Barren-Ground Caribou (Rangifer Tarandus Groenlandicus) Assessment Summary – May 2004 Common name Barren-ground caribou (Dolphin and Union population) Scientific name Rangifer tarandus groenlandicus Status Special Concern Reason for designation This population of caribou is endemic to Canada. Once thought to be extinct, numbers have recovered to perhaps a quarter of the population historic size. They have not been censused since 1997 and are subject to a high rate of harvest, whose sustainability is questioned by some. They migrate between the mainland and Victoria Island and climate warming or increased shipping may make the ice crossing more dangerous. The population, however, increased substantially over the last three generations and was estimated at about 28,000 in 1997. Occurrence Northwest Territories, Nunavut Status history The original designation considered a single unit that included Peary caribou, Rangifer tarandus pearyi, and what is now known as the Dolphin and Union population of the barren-ground caribou, Rangifer tarandus groenlandicus. It was assigned a status of Threatened in April 1979. Split to allow designation of three separate populations in 1991: Banks Island (Endangered), High Arctic (Endangered) and Low Arctic (Threatened) populations. In May 2004 all three population designations were de-activated, and the Peary caribou, Rangifer tarandus pearyi, was assessed separately from the barren-ground caribou (Dolphin and Union population), Rangifer tarandus groenlandicus. The Dolphin and Union population is composed of a portion of the former “Low Arctic population”, and it was designated Special Concern in May 2004. Last assessment based on an update status report. iv .

  • Seasonal Changes in the Composition of the Diets of Peary Caribou and Muskoxen on Banks Island
    Seasonal changes in the composition of the diets of Peary caribou and muskoxen on Banks Island Nicholas C. Larter & John A. Nagy Caribou and muskoxen are the only ungulate species occupying Arctic tundra environments. We analysed plant fragments found in fresh (< 4 hr old) samples of faecal material to determine the diets of Peary caribou (Rangifer tarandus pearyi) and muskoxen (Ovibos moschatus) on Banks Island, Canada. Willow was a major component of the diets of both ani- mals, dominating the caribou diet during summer and representing sub- stantial proportions of the muskoxen diet during at least seven months of the year. The diet of caribou was more diverse than that of muskoxen and was dominated by sedge, willow (Salix arctica), legume (Astragalus spp., Oxytropis spp.) and Dryas integrifolia. The diet of muskoxen was domi- nated by sedge and willow. There was substantial overlap (up to 70 %) in the diets of these herbivores with the similarity more pronounced in areas of high muskox density (ca. 1.65 animals/km2). We discuss herbivore diets in relation to foraging behaviour and forage availability. N. C.

There were a total of 2,782 adult muskox (and 139 calves) seen on transect in all four stratums surveyed yielding a population estimate of 14,547±2,593 (95% confident interval) non-calf muskox for the entire area surveyed.

  • Peary Caribou Management Plan Without Full Involvement of Both Arctic Bay and Pond Inlet
    SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD (NWMB) Regular Meeting No. RM 002- 2018 FOR Information: ☐ Decision: ☒ Issue: Delay or Suspension of the NWMB Public Hearing Processes for “Management Plan for Peary Caribou in Nunavut”, and All Peary Caribou TAHs and Moratoriums in Qikiqtaaluk Region Background: Since the 1960s, Resolute Bay and Grise Fiord have been effectively self-managing Peary caribou harvests on the High Arctic islands within their resource use areas. These communities have over 50 years of Peary caribou management expertise, which they have adjusted as needed with many population fluctuations and changes in distributions of Peary caribou. In their harvesting areas, no caribou populations have been depleted due to harvesting under the communities’ careful and wise management. The QWB supports the HTOs in continuing their long legacy of Peary caribou management based mainly on Inuit Qaujimajatuqangit. Nunavut’s Department of Environment (DoE) has developed a Peary caribou management plan without full involvement of both Arctic Bay and Pond Inlet. During February 2018, DoE consulted about the proposed plan with the HTO Boards in Grise Fiord and Resolute Bay, but not in Arctic Bay and Pond Inlet. Public meetings were not held in Grise Fiord and Resolute Bay, but the HTO Boards did inform DoE that the public had to be consulted before decisions could be made. Inuit in the communities do not understand the implications of the proposed Plan. The communities want to be able to continue their proven community-based management of Peary caribou. These effective mechanisms have not been explicitly recognized and enabled in the current draft of the DoE plan.

This document reports on interim progress and provides maps of Peary caribou and muskox distribution. Data analysis, using program Distance 5.0, will provide density and abundance estimates for Peary caribou and muskoxen. Results are being finalized and will be detailed in a comprehensive Government of Nunavut Report. Acknowledgements: Funding for this study was provided by the Department of Environment, PCSP and the NWMB. Support and direction from the Resolute Bay and Grise Fiord HTOs has been invaluable. Much thanks to Grigor Hope, Mitch Campbell, Tom Kiguktak, John Innus, and Brian Dooley, for their dedication throughout our field program. Thanks to Tabitha Mullin for providing field equipment and advice. We are especially thankful to PCSP for all their equipment and logistical support, particularly, Mike Kristjanson and Barry Hough.

  • Page 1 of 2 SUBMISSION to the NUNAVUT WILDLIFE
    SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD FOR Information: Decision: X Issue: Downlisting of Peary Caribou from Endangered to Threatened. Background: In October 2016 the Committee on the Status of Wildlife in Canada (COSEWIC) provided a re‐ assessment of Peary Caribou to the federal Minister of the Environment. This begins the formal listing process under the federal Species at Risk Act. Peary Caribou, which are currently listed under the federal SARA as Endangered, have been re‐assessed by COSEWIC in a lower risk category as Threatened. A recovery strategy is required for both Endangered and Threatened species. If Peary Caribou are downlisted under the federal SARA, a recovery strategy will still be required and it will not affect the current recovery strategy development process currently underway for Peary Caribou GN - Morgan Anderson Community consultations on the proposed downlisting of Peary Caribou were held with hunters and trappers organizations (HTOs) and regional wildlife boards in the range of Peary Caribou between June and August 2017. Organizations were asked to provide their formal position on the proposed downlisting and with any other comments, concerns or information that they feel should be considered. Consultation packages, in Inuktitut and English, were sent by mail and email. They included: a letter, information on the assessment and a questionnaire/response form. Follow‐up calls to the HTOs and RWBs were made on September 27, 2017. Results of Consultation: Kitikmeot Regional Wildlife Board No response

We opted to diverge from the previous costal survey methods (conducted in fall 1997, 2007, 2015, and 2018) for three main reasons. Firstly, local hunters from the communities of Kugluktuk, Cambridge Bay, and Ulukhaktok believed current estimates of abundance, and DU caribou telemetry locations, were not representative of observed changes in DU caribou seasonal range use and migratory behaviors in recent years. Communities also reported recent declines but requested a larger survey effort to ensure changes in caribou behavior were not invalidating the coastal survey method.
