Repeat bathymetric surveys at 1-metre resolution of lava flows erupted at Axial Seamount in April 2011

Creator:: Caress, David W., Clague, David A., Paduan, Jennifer B., Martin, Julie F., Dreyer, Brian M., Chadwick, William W., Jr., Denny, Alden, and Kelley, Deborah S.
Abstract:: At sites with frequent submarine volcanic activity, it is difficult to discern between new and pre-existing lava flows. In particular, the distribution of the fissures from which lava erupts, the routes taken by lava flows and the relationship between the new flows and the pre-existing seafloor bathymetry are often unclear....

Recommendations for Control of Tall Oatgrass, Poison Oak, and Rose in Willamette Valley Upland Prairies

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: Native upland 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 many rare and endangered species such as the Fender's blue butterfly and its host plant, Kincaid’s lupine. Invasion of remnant prairies by...

Final report 1994-1996 : Effects of fire and fire fighting techniques on Fender's blue butterfly and Kincaid's lupine

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: We report results from a field experiment evaluating the effectiveness of mowing, mowing and herbicides, and burning on woody plants, key native and non-native grasses and forbs, and the Fender's blue butterfly. The goal was to find a technique that controlled woody pest plants without harming native species or promoting...

West Eugene Native Wetland Restoration Research Project: Seed Dormancy, Germination, and Establishment

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., and Clark, Deborah Louise, 1950-
Abstract:: Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...

Effects of Soil Nutrients and Fire on Seedling Establishment of Native Prairie Species

Creator:: Clark, Deborah Louise, 1950-
Abstract:: We sought to determine 1) the relationship between seedling establishment rates of target native prairie species and field levels of three soil nutrients (phosphate, nitrate, and ammonium) recorded in fall, winter, and summer, 2) the effect of fire on these three nutrients, and 3) the overall effect of fire on...

Demographic analysis of Erigeron decumbens var. decumbens, an endangered plant species of the Willamette Valley, Oregon: 1999 Field Studies

Creator:: Clark, Deborah Louise, 1950-
Abstract:: Erigeron decumbens var. decumbens, known only from the Willamette Valley of western Oregon, is listed as Endangered by the U.S. Fish and Wildlife Service and by the state of Oregon. In 1993 a long-term population monitoring program for Erigeron decumbens var. decumbens was initiated at Baskett Slough National Wildlife Refuge...

Controlling woody vegetation in wetland prairies, 1994-2001

Creator:: Clark, Deborah Louise, 1950-
Abstract:: Wetland prairies of the Willamette Valley, among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native pest species. Because fire has been important in maintaining Willamette Valley prairies for at least 1000 years, prescribed burning is a top choice of managers for preventing encroachment of...
