Vegetation data from Columbia spotted frog (Rana luteiventris) exclosure study in eastern Oregon Vegetation data from Columbia spotted frog (Rana luteiventris) exclosure study in eastern Oregon
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...
Streamflow Observation Points in the Pacific Northwest, 1977-2016 Streamflow Observation Points in the Pacific Northwest, 1977-2016
This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.
Stream temperature and drying data from Willow/Whitehorse watersheds, southeast Oregon, 2014-16, and Willow/Rock/Frazer watersheds, northern Nevada, 2015-2016 Stream temperature and drying data from Willow/Whitehorse watersheds, southeast Oregon, 2014-16, and Willow/Rock/Frazer watersheds, northern Nevada, 2015-2016
These tabular, spatial, and code data sets were created in support of a stream temperature and drying study that took place in the Willow and Whitehorse watersheds of southeastern Oregon from 2014-2016 and the Willow, Rock, and Frazer watersheds of northern Nevada from 2015-2016. A prior data release of stream temperature data and associated spatial data from the Willow and Whitehorse...
Created snag characteristics and cavity-nesting bird associations in the CFIRP stands, McDonald-Dunn Research Forest, Corvallis, OR, USA, 2016 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 (20...
Compilation of BLM Monitoring Reports Assessing Post Wildfire Seeding of Rangelands, 2001-2009 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...
Compilation of studies assessing post-wildfire seeding of rangelands worldwide (1965-2010) 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...
Count and detection-nondetection survey data of barred owls (Strix varia) in historical breeding territories of Northern Spotted Owls (Strix occidentalis caurina) in the Oregon Coast Range, 1995-2016 Count and detection-nondetection survey data of barred owls (Strix varia) in historical breeding territories of Northern Spotted Owls (Strix occidentalis caurina) in the Oregon Coast Range, 1995-2016
This dataset contains count and detection-nondetection data of Barred Owls from 106 historical breeding territories of Northern Spotted Owl territories (i.e. sites) in the Oregon Coast Ranges from 1995 to 2016. Data collected from 1995 to 2014 are partitioned into 2-week periods from 1 March - 31 August each year, totaling 12 possible sampling periods per year. Data collected from 2015...
Combined wildfire dataset for the United States and certain territories, 1870-2015 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...
Avian abundance and oak mistletoe survey data from the Willamette Valley, Oregon, 2013-2015 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...
Nitrogen cycling rates from sagebrush and cheatgrass-invaded soils in the Northern Great Basin (2008) 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 soil bacteria...
Summary of Total Mercury Concentrations in Dragonfly Larvae, Western Mosquitofish, and Tree Swallow Eggs Collected from Cosumnes River Preserve 2011 2013 Summary of Total Mercury Concentrations in Dragonfly Larvae, Western Mosquitofish, and Tree Swallow Eggs Collected from Cosumnes River Preserve 2011 2013
The Cosumnes River Preserve in the Californias Central Valley contains a mosaic of managed wetlands where conditions may promote high levels of methylmercury bioaccumulation. In order to document potential environmental health risk in these wetlands due to mercury, we analyzed dragonfly larvae, western mosquitofish, and tree swallow eggs collected from wetlands and rice fields of the...
Oregon Spotted Frog Monitoring in the Oregon Cascades 2012-2016 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.
