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...

Final Report: Controlling Tall Oatgrass in Fender’s Blue Butterfly Habitats

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: We report final results from a five-year field experiment evaluating the effects of different mowing regimes on groups of native and non-native grasses and forbs. The study site was a degraded prairie at Baskett Slough National Wildlife Refuge dominated by the pest plant Arrhenatherum elatius (tall oatgrass). Mowing treatments differed...

Final Report for the project: Research on Habitat Manipulation and Management of Fender's Blue Butterfly Areas

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: We report first-year results from two field experiments evaluating the effectiveness of various techniques for the control of pest plants in Fender's blue butterfly habitat. In the woody-plant study, we monitored the effects of mowing, mowing and herbicides, and burning on woody plants and key native and non-native grasses and...

Final Report 1994-1997: Effects of Fire, Mowing, and Mowing with Herbicide on Native Prairie of Baskett Butte, Baskett Slough NWR

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
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...

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...

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...

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....

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,...

Increasing the abundance of rare native wetland prairie species

Creator:: Clark, Deborah Louise, 1950-, Wilson, Mark V., and Goodridge, Jennifer
Abstract:: 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...

Final report: Restoration of Fender’s blue butterfly and its prairie ecosystem: Management applications of fire to Baskett Slough NWR

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: We tested the recolonization ability of the Fender’s blue butterfly and monitored the vegetation response to a management-scale prescribed fire at the Baskett Slough National Wildlife Refuge, western Oregon. The prescribed fire successfully cut shrub cover in half, but also reduced the size of Festuca roemeri, a dominant native grass....
