State Rank Reason (see State Rank above)
Carex glacialis occurs throughout Canada, and has recently been discovered in the United States where it occurs at 4 locations in Montana. It grows in limestone fellfield habitats within the alpine. Populations are few, but appear stable. Surveys are needed to explore potential habitat, map its distribution, and determine population sizes.
