Name: Carex aquatilis var. dives Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: From Christy (2004): Habitat is usually montane fens. The association is widespread and important in the Cascade Range and, like ~<i>Carex aquatilis</i> Herbaceous Vegetation (CEGL001802)$$, includes a heterogeneous mix of species that do not segregate in any meaningful way. Trees and shrubs are scarce, although many different species are present. The herb layer is astonishingly diverse with more than 120 species recorded, but most of these have relatively low constancy and reflect the patchy distribution of many different taxa. <i>Carex aquatilis var. dives</i> is the primary species, averaging 54% cover, and many stands occur as monotypic reed swamp with cover ranging from 5 to 99%. Some of these stands intergrade with ~<i>Carex utriculata</i> Herbaceous Vegetation (CEGL001562)$$ in seasonally flooded depressions. <i>Dodecatheon jeffreyi, Carex utriculata</i>, and <i>Hypericum anagalloides</i> are the only other species with constancy higher than 20%. Species with significant patches include <i>Caltha leptosepala ssp. howellii, Eleocharis quinqueflora, Equisetum fluviatile, Viola macloskeyi, Cicuta douglasii</i>, and <i>Agrostis humilis (= Agrostis thurberiana)</i>. Stands may occur on old beaver terraces on seepage slopes and also in sag ponds on slopes prone to slumping. Carex aquatilis var. dives can intermix with forest ecotone or meadow taxa as long as enough soil moisture is present. Plants become progressively dwarfed as conditions become drier.  Accession Code: VB.CC.34097.CEGL001826 Plot-observations of this Community Concept: 0
