Abstract

As part of forest resource monitoring efforts in Sun Pass State Forest, we conducted surveys for White-headed Woodpeckers (Picoides albolarvatus) during May and June 2007. We conducted surveys using call points along a standardized grid. We had 70 White-headed Woodpecker detections in the forest boundary. We found 2 nest sites in 17- and 20-cm diameter Quaking Aspen (Populus tremuloides) trees. Sun Pass was characterized primarily by early to mid-seral Ponderosa Pine (Pinus ponderosa) and Ponderosa Pine-dominated mixed-conifer forest stands managed primarily by single tree selection harvests. There is little published information on this species, and evidence suggests that this species is associated with old growth Ponderosa Pine habitat. Our results indicate that this species also uses an actively managed forest in the southeastern Oregon Cascade Range.
