Native plant revegetation at Butterfly Meadows (Benton County), habitat for the endangered Fender's blue butterfly

Creator:: Clark, Deborah Louise, 1950-
Abstract:: Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon's ecosystems and are in critical need of conservation. One of the largest remaining parcels of native upland prairie, Butterfly Meadows (Benton County), is being invaded by Brachypodium sylvaticum (false brome). This site...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Management of Tall Oatgrass Arrhenatherum elatius in Willamette Valley Prairies: Preliminary Report. A component of the project Restoration and Vegetation Management of Fender's Blue Butterfly Habitats

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon's ecosystems. Even though only remnants remain today, they harbor rare and endangered species such as the Fender's blue butterfly (Icaricia icariodes fenderi) and its preferred host plant, Kincaid's lupine (Lupinus sulphureus ssp....

Final report [year one]: Control of Brachypodium sylvaticum and restoration of rare native upland prairie habitat at Butterfly Meadows, Benton County ODA 1342 GR

Creator:: Clark, Deborah Louise, 1950-, Hammond, Paul, Johnson, Deborah, Kaye, Tom, Kelpsas, Bruce, Pfund, Fred, Vomocil, Marc, and Wilson, Mark V.
Abstract:: Our project goal is to protect and restore rare Willamette Valley upland prairie habitat at Butterfly Meadows (Benton County) from invasion by the noxious weed Brachypodium sylvaticum (false brome). Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon’s ecosystems and are...

Phytophthora ramorum colonizes tanoak xylem and is associated with reduced stem water transport

Creator:: Parke, J. L., Oh, E., Voelker, S., Hansen, E. M., Buckles, G., and Lachenbruch, Barbara
Abstract:: Isolation, detection with diagnostic polymerase chain reaction (PCR), and microscopy demonstrated the presence of Phytophthora ramorum in the sapwood of mature, naturally infected tanoak (Lithocarpus densiflorus) trees. The pathogen was strongly associated with discolored sapwood (P < 0.001), and was recovered or detected from 83% of discolored sapwood tissue samples....

Strobilus production and growth of Pacific yew under a range of overstory conditions in western Oregon

Creator:: DeFazio, S. P., Vance, N. C., and Wilson, M. V.
Abstract:: Strobilus production, growth, and morphology of Pacific yew (Taxus brevifolia Nutt.) were examined at three sites in the Cascade Mountains and one site in the Willamette Valley of western Oregon. Strobilus production on branch segments was positively associated with overstory openness for male and female trees at all four sites...

Cryptogam communities in forest and steppe ecosystems of Oregon, USA

Creator:: Root, Heather T.
Abstract:: I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...
