Sable Island is shown as a circle, Poundnet Bay as a triangle. Squares denote extirpated populations. relatively small, both in number and area, and there- fore are vulnerable to environmental disturbance. If development at any of the remaining populations pro- ceeds without consideration for this species it will very likely be extirpated from Canada. In particular, altera- tion of natural water level cycles could result in the destruction of the habitat required by Lipocarpha mic- rantha. The authors" recommendation that Lipocarpha micrantha be uplisted to Endangered was accepted by COSEWIC in November 2002.
