CEGL003317 Juncus effusus var. brunneus Pacific Coast Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lamp Rush Pacific Coast Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Habitat is meadows, fens, and old pastures. This association is generally thought of as a disturbance type resulting from grazing, but some occurrences suggest that it is native in some places because they are unlikely to have ever been heavily grazed. It is widespread at a variety of elevations but is especially abundant at low elevations in western Oregon. The plots here are from the Coast Ranges and Cascade Range. Trees are nearly absent but may include Alnus rubra, Fraxinus latifolia, Quercus garryana, or conifers peripheral to the wetland. Eight shrub species are recorded, with Salix sitchensis being most abundant, but their cover is negligible. The herb layer includes about 60 different species, with Juncus effusus being most abundant with an average cover of 52% and ranging from 20 to 85%. Juncus ensifolius is a consistent associate but has very low cover, while Hypericum anagalloides is much more abundant but present with slightly lower constancy. Other species occurring in significant patches include Scirpus microcarpus, Equisetum arvense, Oenanthe sarmentosa, and Athyrium filix-femina, and five species are exotics. Old pastures at low elevations may also have large amounts of Ranunculus repens, but this species was not recorded in these plots.

Floristics: Trees are nearly absent but may include Alnus rubra, Fraxinus latifolia, Quercus garryana, or conifers peripheral to the wetland. Eight shrub species are recorded, with Salix sitchensis being most abundant, but their cover is negligible. The herb layer includes about 60 different species, with Juncus effusus being most abundant with an average cover of 52% and ranging from 20 to 85%. Juncus ensifolius (= Juncus xiphioides var. triandrus) is a consistent associate but has very low cover, while Hypericum anagalloides is much more abundant but present with slightly lower constancy. Other species occurring in significant patches include Scirpus microcarpus, Equisetum arvense, Oenanthe sarmentosa, and Athyrium filix-femina, and five species are exotics.

Environmental Description: This association is only known from the vicinity of the Point Reyes National Seashore, and the Puget Trough region. Information about its global characteristics is not available without additional inventory. Vegetation fitting the general description of this association has been identified in coastal wetlands throughout much of California. Juncus effusus var. brunneus is the common coastal variety that is likely to compose most of these stands (Hickman 1993).
Geographic Range: This association is reported from the vicinity of the Point Reyes National Seashore, as well as from the Puget Trough region of Washington and British Columbia. Information about its global range is not available without additional inventory. Other stands of Juncus effusus have been identified from Humboldt County to Monterey County, California. However, there has been no systematic sampling of these stands to identify floristic affinities.
