  • Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

    Creator:
    Bervid, Heather D.
    Abstract:
    Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows.

  • White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

    Creator:
    Viste-Sparkman, Karen
    Abstract:
    Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...
