CEGL004017 Ceratophyllum demersum Western Aquatic Vegetation

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Coon''s-tail Western Aquatic Vegetation

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: Habitat is low-elevation, low-gradient, eutrophic streams and rivers, ponds, lakes, and sloughs. This is a non-rooted aquatic association that is widespread in western Oregon, but it has not been sampled and little information is available. Ceratophyllum demersum forms dense, monotypic submerged beds that do not emerge above the surface of the water. Eutrophic conditions favored by this association may be enhanced by enriched runoff in agricultural or urban landscapes. Though a native species, Ceratophyllum demersum is a well-known pest in many lakes where rank aquatic vegetation interferes with recreation.
