Sustaining forest habitat for the northern goshawk: a question of scale--Abstract
Russel T Graham, Richard T Reynolds, M Hildegard Reiser, Richard L Bassett, and Douglas A Boyce

The nest area, post-fledgling family area, and foraging area are critical home range components for maintaining northern goshawk (Accipiter gentilis) populations. Each of these forest components has a specific purpose in the life history of the northern goshawk and each contains several important attributes, ranging from forest structure to forest floor characteristics. The way in which home range components in a forest regenerate, develop, and die is highly variable, both temporally and spatially. Therefore, forests need to be regenerated and tended to ensure that a portion of a goshawk's home range is n old forests indefinitely. This can be best accomplished by analyzing and managing large tracts of forests as sustainable ecological units rather than managing smaller tracts of forests as individual home ranges.
