Compilation of BLM Monitoring Reports Assessing Post Wildfire Seeding of Rangelands, 2001-2009

Post-fire rehabilitation seeding in the U.S. Intermountain West, primarily conducted by the Bureau of Land Management, is designed to reduce the risk of erosion and weed invasion while increasing desirable plant cover. Seeding effectiveness is typically monitored for three years following treatment, after which a closeout report is prepared. We evaluated 220 third-year closeout reports...

Electrical resistance data from the Willow-Whitehorse watersheds of southeast Oregon, USA, 2014-2016

This dataset includes electrical resistance data from a network of 50 data loggers that was installed throughout the Willow-Whitehorse watershed of SE Oregon in September 2014. Data loggers were downloaded in August 2015 and September 2016. These data loggers were used as “electrical resistance” (ER) sensors, following Chapin et al. 2014. The sensors were Onset HOBO...

Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2016

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2016 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 aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the time each survey.

Simulated data supporting inbreeding rate estimates from incomplete pedigrees

This data release includes the data from simulations used to illustrate the behavior of inbreeding rate estimators and Python source code ("analytical expressions", "computer simulations", and "empricial data set") that can be used to analyze these data.

Raster digital data sets identifying a range-wide network of priority areas for greater sage-grouse

We used graph theory, representing priority areas as spatially distributed nodes interconnected by movement corridors, to understand the capacity of priority areas to function as connected networks in the Bi-State, Central, and Washington regions of the Greater Sage-Grouse range.

Created snag characteristics and cavity-nesting bird associations in the CFIRP stands, McDonald-Dunn Research Forest, Corvallis, OR, USA, 2016

Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function and structure of created snags across long time periods (>...

Stream temperature data in Willow/Rock/Frazer watersheds of northern Nevada, 2015-16

This dataset includes stream temperatures from a network of 112 data loggers that was installed in stream channels throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Ninety-seven data loggers were recovered and downloaded in late July 2016.

Combined wildfire dataset for the United States and certain territories, 1870-2015

The increase in wildfires, particularly in the western U.S., represents one of the greatest threats to multiple native ecosystems. Despite this threat, there is currently no central repository to store both past and current wildfire perimeter data. Currently, wildfire boundaries can only be found in disparate local or national datasets. These datasets are generally restricted to specific...

Oregon Spotted Frog Monitoring in the Oregon Cascades 2012-2016

This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Data consist of spotted...

Avian abundance and oak mistletoe survey data from the Willamette Valley, Oregon, 2013-2015

This dataset includes two spreadsheets: The "Avian_abundance_oak_mistletoe_bird_data" spreadsheet contains data regarding Oregon White Oak tree (Quercus garryana) measurements such as height, diameter and crown volume along with microhabitat data including number of mistletoe infections, number of cavities, amount of dead wood, amount of loose/missing bark, amount of poison oak, amount of bole...
