Description: NWT Species range distribution for the Gypsy Cuckoo Bumble Bee (Bombus bohemicus). The approximate range of Gypsy Cuckoo Bumble Bee (Bombus bohemicus) was created by Joanna Wilson, Bonnie Fournier and Suzanne Carriere (ENR) in August, 2014, updated on October 2, 2014, and reviewed but not changed in October 2015. The range was based on specimen records of Bombus bohemicus from Williams et al 2014 (Bumble Bees of North America; NWT specimen database provided by Leif Richardson, a full list of contributors to the database can be found at http://www.leifrichardson.org/bbna.html). The range north of 60 degrees latitude approximated Canadian Ecozones where the species had been found (Taiga Plains and Boreal Cordilera). Range elsewhere in North America was sketched around the records of Bombus bohemicus mapped in the COSEWIC 2014 status report on Gypsy Cuckoo Bumble Bee. The range in Quebec and Labrador extends northward to encompass Shefferville, Quebec based on input from Isabelle Gauthier and Nathalie Desrosiers (Quebec MFFP).The range was updated in 2019 during the development of the national recovery strategy for gypsy cuckoo bumble bee. The update used new recorded observations provided by Syd Cannings (see the recovery strategy for a list of presumed extant subpopulations in western Canada). The new range is based on an EBAR (Ecosystem-based automated range mapping) range created by Suzanne Carriere, ENR and Natureserve Canada. The EBAR range polygon was smoothed by Bonnie Fournier, ENR, using the ArcMap 10.6 Cartography tool.In September 2025, Joanna Wilson and Robin Abernethy (GNWT ECC) added polygons obtained from Canadian Wildlife Service indicating the area containing critical habitat, as defined in the final Recovery Strategy for Gypsy Cuckoo Bumble Bee in Canada (ECCC 2025, available from sararegistry.gc.ca). These are the areas within which critical habitat for gypsy cuckoo bumble bee occur. Critical habitat as defined by the Species at Risk Act occurs within these polygons where certain biophysical features are found, as laid out in the recovery strategy section 7.1. Critical habitat is not necessarily the entire polygon. The spatial data came from the ECCC Data Catalogue: Critical Habitat for Species at Risk National Dataset - Canada (catalogue.ec.gc.ca), retrieved on September 5, 2025. Also in September 2025, the continental range for Gypsy Cuckoo Bumble Bee was updated to match the recent EBAR range from NatureServe, which incorporates new species occurrences.
