Name: Carex unilateralis - Hordeum brachyantherum Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This graminoid wetland association is the only grass-sedge wetland type in the Oregon interior valleys. It is dominated by Hordeum brachyantherum with 10-20% cover, and Carex species with 30-80% cover. Carex unilateralis is always present with cover varying from 2-60%. Other common Carex species include Carex obnupta, Carex lasiocarpa, Carex utriculata, and Carex pellita. Juncus species are also commonly present and include Juncus balticus, Juncus acuminatus, Juncus oxymeris, and Juncus tenuis. Deschampsia caespitosa is occasionally present, but never dominant. Forbs include Mentha arvensis, Prunella vulgaris, Veronica spp., and Ranunculus spp. Rosa gymnocarpa, Spiraea douglasii, Crataegus douglasii, and Salix sitchensis occasionally occur as patches in this association. With fire suppression, Fraxinus latifolia is a common native invader. In the winter and spring this association is under >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: VB.CC.22938.CAREXUNILATERAL Plot-observations of this Community Concept: 0
