Projections of post-fire cover of non-native short-lived grasses and forbs under current and future climate conditions 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....
Radiocarbon dating of silicified wood from around Artemisia Geyser in the Upper Geyser Basin, Yellowstone National Park Radiocarbon dating of silicified wood from around Artemisia Geyser in the Upper Geyser Basin, Yellowstone National Park
Samples of silicified wood remnants from 8 trees were collected under research permit YELL-SCI-8030 on June 17, 2023, and on September 19, 2023 adjacent to Artemisia Geyser in the Upper Geyser Basin of Yellowstone National Park. Samples were collected for radiocarbon (14C) dating of the wood to determine when the trees grew. Trees do not grow on active geyser mounds (Hurwitz and others...
Laboratory-based optical measurements for surface water samples collected within the Fraser River in the Upper Colorado River Basin from September 2021 through September 2023 Laboratory-based optical measurements for surface water samples collected within the Fraser River in the Upper Colorado River Basin from September 2021 through September 2023
Optical spectra reported here are collected from 17 surface water sampling sites within the Fraser River, a headwaters drainage of the Upper Colorado River Basin in the central western United States. The sample collection was conducted as part of the partnership between the United States Geological Survey’s (USGS) Next Generation Water Observation System (NGWOS) and Proxies Project, in
Whole rock geochemistry for the Central Death Valley volcanic field, California (ver. 2.0, February 2026) Whole rock geochemistry for the Central Death Valley volcanic field, California (ver. 2.0, February 2026)
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.
Geomorphic Model Archive, Kootenai River near Bonners Ferry, Idaho, 2011-2022, model archive Geomorphic Model Archive, Kootenai River near Bonners Ferry, Idaho, 2011-2022, model archive
Between 2011 and 2018, numerous restoration treatments were constructed in the Straight and Braided and Straight Reaches of the Kootenai River in northern Idaho as part of the Kootenai River Habitat Restoration Project. Led by the Kootenai Tribe of Idaho, the project aimed to address a range of anthropogenic impacts inhibiting natural recruitment of the critically endangered Kootenai...
Estimated current and future environmental suitability of pinyon and juniper tree species for 3 emission scenario pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) across the western North America Estimated current and future environmental suitability of pinyon and juniper tree species for 3 emission scenario pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) across the western North America
These data were compiled to provide gridded estimates of environmental suitability for pinyon-juniper species in western North America. These gridded suitability projections provide estimates of suitability under current climate conditions and future climate conditions and allow for visualization of suitability change across each species’ entire range. These data consist of gridded...
