Slender wedgegrass occurs primarily in eastern BC. However, it has been collected in the Fraser Valley. Lomer (2011) provides this discussion:
"Collected from dredged sand in Surrey, east of Vancouver (UBC: Lomer 93-73). This grass is known from the Thompson River, as well as other sites in BC, so seeds were probably washed down into the Fraser and sprouted in the dredging. In 2010 a single plant was observed on the sandy meadow shore of an island in the Fraser River southwest of Agassiz. So it appears this species can arise naturally from material washed down the Fraser River from interior sites, thus it should be considered native [in the valley]."
