Description: Barren-ground caribou annual ranges and calving areas by herd (i.e. subpopulation). The supplementary table BIO_ENR_WFE_SARA_AttributeTable contains additional attribute information for this species and its status and range in the NWT. All barren-ground caribou subpopulations considered by COSEWIC (2016) as part of Designatable Unit 3 are included in this shapefile. See COSEWIC (2011) for details on the Designatable Unit. Subpopulation structure of caribou (Rangifer tarandusL.) is as described by Nagy et al. (2011) for the Qamanirjuaq, Ahiak (i.e. Queen Maud Gulf), Beverly, Bathurst, Bluenose-East, Bluenose-West, Cape Bathurst, Lorillard and Wager Bay subpopulations. Other types of caribou (e.g. Dolphin and Union, Peary, mountain woodland, boreal woodland) are not included. Their ranges are available as separate NWT species at risk range shapefiles. Some of their ranges overlap with the barren-ground caribou ranges in this shapefile.Important notes: There is year-to-year variation in the areas used by barren-ground caribou, and there has been range contraction for several herds as they have reached lower numbers. Range information is being updated and is subject to change.If shapefiles are being used to consider potential impacts of development on barren-ground caribou, Environment and Natural Resources recommends seeking further information on seasonal ranges.Polygons were derived using collar data from Government of Nunavut, Government of the Northwest Territories, Yukon Environment and United States Fish and Wildlife Service. “Collar data” provide information on range use by caribou that were collected over many years by remotely tracking locations of caribou fitted with radio-collars using satellite telemetry. Composite shapefile was developed by GNWT ENR, Yellowknife. Details on the origin of each polygon are provided in the table below:Herd (subpopulation)Annual rangeCalving areaPorcupineObtained from the Porcupine Caribou Technical Committee. As displayed on the Porcupine Caribou Management Board website (http://www.pcmb.ca/images/habitat/PCH-Rangemap2.jpg)Prepared by K. Poole (Poole 2011) for CARMA (2012). Cumulative extent of calving (1-21 June) from 1985 – 2010. 90% fixed kernel polygon using all available satellite collar data, obtained from Yukon Environment, combined among years.Tuktoyaktuk PeninsulaCreated byA. D'Hont, ENR in 2013. Produced using caribou collar telemetry data 2006-2012. Contours accumulate the number of unique marked individuals that visit within a 10x10km cell; The contour shown by this polygon is 5%. The percentages are based on the highest count (=100%) of unique collared individuals for that herd occurring within any 10km x 10km block, illustrating the relative degree of use of specific land areas over a defined period of time.

(2011) Fig. 3, based on mean 90% utilization distribution from accumulated collar data 1995-2008There are 2 polygons, a northern and a southern calving ground. Based on BQCMB compilation of all data from government surveys (1957-2011) and telemetry (1996-2012). See Poole (2011) for details.Polygons are as displayed by BQCMB (2014) as well as Nagy et al. (2011, Fig. 1, calving grounds E-1 and F).AhiakGeneralized annual range polygon for ‘Queen Maud Gulf’ from Nagy et al. (2011) Fig. 3, based on mean 90% utilization distribution from accumulated collar data 1996-2008. In 2017, the Ahiak annual range was extended by B.Fournier (ENR) to cover the Queen Maud Gulf calving area produced by J.Nagy, when it was discovered that 2 areas in the northwest and northeast of the calving area were not covered by the annual range polygon.Calving ground E from Nagy et al.
