilities, recreational utility vehicle use) continues to encroach on the...

The U.S. Geological Survey, Western Ecological Research Center collected sediment and accretion data at two marshes in San Francisco Bay, California over the course of 15 months, capturing a full hydrological year and two spring-summer transitions. Sediment traps were deployed monthly in triplicate along transects of increasing distance from sediment sources (i.e., channels) to capture...

We collected cattle GPS location data within three sites across the Great Basin ecoregion. We then coupled these data with multi-resolution remotely sensed vegetation, hydrology, and topographic data to develop a cattle resource selection surface across Nevada and northeastern California. This layer can support grazing management through targeted or rotational grazing by providing a...

We compared genetic diversity and body condition indices among two source locations in Catron County, New Mexico (Whitewater Creek and Middle Fork Gila) and the recipient population (Saliz Creek) to evaluate individual- and population-level fitness responses related to the admixture of gene pools following the the translocation of Mogollon Narrow-headed Gartersnakes (Thamnophis...

This dataset provides estimates of the proportion of basal area that survived along with burn severity indices for 585 plots following four large fires in California, including the Carr (2018), Dixie (2021), Caldor (2021), and KNP (2021) fires.
