Post-dispersal seed fates in a Western Oregon native prairie

Creator:: Clark, Deborah L.
Abstract:: Knowledge of post-dispersal seed fates and other regeneration characteristics is crucial for predicting abundances and distributions of populations and, ultimately, community species composition and diversity. Seed fate studies, however, are rare primarily due to the difficulty of determining seed fates and causes of mortality. This thesis investigated post-dispersal seed fates...

Progress report II: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management (Year two)

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Willamette Valley wetland and upland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species. Because these are dynamic systems, subject to ecological succession and invasion by aggressive non-native species, prairies require active management to maintain management goals. This is...

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...

Regeneration biology of Erigeron decumbens var. decumbens, an endangered plant of the Willamette Valley

Creator:: Clark, Deborah Louise, 1950-, Finley, Karen K., and Ingersoll, Cheryl A.
Abstract:: Erigeron decumbens var. decumbens, the Willamette daisy, is known only from the Willamette Valley of Oregon. Herbarium records, from the 1800's until 1934, indicate that the Willamette daisy was once common and widely distributed throughout the Willamette Valley (Clark et al. 1993). However, between 1934 and 1980, this taxon was...

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...

Creator:: Wilson, Mark V., Clark, Deborah Louise, 1950-, and Roberts, Rachel E.
Abstract:: Willamette Valley wetland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species (Wilson et al. 1993, Noss et al. 1995, USFWS 2000, Schultz et al. 2003). A rigorous program of ecosystem restoration can protect and enhance wetland plants, animals,...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...

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...

Plant traits – a tool for restoration?

Creator:: Clark, Deborah Louise, 1950-, Wilson, Mark V., Roberts, Rachel, Dunwiddie, Peter W., Stanley, Amanda, and Kaye, Thomas N.
Abstract:: 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...
