Controlling woody vegetation in wetland prairies, 1994-1999

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

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...

Fire effects on wetland prairie species : final report

Creator:: Clark, Deborah L., Wilson, Mark V., and Clark, Deborah Louise, 1950-
Abstract:: Wetland prairies of the Willamette Valley, considered among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native species. Because of its historical importance, fire is a top choice of managers for preventing the encroachment of woody species. However, the effects of prescribed burning on present...

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,...

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...

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

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
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. These are dynamic systems, subject to ecological succession and invasion by aggressive non-native species, and require active management to maintain management goals. This is true...

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...

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....

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...
