  • Mackenzie Highway Extension, for Structuring EIA Related Field Investigations and for Comparative Assessment of Alternate Routes
    D. Mackenzie Valley Highway Extension D.1 Consultations An initial Stakeholder Workshop was held in Norman Wells on June 8, 1998. The workshop was attended by approximately 60 stakeholders and generated considerable discussion on the need-for, and benefits-of, an all-weather road. A meeting with the Sahtu Secretariat and the Sahtu Regional Land Corporation Presidents was held on November 12, 1998. The group reviewed the Terms of Reference for Environmental Scoping and Benefit Cost Studies. The Terms of Reference were also sent to other stakeholders invited to participate on the Advisory Committee. In December the Department established an Advisory Committee for this project consisting of 25 individuals representing a wide variety of interest groups and organizations. The Department has kept this committee informed of the status of projects, and held a meeting on March 17, 1999 in Norman Wells. A list of the committee members is provided below.

  • Ancient Knowledge of Ancient Sites: Tracing Dene Identity from the Late Pleistocene and Holocene Christopher C
    11 Ancient Knowledge of Ancient Sites: Tracing Dene Identity from the Late Pleistocene and Holocene Christopher C. Hanks The oral traditions of the Dene of the Mackenzie Valley contain some intriguing clues to cul­ tural identity associated with natural events that appear to have occurred at the end of the Pleisto­ cene and during the early Holocene. The Yamoria cycle describes beaver ponds that filled the ancient basins of postglacial lakes, while other narratives appear to describe the White River ash fall of 1250 B.P. This paper examines Dene views of the past and begins the task of relating them to the archaeological and geomorphological literature in an attempt to understand the cultural per­ spectives contained in these two different views of “history.” STORIES, NOT STONE TOOLS, UNITE US The Chipewyan, Sahtu Dene, Slavey, Hare, Mountain Dene, Dogrib, and Gwich’in are the Athapaskan-speaking people of the Northwest Territories. Collectively they refer to themselves as the Dene. Their shared cultural identity spans four distinct languages and four major dialects, and is spread from Hudson's Bay to the northern Yukon. Based on archaeological culture histories, there are relatively few strands of evidence that suggest a close relationship between these groups (Clark 1991; Hanks 1994). However, by using oral traditions, the archaeological record, linguistic theories, and the geological record, it can be argued that in the distant past the ancestors of the Dene lived as one group in the mountains along the Yukon-Alaskan border (Abel 1993: 9). For some archaeologists, the Athapaskan arrival east of the Cordilleran is implied by the appearance of a microlithic technology 6000-5000 B.P.

This document represents the culmination of 15 years of land use planning with the purpose of protecting and promoting the existing and future well-being of the residents and communities of the Sahtu Settlement Area, having regard for the interests of all Canadians. From its beginnings in 1998, the Board’s early years focused on research, mapping, and public consultations to develop the goals and vision that are the foundation of the plan. From this a succession of 3 Draft Plans were written. Each Plan was submitted to a rigorous review process and refined through public meetings and written comments. This open and inclusive process was based on a balanced approach that considered how land use impacts the economic, cultural, social, and environmental values of the Sahtu Settlement Area. The current board would like to acknowledge the contributions of former board members and staff that helped us arrive at this significant milestone. Also, we would like to extend our gratitude to the numerous individuals and organizations who offered their time, energy, ideas, opinions, and suggestions that shaped the final Sahtu Land Use Plan.

Irwin, P.C., M.P., Minister of Indian Affairs and Northern Development Ottawa, 1995 QS-8507-030-EF-Al Catalogue No. R72-244/1-1995E ISBN 0-662-23939-3 © Minister of Public Works and Government Services Canada FOREWORD The Arctic Environmental Strategy (AES), announced in April 1991, is a six-year $100 million Green Plan initiative. The overall goal ofthe AES is to preserve and enhance the integrity, health, biodiversity and productivity ofour Arctic ecosystems for the benefit ofpresent and future generations. Four specific programs address some ofthe key environmental challenges: they are waste cleanup, contaminants, water management, and environment and economy integration. The programs are managed by the Northern Affairs Program ofthe Department of Indian Affairs and Northern Development (DIAND); however, there is a strong emphasis on partnerships with northern stakeholders including Native organizations, other federal departments and the territorial governments. The AES Action on Water Program specifically strives to enhance the protection ofnorthern freshwaters through improved knowledge and decision-making. Water Resources managers in the Yukon and the Northwest Territories administer this Program which focuses on freshwater aquatic ecosystems. This report is the first detailed compilation ofstudies.conducted under the AES Action on Water Program. It covers work done from 1991 to 1994. Many studies have been concluded, while others are ongoing. Although data may not be available for all studies, or results are preliminary at this time, this report presents detailed background, objectives and methodology.

  • A Freshwater Classification of the Mackenzie River Basin
    A Freshwater Classification of the Mackenzie River Basin Mike Palmer, Jonathan Higgins and Evelyn Gah Abstract The NWT Protected Areas Strategy (NWT-PAS) aims to protect special natural and cultural areas and core representative areas within each ecoregion of the NWT to help protect the NWT’s biodiversity and cultural landscapes. To date the NWT-PAS has focused its efforts primarily on terrestrial biodiversity, and has identified areas, which capture only limited aspects of freshwater biodiversity and the ecological processes necessary to sustain it. However, freshwater is a critical ecological component and physical force in the NWT. To evaluate to what extent freshwater biodiversity is represented within protected areas, the NWT-PAS Science Team completed a spatially comprehensive freshwater classification to represent broad ecological and environmental patterns. In conservation science, the underlying idea of using ecosystems, often referred to as the coarse-filter, is that by protecting the environmental features and patterns that are representative of a region, most species and natural communities, and the ecological processes that support them, will also be protected. In areas such as the NWT where species data are sparse, the coarse-filter approach is the primary tool for representing biodiversity in regional conservation planning. The classification includes the Mackenzie River Basin and several watersheds in the adjacent Queen Elizabeth drainage basin so as to cover the ecoregions identified in the NWT-PAS Mackenzie Valley Five-Year Action Plan (NWT PAS Secretariat 2003). The approach taken is a simplified version of the hierarchical classification methods outlined by Higgins and others (2005) by using abiotic attributes to characterize the dominant regional environmental patterns that influence freshwater ecosystem characteristics, and their ecological patterns and processes.

The Great Bear Lake: Its Place in History LIONEL JOHNSON1 INTRODUCTION Great Bear Lake (Fig. 1) is one of the most prominent geographic features of northern Canada. Shaped likethe missing piece of a jigsaw puzzle, with five arms radiating from a central body, it has a total area of 31,150 square kilometres - approximately the same as that of the Netherlands. It is the eighth largest, and by far the most northerly, of the world's major lakes, and probably the least productive. (Johnson 1975a). PIG. 1 Great Bear Lake and surrounding area. The Arctic Circle transects the northernmost arm of the lake, and so the sun is visible from it for 24 hours a day in June, while in mid-winter daylight lasts for only twoto three hours. In July, the mean daily maximumtemperature is 19OC, in sharp contrast to the equivalent January figure of -27OC. Warm summers and cold winters, together with a total annual precipitation of about 230 millimetres, give rise to conditions which may best be described as northern continental.
