REVEGETATION PLAN
a sensitive plant species within the project vicinity, which occurs in a plant buffer of Segment
B near station 105+50 (CH2M Hill 2014). This occurrence of long-bearded hawkweed
(Hieracium longiberbe) is not expected to be affected. Although there are no known plants of
concern within the area to be directly affected there are additional areas of potential habitat
for long bearded hawkweed and Columbia kittentails (Synthyris missurica ssp. stellata). If RST
Restoration Specialists observe a species of concern they will salvage plants and care for them
ex situ at Dorena Genetic Resource Center, a USFS plant center in Cottage Grove, Oregon, or
adjacent to the affected area in similar habitat (on or near the project site). The plants would
then be resituated in their original location, or the nearest suitable location if the original is no
longer available, once the potential for disturbance has passed.
Wyeth Trailhead and Parking Lot
The planned parking lot at the Wyeth Trailhead incorporates a number of planting locations
that encompass approximately one acre in area, including a drainage catch basin in the center
and nine to twelve distinct planting pockets integrated into the outer curb. This area, more so
than any other along the project, is designed with an eye toward more traditional landscape
and horticultural practices. RST will work closely with Walker Macy to maintain public safety
and line-of-sight while creating multi-seasonal interest.
RST will conduct weed control throughout the area prior to planting, especially near the
entrance. There is currently a robust population of Scotch broom growing along Wyeth Road
and continuing beyond the ownership boundary to the west. Although it would be ideal to
treat the larger surrounding area (approximately four acres) to reduce future Scotch broom
re-establishment, funding for this work is not currently available. Therefore, only the area
referenced on the project plan sheets will receive treatment; less than one tenth of an acre.
Once treated, the open area on the west side of the trailhead entrance will be planted with
species that support pollinator-plant interactions (Table 1a). Efforts will be made to maintain
visuals of the trailhead sign and entrance while blocking the view of the new vault toilet
facility from the traveling public on Wyeth Road.
Contracting responsibility will be coordinated between WFLHD and RST. WFLHD will place 18”
of weed-free topsoil or borrow material into all planting areas other than the planting pockets.
The RST contactor will be responsible for providing weed-free topsoil to be combined with
compost for use in the planting pockets and the two large planting beds on either side of the
parking lot entrance. WFLHD will remove the non-native black locust trees currently on site.
