High resolution fractional tree cover and change over time for Olympic, Mount Rainier, and Glacier National Parks
High resolution fractional tree cover and change over time for Olympic, Mount Rainier, and Glacier National Parks from the mid-1980s to the mid-2020s. Date of annual snapshots of tree cover and the temporal range of change over time in tree cover vary by location. See metadata files associated with individual parks for specific details.
Bumble bees and flowering plants on Montana rangelands, 2023-2024 (ver. 3.0, March 2025)
USGS personnel surveyed bumble bees and flowering plants on private and public lands in Central Montana during the spring and summer of 2023 and 2024. These data provide a summary of what was found, including the number of bumble bees caught during standardized netting surveys and a comprehensive list of all plants in flower within survey plots during each site visit. First release: 2023...
Radar-determined locations of flying animals along the eastern edge of the Rocky Mountains, Wyoming, 2023 and 2024
A pair of modified marine radars were deployed at two locations, the Clark's Fork Fish Hatchery (near Powell, Wyoming) and the Timber Creek Ranger Station (near Meeteetse, Wyoming), during the summer of 2023 and 2024. The radars collected data on flying animals with a focus on army cutworm (Euxoa auxiliaris) moths within a couple kilometers of the radars during most of the army cutworm...
Ungulate Migrations of the Western United States, Volume 5
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 5 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and...
Radar-determined locations of flying animals over the Gulf of America, 2023 and 2024
A modified marine radar was deployed on the National Oceanic and Atmospheric Administration research vessel, Gordon Gunter, during the fall of 2023 and 2024 as it transected the Gulf of America conducting benthic surveys. The radar collected data on avifauna (and flying animals generally) within a couple kilometers of the vessel during a portion of the fall migration. Data collected can...
Rocky Mountain bighorn sheep datasets from Dinosaur National Monument, Colorado, Utah, USA, 2006-2022
Tabular and raster data containing spatial capture recapture, GPS telemetry, ground observations, and genetic records for male and female Rocky Mountain bighorn sheep (Ovis canadensis canadensis) in Dinosaur National Monument from 2006 to 2022. Includes associated tabular data files required for analysis of data with spatial capture models and resource selection models, and the raster...
Streambed and suspended sediment data from streams in western Montana from 2018
This data release contains streambed sediment data, suspended sediment data, and stream stage data from tributary streams in Western Montana. These datasets were created to assess the linkages between unpaved roads and instream sediment distributions. Surveys were collected in tributaries and rivers within the Clearwater River and Swan River basins in Montana. Site locations were...
Fish sampling data, water temperature data, and groundwater spring location data from the upper Snake River basin, WY, 2021-2023
Fish sampling data, stream temperature data, and observations of the locations of groundwater springs within the upper Snake River basin, Wyoming. These datasets were created to assess how stream temperature and groundwater spring sources are associated with the growth and production of young-of-year Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri; formerly Oncorhynchus...
Environmental DNA qPCR concentration results and environmental covariates from a Montana headwater stream sampled in 2023
Environmental DNA quantitative results at the PCR technical replicate level for the target species Arctic Grayling and covariate information associated with these eDNA samples.
Environmental DNA qPCR detection results and covariates from Idaho, Missouri, Montana, and New York rivers sampled in 2023
This dataset contains quantitative results from, and covariate attributes of, environmental DNA water samples collected across multiple rivers in 2023. Samples were analyzed for eDNA of round goby in the Hudson River (NY), westslope cutthroat trout (Oncorhynchus clarkii lewisi) in Cherry Creek (MT), lake trout (Salvelinus namaycush) and Spectaclecase mussels (Cumberlandia monodonta) in...
Winter Tick Host Competency Data from Elk and Moose in the Southern Greater Yellowstone Ecosystem 2020-2023
Three tabular datasets providing tick counts from various transects and reproduction sites around Jackson, Wyoming. One table with data from total number of winter ticks collected running a transect along either an elk or moose hide, another table with winter tick counts collected and counted in a 250 m drag transect, and then the last table is the count of larvae that come from one fed...
Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings
In the Rocky Mountains of the Greater Yellowstone Ecosystem (United States), recent melting at a high-elevation (3,091 m asl) ice patch exposed a mature stand of whitebark pine (Pinus albicaulis) trees located ~180 m above modern treeline dating to the mid-Holocene (c. 5,900-5,436 cal y BP +- 51 y). From this subfossil wood record, we contextualize the recent magnitude of warming...
