This page lists the species of lichens that Committee on the Status of Endangered Wildlife in Canada (COSEWIC) recognizes as being at risk in Canada. Each at risk species is assessed and placed in one of the following categories, as defined by COSEWIC:[1]

  • Endangered: A species facing imminent extirpation or extinction.
  • Threatened: A species that is likely to become endangered if nothing is done to reverse the factors leading to its extirpation or extinction.
  • Special Concern: A species that may become threatened or endangered because of a combination of biological characteristics and identified threats.
  • Data Deficient: A category that applies when the available information is insufficient (a) to resolve a wildlife species' eligibility for assessment or (b) to permit an assessment of the wildlife species' risk of extinction.
