click to update datacart
Name: Trichophorum cespitosum Pacific Fen Reference: NatureServe Biotics 2019 Description: Habitat is montane fens, forming wet lawns on flats or gentle to moderate slopes below springs and seeps. <i>Trichophorum cespitosum</i> forms conspicuous tussocks in montane peatlands but is not common in Oregon. The habitat is similar to other montane fens in similar sloping, seepy sites. Trees have scanty cover and are primarily restricted to hummocks or "tree islands" within a matrix of wet lawn, or they are peripheral to the wetland. Species include <i>Pinus monticola, Thuja plicata, Tsuga heterophylla</i>, and <i>Abies amabilis</i>, but all have low constancy and cover. Nine different species are reported from the shrub layer, the primary one being <i>Vaccinium uliginosum</i>, but these also have low constancy and cover. Over 40 species are reported from the herb layer, most of them typical of wet lawns in fens. <i>Trichophorum cespitosum</i> is most abundant with 44% cover and ranging from 20-75%. <i>Triantha glutinosa</i> is present in all plots but with low cover. Other species with significant patches include <i>Hypericum anagalloides, Caltha leptosepala ssp. howellii, Sanguisorba officinalis, Eriophorum gracile, Carex aquatilis var. dives</i>, and <i>Carex utriculata</i>. <i>Trichophorum cespitosum</i> is uncommon in Oregon, and occurrences of this association are limited to the northern part of the Cascade Range.  Accession Code: urn:lsid:vegbank.org:commConcept:31587-{C0582748-6836-47CD-BF40-4504AFD3CBEB} Plot-observations of this Community Concept: 0
