Bearded sedge is a perennial rhizomatous species found in North America in many US states and several Canadian provinces (BC, Ontario, Quebec) (USDA 2011). In British Columbia, it is found in the southwestern and south-central regions in shorelines and wet meadows in the lowland, steppe and montane zones.
In writing about the rare plants of the Fraser Valley, Lomer (2011) says: "Local in the Okanagan, rare elsewhere. Old collections from the Fraser Valley from 1912 (UBC: Henry s.n.) up to 1978. Surprisingly, it was discovered at three new sites in the Fraser Valley in 2008, after going un-noticed for a period of several years. It is well adapted to disturbed marshy shores and should be secure in the protected areas it has been found in: Cheam Wetlands Regional Park (UBC: T. Taylor 116), Burnaby Lake (UBC: Lomer 7065), Sumas Mt waterfowl habitat on private property. Also found in 2010 in a railroad ditch west of Agassiz and a wetland east of Agassiz. I suspect that, though native in the Fraser Valley, it has also been introduced as part of waterfowl enhancement plantings."
