Great Grey Owl - Habitat

Habitat

The harvest of timber from the Great Grey Owl's habitat is, perhaps, the greatest threat to this species. Intensified timber management typically reduces live and dead large-diameter trees used for nesting, leaning trees used by juveniles for roosting before they can fly, and dense canopy closures in stands used by juveniles for cover and protection. If perches are not left in clearcuts, Great Grey Owls cannot readily hunt in them. Although human-made structures (made specifically for use by this species) have been utilized by these owls, the species is far more common in areas protected from logging. Livestock grazing in meadows also adversely affects Great Grey Owls, by reducing habitat for preferred prey species.

Famous quotes containing the word habitat:

    Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.
    William James (1842–1910)

    Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.
    John Dewey (1859–1952)
