CEGL004527 Brasenia schreberi Eastern Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Watershield Eastern Aquatic Vegetation
Colloquial Name: Eastern Watershield Pond
Hierarchy Level: Association
Type Concept: This community is found throughout the southeastern United States, from Georgia to Texas and in the interior to Kentucky, Oklahoma, and Arkansas. This vegetation occurs in a range of natural ponds and impoundments, including ponds, beaver ponds, and lake margins. Brasenia schreberi is the dominant plant species; other species may include Leersia oryzoides, Lemna valdiviana, Juncus effusus, Stuckenia pectinata, Nymphaea odorata, and Spirodela polyrrhiza. An occurrence along the Texas coast at McFaddin National Wildlife Refuge occupies the "open water" areas interspersed with emergent vegetation and "flotant" marsh dominated by Panicum hemitomon (~Panicum hemitomon Marsh (CEGL004665)$$). Other floating aquatics present include Nelumbo lutea, Nymphaea odorata, Nymphaea mexicana, and Utricularia spp., along with submersed aquatics such as Cabomba caroliniana and Ceratophyllum demersum and rooted aquatics such as Pontederia cordata and Zizaniopsis miliacea. Additional information is needed on the full range and variability of expression of this vegetation.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Known from artificial impoundments on the Ozark National Forest (Bayou District). An apparently disjunct example from the Interior Low Plateau is known from Kentucky''s "Hundred Acre Pond," a Karst sinkhole wetland. Brasenia schreberi is the dominant floating aquatic in the "open water" areas of Willow Slough Marsh (approx. 1000 acres) at McFaddin National Wildlife Refuge, Texas. Reported from South Carolina by Aulbach-Smith (pers. comm. 2001).

Floristics: Brasenia schreberi, a floating aquatic native to Florida that has become naturalized throughout much of the eastern and western U.S. and Canada, is the dominant plant species; other species may include Leersia oryzoides, Lemna valdiviana, Juncus effusus, Stuckenia pectinata (= Potamogeton pectinatus), Nymphaea odorata, and Spirodela polyrrhiza. Other floating aquatics present include Nelumbo lutea, Nymphaea odorata, Nymphaea mexicana, and Utricularia spp., along with submersed aquatics such as Cabomba caroliniana and Ceratophyllum demersum and rooted aquatics such as Pontederia cordata and Zizaniopsis miliacea.
