One of the project goals is to increase the diversity of the native plant community on the site. Currently the site is dominated by invasive reed canarygrass. The project includes planting a variety of native species such as red osier dogwood, native willows, spruce, Douglas-fir, black cottonwood, and native shrubs such as snowberry, currants, chokecherry, and elderberry.

These planting plots may someday provide willow and red osier dogwood for beaver, and spruce that can fall into the stream to improve structure and habitat in the channel.

Planting Plots in the Triple Creek Riparian Buffer Zone
Ten planting plots on the upper floodplain (shown above in white and yellow) are being intensively managed for weed control and planted with native species appropriate for the drier soil hydrology. In addition, terraces, or inset floodplains within the incised channel (shown in green above) are being planted with native riparian species suited for the wetter soil conditions.

 This riparian planting plot includes plants that tolerate a variety of hydrologic conditions, and the reed canarygrass and thistle are smothered with cardboard and bark.
