Name: Salix hookeriana - (Malus fusca) / Carex obnupta - Lysichiton americanus Wet Shrubland
Reference: NatureServe Biotics 2019
Description: This association occurs along the coast between northern California and southern British Columbia. It is an early- to mid-seral association that occurs on perennially wet mucky soils with high organic content, usually adjacent to lakes and ponds, on old deflation plains, and interspersed with open mire in peatlands. Sites may be flooded seasonally or year-round, but water is usually just below the soil surface in summer. Water levels must be relatively constant to maintain hydrology. The tree layer is sparse in most stands, with a few scattered <i>Alnus rubra, Pinus contorta</i>, or <i>Picea sitchensis</i> growing on low hummocks or around the margin of the wetland. A dense, tangled layer of tall shrubs dominated by <i>Salix hookeriana</i> and/or <i>Malus fusca</i> forms a canopy ranging from 30-95% cover. <i>Spiraea douglasii</i> typically forms a lower shrub layer on wet soils, especially in gaps in the canopy of tall shrubs. <i>Gaultheria shallon</i> and <i>Lonicera involucrata</i> may occur on hummocks. The ground layer is dominated by <i>Carex obnupta</i> and <i>Lysichiton americanus</i>, with expanses of deep muck soil exposed in the most shaded places. Epiphytic mosses and <i>Polypodium glycyrrhiza</i> are abundant in the canopy of tall shrubs. The moss layer contains mostly <i>Eurhynchium praelongum</i>, but one site is habitat for the rare moss <i>Limbella fryei</i>. <i>Sphagnum</i> occurs in this association along the northern coast of Oregon in Clatsop County, and occurs in similar sites farther north. Stands appear to be long-lived, maintained by wet soils and gap succession. The willows sustain frequent crown damage from winter storms and heavy browsing by beavers, followed by vigorous sprouting.
