Data

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,

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

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.

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

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

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

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

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

Remote camera stations were set up in Lava Beds National Monument and Modoc National Forest from January to May 2018 to document occurrence of mesocarnivores and other wildlife. Thirty-three cameras were set up at 12 primary sampling units (clusters of one to four cameras) throughout the park. Potentially suitable habitat occurred in small patches in Lava Beds National Monument with cameras were p

Remote camera stations were set up in Lassen Volcanic National Park from August to October 2017 and June to September 2018 to document occurrence of mesocarnivores and other wildlife. 126 cameras were set up at 32 primary sampling units (clusters of two to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The d

Remote camera stations were set up in Whiskeytown National Recreation Area from October 2018 to January 2019 to document occurrence of mesocarnivores and other wildlife. Forty-five single-camera sampling stations were setup throughout the park. Camera locations were chosen based on the Klamath Monitoring Network vegetation plots. The dataset contains all species observed within the study time-fram

Remote camera stations were set up in Oregon Caves National Monument and Preserve from February through April 2017 to document occurrence of mesocarnivores and other wildlife. Fifteen cameras were set up at four primary sampling units (clusters of three to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The d
