Abstract

We studied wintering owl use of hybrid poplar plantations, cropland, and shrub-steppe in northeastern Oregon. Logistic regression was used to identify habitat variables that best predicted owl presence or absence. We made 75 observations of 6 owl species during 2 y. The logistic regression model included the interiors of 5- and 6-y-old plantations as the best predictors of owl presence. Shrub-steppe habitat was included as the best predictor of owl absence. Significantly more owls were detected in 1999 compared to 2000. Maintaining an older component of interior plantation habitat within a plantation complex will likely create suitable wintering habitat for the owl species we studied.
