Abstract or Summary
  • Oregon White Oaks (Quercus garryana) were once abundant in the Willamette Valley, Oregon, but have drastically decreased because of fire suppression, agriculture, and human development. Oaks are an important ecosystem because they provide a diverse habitat for bird species that are insectivorous and/or cavity nesters. We studied the oak restoration project at Pigeon Butte in Finley National Wildlife Refuge in Corvallis, Oregon. This case study compared the capture rates of all species, Swainson’s Thrush (Catharus ustulatus), Bewick’s Wren (Thryomanes bewickii) and Spotted Towhee (Pipilo maculatus) between the untreated and treated areas before and after restoration, and the overall capture rates from before restoration to after restoration. All species were positively affected by restoration, while Swainson’s Thrushes were negatively affected. Bewick’s Wrens and Spotted Towhees did not appear to be affected by restoration, but with further study it may be found that they will benefit from restoration.
