Common (Translated Scientific) Name: Gray Alder / (Water Sedge, Lakeshore Sedge, Woodrush Sedge, Woolly Sedge) Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is currently only described from Oregon but is also reported to occur in Montana, Washington, and possibly Idaho. Additional global information will be added as it becomes available. Sites were sampled in the Blue Mountains and East Cascades ecoregions at moderately low to moderately high elevations Valleys in which this association occurs are low gradient, V- or trough-shaped, narrow to wide with gentle to moderately steep sideslopes. Associated Rosgen stream types are 0.5 to 10 m wide E5 and B streams with little organic debris affecting the active stream channel. Soils comprise deep, fine-textured mineral material with seasonally high water tables that probably drop to below the Carex pellita rooting zone by the end of the growing season. Alnus incana forms a scattered to dense canopy averaging 5 m in height. Carex pellita abundance varies inversely with Alnus incana canopy cover as it is somewhat shade-intolerant. Other species commonly scattered throughout the herbaceous layer are Juncus arcticus ssp. littoralis, Carex microptera, Geum macrophyllum, and Equisetum arvense. Herbaceous species average 46 cm (ranging from 31 to 61 cm). Biomass averages 2770 lbs/acre.
