Focus Species Forestry - Maine Audubon

6. Focus Species Profiles and Management
Recommendations
The following pages include range, habitat, and management information for each focus species.
Following is a guide to interpreting and using the management profiles.
Maine Focus Region: Because species vary in their
abundance across the state, some species are not
focus species for the entire state. Figure 1 shows
Maine’s focus species habitat regions. The North
Region largely corresponds with the area where
extensive spruce-fir forests are found. The South
Region is associated with the approximate northern
and eastern limit of red oak as a significant forest
component (Allen and Plantinga 1999) and by the
southern limit of American marten.

Home Range: Home range is the area typically used
by an animal over the course of a year. In cases where
males and females have different home ranges, the
larger value is given. Home ranges between individual
animals often overlap. At the landscape or regional
level a viable population may require the area
equivalent to many home ranges.
Territory: Territory refers to the area that a pair of
songbirds actively defends during the nesting season.
While the area defended by a single pair of birds may
be very small, the species may most likely to be found
in large forest patches. For example, the wood thrush
has a territory ranging from 0.2-7 acres, but data from
the northern forest region show that it is most
abundant in forest patches that exceed 200 acres.
Management: This section includes specific management recommendations for each focus
species. These recommendations should be used in conjunction with the management
recommendations in the habitat management guides and the guides to stand and landscape-scale
management (Sections 7 and 8).
