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.
Griscom's Arnica (Arnica griscomii ssp. griscomii) is a small perennial herb with bright- yellow daisy-like flowers. It is a Canadian Gulf of St. Lawrence endemic, and is found only in Québec and on the island of Newfoundland. The flowers, which grow on stems about 20 cm tall, arise from a cluster of leaves that lie almost flat on the ground. These plants spread by rhizomes (underground stems), often forming dense clumps. Dense patches of showy flowers may make this a charismatic species for inspiring public interest in preserving calcareous cliffs, limestone barrens, and their plant life.
This mat-forming plant is a Canadian Gulf of St. Lawrence endemic found only on small, isolated calcareous cliffs and limestone barrens of Quebec and the Island of Newfoundland, is increasingly under threat due to habitat shift in response to a changing climate. The instability of some sites increases the threat of a stochastic event that could result in the loss of some small subpopulations. ATV use in limestone barrens is of some concern.
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 in this reporting year (October, 2014 to September, 2015) from November 23 to November 28, 2014 and from April 27 to May 1, 2015. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species.
The wildlife species assessment results for the 2014-2015 reporting period include the following:
Special Concern: 21
Data Deficient: 1
Not at Risk: 1
Of the 56 wildlife species examined, COSEWIC reviewed the classification of 40 that had been previously assessed. The review of classification for 24 of those wildlife species resulted in a confirmation of the same risk status as the previous assessment.
The Government of Canada is committed to preventing the disappearance of wildlife species at risk from our lands. As part of its strategy for realizing that commitment, on June 5, 2003, the Government of Canada proclaimed the Species at Risk Act (SARA). Attached to the Act is Schedule 1, the list of the species provided for under SARA, also called the List of Wildlife Species at Risk. Extirpated, Endangered and Threatened species on Schedule 1 benefit from the protection of prohibitions and recovery planning requirements under SARA. Special Concern species benefit from its management planning requirements. Schedule 1 has grown from the original 233 to 521 wildlife species at risk.
