Abstract
Conservation of old stands of Canada's boreal forest is critical for forest biodiversity, and strategies for achieving regional old forest targets include reduced harvest rates, extended rotations, and reserves. Structural retention can help conserve old forest species in aggregated harvests, but models indicate that over the long-term and at large spatial scales structural retention is insufficient on its own. To benefit most cavity excavators, 20% of the total aggregated harvest area should be retained in patches of mature and old trees. Old forest cavity excavators use a variety of foraging substrates, and fine-filter management of old forest cavity users in aggregated harvests depends on retaining the types of trees and patches used for nesting and foraging.
