Bolander’s quillwort (Isoetes bolanderi) COSEWIC assessment and status report: chapter 11

Special Significance of the Species

The Isoetes bolanderi population at Summit Lake is the northernmost in North America. Due to their susceptibility to environmental changes, such as temperature change and water chemistry, aquatic Isoetes provide excellent ecological integrity indicators (Voge 1997). Accordingly, the size and health of the I. bolanderi population at Waterton Lakes National Park could provide a valuable indicator of environmental change.
