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.

Description: The Boreal Woodland Caribou population range was derived from the COSEWIC status report, Boreal Caribou National Technical Steering Committee files, and extensive input from ENR regional Biologists (Nic Later, Dean Cluff, Deb Johnson, Alasdair Vietch, and John Nagy). 2009 update: new boreal caribou ranges and northern mountain ranges based on updated research and findings with input from John Nagy. 2012 update: Rob Gau updated the NWT boreal caribou range based on collar location data and extensive input from ENR regional Biologists. This version of the range was used by Environment Canada in the 2012 National Recovery Strategy for Boreal Caribou. In June 2015, the range was corrected by ENR staff (A. Smith, B. Fournier, J. Wilson & J. Hodson) to fix oversights from 2012. Fixes included the following: Incorporating Big Island and surrounding islands (where Great Slave Lake flows into the Mackenzie River); extending the NWT range all the way to the Alberta border to fill a small gap; and other minor edits that were made in 2012 but had not been fully incorporated into the master file. The revised shapefile was provided to Environment Canada in June 2015. In 2016 the boundary was adjusted to line up with the Alberta/NWT border (A. Smith, ENR).

Description: The NWT range of collared pika was developed by ENR HQ (Suzanne Carriere) after initial review of the COSEWIC status report in 2011. Data was compiled by Bonnie Fournier, ENR HQ, with comments from ENR Regional Biologists (Alasdair Veitch, Richard Popko, Nic Larter, and Danny Allaire) and additional input from the WMAC (NWT). It was updated in December 2013 by Joanna Wilson (ENR). At that time, the range was slightly extended eastward in Nahanni National Park Reserve to incorporate a collared pika record. This change was reviewed with ENR staff as well as Doug Tate (Parks Canada) and Donna Bigelow (Environment Canada).

Description: The suspected range for Eastern Red bat in theNorthwest Territories was developed by Joanna Wilson and Bonnie Fournier, GNWT ECC, in January 2024. The range in the NWT was based on ecoregion-based range mapping (EBAR) for eastern red bat as shown in the Management Plan for Bats in the Northwest Territories (2020). It includes Level IV ecoregions where eastern red bat is classified as 'presence expected'. The evidence for this species' presence includes sightings and acoustic recordings but so far no confirmed records (captures or specimens). Continental range (outside of NWT) was based on spatial data obtained from Cory Olson which he used to create range maps in the COSEWIC 6-month interim status report (COSEWIC Status Report on hoary bat, eastern red bat, and silver-haired bat in Canada, 2022).

Description: This is the distribution (range and areas of increased presence) of the Western population of grizzly bear; the Ungava population is extinct. The range for all of North America is shown. The grizzly bear range for the Northwest Territories was dramatically altered from data provided by NatureServe 2007. NatureServe reference is Hall 1981. NWT range was developed by ENR HQ (Rob Gau) and comments from ENR Regional Biologists (Marsha Branigan, Alasdair Veitch, and Nic Larter) with additional input from the WMAC (NWT) and Sachs Harbour and Ulukhaktok HTCs in 2012. Nunavut range developed with Matthieu Dumond and Malik Awan (Government of Nunavut). Additional 2012 updates: BC range developed from files provided by Byron Woods (Government of BC). AB range developed from files provided by Nathan Webb (Government of AB). MB range developed from files provided by William Watkins (Government of MB). Areas of increased presence on northern Victoria Island and southern Melville Island were extended in August 2016 to incorporate recent unpublished grizzly bear observations (Jodie Pongracz, pers. comm.). Changes were reviewed by M. Branigan, B. Fournier, R. Gau, J. Pongracz, R. Mulders and J. Wilson (GNWT ENR) as well as M. Awan (Govt of Nunavut).

Description: The hoary bat range for Northwest Territories was developed by Joanna Wilson and Bonnie Fournier, GNWT ECC, in January 2024. The range in the NWT was based on ecoregion-based range mapping (EBAR) for hoary bat as shown in the Management Plan for Bats in the Northwest Territories (2020). It includes Level IV ecoregions where hoary bat is classified as 'confirmed' or 'presence expected'. Gaps between ecoregions in the Mackenzie mountains were also filled in. Continental range (outside of NWT) was based on spatial data obtained from Cory Olson which he used to create range maps in the COSEWIC 6-month interim status report (COSEWIC Status Reporton hoary bat, eastern red bat, and silver-haired bat in Canada, 2022).

Description: The little brown myotis range for the Northwest Territories was created in 2012. It was adapted from NatureServe 2002 and edited to reflect data from NWT ENR Infobase 2012. ENR WMIS, and records compiled by Joanna Wilson for the draft manuscript ‘Diversity and distribution of bats in the Northwest Territories’. Shapefile was created in March 2012 by Dallas Phillips and Joanna Wilson (ENR) and was reviewed by Allicia Kelly (ENR), Danny Allaire (ENR), Dean Cluff (ENR), Rob Gau (ENR), Cori Lausen and Jesika Reimer. The NWT range was updated in January 2014 by Joanna Wilson and Bonnie Fournier (ENR). 2014 updates were to reflect new data from the manuscript, Wilson et al (in prep.) Diversity and Distribution of bats in the Northwest Territories. Revisions were reviewed with Cori Lausen, Jesika Reimer, Parks Canada staff (Doug Tate and Sharon Irwin), ENR staff (Danny Allaire, Suzanne Carriere, Rob Gau, Iga Stasiak, Michelle Swallow, Dean Cluff) and Donna Bigelow (Environment Canada). The NWT range was reviewed again by Jesika Reimer and Joanna Wilson in October 2015 but no changes were made. In December 2019, during the development of the NWT management plan for bats, the range was updated by Joanna Wilson and Bonnie Fournier, ENR, to reflect 2017 acoustic records of little brown myotis on the east arm of Great Slave Lake (obtained from IngeJean Hansen of Zonal Ecosystem and Wildlife Consultants) as well as 2019 species records from Fort Resolution (ENR unpubl. data).In December 2019, polygons were added indicating the Area Containing Critical Habitat. These 100 x 100 km standardized UTM grid squares indicate the area within which critical habitat (hibernacula) for little brown myotis is found in the NWT, as defined by the national Recovery Strategy for little brown myotis, northern myotis, and tri-colored bat in Canada (ECCC 2018). Critical habitat as defined by the Species at Risk Act occurs within these polygons only where hibernacula have been identified. Critical habitat is not the entire polygon.Note that the northern limit of Little Brown Myotis range in the NWT is not well known.There is also a single point record, thought to be extra-limital, from Colville Lake NWT(approximate location 67.033463, -126.118719).That single Little Brown Myotis specimen was collected October 3, 2012 in Colville Lake NWT by Stephanie Berens (ENR - Sahtu Region). Species identification by Joanna Wilson (ENR). As of Jan 2016 this was the northernmost bat recorded in North America. The northernmost limit of Little Brown Myotis range in the NWT is not well known but this single record from Colville Lake is thought to be extra-limital.The rest of the continental range (outside of NWT) reflects the range shown in the draft national recovery strategy for little brown myotis (sararegistry.gc.ca). This continental shapefile was shared by Environment Canada with NWT species at risk program on October 23, 2015 and the range was updated to match on Feb 23, 2016, with the addition of Prince Edward Island (based on information in the COSEWIC status report and national recovery strategy).

Description: NWT Species range distribution for the Northern Mountain Woodland Caribou population. The shapefile includes the range (known distribution) and areas of trace occurrences. The national mountain woodland caribou range was updated by Bonnie Fournier (ENR) for COSEWIC with input from all jurisdictions in August, 2013and finalized in May, 2014. At that time, the Northwest Territories northern mountain caribou population range was updated by the GNWT Regional biologists from the Sahtu and Dehcho regions.In April 2021, Bonnie Fournier (ENR) updated the range to incorporate new information on Yukon herd ranges obtained from Government of Yukon biologists in 2018 as part of the development of the NWT Species at Risk Committee Status Report.In January 2024, Joanna Wilson and Bonnie Fournier (GNWT ECC) updated the Range by expanding it to the southeast in the Nahanni / Prairie Creek area. Its extent in that area now matches the combined annual ranges of all herds that occur within Nahanni (based on the analysis in the report ‘ Spatial Analyses for Nahanni and Nááts'įhch'oh National Park Reserve Caribou, Prepared By: Chrysalis Ecological, Prepared For: Colleen Murchison, Parks Canada Agency, October 2023’.) This extended range also encompasses 2022 and 2023 data collected from collared caribou (GNWT ECC Dehcho region). This change was reviewed with biologists from GNWT ECC, Parks Canada, and Yukon Government.

Revisions were reviewed with Cori Lausen, Jesika Reimer, Parks Canada staff (Doug Tate and Sharon Irwin), ENR staff (Danny Allaire, Suzanne Carriere, Rob Gau, Iga Stasiak, Michelle Swallow, Dean Cluff) and Donna Bigelow (Environment Canada). Updated 9 November 2015 by Jesika Reimer (Alaska Natural Heritage Program) and Joanna Wilson (ENR) - at that time the western expansion was sent to staff of B.C., Alberta and Yukon governments for review. Prince Edward Island was added to the range in February 2016 based on information from the draft national recovery strategy and R. Barclay pers. comm. Range in B.C. and Yukon was updated in August 2016 reflecting input from Cori Lausen (Wildlife Conservation Society) and Tom Jung (Govt of Yukon); the western range boundary in B.C. was adjusted to excluderecords in the Lillooet area (Sarell et al. 2010) that were not genetically confirmed, but includegenetically confirmed records from Hazelton and Staubert Lake B.C.. Yukon records from Tom Creek and Coal River Springs are also included. Revisions were reviewed by staff of BC and AB governments as well as ECCC. Revised shapefile provided to ECCC in September 2016 for use in federal recovery strategy.In October 2022, Nick Wilson and Joanna Wilson (GNWT ENR) updated the range by expanding it slightly to the northwest in the Mackenzie Mountains, NWT to include new Northern Myotis occurrences in the Howard's Pass area from acoustic monitoring (EDI Environmental Dynamics Inc. 2020, Howard's Pass Access Road Baseline Wildlife Studies 2019-2020 Annual Report); shapefile was also cleaned up the edge along the Yukon border to resolve minor geometry issues with vertices.

Description: The original Peary caribou range was derived from the COSEWIC status report then edited to incoporate comments from John Nagy (ENR), and Debbie Jenkins (Gov of NU Peary Caribou biologist); it was updated in 2008. The range was reviewed in 2012 but no changes were made at that time.In 2022, the range was updated by GNWT ENR (Nick Wilson and Joanna Wilson) to match spatial data provided by Canadian Wildlife Service (Isabelle Duclos) reflecting the Peary caribou range depicted in the Recovery Strategy for the Peary Caribou in Canada (ECCC 2022, available from sararegistry.gc.ca), which includes King William Island. The range matches the 'core range' depicted in ECCC 2022 and does not include 'areas outside the core range'.The previous range shapefile used by GNWT ENR had glaciated areas in the high arctic of Nunavut clipped out but the new range from ECCC does not.In October 2022, Nick Wilson and Joanna Wilson (GNWT ENR) added polygons obtained from Canadian Wildlife Service indicating the Area Containing Critical Habitat in the NWT, as defined in the Recovery Strategy for the Peary Caribou in Canada (ECCC 2022, available from sararegistry.gc.ca). Sea ice crossings are identified as critical habitat for Peary caribou. This feature showsthe areas within which critical habitat for Peary caribou occur in the NWT. Critical habitat as defined by the Species at Risk Act occurs within these polygons where the criteria for biophysical attributes are met, as laid out in the recovery strategy. For example: "Sea ice is an essential component of Peary Caribou habitat as corridors for annual movements between islands. This habitat is seasonal and exists from when it starts forming in the fall until ice breakup in the following spring or summer. To account for this temporal feature and to protect the formation of ice from shipping and ice-breaking, all the sea ice habitat identified [in recovery strategy maps] is to be considered as critical habitat.

Description: NWT Species range distribution for Ringed Seal created by Bonnie Fournier and Joanna Wilson, ENR, in December 2019. The range is as depicted in the COSEWIC 2019 2-month interim status report for ringed seal. The range is only valid for North America because of projection issues near the North Pole region. This range has been adapted from the known spatial distributions (i.e., ranges) of the five subspecies of ringed seals (Phoca hispida) produced as part of a U.S. Endangered Species Act status review for the National Oceanic and Atmospheric Administration (NOAA). The boundaries are based on previously published range maps and/or descriptions of the species' distribution in published or unpublished accounts. All boundaries should be considered approximate. Spatial distribution obtained from https://data.noaa.gov/dataset/dataset/ringed-seal-distribution. Spatial distribution was modified by Bonnie Fournier and Joanna Wilson in April 2021, with agreement from DFO (Sam Stephenson), by clipping the Arctic islands out of the range.

Description: The Silver-haired bat range for Northwest Territories was developed by Joanna Wilson and Bonnie Fournier, GNWT ECC, in January 2024. The range in the NWT was based on ecoregion-based range mapping (EBAR) for silver-hairedbat as shown in the Management Plan for Bats in the Northwest Territories (2020). It includes Level IV ecoregions where silver-hairedbat is classified as 'confirmed' or 'presence expected'. Continental range (outside of NWT) was based on spatial data obtained from Cory Olson which he used to create range maps in the COSEWIC 6-month interim status report (COSEWIC Status Report on hoary bat, eastern red bat, and silver-haired bat in Canada, 2022).

Description: NWT Species range distribution for Wolverine, showing the range (known distribution) as well as areas of increased presence. This shapefile also incorporates the rest of the Canadian distribution, which includes the historical range and areas with unverified observations of wolverine (see COSEWIC 2014 status report for details). NWT range map was originally adapted from NatureServe 2002 and edited in 2008 to fit the COSEWIC (2003) status report and comments from Marsha Branigan (ENR). NWT range map was updated in 2014 for COSEWIC to include range of 'Increased Presence' on the Arctic Islands by Marsha Branigan(NT) and Malik Awan (NU).

Description: Adapted from files provided from the National Wood Bison Recovery Team. Individual populations/subpopulations are identified. Status of populations (diseased, free-ranging and captive) are identified. 'Free-ranging' also indicates disease-free, i.e. that the herd is free from bovine tuberculosis and brucellosis. NWT ranges were edited to reflect new data from Dehcho, North Slave, and South Slave Regions and Regional Biologists in August 2012. South Slave region populations were updated on September, 2013. The Nyarling population was updated in December 2013 and the Mackenzie population range was updated by Bonnie Fournier, ENR in October 2019 based on input from Terry Armstrong (ENR).The Mackenzie population range was updated again by Nick Wilson and Terry Armstrong (ENR) in October 2022 to exclude Big Island and other islands in Great Slave Lake.

Description: The range map was compiled from the most current data as of December 2015. Extensive point observation data collected by the Canadian Wildlife Service helped to identify breeding ranges for Migratory Bird Species at Risk in the Northwest Territories and Nunavut (Nature Serve, GNWT, Wildspace, NWT-NU Bird Checklist Survey, 2009, L. Armer & C. Machtans, 2009, S. Hache & R. Pankratz, 2014, Ebird 2014).In October 2022, Nick Wilson and Joanna Wilson (GNWT ENR) added polygons obtained from Canadian Wildlife Serviceindicating the Area Containing Critical Habitatin the NWT, as defined in the Recovery Strategy for the Bank Swallow in Canada (ECCC 2022, available from sararegistry.gc.ca). These are the areas within which critical habitat for bank swallow occur in the NWT, at certain places along the Mackenzie River, Arctic Red River, and Caribou Creek. Critical habitat as defined by the Species at Risk Act occurs within these polygons where criteria related to bank swallow nesting and foraging are met, as laid out in the recovery strategy. Critical habitat is not necessarily the entire polygon.

Description: Polygons delineating the range extent within which Shortjaw Cisco may be found.This data is provided to NWT by the DFO Species at Risk program. Updated October 2022.Prior to 2022, the old shapefile included "actual" range (up to Great Slave Lake) and "estimated range" (up to Great Bear Lake). In October 2022, the range map was updated by GNWT ENR (Nick Wilson and Joanna Wilson) following information and advice from DFO (Peter Jarvis, Joshua Stacey, Abigail/Biggie Theano-Pudwill) to extend the range to include Great Bear Lake. This is based on work showing that shortjaw cisco, or a shortjaw-like form, has been found in Great Bear Lake. See technical report by Howland et al. (2013) "Variation in morphology, life history and ecology of cisco in Great Bear Lake, Northwest Territories, Canada". See also Leclaire, M. MSc. thesis 2016 "Cisco (Coregonus spp) diversity in Great Bear Lake Northwest Territories, Canada". The 2003 COSEWIC report also acknowledges this location and states that the species was collected in Great Bear Lake by in 2003 by Randy Eshenroder (Great Lakes Fishery Commission, Ann Arbor, MI, pers. comm.) and Kim Howland (Dept. Fish. Oceans Canada, Freshwater Inst., Winnipeg, Manitoba). Cisco taxonomy is very complex.Additional notes on past records, from old 2014 metadata:Shortjaw Cisco is present at least in Great Slave Lake (B011, B059). The NT distribution area was extended east to include the Tazin River (Harper and Nichols 1919 in B172) however, this riverine occurrence is unsound from the perspective of the species’ biology and habitat preferences (see above). Early identifications such as this appear to represent mis-identifications based upon the uncertain and incomplete taxonomy of the day. Accordingly, although shown on the map, we consider this point as most likely representing a variant form of Cisco (C. artedi). Examination of museum specimen(s) if available and re-sampling of this area are both required.

Description: Distribution of Western Toad in the Northwest Territories and Canada. Originally adapted from NatureServe 2002:NatureServe references: Stebbins 1985 and Blackburn et al. 2001. Edited to reflect new data from Danna Schock (ENR field work 2007), CFN 120:87-92, CARCNET, and NWT ENR Infobase. Range in Alberta verified by Kris Kendall (AB Conservation Assoc. - pers. com.) and data provided by Lisa Wilkinson (Gov of AB) and the Government of AB WMIS. Range in British Columbia verified by Laura Friis (Gov of BC - pers. com.). Range in Alaska verified by Sanjay Pyare (University of Alaska) and Blain Anderson (Gov of Alaska). Range in Yukon verified by CFN 120:87-92 and Brian Slough (Yukon Coordinator FrogWatch - pers. com.). This range was clipped to exclude glaciated areas.The NWT portion of the range was updated in December 2013 to follow the boundaries of the two NWT level 4 ecoregions with confirmed western toad records. The ecoregions are Liard Upland Mid-boreal and Liard Plain Mid-boreal (Ecosystem Classification Grop 2007 revised 2009). Slight changes to the range in northern B.C. and southeast Yukon were also made to align them with the new NWT range. Changes were reviewed with ENR biologists as well as Danna Shock, Doug Tate (Parks Canada), Brian Slough and Tom Jung (Yukon) and Purnima Govindarajulu (B.C.).

Description: The approximate range of Transverse Lady Beetle (Coccinella tranversoguttata) was created by Joanna Wilson, Bonnie Fournier and Angus Smith in October 2017. Paul Grant shared Canadian species records from his database to inform the creation of the map. The range map shown in Figure 2 of the COSEWIC 2-month interim draft report (2016) was used as the starting point. It was based on a historical range map by Gordon (1985) as well as Paul Grant’s collection data. It was digitized by hand & eye because GIS shapefiles were not available. The northern part of the range was then modified. The original range shown in the COSEWIC figure included quite a bit of Nunavut and northern Quebec; this was based on a Nunavut record with an unknown location that defaulted to the geographic center of the territory. We omitted this record because its actual location is not known. Then we re-drew the northern edge of the range using the occurrence database combined with ecological regions as a guide. Draft range map was circulated for review to representatives of provincial/territorial governments within the range, Environment and Climate Change Canada, COSEWIC Secretariat, and Paul Grant.Note that occurrence in Nunavut is possible based on the record labelled “NU” and on the fact that part of Nunavut is below tree line.

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, afull 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 bohemicusmapped 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.

Description: NWT Species range distribution for the McKay's Bumble Bee (Bombus mckayi).This was formerly considered a subspecies of the Western Bumble Bee (Bombus occidentalis mckayi) but is now recognized as a full species. Range is the same as the range of the previously recognized northern subspecies Bombus occidentalis mckayi. The approximate range was originally drawn by Jenny Wu (COSEWIC Secretariat) and Jennifer Heron (writer of COSEWIC status report) in June 2014. Shapefile was based on information in the COSEWIC 2014 status report on western bumble beeBombus occidentalis, including the maximum entropy habitat model, and geographic locations of specimens compiled by Leif Richardson for Williams et al 2014 (Bumble Bees of North America). The range was adapted for the NWT by Joanna Wilson and Bonnie Fournier (ENR) in August, 2014. The projection and metadata were updated but no changes were made to the range as originally mapped. Reviewed again in October 2015 but no changes made. In October 2022, Nick Wilson and Joanna Wilson (GNWT ENR) updated the layer by changing it to the new species name, McKay's Bumble Bee, and removing the range of Bombus occidentalis.

Description: The approximate range of Yellow-banded bumble bee (Bombus terricola)was created by Joanna Wilson and Bonnie Fournier in October 2015. Range in the U.S. was sketched around the records of Bombus terricola mapped in the COSEWIC 2015 draft status report on yellow-banded bumble bee. The Canadian range is based on specimen records of Bombus terricola up to 2013 in the unpublished database ‘Bumble bees of North America’provided by Leif Richardson (afull list of contributors to the database can be found at http://www.leifrichardson.org/bbna.html). Additional 2014 records from southeast Yukon were provided by Syd Cannings and Jenny Wu. Note that the colouration of Bombus terricola can be very similar to Bombus occidentalis where the two species overlap therefore there is some uncertainty in species identification; the identification of records around Vancouver and on Vancouver Island B.C. should be verified (Cory Sheffield pers. comm. Oct 2015). The range was updated in December 2019 using new recorded observations in Inuvik provided by Syd Cannings. The northern NWT part of the 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 using the ArcMap 10.6 Cartography tool.

Description: Known range of the Hairy Braya (Braya pilosa), based on information in the report Species at Risk Committee (2012) 'Species Status Report: Hairy Braya (Braya pilosa) in the Northwest Territories', which is available here: http://nwtspeciesatrisk.ca/pdf/Hairy_Braya_NWT_status_report_Dec_2012.pdf.The 'possible range' was mapped by ENR using satellite imagery. This area appears to contain additional unglaciated, inland dry terrain but has not yet been searched for hairy braya. Original range and "possible range" were created by Joanna Wilson, Wildlife Biologist (Species at Risk), Environment and Natural Resources, Government of the Northwest Territories, in May 2013 with input from Suzanne Carriere, for the Species at Risk Committee (2012) 'Species Status Report.In October 2022, Nick Wilson and Joanna Wilson (GNWT ENR) added polygons obtained from Canadian Wildlife Service indicating the Area Containing Critical Habitat, as defined in the Recovery Strategy for Hairy Braya in Canada (ECCC 2022, available from sararegistry.gc.ca). These are the areas within which critical habitat for hairy braya 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 strategysection 6.1. Critical habitat is not necessarily the entire polygon.Updated in April 2023 by Joanna Wilson and Nick Wilson (GNWT ECC), with input from Jim Harris and Paul Sokoloff. "Possible range" was removed and Range was expanded to reflect new information from the 2022 hairy braya survey, as reflected in Wilson et al. technical survey report (in prep) and SARC 2024 status report (in prep).

Description: Point locations of sites where Nahanni Aster has been found. Locations updated November 22, 2013 by Joanna Wilson. NAHANNI ASTER (Symphyotrichum nahanniense) locations from the SARC and COSEWIC draft status reports (2013) based on the field survey in August 2012. This range has been updated in December 2019 by Bonnie Fournier, ENR, to include an additional record within the Nahanni National Park Reserve that was discovered during a 2019 survey; data provided by Melissa Beaujot, Parks Canada.

Description: Locations of globally rare plants and lichens(ranked G1 or G2 by Natureserve) in the Northwest Territories that are also ranked May Be at Risk by the NWT General Status Ranking program. Includes Drummond bluebell, Raup's willow, Banks Island alkali grass, and arctic orangebush lichen. Note that hairy braya (Braya pilosa) and Nahanni Aster (Symphotrichum nahanniense) are also ranked G1 but are not shown because they have been assessed as a Species at Risk in NWT and/or Canada and therefore have their own range maps. Developed for ENR/EC joint Species at Risk in the NWT booklet. Locations updated November 22, 2013 by Joanna Wilson. Shapefile modified to remove Nahanni Aster on February 19, 2015. One possible site for Mackenzie hairgrass (species identification requires verification) was added by Joanna Wilson on December 1, 2015. Four additional sites for Drummond Bluebell were added in November 2019.In January 2024, Mackenzie Hairgrass was removed from the dataset and points for Arctic orangebush lichen were addedby Joanna Wilson and Bonnie Fournier (GNWT ECC).DRUMMOND BLUEBELL (Mertensia drummondii) locations from: 1. Porsild AE, and Cody WJ . 1980 . Vascular Plants of Continental Northwest Territories, Canada. 2. McJannet CL, Argus GW and Cody WJ . 1995 . Rare Vascular Plants in the Northwest Territories. 3.

BANKS ISLAND ALKALI GRASS (Puccinellia banksiensis) records were drawn from ENR's NWT Virtual Herbarium in November 2013. ARCTIC ORANGEBUSH LICHEN (Seirophora aurantiaca) locations from: Sokoloff, P. & McMullin, T. 2020. Seirophora aurantiaca. The IUCN Red List of Threatened Species 2020: e.T175710010A175710692. https://dx.doi.org/10.2305/IUCN.UK.2020-3.RLTS.T175710010A175710692.en.https://www.iucnredlist.org. Downloaded on 10 November 2023. Seirophora aurantiaca is endemic to the Inuvialuit Settlement Region in the Northwest Territories, Canada, where it occurs on Banks Island, Melville Island, Victoria Island, and the Cape Parry area of the Northwest Territories mainland. This species is only known from 12 sites in the Canadian Arctic, documented by 18 herbarium collections. (Sokoloff and McMullin 2020)MACKENZIE HAIRGRASS was removed from this dataset in January 2024. A single Canadian Museum of Nature specimen 310905, collected at Old Fort Reliance on Great Slave Lake in 1927, was labeled as Deschampsia mackenzieana . However, Jeff Saarela at Canadian Museum of Nature had studied this specimen in 2018 and compared its morphology to Mackenzie hairgrass from Saskatchewan; he determined the specimen fits D. cespitosa subsp. cespitosa better. (J. Saarela, pers. comm). Therefore the best available information at this point suggests the NWT specimen is likely not Mackenzie hairgrass.
