Name: Alnus rubra / Athyrium filix-femina - Asarum caudatum Swamp Forest
Reference: NatureServe Biotics 2019
Description: Found only along two streams on the northwestern slope of the Blue Mountains of Oregon and Washington and reported in another drainage in the Clearwater Mountains of Idaho, this riparian forest community typically appears on streamsides and wet seeps in the grand fir zone. Elevations range from 610 to 1070 m (2000-3500 feet). This riparian association is dominated by <i>Alnus rubra</i>, typically the sole tree species in a closed canopy. <i>Abies grandis</i> or <i>Pseudotsuga menziesii</i> dominate the forests on adjacent uplands. This association is floristically diverse and characterized by high cover of <i>Athyrium filix-femina</i> plus other moist sites species, such as <i>Asarum caudatum, Glyceria striata, Tiarella trifoliata var. unifoliata</i>, and <i>Carex deweyana</i>. It may have a tall deciduous shrub layer dominated by <i>Physocarpus capitatus</i> and/or <i>Cornus sericea</i>.
