Response Statements

Response Statement - Tubercled Spike-rush

In Canada, this sedge is known to exist only along peaty and sandy shorelines at six lakes in southwestern Nova Scotia.  The use of all-terrain vehicles along the shores of the two larger lakes, where most of the Canadian population occurs, has degraded portions of the species’ habitat. Cottage development and related impacts (water quality and habitat disturbances) are currently limited threats that have the potential to increase in the future. More intensive surveys of lakeshore habitats indicate that the species is somewhat more abundant than previously documented.
