The wetland is classified by vegetation as a shrub and forested wetland. The wetland tree canopy is dominated by western red cedar, red alder and Pacific willow. The wetland shrub layer contains salmonberry, vine maple, hardhack and willow saplings. The herbaceous (non-woody) plant community consists of reed canarygrass, slough sedge, water parsley, and lady fern. Upland vegetation adjacent to the wetland consists of Douglas fir, western hemlock, western red cedar, vine maple, salal, dull Oregon grape, trailing blackberry, sword fern, and deer fern. Invasive species in this upland forest include some areas of Himalayan blackberry, ivy, holly, and yellow archangel. There are also bare soil areas that occur over much of the upland area due to pedestrian use and disturbance and opportunities exist for vegetation enhancement and restoration.
