COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Crumpled Tarpaper Lichen Collema coniophilum in Canada (2011)

    Crumpled Tarpaper Lichen, Collema coniophilum, is a distinctive, moderately sized leafy lichen with several broad, mostly rounded lobes, at most 2-4 (-5) mm wide. The smooth upper surface is dark olive green to blackish brown that becomes weakly and sparsely covered in low “blisters” that eventually expand upwards into low broad ridges. Small, blackish, finger-like protrusions are present on the upper surface, and contrast with the upper surface. The lower surface varies from dark olive green to pale olive beige, and sometimes has tufts of tiny white hairs.

Response Statements

  • Response Statement - Crumpled Tarpaper Lichen (2011)

    This foliose, tree-inhabiting cyanolichen is endemic to Canada where it occupies a narrow range restricted to trees in old-growth forests on calcareous soils in humid, inland British Columbia. The lichen is poorly adapted for dispersal since it has never been found with sexual reproductive structures and its vegetative propagules are not easily dispersed. The lichen has an apparently declining distribution, resulting from ongoing loss of old-growth forest through clear-cut logging. The factors underlying its rarity and narrow endemism are not well understood.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2010 - 2011 (2011)

    Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”. COSEWIC held two Wildlife Species Assessment Meetings during the past year assessing the status or reviewing the classification of a total of 92 wildlife species.

Consultation Documents

  • Consultation on Amending the List of Species under the Species at Risk Act: Terrestrial Species – December 2011 (2011)

    As part of its strategy for protecting wildlife species at risk, the Government of Canada proclaimed the Species at Risk Act (SARA) on June 5, 2003. Attached to the Act is Schedule 1, the list of the species that receive protection under SARA, also called the List of Wildlife Species at Risk. Please submit your comments by February 8, 2012 for species undergoing normal consultations and by November 8, 2012 for species undergoing extended consultations.
