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. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

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...
