A3825 Alnus incana ssp. tenuifolia - Salix pulchra / Carex aquatilis Shrub Swamp Alliance
Type Concept Sentence: This alliance covers herbaceous wetlands with open or patchy shrub cover (up to 25% cover); shrub species include Myrica gale, Alnus incana ssp. tenuifolia, or Salix spp. and is limited to boreal and boreal transition climates.
Common (Translated Scientific) Name: Thinleaf Alder - Tealeaf Willow / Water Sedge Shrub Swamp Alliance
Colloquial Name: Western Boreal Alder - Willow Shrub Swamp
Hierarchy Level: Alliance
Type Concept: These are herbaceous wetlands with an open shrub canopy (10-25% cover) found on mostly seasonally saturated mineral soils in boreal and boreal transition climates. The shrubs tend to be low-statured. The herbaceous cover is high (>60%).
Diagnostic Characteristics: Boreal and boreal transition low-statured open or patchy shrubs with 10-25% cover over very dense herbaceous growth in saturated soils.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Open (10-25% cover) shrublands intermixed with dense herbaceous cover wetlands, may be splitting hairs with herbaceous alliance with a few shrubs (those with <10% cover).
