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.

Probability of Streamflow Permanence (PROSPER) Continuous Parameter Grids (CPGs)

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...

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...

Habitat use, diet, movement, and vegetation use by western gray squirrels (Sciurus griseus) in the North Cascades Range, USA, 2008-2011

Data are contained in a comma-separated spreadsheet files (.csv) that describe vegetation characteristics of high- and low-use areas, nest tree sites, and individual nest trees used by western gray squirrels in the North Cascades as determined through live-trapping and radiotelemetry at two study sites: Stehekin, and the southern Methow Valley (Squaw Creek drainage), Washington. Squirrels were...

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 the...

Riparian Final Vegclass. Olympic National Park NRCA Westside Rivers Riparian Vegetation Project (2016)

Beschta and Ripple (2012) assert that increased elk populations in the Olympic National Park due to extirpation of wolves in the 1920’s has led to a reduction in riparian vegetation. They hypothesize that a decrease in this vegetation has led to an increase in erosion and undercutting of large conifer trees along the river banks, causing woody debris in the river, which in turn...

Forest management and cervid herbivory data from Western Oregon, USA, 2012 (Camera 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...

Occurrence locations and trait data for freshwater fishes, amphibians, and reptiles native to the state of Oregon

These datasets include occurrence points and trait data for freshwater fishes, amphibians, and reptiles native to Oregon State. Occurrence data were extracted from the VertNet database and include points within Oregon, Washington, and Idaho, as well as points found within ecoregions that overlap with Oregon state (U.S. EPA Level III EcoRegions). Occurrence points include records from years...

Fuels Database for Intact and Invaded Big Sagebrush Ecological Sites

The Fuels Guide and Database for Big Sagebrush Ecological Sites was developed as part of the Joint Fire Sciences Program project “Quantifying and predicting fuels and the effects of reduction treatments along successional and invasion gradients in sagebrush habitats” (Shinneman et al. 2015). The research was carried out by the U.S. Geological Survey (USGS) Forest and...

Vegetation cover data used from the Soil Vegetation Inventory Method (SVIM) for Southwest Idaho

The US Department of Interior’s (USDI) Bureau of Land Management (BLM) has a long history of soil and vegetation monitoring of public rangelands it manages. However, historical monitoring data have been stored and managed at the field, district, or state level, making them difficult to compile and analyze. BLM’s Soil Vegetation Inventory Method (hereafter SVIM) program...
