Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Bog Birch - Poison-sumac - Shrubby-cinquefoil Fen

Colloquial Name: Rich Shrub Carr

Hierarchy Level:  Association

Type Concept: This shrub fen association is characterized by a dense mixture of shrubs 1.5-2 m tall in deep muck, often in standing water 15 cm (6 inches) or more deep, in limestone regions of Lower New England / Northern Piedmont. It receives regular inundation and surface flooding. This association is most typically found on lakeshores but may also be found at streamsides. Characteristic shrubs are Betula pumila, Salix candida, Toxicodendron vernix, Rosa palustris, Alnus incana, Alnus serrulata, Viburnum dentatum, Viburnum nudum, Viburnum lentago, Viburnum opulus var. americanum, as well as Dasiphora fruticosa ssp. floribunda, which reaches 1 m in height. Herbaceous associates are few and sparsely distributed, and include Galium trifidum, Carex stricta, Carex lacustris, Calamagrostis canadensis, Campanula aparinoides, and Lysimachia thyrsiflora. Scattered individuals of Acer rubrum saplings are also typical.
