CEGL003378 Calamagrostis nutkaensis - Carex spp. - Juncus spp. Grassland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Pacific Reedgrass - Sedge species - Rush species Grassland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: Stands are limited to within a few kilometers of the California coast. At Point Reyes National Seashore, this vegetation grows in seasonally saturated soils on gentle slopes of all aspects. Stands prefer seeps, basins, swales, and plains, which collect water during the rainy season. Soils are moderately coarse to fine sandy loams. Stands are generally small, under 2 ha. Moisture relations are intermediate between permanently saturated herbaceous associations and intermittently flooded types. Stands of this vegetation are normally dominated by Calamagrostis nutkaensis, which can contribute up to 70% cover in the canopy. Carex and Juncus species also contribute significant cover. These may include Juncus effusus var. brunneus, Juncus patens, Carex obnupta, Carex densa, and/or Carex harfordii. Common associates may include Scrophularia californica, Rubus spectabilis, Rubus ursinus, Erechtites minimus (exotic), Holcus lanatus (exotic), and/or Iris douglasiana. The canopy is between 1-2 m in height.
