Small-flowered tonella (Tonella tonella) COSEWIC assessment and status report: chapter 11

Summary of Status Report

Only one extant population of T. tenella is known in British Columbia, thus the loss of the one site results in the loss of the species from British Columbia and Canada. Potential housing developments threaten T. tenella in Canada where the site occurs on private ocean-side property. The population of T. tenella in British Columbia is at the northern extent of its range and may represent a population that is genetically distinct and important for the long-term survival and evolution of the species. Failure to protect peripheral species could result in an irreversible loss of some of Canada’s genetic resources.
