Name: Picea sitchensis - Tsuga heterophylla / Oplopanax horridus / Athyrium filix-femina Riparian Forest
Reference: NatureServe Biotics 2019
Description: This riparian forest of Alaska and British Columbia is dominated by large <i>Picea sitchensis</i> surrounded by <i>Oplopanax horridus</i>. Mature <i>Tsuga heterophylla</i> trees occur in 50% of the stands. The trees tend to be taller on uplifted beach ridges and shorter on other landscapes. <i>Oplopanax horridus</i> dominates the understory with scattered amounts of <i>Vaccinium</i> species and <i>Rubus spectabilis</i> occurring in many stands. <i>Oplopanax horridus</i> and <i>Rubus spectabilis</i> cover increases in tree canopy gaps. <i>Rubus pedatus</i> and <i>Tiarella trifoliata</i> are common forbs. <i>Dryopteris expansa</i> and <i>Gymnocarpium dryopteris</i> are common ferns. This community type is found primarily on well-drained sand or gravel on uplifted beach ridges, floodplains, moraines, and proximal outwash. The water table occasionally rises into the surface horizons in the floodplain stands, whereas in most other stands, the water table is typically 1 m (3 feet) or more below the surface. The soils are usually classified as Oxyaquic Haplocryods in the floodplains and as Typic Haplocryods in the other landscapes.
