HABITAT TYPES AND PLANT COMMUNITIES : 
Water sedge is often an indicator of riparian or other wetland habitats.
It occurs in disturbed habitats and seral communities, but also is found
in climax arctic habitats.  It is normally dominant or codominant on
sites where it occurs [5,8,21,30,60].

Water sedge is listed as an indicator in the following published
classifications:

Classification and environmental relationships of wetland vegetation in
  central Yellowstone National Park, Wyoming [46]
Forest vegetation of the Gunnison and parts of the Uncompahgre National
  Forests: a preliminary habitat type classification [40]
Riparian community type classification of Utah and southeastern Idaho [52]
Riparian dominance types of Montana [30]

Species commonly associated with water sedge are as follows:  willows
(Salix spp.), other sedges (Carex spp.), tufted hairgrass (Deschampsia
cespilosa), baltic rush (Juncus balticus), bog birch (Betula
glandulosa), leafy aster (Aster foliaceus), spike rush (Eleocharice
pauciflora), narrowleaf cottonsedge (Eriophorum angustifolium), entire
leaf mountain avens (Dryas integrifolia), reedgrasses (Calamagrostis
spp.), sphagnum mosses, and other species typical of riparian areas
[2,10,19,30,37].
