  • The Willamette Valley (Oregon) Prairie Plant Trait Dataset

    Creator:
    Clark, Deborah and Wilson, Mark V.
    Abstract:
    The Willamette Valley (Oregon) Prairie Plant Trait Dataset is a compilation of plant traits of species important in upland prairies, wetland prairies, vernal pools, and emergent wetlands, and in the restoration of prairies and wetlands of the Willamette Valley of Oregon. These species are also found widely throughout the Pacific...

  • 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...

  • 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...
