CEGL001155 Alnus viridis ssp. sinuata / Acer circinatum Shrub Swamp
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sitka Alder / Vine Maple Shrub Swamp
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs at middle elevations in the Cascade Range and Olympic Mountains. Sites are usually moderate to steep slopes (34-85%) on talus or avalanche chutes. The well-developed, tall-shrub layer is codominated by Alnus viridis ssp. sinuata and Acer circinatum. The understory layer frequently includes Maianthemum stellatum and Cryptogramma acrostichoides. The shrubs Paxistima myrsinites and Rubus parviflorus and the forb Maianthemum racemosum are infrequent but prominent. Moss and lichen ground cover may be prominent.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This Cascadian association is similar to ~Alnus viridis ssp. sinuata / Mesic Forbs Wet Shrubland (CEGL002633)$$, except for the codominance of Acer circinatum. The latter association includes Acer circinatum-codominated stands and fails to recognize biogeographic variation.
