This thesis uses a hedonic price model to estimate the value of water for irrigation in Deschutes County, Oregon. The analysis uses a dataset comprising information on 2,274 agricultural parcels across the County. Uniquely, the analysis successfully utilizes assessor-determined real market values in the place of actual land sales. A...
Numbers of invertebrates (except family Carabidae) collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, site and trap ID, trap type, taxonomy (at least order level) and life stage.
Numbers of carabid beetles, caterpillars, cranefly larvae and slugs collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, trap, size and sex (carabids only), weight (slugs only) and species (where...
Between 43° 17' and 43° 21' north latitude along the south-central coast line of Oregon lie the collecting grounds adjacent to the Oregon Institute of Marine Biology. These 10 miles of coast line, between Coos Bay and Cape Arago, provide an assortment of intertidal environments ranging from the protected brackish...
Lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many as hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. Historical, cultural, and biological information for the twentieth...
This dataset contains records of identified benthic and aquatic emergent invertebrates from pre-timber harvest, post-timber harvest, and reference (no harvest) collection sites in the Hinkle Creek watershed. A variety of fish-bearing tributaries, fishless tributaries, and mainstem creek sites were sampled. Benthic invertebrates were collected using Serber nets and emergent adults...
Isotope and stomach content data from piscivorous reservoir fishes collected from Hills Creek (isotopes; 43°40′16″N 122°25′33″W) and Lookout Point (isotopes and stomach contents; 43°53′48″N 122°43′34″W) reservoirs located on the Middle Fork Willamette River, Oregon. Additional details can be found in the related publication.
Isotope sampling was conducted under OSU Institutional...
High-resolution measurements of salinity, temperature, and partial pressure of carbon dioxide (pCO2) taken at Whiskey Creek Shellfish Hatchery, Netarts Bay, Oregon, from 2014 - 2019 are provided in this data set. Briefly, a permanently submerged pipe draws in bay water to supply the shellfish hatchery tanks. Unmodified water is branched...
Question: Most results of restoration efforts are species-specific and/or site-specific and therefore are not general enough to be easily applied to other species and other sites. Our research addresses the issue of species-specific results by investigating the feasibility of using plant traits instead of taxonomic species to characterize species responses...
Questions: Are traits related to the performance of plant species in restoration? Are the relationships between traits and performance consistent across the functional groups of annual forbs, perennial forbs, and grasses? Do the relationships between traits and performance depend on neighboring functional groups? Location: A former agricultural field, being restored...
Native prairies of the Willamette Valley are considered among the rarest of Oregon’s ecosystems and are in critical need of conservation. Management strategies for increasing the abundance of native species are urgently needed, particularly those strategies that promote the regeneration of native species from seed. Fire may be an important...
Samples targeting crustacean zooplankton were collected from 3 upper Willamette Basin reservoirs during May-August 2015. Van Dorn sampling devices were used to collect samples at discrete depths from Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir.
Zooplankton samples were collected during daytime and nighttime corresponding with the new...
Water chemistry measurements taken at or downstream of Fall Creek Reservoir, OR (43.9459714, -122.755765). Fall Creek is a tributary of the Middle Fork Willamette River, located approximately 20 miles SE of Eugene, Oregon, USA.
Water chemistry measurements included water samples collected from the reservoir outflow (during autumn drawdown) and within...
The Willamette Valley (Oregon) Prairie Plant Trait Dataset is a compilation of plant traits of species important in upland prairies, wetland prairies, vernal pools, and emergent wetlands, and in the restoration of prairies and wetlands of the Willamette Valley of Oregon. These species are also found widely throughout the Pacific...
This study tested multiple hydrologic mechanisms to explain snowpack dynamics in extreme rain-on-snow floods, which occur widely in the temperate and polar regions. We examined 26, 10 day large storm events over the period 1992–2012 in the H.J. Andrews Experimental Forest in western Oregon, using statistical analyses (regression, ANOVA, and...
