Data
Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

Sagebrush recovery projections across the biome, 30 years after two seeding treatment applications, and associated model data (1986-2021)
This data release contains a formatted dataset compiled from multiple databases on restoration treatments and environmental conditions from across the sagebrush (Artemisia spp.) biome. With these data, we modeled the influence of environmental conditions and restoration treatments on trends in sagebrush cover using generalized additive models. We then used these models to create maps of projected
Phenology observations for cheatgrass (Bromus tectorum) and red brome (Bromus rubens) in the western United States
This dataset consists of phenology observations of red brome (Bromus rubens) and cheatgrass (Bromus tectorum) collected at long-term monitoring sites and using daily timelapse camera imagery in the western United States. These observations include the location and day of year that flowering or senescence was observed per species. For timelapse camera images, 'flowering' observations denote the dat
Projections of post-fire cover of non-native short-lived grasses and forbs under current and future climate conditions
These data provide current and future projected post-fire invasion risk by non-native short-lived grasses and forbs based on vegetation cover data from 26,729 plots in the western United States that burned prior to being sampled. Projected post-fire invasion risk was calculated using random forests with gridded climate, soil, and topographic predictor variables following Prevéy et al. (2024). Proj
Whole rock geochemistry for the Central Death Valley volcanic field, California
This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data for Neogene rocks in the Central Death Valley volcanic field (CDVVF), California. Samples from the CDVVF were collected in order to constrain the temporal and compositional magmatic evolution of the area.
High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, Utah from 2021-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et. al. 2021) using Agis
Climate-Growth Analysis for Updated and Existing Tree-ring Network near Columbine Lake, Grand County, Colorado
This data release is tree-ring data near Columbine Lake and surrounding region, Grand County, Colorado (Latitude 40.27˚ N, Longitude -105.83˚ E NAD83). Re-collection of four existing tree-ring sites (Hot Sulphur Springs Psuedotsuga menziessii (HSU), Lexan Creek Picea engelmannii (LCU), Monarch Lake Pinus ponderosa (MLU), and Vasquez Mountain Psuedotsuga menziessii (VMU)) was conducted to update da
Maps of habitat suitability improvement potential for the Gunnison Sage-grouse (Centrocercus minimus) satellite populations in Southwestern Colorado
Habitat restoration efforts to conserve wildlife species are often conducted along a range of local site conditions, with limited information available to gauge relative outcomes for habitat suitability among sites and identify those that may lead to the greatest returns on restoration investment. We leveraged existing resource selection function models to generate heatmaps of spatially varying ha
Spectral reflectance measurements of standard reference materials in laboratory setting using an Analytical Spectral Devices (ASD) FieldSpec® 4 Hi-Res and Ocean Optics OCEAN-HDX-VIS-NIR® (HDX), suitable for comparison to other spectroradiometer measuremen
Two spectroradiometers, a Malvern Panalytical Analytical Spectral Devices FieldSpec® 4 Hi-Res (hereafter referred to as ASD spectrometer) and a high sensitivity spectrometer, OCEAN-HDX-VIS-NIR®, from Ocean Optics (hereafter referred to as HDX) were used to collect reflectance measurements of materials in a controlled indoor setting at the USGS Spectroscopy Lab in Denver, Colorado on July 8, 2022 t
Data and analytical code associated with pinyon jay local-scale density-habitat relationship model (2008 - 2020) in the InterMountain West, USA
This data release provides pinyon jay (Gymnorhinus cyanocephalus) counts and local-scale vegetation data associated with summertime point count surveys conducted throughout the InterMountain West under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program, 2008 - 2020. We also provide code written in the R programming language to model pinyon jay abundance as a function of local-s
Surficial geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado
This data release presents geologic map data for the surficial geology of the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado, and an adjacent area to the north of the Blanca Peak quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains Province, and the Great Plains Province, Raton Section. Geologic mapping is
Post-fire debris-flow hazard model output files, Santa Fe Municipal Watershed, New Mexico
Wildfires are increasing in size and severity because of a warming climate in combination with overstocked forests. Fire increases the likelihood of debris flows, posing significant threats to life, property, and water supplies. Post-fire debris flows are a substantial, increasing hazard in the Santa Fe Municipal Watershed and other similar forested watersheds across the western United States. The
Urban tree cover provides consistent mitigation of extreme heat in arid but not humid cities - data release
Urban land cover types influence the urban microclimates. However, recent work indicates the magnitude of land cover’s microclimate influence is affected by aridity. Moreover, this variation in cooling and warming potentials of urban land cover types can substantially alter the exposure of urban areas to extreme heat. Our goal is to understand both the relative influences of urban land cover on lo
