  • Plant community dynamics in remnant and restored Willamette Valley wetland prairies

    Creator:
    Schwindt, Rachel A.
    Abstract:
    Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...

  • Patterns in responses of an amphibian assemblage to wetland restoration

    Creator:
    Rowe, Jennifer C.
    Abstract:
    Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...

  • Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

    Creator:
    Taft, Oriane Williams
    Abstract:
    Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...
