PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Vole Ears Erioderma mollissimum in Canada (2010)

    Erioderma mollissimum is a foliose macrolichen with a felty, grey-brown upper surface. When wetted, it turns grey-green. The thallus is up to 12 cm broad and is comprised of radiating, loosely attached lobes to 1 cm in width. The lower surface lacks a cortex (outer protective layer), and except near the pale, bare margins is densely hairy and light-brown. Granular, bluish soredia (asexual propagules) are produced along the lobe margins and may also form in tiny patches on the upper surface of older lobes. The photosynthetic component of this lichen has been identified as Scytonema, a cyanobacterium that is rare in lichens occurring north of subtropical regions.

COSEWIC Assessments

  • COSEWIC Assessment Summary and Status Report: Vole Ears Erioderma mollissimum (2010)

    Assessment Summary – November 2009 Common name Vole Ears Scientific name Erioderma mollissimum Status Endangered Reason for designation This large foliose lichen is known in Canada only from Nova Scotia, New Brunswick, and the island of Newfoundland, where it inhabits cool, humid and coastal conifer forests dominated by Balsam Fir. Although there are 24 known sites for the lichen in these regions, few individuals (133 thalli) are known. While recent surveys have increased the number of known locations, the lichen has been extirpated from 11 sites in the last 30 years. This lichen is a sensitive indicator of air pollution and acid precipitation, which are its main threats. Other threats include forest harvest and browsing by moose. Occurrence New Brunswick, Nova Scotia, Newfoundland and Labrador Status history Designated Endangered in November 2009.

Recovery Strategies

  • Recovery Strategy for the Vole Ears Lichen (Erioderma mollissimum) in Canada (2014)

    As of January 2012, Vole Ears Lichen was known from two populations at 29 sites along the Atlantic Coast of Nova Scotia comprised of 153 adult thalli and from one population at six sites on the Avalon Peninsula in Newfoundland and Labrador that had 26 adult thalli. The last report of Vole Ears Lichen in New Brunswick was from 1980. The species is listed as Endangered on Schedule 1 of the federal Species at Risk Act (SARA).

Action Plans

  • Multi-species Action Plan for Kejimkujik National Park and National Historic Site of Canada (2017)

    The Multi-species Action Plan for Kejimkujik National Park and National Historic Site of Canada applies to lands and waters occurring within the boundaries of Kejimkujik National Park and National Historic Site (KNP and NHS), including Kejimkujik National Park Seaside. The plan meets the requirements for action plans set out in the Species at Risk Act (SARA (s.47)) for species requiring an action plan and that regularly occur within these sites. Measures described in this plan will also provide benefits for other species of conservation concern that regularly occur at KNP and NHS.

Orders

  • Order Acknowledging Receipt of the Assessments Done Pursuant to Subsection 23(1) of the Act (2011)

    His Excellency the Governor General in Council, on the recommendation of the Minister of the Environment, hereby acknowledges receipt, on the making of this Order, of assessments conducted under subsection 23(1) of the Species at Risk Act by the Committee on the Status of Endangered Wildlife in Canada with respect to the species set out in the annexed schedule.
  • Order Amending Schedule 1 to the Species at Risk Act (2012)

    The purpose of the Order Amending Schedule 1 to the Species at Risk Act is to add 18 species to Schedule 1, the List of Wildlife Species at Risk (the List), and to reclassify 7 listed species, pursuant to subsection 27(1) of SARA. This amendment is made on the recommendation of the Minister of the Environment based on scientific assessments by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and on consultations with governments, Aboriginal peoples, stakeholders and the Canadian public.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2010 (2010)

    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”. During the past year, COSEWIC held two Wildlife Species Assessment Meetings and reviewed the status of 79 wildlife species (species, subspecies, populations). During the meeting of November 2009, COSEWIC assessed or reviewed the classification of the status of 28 wildlife species. COSEWIC assessed or reviewed the classification of an additional 51 wildlife species (species, subspecies and populations) during their April 2010 meeting. For species already found on Schedule 1 of SARA, the classification of 32 species was reviewed by COSEWIC and the status of the wildlife species was confirmed to be in the same category (extirpated - no longer found in the wild in Canada but occurring elsewhere, endangered, threatened or of special concern). The wildlife species assessment results for the 2009-2010 reporting period include the following: Extirpated: 6 Endangered: 39 Threatened: 16 Special Concern: 17 Data Deficient: 1 This report transmits to the Minister the status of 46 species newly classified as extirpated, endangered, threatened or of special concern, fulfilling COSEWIC’s obligations under SARA Section 24 and 25. A full detailed summary of the assessment for each species and the reason for the designation can be found in Appendix I of the attached report. Since its inception, COSEWIC has assessed 602 wildlife species in various risk categories, including 262 Endangered, 151 Threatened, 166 Special Concern and 23 Extirpated. In addition, 13 wildlife species have been assessed as Extinct. Also, to date, 46 wildlife species have been identified by COSEWIC as Data Deficient and 166 wildlife species were assessed as Not at Risk. This year has been a particularly productive year for COSEWIC’s Aboriginal Traditional Knowledge (ATK) Subcommittee. In April 2010 COSEWIC approved the Aboriginal Traditional Knowledge Process and Protocol Guidelines, providing clear and agreed principles for the gathering of Aboriginal Traditional Knowledge to carry out COSEWIC functions as required under Section 15(2) of SARA (See Appendix III of the attached report). We are grateful for the rich and enthusiastic contribution made by community elders and experts in helping the ATK Subcommittee prepare the ATK protocols.

Consultation Documents

  • Consultation on Amending the List of Species under the Species at Risk Act: Terrestrial Species – November 2010 (2010)

    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 4, 2011 for species undergoing normal consultations and by February 4, 2012 for species undergoing extended consultations.

Recovery Document Posting Plans

  • Environment and Climate Change Canada's Three-Year Recovery Document Posting Plan (2016)

    Environment and Climate Change Canada’s Three-Year Recovery Document Posting Plan identifies the species for which recovery documents will be posted each fiscal year starting in 2014-2015. Posting this three year plan on the Species at Risk Public Registry is intended to provide transparency to partners, stakeholders, and the public about Environment and Climate Change Canada’s plan to develop and post these proposed recovery strategies and management plans. However, both the number of documents and the particular species that are posted in a given year may change slightly due to a variety of circumstances. Last update March 31, 2017
