Name: Populus fremontii - Salix laevigata Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This riparian woodland is known from northern, central, and southern California, from the Sierra Nevada foothills, central interior Coast Ranges, and San Diego and Riverside counties. It occurs on low-gradient, relatively wide or narrow streams and rivers at elevations from 57 to 1275 m (187-4182 feet). Stream gradients range from 0-4°. Valley width is usually moderately wide to wide, with a few occurrences on narrow reaches. <i>Populus fremontii</i> and <i>Salix laevigata</i> are typically codominant, although some stands lack red willow. Tree cover typically exceeds 50% (4-90%), but some stands have much less cover. Conversely, understory layers are usually open. Shrub species that may be present include <i>Baccharis salicifolia, Baccharis pilularis, Salix lasiolepis, Rubus armeniacus, Rubus ursinus</i>, and <i>Rosa californica</i>. The herbaceous cover is also highly variable. No understory species is designated in the name of this association to reflect the high variation and lack of consistency of the understory layers.
