CEGL001984 Ranunculus aquatilis - Callitriche palustris Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Whitewater Crowfoot - Vernal Water-starwort Aquatic Vegetation
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is widespread and found in natural ponds, stockponds, ditches and slow-moving streams. The water on these sites is often poorly oxygenated and nitrogen-rich. Water depths average 30-60 cm deep. Soils are organic oozes (sapric histosols), organic rich loams, sandy loams or sands. Mean total cover is 88%, ranging from 39-130%. This is a low-diversity association, with mean richness at 7.4, ranging from 5-9. The Ranunculus plants are mostly submerged with only the uppermost leaves and stems touching the water surface, and thus are only observed when looking directly into the pond water. The small white flowers, however, float on the water''s surface and are quite distinctive. Common forbs include Ranunculus aquatilis, Potamogeton natans, Callitriche palustris, and Ranunculus flammula. Common graminoids are Carex utriculata, Eleocharis palustris, and Torreyochloa pallida var. pauciflora.
