The northern goshawk (Accipiter gentilis, hereafter goshawk) is widely recognized as a species sensitive to forest development. Forest development activities that affect the nest area represent the most direct potential impact to goshawks because: 1) of the critical importance of the nest area for reproduction of the species, 2) the relatively small size of the nest area (~24 ha) makes it susceptible to being completely removed by a cutblock, 3) goshawks exhibit very strong site fidelity to nest areas, often using them for periods of years or decades, and it is unknown how successfully they can establish a new nest area once an original one becomes unavailable, and 4) there is high overlap with suitable nest area habitat and the Timber Harvesting Land Base .
