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.
Vivid Dancer is a robust damselfly (Order Odonata) 29.5 – 35mm long. Adult males are typically bright blue or occasionally violet blue, both forms with black markings. Females resemble males or may have more subdued colours, typically orange or red-brown and black. Vivid Dancer is distinguished from similar damselflies in other genera by wing venation patterns, the shape of reproductive structures, and comparatively longer leg spines. Vivid Dancer larvae are short, stocky and flattened, with broad, heavily pigmented, leaf-like gills.For much of its Canadian range, Vivid Dancer is a specialist of thermal spring habitats. The species is the only documented odonate adapted to breed in geothermal springs in North America. The floral and faunal communities within thermal springs vary from site to site.
This damselfly is found in southern British Columbia and Banff, Alberta. Through much of its Canadian range it is restricted to thermal springs, but in the hot valleys of the Okanagan and the Fraser it is also found in cooler, spring-fed creeks. Habitat loss and degradation at most sites suggest subpopulations have declined. The species is threatened by intensive recreational use of thermal springs, livestock trampling at cool springs, and introduced fish. Sites are also vulnerable to potential tourism development and changes in springs caused by events such as droughts, earthquakes and landslides.
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.
