Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Cooley''s Hedge-nettle - Piggyback Plant Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This red alder forest of Washington, Oregon and possibly British Columbia has a canopy dominated by Alnus rubra. The understory is dominated by a diverse array of forbs such as Tolmiea menziesii, which can be dominant, Stachys chamissonis var. cooleyae, Tiarella trifoliata, and/or Claytonia sibirica. Athyrium filix-femina is usually present but rarely more than prominent. Urtica dioica can be very abundant. The shrubs Acer circinatum, Oplopanax horridus, or Rubus spectabilis are frequently encountered and typically sparse. This association occurs in the Olympic Mountains, Mount Rainier and likely elsewhere in western Washington at lower elevations on moist, well-drained soils that are located on riparian floodplains, streambanks or lower terraces. Sites are periodically flooded but with trees and other vegetation surviving. Most sites display evidence of recent flooding, such as mineral soil deposits and flood debris.
