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...

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...

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...

Final report: Predicting field establishment rates from standardized plant traits - Year two of: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management

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,...

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...

Traits, neighbors, and species performance in prairie restoration

Creator:: Wilson, Mark V., Clark, Deborah Louise, 1950-, and Roberts, R. E.
Abstract:: 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...

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...

Creator:: Windham, George, Wagner, Jan, Ruzicka, Angela, Clark, Deborah Louise, 1950-, Wilson, Mark V., and Lederman, Norman
Abstract:: One goal of this environmental education curriculum is that students will gain an appreciation of Willamette Valley wetland prairies, a threatened ecosystem, and will gain an understanding of the importance of protecting these wetlands. A second goal is that students will see first-hand the processes involved in conducting scientific field...
