Observation Narrative ? Releve also in unpublished thesis of Cooper 1983, Table12, the. 2. Value of Drepanocladus revolvens in his thesis is 65 percent, no Carex aquatilis noted in this work. In thesis, Carex aquatilis is missing, Drepanocladus tundrae occurs with 1 percent cover values - added here. Also Cyrtomnium hymenophyllum (5 percent) is added from original thesis. In original work this releveis a part of Schistidio-Drepanocladetum revolventis - note by J. Sibik, 01-22-2014. Fens and marshes are limited to valley bottoms in the Arrigetch Peaks and are especially abundant where glacial moraines have ponded valleysand these ponds have been subsequently filled by alluvium. The Paludello squarrosae-Caricetum aquatilis is the most abundanttype of fen occurring ongranitic outwash sands of level cirque floors andvalley bottoms. Thaw depth about 1 m (Cooper 1986b).
