Name: Carex unilateralis - Hordeum brachyantherum Wet Prairie Reference: NatureServe Biotics 2019 Description: This graminoid wetland association is the only grass-sedge wetland type in the Oregon interior valleys. It is dominated by <i>Hordeum brachyantherum</i> with 10-20% cover, and <i>Carex</i> species with 30-80% cover. <i>Carex unilateralis</i> is always present with cover varying from 2-60%. Other common <i>Carex</i> species include <i>Carex obnupta, Carex lasiocarpa, Carex utriculata</i>, and <i>Carex pellita</i>. <i>Juncus</i> species are also commonly present and include <i>Juncus arcticus ssp. littoralis, Juncus acuminatus, Juncus oxymeris</i>, and <i>Juncus tenuis</i>. <i>Deschampsia cespitosa</i> is occasionally present, but never dominant. Forbs include <i>Mentha arvensis, Prunella vulgaris, Veronica</i> spp., and <i>Ranunculus</i> spp. <i>Rosa gymnocarpa, Spiraea douglasii, Crataegus douglasii</i>, and <i>Salix sitchensis</i> occasionally occur as patches in this association. With fire suppression, <i>Fraxinus latifolia</i> is a common native invader. In the winter and spring this association is under &gt;10 cm of water, but it is usually dry for 3 months (July-September) each year. This association occurs on heavy clay valley deposits, often in old valley bottom river oxbows or bottomland swamp and lake remnants.  Accession Code: urn:lsid:vegbank.org:commConcept:30739-{8EEDB331-0713-4B81-8E94-7E333A571E21} Plot-observations of this Community Concept: 0
