Conservation Evaluation of the Pacific Population of Tall Woolly-heads, Psilocarphus elatior, an Endangered Herb in Canada

George W. Douglas, Jeanne M. Illingworth

Abstract


In Canada, Psilocarphus elatior occurs in British Columbia, Alberta and Saskatchewan. This paper examines the status of the Pacific populations located on southeastern Vancouver Island in southwestern British Columbia. The Pacific population consists of 12 recorded sites of which only five have been confirmed since 1993. In British Columbia, P. elatior is associated with dried beds of vernal pools and other open, moist depressions at lower elevations. In British Columbia, P. elatior populations occur in large numbers at only two of the seven locations.
