Management recommendations for the northern goshawk in the southwestern United States
Οι σημερινές συνθήκες των δασών - απώλεια ποώδους και θαμνώδους υπορόφου, μειώσεις των εκτάσεων γηραιότερων δασών και αύξηση εκτάσεων δασικής αναγέννησης υψηλής πυκνότητας - αντικατοπτρίζουν την έκταση της ανθρώπινης επιρροής στα δάση αυτά. Αυτές οι αλλαγές μπορεί επίσης να επηρεάσουν τους πληθυσμούς Διπλοσαΐνων. . Information on goshawk nesting habitat and foraging behavior, and the food and habitats of selected goshawk prey, was therefore synthesized to develop a set of management objectives, desired forest conditions, and management recommendations. Key objectives of the guidelines are to provide (1) nesting, post-fledging, and foraging areas for goshawks, and (2) habitat to support abundant populations of 14 primary goshawk prey. Thinning trees in the understory, creating small openings in the forest, and prescribed fires should help produce and maintain the desired forest conditions. Other habitat elements critical for maintaining both goshawk and prey populations include abundant snags and large downed logs, woody debris, interspersion of different tree sizes across the landscape, and the majority of a goshawk’s home range in older-aged forests. These guidelines should also benefit forest health, soil productivity, and the habitats of other old-growthdependent plants and animals.
