CEGL003387 Salix hookeriana - (Salix sitchensis) Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Dune Willow - (Sitka Willow) Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: According to Christy (2004), this association occurs in depressions in floodplains and potholes in basalt scablands of western Oregon and Washington. The association is undersampled, but it is common and widespread in the Willamette Valley, along the Columbia River, and at lower elevations in the Cascade Range. It represents clonal shrub swamps of the inland morphotype of Salix hookeriana that was previously called Salix piperi. Shrub swamps of this species occur in two phases determined by composition of the herb layer. Stands are typically dense thickets and are either monotypes of Salix hookeriana or have admixtures of Salix sitchensis and/or Spiraea douglasii. In two plots from northwestern Oregon, Salix hookeriana has an average cover of 78% and ranging from 65-90%. Densely branched adventitious roots on the lower stems of Salix hookeriana and large whitish mats of dried algae may remain draped like tents over roots and trunks after water levels recede. Fontinalis antipyretica and Dichelyma uncinatum are conspicuous in the moss layer.
