Post-release point locations and survival history of fishers translocated from British Columbia to Olympic National Park, Washington, 2008-2010

The data set includes point location data and survival status of 90 fishers that were translocated from central British Columbia, Canada, to Olympic National Park, Washington, 2008-2010.

Mercury in fishes from Clear Lake, California, 2019 and 2020

Comma-separated values (.csv) file containing data related to mercury in fishes collected from Clear Lake, California.

Detection/non-detection data on territorial pairs of golden eagles in coastal southern California, 2016-2017

This dataset contains detection-nondetection data for territorial pairs of Golden Eagles at survey sites randomly selected from a grid of equal-sized (13.9 km2) hexagonal sample cells overlaid across the region of interest in Coastal Southern California during 2016 and 2017. We partitioned surveys within seasons based on approximate transition dates for stages in the breeding cycle of golden eagle

Effects of rotenone on nesting Ospreys (Pandion haliaetus) at Hyatt and Howard Prairie Reservoirs, OR, 1988-1992

To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre-treatment (1988,

Riverscape snorkeling surveys of salmonid distribution and abundance before (2007, 2008) and after (2018, 2019) dam removal on the Elwha River, Washington

We used snorkel surveys in the Elwha River, conducted in consecutive years before (2007, 2008) and after (2018, 2019) dam removal to assess changes in fish distribution and density. In total, we counted 54,616 Chinook Salmon, Bull Trout, Steelhead, and trout (Rainbow Trout and Coastal Cutthroat Trout combined) in 22 common reaches spanning 65 river kilometers. The occupancy of juvenile Chinook Sal

Invasive Grasses Cheatgrass and Medusahead Yield Responses to Sucrose in Experimental Plots in the Northern Great Basin, USA Dataset, 2005-2006

Comma-separated values (.csv) files containing data related to plant biomass and seed production responses of invasive Bromus tectorum (cheatgrass) and Taeniatherum caput-medusae (medusahead) to varying sucrose treatments.

Bird Responses to Young Stand Thinning in Western Oregon in 2013

The US Forest Service, Pacific Northwest Research Station, and Oregon State University established the Young Stand Thinning and Diversity Study (YSTDS) in 1990 to demonstrate and test options for young stand management in western Oregon. The YSTDS is designed to determine if different thinning, underplanting, and snag creation treatments in 35-50 year-old plantations can accelerate the development

Stream Temperature in the Lahontan Basin of Nevada and California, 2017-2019

This dataset includes hourly stream temperature data for 139 temperature logger sites throughout the Lahontan Basin Region of Northern Nevada and Eastern California. Data loggers were part a study beginning in 2017, with data available through 2019 for most locations. The spatial data layer contains site locations, geographic information, data summaries, mean August stream temperatures, and modele

Presence and cover of exotic annual and perennial grass species during five years post-fire on the Soda Wildfire

Data includes cover and presence (within microsites and 13 m radius plots) of three exotic annual grass, Bromus tectorum, Taeniatherum caput-medusae, and Ventenata dubia and presence (within microsites) of four perennial bunchgrass species (Agropyron cristatum, Pseudoroegneria spicata, Poa secunda, Elymus elymoides) within the first five years after the 2015 Soda wildfire. Additional landscape and

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 and fungi

Location of agricultural land cover obtained from the LANDFIRE Existing Vegetation Type dataset.

Mesocarnivore Survey of Crater Lake National Park, Klamath Network, 2016

Remote camera stations were set up in Crater Lake National Park from June to October 2016 to document occurrence of mesocarnivores and other wildlife. 124 cameras were set up at 31 primary sampling units (clusters of 4 cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The dataset contains all species observed within
