A2628 Fontinalis antipyretica Aquatic Vegetation Alliance
Type Concept Sentence: This alliance consists of submerged aquatic herbaceous communities dominated by nonvascular Fontinalis antipyretica. These stands occur in seasonally or perennial flooded pools, ponds and sloughs of the northwestern U.S. and western Canada.
Common (Translated Scientific) Name: Aquatic Moss Aquatic Vegetation Alliance
Colloquial Name: Pacific Northwest Aquatic Moss Aquatic Vegetation
Hierarchy Level: Alliance
Type Concept: This alliance consists of submerged aquatic herbaceous communities dominated by nonvascular plant Fontinalis antipyretica which forms extensive submerged beds in seasonally or perennial flooded pools, ponds and sloughs. It is found throughout the northwestern U.S. and western Canada.
Diagnostic Characteristics: Submerged or exposed beds of Fontinalis antipyretica.

Floristics: This alliance consists of submerged aquatic herbaceous communities dominated by nonvascular plant Fontinalis antipyretica and other Fontinalis spp. which form extensive submerged beds.
Dynamics: Fontinalis antipyretica is tolerant of wet and dry periods. Beds may be up to 1 m (2-3 feet) thick while submerged and condense to 15 cm (6 inches) when dry.
Environmental Description: These stands occur in seasonally or perennial flooded pools, ponds and sloughs. Stands tolerate wetting/submergence as well as seasonal exposure to air. Beds may be up to 1 m (2-3 feet) thick while submerged and condense to 15 cm (6 inches) when dry. They occur in cold, clean freshwater and do not seem to increase under eutrophic conditions (Christy 2004).
Geographic Range: This alliance is widespread in northwestern Oregon and in Washington, where it is common west of the Cascade Range. It is also known from western Canada.
Nations: CA,US
