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.
The Sable Island Sweat Bee, Lasioglossum sablense Gibbs, is a small (5–6 mm), dull-metallic sweat bee in the family Halictidae. The species is endemic to Canada, occurring solely on Sable Island, Nova Scotia. Both sexes can be distinguished from the three other bee species (two of these sweat bees) on Sable Island by the combination of their small size and the dense lateral punctures on the dorsal part of the thorax.
This species is globally endemic to Sable Island, Nova Scotia, and occurs as one isolated population with a very small range and no possibility of rescue. The island has only about 13 km2 of vegetated area that provides forage/nesting sites for this bee. Nesting likely occurs near or within this vegetated area and sweat bees are not known to travel large distances (i.e. > 200 m) for forage. Increased frequency and severity of storms, in addition to climate change and related sea level rise, are expected to drive change which will further decrease the quality and quantity of bee habitat on the island. Eco-tourism is also a potential future threat, which may also increase the introduction and spread of invasive species. Habitat on the island is also susceptible to invasive plant species, introduced horses, and seawater flooding.
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.
