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.

Riparian seed dispersal phenology and snowmelt streamflow timing in the upper South Platte River Basin, observed in 2010-2011 and simulated for 1962-2098 Riparian seed dispersal phenology and snowmelt streamflow timing in the upper South Platte River Basin, observed in 2010-2011 and simulated for 1962-2098
This dataset presents observations and model projections of climate, riparian cottonwood and willow seed release phenology, snowmelt streamflow timing, and relative timing of seed release and snowmelt peak streamflow in the upper South Platte River Basin, USA. We collected field observations of seed release phenology from three riparian Salicaceae species at 14 riparian sites and used...
Lignin phenol data for solid phase peat cores collected from the Alligator River and Great Dismal Swamp National Wildlife Refuges Lignin phenol data for solid phase peat cores collected from the Alligator River and Great Dismal Swamp National Wildlife Refuges
This dataset includes lignin phenol monomer concentrations normalized to 100 mg of organic carbon. These analyses were conducted on select intervals from peat cores collected at the Alligator River (AR) and Great Dismal Swamp (GDS) National Wildlife Refuges in North Carolina and Virginia/North Carolina, USA, respectively. The eight lignin phenol monomers provide unique proxy information...
Riparian vegetation, topography, sediment quality, and river corridor geomorphology in the Lower Virgin River, Nevada and Arizona, before (2010) and after (2011-2012) a 40-year return period flood Riparian vegetation, topography, sediment quality, and river corridor geomorphology in the Lower Virgin River, Nevada and Arizona, before (2010) and after (2011-2012) a 40-year return period flood
The data release presents observations of riparian vegetation, topography, sediment quality, and river corridor geomorphology in four river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm) from near the town of Littlefield (AZ) and the Arizona-Nevada border at rkm 119. Methods included field observations and analysis of remotely-sensed data before (2010)...
Data for cheatgrass mapping in Squirrel Creek Wildfire and Arapaho Wildfire, WY in 2014 Data for cheatgrass mapping in Squirrel Creek Wildfire and Arapaho Wildfire, WY in 2014
This data bundle contains some of the inputs, all of the processing instructions and all outputs from a single VisTrails/SAHM workflow. This model specifically includes field data of locations with >40% cover of cheatgrass (presence) and
Paleoecological data from The Loch and Sky Pond, Rocky Mountain National Park Paleoecological data from The Loch and Sky Pond, Rocky Mountain National Park
Diatom taxonomy, carbon and nitrogen stable isotope values, and algal pigment data from lake sediment layers dating back to 1600 Common Era (CE) for Sky Pond and The Loch in Rocky Mountain National Park.
Hierarchically nested and biologically relevant monitoring frameworks for Greater Sage-grouse, 2019, Nevada and Wyoming, Interim Hierarchically nested and biologically relevant monitoring frameworks for Greater Sage-grouse, 2019, Nevada and Wyoming, Interim
We developed a hierarchical clustering approach that identifies biologically relevant landscape units that can 1) be used as a long-term population monitoring framework, 2) be repeated across the Greater sage-grouse range, 3) be used to track the outcomes of local and regional populations by comparing population changes across scales, and 4) be used to inform where to best spatially...
popcluster: Developing Hierarchical Population Monitoring Frameworks for mobile species with high site fidelity popcluster: Developing Hierarchical Population Monitoring Frameworks for mobile species with high site fidelity
The software "popcluster" constructs hierarchically nested groupings of similar habitats associated with field surveys while considering biological structure/connectedness (movements between habitats). This approach can support mobile species with high site fidelity where monitoring during surveys occurs on birthing grounds, breeding grounds, or stopovers/seasonal habitat for migratory...
Abundance of wetland-dependent birds at Breeding Bird Survey routes and associated land cover and climate information Abundance of wetland-dependent birds at Breeding Bird Survey routes and associated land cover and climate information
Estimation and validation data for site by species matrices used in the publication 'Clustering and ensembling approaches to support surrogate-based species management' by H.R. Sofaer et al. 2019 Diversity and Distributions
Simulation to evaluate response of population models to annual trends in detectability Simulation to evaluate response of population models to annual trends in detectability
In 'Simulation to evaluate response of population models to annual trends in detectability', we provide data and R code necessary to create simulation scenarios and estimate trends with different population models (Monroe et al. 2019). Literature cited: Monroe, A. P., G. T. Wann, C. L. Aldridge, and P. S. Coates. 2019. The importance of simulation assumptions when evaluating...
Croton setiger predators, herbivores, and damage collected in California 2013-2014 Croton setiger predators, herbivores, and damage collected in California 2013-2014
A pollen addition experiment was conducted on the leaves of Croton setiger, a Californian forb. Pollen was added to leaves of randomly selected plants, and control plants had no pollen added. Over 2013 and 2014 the number of predatory and herbivorous insects were counted on each plant, and the number of damaged leaves and plant size were measured.
Habitat characterization around standard brown treesnake traps on Guam, 2004 - 2017 Habitat characterization around standard brown treesnake traps on Guam, 2004 - 2017
Data were collected in association with locations of standard brown treesnake traps on Guam at location prior to suppression or control efforts and after control had occurred. In all cases study sites were closed or semi-closed populations of brown treesnakes. Habitat data focused on type and structure of the habitat within 10-m of the trap.
Laboratory Incubation results from 2015 for bacterial cell counts, carbon use efficiency, growth efficiency, and dissolved organic matter chemistry from four glacier outflows and four rock glacier outflows in Colorado Laboratory Incubation results from 2015 for bacterial cell counts, carbon use efficiency, growth efficiency, and dissolved organic matter chemistry from four glacier outflows and four rock glacier outflows in Colorado
Bacterial Data include results of incubations of lakewater bacteria with dissolved organic matter extracted from Colorado glacier or rock glacier outflows in 2015. Cells were counted pre- and post- incubations. The "Counts" tab is the number of cells counted in each view of the microscope using the acridine orange method. "C Calculations" tab is the calculation of carbon as bacterial...
