Name: Polygonum spp. - Mixed Forbs Herbaceous Vegetation
Reference: Midwestern Ecology Working Group...
Description: This ephemeral pond community type occurs widely throughout the midwestern region of the United States. Stands occur in shallow depressions that may flood for several weeks in the spring, but draw down by early summer. These basins may be kettles in glacial deposits, low spots in outwash plains, or depressions in floodplains. A wide variety of forbs and graminoids may colonize the exposed substrate. Species include <i>Bidens</i> spp., <i>Cyperus</i> spp., <i>Echinochloa crus-galli</i>, and <i>Polygonum</i> spp. In Missouri <i>Polygonum hydropiperoides</i> is common. In sand ponds in central Illinois, annuals were the most common species, including some of the major dominants, such as <i>Schoenoplectus hallii (= Scirpus hallii), Ammannia coccinea</i>, and various <i>Polygonum</i> spp. (including <i>Polygonum hydropiperoides, Polygonum lapathifolium, Polygonum pensylvanicum</i>, and <i>Polygonum persicaria</i>). Dominant perennials include <i>Typha latifolia, Typha angustifolia, Schoenoplectus tabernaemontani (= Scirpus tabernaemontani)</i>, and <i>Polygonum amphibium</i>). Rare species found in these sand ponds include <i>Boltonia decurrens</i> and <i>Schoenoplectus hallii (= Scirpus hallii)</i>. These ponds are of high importance to certain amphibians and invertebrates.
