The timing, magnitude, duration, and spatial distribution
of peak, high and low flows must be protected.
7. Maintain and restore the timing, variability, and
duration of floodplain inundation and water table
elevation in meadows and wetlands.
8. Maintain and restore the species composition and
structural diversity of plant communities in riparian areas
and wetlands to provide adequate summer and winter
thermal regulation, nutrient filtering, appropriate rates of
surface erosion, bank erosion, and channel migration and
to supply amounts and distributions of coarse woody
debris sufficient to sustain physical complexity and
stability.
9. Maintain and restore habitat to support well-distributed
populations of native plant, invertebrate, and vertebrate
riparian-dependent species.

channel and because of the small scale of the project, are
expected to occur for a very limited duration.
The removal of conifers could have a small effect on the
timing, variability, and duration of floodplain inundation
within the project area. It is also possible that the conifer
removal could have a more sustained effect on the
meadow hydrology by raising water table levels during
periods of runoff.
Removal of conifers will maintain the small meadow
habitats and stream-side riparian vegetation. Mature
willow provides abundant woody debris recruitment for
maintaining channel structure.
The proposed action will have a positive effect in
maintaining and restoring habitat to support populations of
native plant, invertebrate, and vertebrate ripariandependent
species.
Appropriate management activities for Riparian Reserves include those activities that
restore and preserve Riparian Reserves, are consistent with the Aquatic Conservation
Strategy and move the reserves towards a Desired Future Condition.
Plan and implement vegetation management activities that restore and/or preserve the
aquatic, riparian and meadow habitats unique to the McBride Springs landscape.
Manage Riparian Reserves to meet Aquatic Conservation Strategy Objectives and to
move Reserves towards desired future conditions. 8
No adjustments to the Riparian Reserve widths are recommended from this McBride
Springs PLWA.
To harvest the true fir hosts of the annosus disease, heavy equipment is required to
enter the riparian reserves at the McBride Springs Campground. To protect the
immediate floodplains and banks of the channels and springs, an Equipment Exclusion
Zone (EEZ) should be designated.
Twenty feet out from any spring, intermittent stream or ditch except for stream
crossings a 20 foot EEZ, measured from the channel banks outward on each side, will
be designed to avoid impacts to hydrologic and riparian vegetative features. 9
No ground disturbance within this zone should occur from equipment capable of
reaching in from outside the zone. Where this is not possible, as in the stream
crossings, minimal ground disturbance may occur within the EEZ where directional
hand-falling conifer requires the log to be dragged out by a grapple line attached to
heavy equipment such as a skidder.
