CEGL005193 Thuja occidentalis - (Myrica gale) / Trichophorum alpinum / Drepanocladus spp. Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Northern White-cedar - (Sweetgale) / Alpine Bulrush / Brown Moss species Fen
Colloquial Name: Northern White-cedar - Sweetgale Scrub Fen
Hierarchy Level: Association
Type Concept: This white-cedar scrub fen type is found in southern Ontario, Canada, and possibly in adjacent northern areas of the Great Lakes states in the United States. Stands contain at least 40 cm or more of brown moss or sedge peat. Stands are rarely flooded, primarily saturated, and the pH is slightly alkaline to mildly acidic. The vegetation contains a scrub layer between 1 and 2 m tall dominated by Thuja occidentalis, with occasional Myrica gale. The ground layer contains a rich diversity of herbs and mosses, including Trichophorum alpinum and Drepanocladus spp.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Type concept is taken from the southern Ontario list of vegetation types by Lee et al. (1998) and needs rangewide review. Type may closely resemble a Dasiphora fruticosa ssp. floribunda shrub fen type, ~Dasiphora fruticosa / Carex interior - Carex flava - Sarracenia purpurea Fen (CEGL005140)$$. Trichophorum alpinum is the Kartesz (1999) name for Scirpus hudsonianus. See also ~Betula pumila - Dasiphora fruticosa / Carex lasiocarpa - Trichophorum alpinum Fen (CEGL002495)$$ for a similar, but more boreal, rich fen.
