Western US Ruggedness Raw Values

"Vector Ruggedness Measure (VRM) measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures variability in slope and aspect into a single measure. Ruggedness values in

Pacific Northwest Avian Scavenger Lead and Mercury Dataset, 2012-2016

The dataset includes the bird species, region where sampled, sampling site, capture location, mercury concentration in whole blood, lead concentration in whole blood, sulfur stable isotope concentration in blood plasma, carbon isotope concentration in blood plasma, whole blood ALAD activity, and fecal corticosterone concentrations.

Forest management and cervid herbivory data from Western Oregon, USA, 2012 (Community Data)

Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that intensive forest management and large herbivores have compounding effects on early-seral plant communities and plantation establishment (i.e., tree

Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2018

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the

DNA yields and concentrations from buccal swab samples of Red-Cockaded Woodpeckers

The data were generated as part of a study to determine if buccal (oral) swabs could be used to obtain genetic material from Red-Cockaded Woodpecker chicks. Different swab types were investigated to determine if any specific type gave the highest DNA yields.

Disturbance characteristics, vegetation and biocrust cover from the northern Great Basin (USA) 2012-2013

Fifteen fires from the Chronosequence dataset (see Knutson et al. 2014) were visited in 2012 and 2013 and surveyed for cover of lichens and mosses. Fires were selected to cover the range of average precipitation for each of three water years following fire, fire severity, time since fire, season of ignition, total acres burned and grazing intensity. Cattle grazing was characterized by

Nest success and predation data for Mariana swiftlets (Aerodramus bartschi), Hawai'i, USA, 2006-2010

This study examined the reproductive biology of the Mariana Swiftlet over five annual cycles on the island of O‘ahu in the Hawaiian Islands. This introduced population used a human-made tunnel for roosting and nesting, and was studied as a surrogate to negate interference with the endangered populations in the Mariana Islands. Active nests (N = 478) were observed in every month of

Exotic and perennial grass cover for pastures in the Soda Fire (2016)

The point data file ("Soda Fire Point and Pasture Data (2016).Point Data.csv") includes 2016 vegetative cover values of exotic annual grass and perennial grass measured within three different types of plots for 75 pastures in the Soda Fire, which burned in 2015: 6m² plot using a grid-point intercept photo software, SamplePoint (Booth et al. 2006), 1m² quadrat usi

Probability of Streamflow Permanence (PROSPER) Model Output Layers

The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions...
