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.
Tiny Tassel (Crossidium seriatum) is a small dark green to golden brown moss. It grows to 1-1.5 mm high, sometimes in clumps but more often as scattered individuals among other species of small dryland mosses. The population of Tiny Tassel in British Columbia represents the northernmost extent of the species’ range in North America. It occurs in Canada only within dry grasslands in the southern interior of British Columbia. These grasslands are a rare habitat type that occupies less than 1% of the British Columbia land base.
This very small moss has a very narrow range in Western Canada. It occurs only in the semiarid shrub steppe of four valleys in the Okanagan region of southernmost central British Columbia. Surveys have confirmed this species from only 20 sites on steep slopes associated with calcareous glacial lake deposits. Threats include erosion due to recreational use of the habitat, and maintenance of road cuts. Climate change may also be a threat, although the potential impacts are unknown. One site has been extirpated due to habitat conversion.
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.
