However, there is no reason that <br /> native grasses and forbs can provide the same functions. The species <br /> recommended here are either 1) woody plants that root readily from <br /> hardwood cuttings, or 2) herbaceous plants that appear to have characteristics <br /> of rapid germination and initiation of vegetative growth, and /or formation of <br /> a fibrous root system to bind soil. They are mostly species of upland <br /> habitats. Both annuals and perennials are included; the inclusion of some <br /> short-lived species is considered appropriate for this situation. Consideration <br /> should be given to providing for appropriate ratios of grasses to legumes and <br /> other forbs. <br /> Wetland <br /> Scientific Name Common Name Indicator Status` <br /> TREES <br /> Populus trichocarpa black cottonwood FAC <br /> Salix lasiandra Pacific willow FACW + <br /> Salix piperi Piper's willow FACW <br /> Salix scouleriana - Scouler's willow FAC <br /> • <br /> SHRUBS AND VINES <br /> Cornus stolonifera var. occidentalis red -osier dogwood FACW <br /> Physocarpus capitatus Pacific ninebark FAC + <br /> Salix sessilifolia soft - leaved willow <br /> 6 <br />
