Data
Our interdisciplinary, integrated science teams develop various data sets in support of the USGS mission areas. This information then aids natural resource managers in decision making and support of the complex issues they face in today's world. The data and tools listed here are official USGS data releases.

Soil-climate estimates in the western United States: climate averages (1981-2010) Soil-climate estimates in the western United States: climate averages (1981-2010)
We provide a collection of data reflecting estimates of soil-climate properties (moisture, temperature, and regimes) based on climate normals (1981-2010). Specifically, we provide estimates for soil moisture (monthly, seasonal, and annual), trends of spring and growing season soil moisture (Theil-Sen estimates), soil temperature and moisture regimes (STMRs; discrete classes defined by...
spatial_nsm: Spatial estimates of soil-climate properties using a modified Newhall simulation model spatial_nsm: Spatial estimates of soil-climate properties using a modified Newhall simulation model
We developed a software framework to estimate high-resolution spatiotemporal soil moisture (monthly, annual, and seasonal) and temperature-moisture regimes. Our approach builds on the Newhall simulation model, allowing for the substitution of data and parameters, such as climate, snowmelt, soil properties, alternative potential evapotranspiration equations, and air-soil temperature...
Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021 Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021
We collected fleas from colonies of black-tailed prairie dogs in Badlands National Park, South Dakota, 2020-2021. Specifically, we tested fipronil grain for flea control on two colonies: Colony A in 2020 and Colony B in 2021. To assess on-host flea numbers (in 2020 and 2021), we anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We...
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.1.0 grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.1.0
Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most...
GPS locations of feral horses in Utah, USA, from 2016-2020 GPS locations of feral horses in Utah, USA, from 2016-2020
Data represent locations of mares and stallions in Utah. Data were collected using GPS radio collars on mares or tail transmitters braided into the tails of stallions, at a 2-hour fix rate for a period spanning 2016 to 2020. Horses were located at Conger Herd Management Area (HMA) or Frisco HMA in the Great Basin ecosystem of Utah, USA.
Online survey responses from users of the Joint Fire Science Program Fire Science Exchange Network from February 2021 Online survey responses from users of the Joint Fire Science Program Fire Science Exchange Network from February 2021
The USGS, on behalf of the Joint Fire Science Program (JFSP), conducted an evaluation of the Fire Science Exchange Network (FSEN), which connects wildland fire scientists and practitioners through 15 individual exchanges across the United States to help address complex wildfire needs and challenges. This data set is from an online survey sent to more than 16,000 exchange network users...
Data on black-tailed prairie dog body condition, annual and monthly survival, and reproduction on sites treated or not treated with 0.005% fipronil grain for flea control and plague mitigation in South Dakota, USA, 2017-2020 Data on black-tailed prairie dog body condition, annual and monthly survival, and reproduction on sites treated or not treated with 0.005% fipronil grain for flea control and plague mitigation in South Dakota, USA, 2017-2020
We live-trapped and sampled black-tailed prairie dogs in Badlands National Park and Buffalo Gap National Grassland, South Dakota, 2017-2020. Sampling occurred on sites treated with 0.005% fipronil grain for flea control and plague mitigation, and non-treated sites functioning as experimental baselines. Prairie dogs were trapped, sexed, aged (adult or juvenile by size), weighed to the...
Effects of deltamethrin applications on non-target small mammal populations in South Dakota, Colorado, and Idaho, 2010-2017 Effects of deltamethrin applications on non-target small mammal populations in South Dakota, Colorado, and Idaho, 2010-2017
We trapped small mammals at two sites in Badlands National Park, Pennington County, South Dakota from 2013-2017; two sites in Larimer County, Colorado from 2010-2011; and four sites in Adams County, Idaho from 2014-2017. Each site contained at least one or more treated plots (deltamethrin dust applied to burrows or bait stations for flea control) paired with one or more non-treated plots...
Detections of burros from helicopter aerial surveys in the southwestern US, 2016-2018 Detections of burros from helicopter aerial surveys in the southwestern US, 2016-2018
Feral burros (Equus asinus) and horses (E. ferus caballus) inhabiting public land in the western United States are intended to be managed at population levels established to promote a thriving, natural ecological balance. Like many large ungulate populations, management agencies employ aerial surveys to obtain estimates of horse and burro population sizes. Double-observer sightability...
Occurrence of plants in plots along the Gunnison River, Colorado, 1990-2017 Occurrence of plants in plots along the Gunnison River, Colorado, 1990-2017
In 1990 the US Geological Survey Fort Collins Science Center and National Park Service Water Resources Division established 133 permanent 1meter (m) X 2 m plots along the Gunnison River near Warner Point in Black Canyon of the Gunnison National Park. A one-dimensional hydraulic model was calibrated to determine the inundation necessary to inundate each plot, and this can be combined with...
Data on deer mouse and vole plague vaccination and captures in central New Mexico, 2019-2021 Data on deer mouse and vole plague vaccination and captures in central New Mexico, 2019-2021
Our study was conducted from 2019-2021 in Lincoln National Forest, New Mexico. We live trapped deer mice and two species of voles in Sherman traps, mostly at nighttime, from June-October 2019 and June-September 2020-2021. We marked each rodent with ear tags and a passive integrated transponder for permanent identification. We used an F1 antigen vaccine to vaccinate some individuals...
lcp_centrality: Defining least-cost paths and graph theory centrality measures lcp_centrality: Defining least-cost paths and graph theory centrality measures
We present software that creates least-cost path spanning trees, a least-cost path minimum spanning tree, and graph theory centrality measures. The software was developed to support identification of population structures--specifically, greater sage-grouse (Centrocercus urophasianus), but also support other species or graph theory applications where least-cost paths are desired. We used...
