Data

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.

This data file contains observations recorded during field surveys of post-fire vegetation in the 2021 Caldor and 2022 Mosquito Fires in the Sierra Nevada of California. The surveys were performed in summer 2023. All tree species were surveyed and treated the same.

The monitoring program at San Nicolas Island (SNI) was conceived in anticipation of the potential reintroduction of southern sea otters to the island. Subtidal monitoring was initiated in autumn of 1980 at six sampling sites positioned around the island to sample communities exposed to a range of wave exposures and other oceanographic conditions. Three additional sites were subsequently...

Surface elevation table and marker horizon (SET-MH) plots were installed at multiple marshes along the Pacific coast beginning in 2012. They are used to measure millimeters of change in marsh elevation and accretion over time. This dataset includes SET pin height to measure elevation change and associated feldspar marker horizon depth to measure surface accretion spanning the Pacific...

We delineated the existing empirical and modeled ranges of western and eastern Joshua trees (Yucca brevifolia and Y. jaegeriana, respectively) with high fidelity and across their ranges in Arizona, California, Nevada, and Utah, USA. Most species distribution models (SDMs) rely on sparse species occurrence datasets and random pseudoabsences. In contrast, the tall stature and distinctive...

The data consist of counts of sea otters in each year from 1980 to 2017 that are within 2 kilometers of the location of the 6 original subtidal ecosystem monitoring sites around San Nicolas Island, California. Beginning with the reintroduction of sea otter to the waters of San Nicolas Island in 1987, three to four surveys have been conducted at the island each year. Shore-based observers...
