CEGL003379 Carex obnupta - Juncus patens Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Slough Sedge - Spreading Rush Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This vegetation grows in seasonally saturated soils on gentle slopes of all aspects. Stands prefer basins, bottoms and plains, which collect water during the rainy season and usually hold water or have saturated soils through most of the growing season. Soils are moderately coarse to fine sandy loams. Stands are generally small, under 2 ha. Moisture relations are close to permanently saturated. Stands of this vegetation are normally dominated by Carex obnupta, which can contribute up to 90% cover in the canopy. Juncus patens is present in all stands and may also contribute significant cover. Other species include Juncus effusus var. brunneus, Juncus phaeocephalus, Juncus arcticus ssp. littoralis, Carex densa, and/or Carex harfordii. Common associates may include Scrophularia californica, Rubus spectabilis, Rubus ursinus, Erechtites minimus (exotic), Holcus lanatus (exotic), Lotus corniculatus (exotic), and/or Iris douglasiana. The canopy is between 1-2 m in height. Baccharis pilularis may cover up to 10% of the stands. Stands with >10% Baccharis are classified as ~Baccharis pilularis / Carex obnupta - Juncus patens Shrubland (CEGL003185)$$.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Carex obnupta often dominates stands of seasonally flooded wetlands along the outer coastal strip of northern California. However, its association with Juncus patens is only known from the Point Reyes/Golden Gate mapping area. Stands with >10% Baccharis are classified as ~Baccharis pilularis / Carex obnupta - Juncus patens Shrubland (CEGL003185)$$.

Environmental Description: This vegetation grows in seasonally saturated soils on gentle slopes of all aspects. Stands prefer basins, bottoms and plains, which collect water during the rainy season and usually hold water or have saturated soils through most of the growing season. Soils are moderately coarse to fine sandy loams. Stands are generally small, under 2 ha. Moisture relations are close to permanently saturated.
Geographic Range: This association is only known from the vicinity of the Point Reyes National Seashore. Information about its global range is not available without additional inventory. Other stands of Carex obnupta have been identified from Humboldt County, California (Pickart and Sawyer 1998), and attributed to the Carex spp. series (Sawyer and Keeler-Wolf 1995).
