Name: Carex obnupta Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: From Christy (2004): Habitats include isolated depressions with internal drainage, peatlands, shrub swamps, ancient marine terraces, and deflation plains. This association is heterogeneous and difficult to segregate into meaningful types. Stands range from species-rich assemblages to monotypes, and dense to depauperate stands, the latter with only bare mud or sphagnum between the plants. Tussocks may be 15 cm in diameter, closely spaced and 3-9 dm (1-3 feet tall), or 9 dm (3 feet) in diameter, 0.9-1.8 m (3-6 feet) apart and growing up to 1.8 m (6 feet) tall. Trees are mostly peripheral, and <i>Alnus rubra</i> and <i>Fraxinus latifolia</i> are the primary species but have low constancy and cover. Fourteen species of shrubs are reported, with <i>Rubus ursinus</i> having the highest constancy of only 11%. Other shrubs with significant patches include <i>Rosa pisocarpa, Rosa gymnocarpa</i>, and <i>Corylus cornuta</i>. More than 80 species have been recorded from the herb layer, <i>Carex obnupta</i> being most abundant with average cover of 66% and ranging from 20-99%. Other species in the herb layer with significant patches include <i>Athyrium filix-femina, Rorippa nasturtium-aquaticum, Oenanthe sarmentosa, Lysichiton americanus, Veronica americana, Carex exsiccata, Myosotis laxa</i>, and <i>Carex cusickii</i>. The moss layer averages 34% cover and may range up to 95% cover, common species being both <i>Eurhynchium praelongum</i> and <i>Sphagnum mendocinum</i>. Some sites are old beaver swamps, cleared for pasture and then abandoned because they were too wet for livestock. Beaver subsequently reclaimed most of these sites. Elk and beaver use may be heavy.
