Refer to The Forest Plan and the Broadscale analysis for the Example Landscape for details.
Summarized Objectives:
1. Winter game range - manage for effective cover/forage (25% of this landscape, including these stands).
2. Visual Quality Objective - modification for ground viewers.
3. Provide for a diversity of composition, and structure of the forest community, including old growth structures and amounts, within the the Landtype Associations in
the landscape to provide for long term ecosystem function. The late seral stage structures should occupy
15-20% of the landscape.
4. Regulate timber yields commensurate with winter game range and old growth structure requirements.

Cover|
SPECIES)
At stand rotation age, the desired attributes would include: An open
park-like old growth structure with reserve trees from an older
cohort. The stand would be primarily even-aged, single storied,
mixed species stand the majority of which consists of seral species.
Composition would be 60% PP (with remainder a majority of DF, with
minor components of ASP) maintained in a vigorous condition with
limited I&D concerns. A veteran component of 250 year or older PP
and/or DF with diameters exceeding 16 inches DBH would be included in
the primary stand structure (maintained at 60-100 sq. ft. of basal
area during the second half of the rotation period). Aspen would
be another component of the stand occupying from 5% to 10% of the
area. Stand size should be between 25 to 150 acres+. Down woody
4"+ objective would be approximately 5-15 ton/ac.,unevenly distributed.
Cavity nester habitat maintained at greater than 70% of optimum.
Grass and forb composition shall be maintained at capability levels
considering the density of the tree overwood. This form of old
growth structure would provide habitat needs for species such as
flamulated owl, that prefer open park-like conditions for feeding
habitat. A rotation age of approximately 250 years would yield 25
cu. ft. per acre per year.
Over the landscape as a whole: maintain 50% of the winter range area
in thermal cover and 30% of the area in security cover. VQO shall be
met via shape of the stand fitting natural topography, irregular edges,
remaining residual trees, and timing of stand treatments within the
landscape.

No, current

Yes. Removal of the
DF understory will
restore the std to
a more open grown
old growth structure,
and will reduce SBW
levels and high fuel
levels in these stds.
Basal area of approx
70-90 sq ft would
be retained and
would maintain
thermal cover
value.
The alternative of
thinning from below
is recommended as it
will contribute to
the DFC on the
greatest number of
acres while
maintaining future
options in these stds.

|
Yes. Group selection in these stds
would develop an acceptable stand
It will maintain a multi storied std
with old growth structure. This
structure will benefit old growth
dependent species requiring dense
interior multi story structure.
This stand structure should be
limited in scope within the
landscape to keep western spruce
budworm at relatively low levels,as
a higher % of DF will result with
this method overtime. Thermal cover
will be more difficult to attain
with this structure. A differnt
desired stand condition (DSC)
would develop with this approach.
