Habitat requirements of the yellow glacier lily, Erythronium grandiflorum Pursh, were studied at 38 sites in southern British Columbia and southwestern Alberta.

For example, during the summer months, St'at'imc, Nlaka'pamux and Secwepemc women would dig the corms of Yellow Glacier Lily (Erythronium grandiflorum).

Grizzly bear digging for bulbs of glacier lily (Erythronium grandiflorum) enhances soil nutrients on those sites, encouraging regrowth and productivity of glacier lilies and other plants and structuring plant communities (Tardiff and Stanford 1998).
