Beaver-related Stream Restoration Projects in Western Rangelands

We systematically surveyed federal and state wildlife biologists, hydrological specialists, non-profit organizations, and working groups focused on beaver or wetland restoration in the western U.S. We focused primarily on contacting land managers from states containing some portion of the Great Basin, although many of the projects described in surveys fell outside of this watershed. Some...

Western US Ruggedness Reclassified into 6 Classes

"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 the...

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 using an...

Insect and vegetation community composition and abundance after wildfire and restoration seeding treatments in southwestern Idaho, USA

We conducted the first investigation of insect community responses to post-fire seeding on public rangelands by comparing the composition of insect communities at burned-and-seeded (treatment) and burned-and-unseeded (control) sagebrush-steppe ecological sites in southwestern Idaho. Insect communities in burned areas were compared to unburned (reference) areas. We collected insect and...

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...

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 distance...

Mariana swiftlet (Aerodramus bartschi) survey data from O'ahu, Hawai'i, 2005-2010

The data set contains Mariana swiftlet (Aerodramus bartschi) population survey data that were collected via evening arrival surveys on the island of O'ahu, Hawaiian Islands. Data were collected at a roosting/nesting tunnel used by Mariana swiftlets in North Halawa Valley.

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...

Western US 30m Raw Heatload Values

Heat load, a unitless value from approximately 0 (low incident radiation) to around 1 (high incident radiation), is calculated using aspect, slope, and latitude (McCune and Dylan 2002 ).

Columbia Spotted Frog (Rana luteiventris) Breeding at Grazing Exclosures in Eastern Oregon 2002-2010 and 2013

We studied the short-term effects of full and partial livestock grazing exclosures on Columbia Spotted Frog (CSF; Rana luteiventris) populations using a controlled manipulative field experiment with pre- and post-treatment data. This dataset includes vegetation data collected 2002-2010 and 2013 at 94 lakes and ponds in and around the Blue Mountains in eastern Oregon. Data collection followed...

Genetic data from Red-cockaded woodpeckers (Dryobates borealis) used to assess changes in population genetic differentiation and diversity over the past century throughout the southeastern United States.

These data include nuclear microsatellite data and mitochondrial DNA sequences (mtDNA) for specimens of Red-cockaded woodpeckers collected from three time points: 1881-1969 (mtDNA only), 1992-1994, and 2010-2014. Additional information regarding individual identifiers, population assignment, regional assignment, and eco-regional assignment are included as are longitude/latitude coordinates for...

Telemetry and habitat data for Oregon spotted frogs (Rana pretiosa) in Oregon, USA

We used radio-telemetry to study late-season movement and habitat use by the Oregon spotted frog (Rana pretiosa) at 9 sites from 4 populations along the Cascade Mountains in Oregon. This dataset includes individual frog morphometrics, location data, and habitat use during each tracking event that occurred roughly weekly between September and January of 2011, 2012, and 2016.
