Thus the strict separation of forested
landscapes into old-growth and regrowth forests (Fig. 2) may not
represent an optimal species conservation strategy with regard to
the provision of habitats in the landscape. Instead, it may be better
to manage forests for conservation based on their degree of oldgrowthness,
their local and landscape functions in recognition of
the expected opportunities for, and constraints to obtaining
desirable levels of old-growthness. However, practically, it could
be extremely difficult and costly to evaluate and assign a specific
