Name: Carex nigricans Wet Meadow
Reference: NatureServe Biotics 2019
Description: Habitat is depressions and seepy alluvial fans in subalpine heath. This association is somewhat drier than ~<i>Salix commutata / Carex scopulorum</i> Wet Shrubland (CEGL001189)$$ but intergrades with it. It also intergrades with ~<i>Carex scopulorum</i> Wet Meadow (CEGL001822)$$ and upland <i>Phyllodoce empetriformis</i> heath. Stands on alluvial fans occur below springs and seeps and may be laced with rivulets or irrigated by sheetflow. Trees are absent and shrubs are confined to hummocks. <i>Salix commutata</i> is the primary shrub but averages only 10% cover and does not exceed 20% cover. <i>Kalmia microphylla</i> is also present with about half as much constancy and cover. The herb layer has over 35 different species present, but most occur at low constancy and cover. <i>Carex nigricans</i> is present in all plots with an average cover of 33%, ranging from 5-95%. Other herbs with significant patches include <i>Carex scopulorum, Ligusticum grayi</i>, and <i>Caltha leptosepala ssp. howellii</i>. About half of the remaining herbs are wet lawn species and half are drier meadow species. This is not a productive habitat and considerable bare ground may be present in plots.
