Northern goshawk (Accipiter gentilis)<br />

Environmental Baseline<br />

The goshawk is a forest hawk associated with late successional forest, or with mid-successional<br />

forests with late successional elements, in mixed conifer or true fir habitat types. Foraging<br />

habitat is variable <strong>and</strong> includes mid- <strong>and</strong> late-successional forest, natural <strong>and</strong> man-made<br />

openings, <strong>and</strong> forest edges. Moderate <strong>and</strong> high quality habitats contain abundant large snags <strong>and</strong><br />

large logs for prey habitat <strong>and</strong> plucking posts (Hall 1984). Goshawks generally breed in olderage<br />

coniferous, mixed <strong>and</strong> deciduous forest habitats. This habitat provides large trees for nesting,<br />

a closed canopy for protection <strong>and</strong> thermal cover, <strong>and</strong> open spaces allowing maneuverability<br />

below the canopy (Hall 1984). Forest st<strong>and</strong>s containing nests are often small, approximately 25-<br />

250 acres (Reynolds et al. 1982, Woodbridge <strong>and</strong> Detrich 1994); territories may contain 1–5<br />

alternative nest areas. In northern California, maximum distance between alternative nest st<strong>and</strong>s<br />

was about 1 mile, <strong>and</strong> approximately 85% of alternate nest st<strong>and</strong>s were
