Conservation evaluation of Stoloniferous Pussytoes, Antennaria flagellaris, in Canada

摘要

In Canada, Stoloniferous Pussytoes, Antennoria flagellaris, is restricted to the Similkameen River valley south of Princeton, in south-western British Columbia. The three populations represent the northern limits of the species which ranges from southwestern British Columbia, south in the western United States to Idaho, Wyoming, Nevada and California. In British Columbia, Antennaria flagellaris is associated with eroded, unstable, calcareous clay seepage slopes on open, southerly aspects. This habitat is infrequent in the Similkameen River area and the few existing plant populations could easily be extirpated through slight changes in drainage through drilling for coalbed methane gas, road-building, or housing development.
