The
Gifford Pinchot National Forest proposes to reduce the risk (threat) of
large stand-replacing fire through preventive strategies. The area affected
by the proposal includes a 19,700-acre portion of the Gifford Pinchot National
Forest, known as the Gotchen Planning Area, which includes the Gotchen
Late Successional Reserve (LSR) and Matrix lands to the south and east
of the LSR.
This area is located on the east slopes of the Cascade Range,
within the White Salmon Watershed, south of Mt. Adams and east
of the White Salmon River. The action is needed, because of the present
risk of losing
late-successional function from large-scale ecological disturbances
(ongoing defoliation caused by insect and disease activity), and the threat
of losing
habitat from large, stand-replacing fires.
Forest management actions over the past century, including wildfire suppression
and selective logging, have dramatically changed the forested landscape
from its historical condition, or reference condition to a landscape dominated
by dense, multi-layered stands and concentrations of down wood material.
Defoliation from elevated insect and disease activity is impacting late
successional habitat in two primary ways. First, the budworm defoliation
and resultant tree mortality is affecting fuel loading. Second, within
the Gotchen Planning Area approximately 76% of the forest currently provides
suitable habitat for the northern spotted owl. The decline and loss of
suitable habitat is directly affecting owl populations within the LSR.
It is an indication that the late-successional forest stands within the
Gotchen area have lost desired function as habitat for other late-successional
dependent species.
These issues led the agency to develop alternatives to the proposed
action including:
- Alternative A – No Action
- Alternative B – Shaded fuelbreaks are the centerpiece
of this alternative. Risk reduction treatments would be implemented across
1,684 acres, including 1,139 acres within the LSR. Shaded fuelbreaks are
strategically located along existing roads to “compartmentalize” large
blocks of forest that have heavy fuel loads. Additional stands
that complement the Shaded Fuelbreaks are treated to reduce stand densities
and fuel loads
to break up the continuity and arrangement of the stands and
fuel beds. In general, the Proposed Action takes a somewhat conservative
approach
in reducing the understory grand fir within the areas in the
LSR hardest-hit by the spruce budworm. This alternative includes 7.5
miles of temporary
road construction or reconstruction.
- Alternative C - (The Preferred Alternative)
- The emphasis of this alternative is to reduce fire risk and improve
late-successional function and resiliency by
directly
treating fuels and reducing understory density in high-risk areas.
This alternative treats a total of 2,220 acres, of which 1,701
acres are within
the LSR and 98 acres are within riparian habitat. From a fuels-management
perspective, this alternative utilizes a more “traditionalist” approach
by directly modifying vegetation and fuel profiles in areas of
high fire hazard and high stand densities. Alternative C includes
4.3 miles of temporary
road construction or reconstruction.
- Alternative D – This alternative emphasizes treatment of ground
and ladder fuels to minimize the spread of fire by treating a total of 1,645
acres, 1,100 within the LSR. Impacts to suitable owl habitat are minimized
by restricting live tree removal within proposed fuelbreaks to 10” dbh,
or less thereby maintaining overstory canopy cover near current levels.
Treatment within riparian habitat is limited to removal of hazard-prone
trees less than 6” dbh. Alternative D includes 4.1 miles of temporary
road construction or reconstruction.
All action alternatives include 24.8 miles of road closure or decommissioning
within the LSR and Matrix. Specifically, the road management proposals
would reduce road density, decrease maintenance costs, reduce impacts
to water
quality, minimize conflicts with wildlife, and reduce vehicular
access to roads not essential for fire suppression.
In addition, all of the action alternatives include a 10-acre quaking
aspen restoration project at Gotchen Creek Guard Station. Quaking
aspen historically occupied more of this landscape, but have
been out-competed by conifers.
Based upon the effects of the alternatives, the responsible official will
decide:
- Whether or not to remove the dead and dying timber from the
Gotchen Matrix
- Whether or not to implement risk-reduction activities within the
Gotchen LSR
-
Whether or not to implement road-related actions—decommissioning,
or closing
- Whether or not to implement the quaking aspen restoration project
If the District Ranger decides to implement any of the above, the
decisions on the activity type, location, priority, timing and
sequencing will be made and documented in the Record of Decision (ROD).
