Nitrogen cycling rates from sagebrush and cheatgrass-invaded soils in the Northern Great Basin (2008)

This dataset contains data supporting the paper: DeCrappeo, N.M., DeLorenze, E.J., Giguere, A.T., Pyke, D.A., and Bottomley, P.J. Fungal and bacterial contributions to nitrogen cycling in cheatgrass-invaded and uninvaded native sagebrush soils of the western USA (accepted at the journal Plant and Soil). The purpose of the study was to evaluate the relative contributions of

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 spo

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.

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 Pendant

Temperature data loggers in Willow/Rock/Frazer watersheds of northern Nevada, 2015

This dataset includes spatial location information from 167 temperature data loggers that were installed throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 30 and August 14, 2015. One hundred twelve data loggers were installed in stream channels (some of which were dry), 50 data loggers were installed outside the stream channel to measure air temperature, a

Compilation of Studies Assessing Post Wildfire Seeding of Rangelands Worldwide, 1965-2010

Mitigation of ecological damage caused by rangeland wildfires has historically been an issue restricted to the western United States. It has focused on conservation of ecosystem function through reducing soil erosion and spread of invasive plants. Effectiveness of mitigation treatments has been debated recently. We searched for literature on postfire seeding of rangelands worldwide. Literature...

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 desc...

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.

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

This dataset includes air temperatures from 50 data loggers that were installed in tandem with stream temperature data loggers, as well as five ridgetop data loggers, throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Fifty-one data loggers were recovered and downloaded in late July 2016.
