New Caribou Crisis – Then and Now The 13th North American Caribou Workshop Winnipeg, Manitoba, Canada 25–28 October, 2010 New caribou crisis – then and now Robert A. Ruttan Box 42, Rural Route 2, Tawatinaw, Alberta, Canada T0G 2E0 ([email protected]). Abstract: The reported decline of the Bathurst herd has caused considerable concern and has raised rumours of a “crisis” in which there is a possibility of extinction. This paper reflects on relevant lessons learned from the officially declared “crisis” of population decline in 1955/56 and a second crisis of overpopulation identified by the author a decade later. Key words: Barren ground caribou; Bathurst caribou herd; Canada; crisis, management history; population decline; resource management; traditional knowledge.

  • Relocating the Ahiarmiut from Ennadai Lake to Arviat (1950-1958)
    INALCO 2009, Proceedings of the 15th Inuit Studies Conference, Orality (Paris, 2006) Relocating the Ahiarmiut from Ennadai Lake to Arviat (1950-1958) Frédéric Laugrand Department of Anthropology and CIÉRA, Laval University (Québec, Canada) [email protected] Jarich Oosten Faculty of Social Sciences, Leiden University (Leiden, Netherlands) [email protected] David Serkoak Arviat (Nunavut, Canada) / Nunavut Sivuniksavut (Ottawa, Canada) [email protected] Introduction The relocations of the Ahiarmiut from Ennadai Lake between 1950 and 1958 are considered as a failure that caused great distress to the native population. The testimonies of the Ahiarmiut elders we recorded in Arviat all show how these relocations were experienced as a painful and terrible deportation. Scholars such as F. Tester and P. Kulchyski (1994) and A. Marcus (1995) have examined the policies of the Canadian administration which, through various agencies notably the Department of Indian and Northern Resources (DIANR) and the Royal Canadian Mounted Police (RCMP), have prepared the relocations. Even if there existed considerable differences between and within these various agencies all shared common values with respect to the necessity to assume responsibility for the well being of the native people. But the perspectives of the Ahiarmiut themselves were never discussed in any detail. So far, little attention has been paid to the lasting effects of these relocations on the Ahiarmiut population. In 2003 we organised a workshop with Ahiarmiut elders on 'Survival and Angakkuuniq' in Arviat (Nunavut). In the course of this workshop the Ahiarmiut elders Job and Eva Muqyunnik, Luke and Mary Anautalik often reflected on the events that almost fifty years ago had disrupted their lives and still affected them.

    ᐊᕙᑎᓕᕆᔨᒃᑯᑦ Department of Environment Avatiliqiyikkut Ministère de l’Environnement ESTIMATES OF WOLVERINE DENSITY FROM MARK-RECAPTURE DNA SAMPLING Napaktulik Lake, Kitikmeot Region, Nunavut 2018-2019 Final Report November 2020 Malik Awan Murray Efford John Boulanger Department of Environment Dunedin, New Zealand Integrated Ecological Research Igloolik, Nunavut Nelson, BC X0A 0L0 Napaktulik Lake wolverine density 2018-19 Summary This report presents results for a wolverine (Gulo gulo) DNA mark-recapture study conducted near Napaktulik Lake, Kitikmeot region, Nunavut, to establish baseline population abundance and density estimates for long-term regional monitoring. In addition, monitoring of the wolverine population is also important as part of predator research and management as it informs caribou management. Wolverines are listed as a species of Special Concern under the federal Species at Risk Act (SARA) and are an important cultural and economic resource traditionally harvested by Inuit. This project was done collaboratively with the Kugluktuk (Angoniatit Association) Hunters and Trappers Organization (HTO). Genetic analysis was used to identify sex and individual wolverines from DNA in hair samples collected non-invasively by a science- driven study design and logistics facilitated by local hunters. From early March through late April 2018 and 2019, the field team sampled a grid of 154 posts baited with caribou (Rangifer tarandus groenlandicus) and muskox (Ovibos moschatus) legs and scent lures. The posts were spaced in 5x5 km (25 km2) cells for three 10-day sessions within a 4,000 km2 area northwest of Napaktulik Lake. In total, 22 individual wolverines (11F:11M) were detected in 2018 and 27 wolverines in 2019 (13F:14M), including 10 individuals (6F:4M) identified first in 2018 and then recaptured in 2019.

  • Development of the Institutional Structure of the Economy of Rankin Inlet, Nunavut, Canada: Inuit Strategic Participation in Commercial Opportunities
    Development of the Institutional Structure of the Economy of Rankin Inlet, Nunavut, Canada: Inuit Strategic Participation in Commercial Opportunities By Andrew Gordon Muir A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Public Policy Carleton University Ottawa, Ontario © 2017 Andrew Gordon Muir 1 Abstract This dissertation aims to provide insight into the development of the institutional structure of the economy of Rankin Inlet, Kivalliq Region, Nunavut, Canada from its inception (1953-1957) to the period following the creation of the Territory of Nunavut in 1999. Its analysis is informed by the ideas of Karl Polanyi, who argues in The Great Transformation that Britain’s commercial economy rests upon an institutional structure erected by the state largely during the 19th Century and not, as Adam Smith famously suggested, on innate human tendencies. State interventions expanding the scope of commercial activity often undermined the viability of existing forms of non-commercial economic activity as well as the institutions upon which they were based. The British public, however, suffering from these developments successfully pressed for legislation to reduce the scope of commercial activity in their lives, in a process Polanyi refers to as the “countermovement.” Prior to the entry of Europeans to the Kivalliq Region, Inuit economic activity was non- commercial. Based on harvesting resources from the land and sea, it was governed by and played a role in regenerating societal institutions, principally the extended family. As Europeans and non-indigenous North Americans entered the region in the early 1700s in order to obtain and sell its resources on external markets, opportunities arose for Inuit to participate in commercial activity.

  • Traditional Inuit Stories by Noel K. Mcdermott a Thesis
    Unikkaaqtuat: Traditional Inuit Stories By Noel K. McDermott A thesis submitted to the Graduate Program in Cultural Studies in conformity with the requirements for the Degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada April, 2015 Copyright © Noel McDermott, 2015 Abstract Commentary on Inuit language, culture and traditions, has a long history, stretching at least as far back as 1576 when Martin Frobisher encountered Inuit on the southern shores of Baffin Island. The overwhelming majority of this vast collection of observations has been made by non-Inuit, many of whom spent limited time getting acquainted with the customs and history of their objects of study. It is not surprising, therefore, that the lack of Inuit voice in all this literature, raises serious questions about the credibility of the descriptions and the validity of the information. The Unikkaaqtuat: Traditional Inuit Stories project is presented in complete opposition to this trend and endeavours to foreground the stories, opinions and beliefs of Inuit, as told by them. The unikkaaqtuat were recorded and translated by professional Inuit translators over a five day period before an audience of Inuit students at Nunavut Arctic College, Iqaluit, Nunavut in October 2001. Eight Inuit elders from five different Nunavut communities told stories, discussed possible meanings and offered reflections on a broad range of Inuit customs and beliefs. What emerges, therefore, is not only a collection of stories, but also, a substantial body of knowledge about Inuit by Inuit, without the intervention of other voices. Editorial commentary is intentionally confined to correction of spellings and redundant repetitions.

  • TAB4A GN BN Wolverine Density in Kitikmeot for Information
    SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD FOR Information: X Decision: Issue: Estimates of wolverine density from mark-recapture DNA sampling, Napaktulik Lake, Kitikmeot Region, Nunavut, 2018- 2019. Background: • In Nunavut, the wolverine (Gulo gulo) is listed both as a furbearer and a big game species under the Nunavut Agreement and Nunavut Wildlife Act. • Wolverine is an important cultural and economic resource traditionally harvested by Inuit. • Nunavut represents the north-eastern edge of wolverine distribution in Canada. There are limited baseline data on wolverine distribution and density within Nunavut. • Currently, there are no harvest restrictions on Inuit on the harvest of wolverine in Nunavut. • The wolverine was assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as a species of Special Concern in Canada in 2014 and in 2018 was listed as Special Concern under Schedule 1 of the Species at Risk Act (SARA). While there are no associated effects on Inuit harvest in Nunavut, under SARA a national management plan must be developed within three years of being listed to prevent a species from becoming threatened or endangered. • Primary threats to wolverine persistence identified during the SARA listing process include habitat fragmentation and loss due to human development and climate change. While this is true for most parts of the species’ southern range and for western North America, the same threats are not as prevalent so far in Nunavut. • Wolverines are found in relatively low densities, have low reproductive rates with low intrinsic rate of increase, are sensitive to human disturbance and require large secure areas to maintain viable populations.
