The Thermal State of Permafrost in Canada – Results from the International Polar Year
The Thermal State of Permafrost in Canada – Results from the International Polar Year Sharon L. Smith 1, Antoni G. Lewkowicz 2, Christopher R. Burn 3, Michel Allard 4 & Jennifer Throop 2 1Geological Survey of Canada, Natural Resources Canada, Ottawa, Ontario, Canada 2Department of Geography, University of Ottawa, Ottawa, Ontario, Canada 3Department of Geography and Environmental Studies, Carleton University, Ottawa, Ontario, Canada 4Centre d’études nordiques, Université Laval, Ste-Foy, Québec, Canada ABSTRACT A snapshot of permafrost thermal state in northern Canada during the International Polar Year was developed with ground temperature measurements from about 170 boreholes. The measurements span a wide range of ecoclimate and geological conditions and are at various elevations. Ground temperatures within the discontinuous permafrost zone are generally above -2°C and range to as low as -15°C in the continuous zone. Permafrost temperatures have generally increased across northern Canada for the past several decades, with greater warming rates occurring north of tree line. Consequently the spatial diversity of permafrost thermal conditions is decreasing over time. RÉSUMÉ Un instantané de l’état thermique du pergélisol dans le nord du Canada au cours de l’Année polaire internationale a été élaboré en utilisant les mesures des températures au sol obtenues d’environ 170 puits. Les mesures couvraient une vaste gamme de conditions écoclimatiques et géologiques et diverses élévations. Les températures au sol au sein de la zone discontinue de pergélisol étaient généralement supérieures à -2°C et descendaient jusqu’à -15°C dans la zone continue. Les températures du pergélisol ont généralement augmenté dans tout le nord du Canada au cours des dernières décennies, les taux de réchauffement les plus marqués étant survenus au nord de la ligne des arbres. -
I. 1. the Influence of Permafrost on Northern Development
I. 1. THE INFLUENCE OF PERMAFROST ON NORTHERN DEVELOPMENT INTRODUCTION The expansion of settlement from man's early home in the fertile, friendly and protected river valleys of the Middle East has been marked by conquest of one natural obstacle after another. Broad seas, hot, dry deserts, mountain ranges and dense forests each in their turn arrested his progress until new techniques were devised and perfected, and became common knowledge. His invasion of the tropical rainforests was delayed by diseases, and his ventures into the far north - what Stefansson has termed "The .Northward Course of Empire" (1) - were handicapped by severe cold and snow, and by the heavy ice which impeded and damaged his ships. In his long and frequently frustrated efforts to make a home in even the remotest parts of the earth, man has encountered, and eventually learned to deal with, an enormous variety of natural hazards. Perennially frozen ground in the polar regions is one of his most recent natural obstacles. It has become of major importance only in the past few decades, although its existence has long been known. Alexander Mackenzie mentioned it and Jules Verne wrote a novel (2) based in part on it, while the quick-frozen mammoths of Siberia have been a cause of wonder for generations. How was it that such a widespread phenomenon, covering about one-half of Canada and almost as great a proportion of the Soviet Union, should nevertheless have attracted so little attention that until a few years ago it even lacked a commonly accepted English name and is only now being honoured in Canada by a national symposium ? The world population map demonstrates that man has as yet barely reached in any numbers the southern limit of that one-fifth of the land surface underlain by permafrost. -
Celebrating 100 Years of Migratory Bird Conservation

Feature Article Celebrating 100 Years of Canada’s Boreal Forest Wetlands Migratory Bird Conservation 100th Anniversary of the Part 1: Canada Migratory Bird Treaty To honor the 100th anniversary of the Migratory Bird Part 1: Canada Treaty, this year’s WWG newsletters will highlight wetlands of international importance across North America! ASWM Update The Migratory Bird Treaty in Canada was enacted with the passage of the Migratory Birds Convention Act (MBCA) during 1917; subsequent updates occurred during TWS Action Center 1994 and 2005. It is the responsibility of Environment and Climate Change USFWS Resource Protection Canada to develop and implement policies and regulations to ensure the protection Act of migratory birds, their eggs and their nests. Check out their webiste for more information about the MBCA in Canada. IUCN Call for Articles Canada’s diverse habitats support about 450 species of native birds, the majority of Wetlands at Risk which are protected under the MBCA. Through bird-watching, and subsistence and recreational huning, native birds are an integral part of Canada’s heritage. Migratory WWG News birds also play important ecological and biological roles in the environment. A recent Call for nominations report, The State of Canada’s Birds 2012 shows that bird populations in Canada are Student award changing.

The Rise and Decline of Hybrid (Metis) Societies on the Frontier of Western Canada and Southern Africa
THE RISE AND DECLINE OF HYBRID (METIS) SOCIETIES ON THE FRONTIER OF WESTERN CANADA AND SOUTHERN AFRICA ALVIN KIENETZ, P.O. Box 402, The Pas, Manitoba, Canada, R9A 1K5. ABSTRACT/RESUME A comparison of the development of the Metis in Canada and similar peoples in Southern Africa reveals some remarkable similarities between the two groups. The existence of these parallels suggests that a more extensive comparative study of peoples of mixed race throughout the world would be of value. Une comparaison de l'évolution des Métis au Canada et de celle de certains peuples similaires dans le Sud africain révèle des ressemblances frappantes entre les deux groupes. Ce parallèle suggère qu'une étude comparative plus complete des peuples de race mixte dans le monde entier présenterait une valeur incontestable. THE CANADIANJOURNAL OF NATIVE STUDIES Ill, 1(1983): 3.21 4 ALVIN KIENETZ The comparative study of the "frontier" as a historical-geographical phe- nomenon appears to have, or have had, two main traditions: the first of these, the purpose of which is ultimately practical (i.e. applied geography) is found in the largely pre-World I pioneer settlement studies of Bowman and others (1937). The other tradition involves attempts to apply the "frontier thesis" of Frederick Jackson Turner to other historical settlement frontiers(c.f.Wyman and Kroeber, 1957). What both of these traditions have in common is that they focus almost entirely on the advancing, colonizing culture; the retreating, native groups that are being colonized, or - better - colonialized, 1 are hardly even mentioned. 2 Only relatively recently have scholars begun to give due recognition to the roles and contributions of native or aboriginal societies on the frontier. -

Inuit and their Chukchi neighbors have always been highly mobile, but the imposition of three international borders in the region constrained travel, trade, hunting, and resource stewardship among neighboring groups. Colonization, assimilation, and enforcement of national laws further separated those even from the same family. In recent decades, Inuit and Chukchi have re-established many ties across those boundaries, making it easier to travel and trade with one another and to create new institutions of environmental management. To introduce Indigenous perspectives into the discussion of transboundary maritime water connections in the Arctic, this paper presents personal descriptions of what those connections mean to people who live and work along and across each of the national frontiers within the region: Russia–U.S., U.S.–Canada, and Canada–Greenland. -

In this study, we used a meta-analytic approach to quantify yields of alternative white (Picea glauca (Moench) Voss) and hybrid spruce (Picea engelmannii Parry ex Engelmann x Picea glauca (Moench) Voss) stocks across planting sites in the boreal and hemiboreal forests of Canada. We extracted meta-data from published tree improvement program results for five Canadian provinces covering 38 planting sites and 330 white and hybrid spruce provenances. Using these meta-data and a random-coefficients nonlinear mixed-effects modelling approach, we modelled average height over time trajectories for varying planting site characteristics, as well as climate transfer distances between planting sites and provenances. -

Northern Connections
NORTHERN CONNECTIONS A Multi-Modal Transportation Blueprint for the North FEBRUARY 2008 Government of Yukon Photos and maps courtesy of: ALCAN RaiLink Inc. Government of British Columbia Government of Northwest Territories Government of Nunavut Government of Yukon Designed and printed in Canada’s North Copyright February 2008 ISBN: 1-55362-342-8 MESSAGE FROM MINISTERS It is our pleasure to present Northern Connections: A Multi-Modal Transportation Blueprint for the North, a pan-territorial perspective on the transportation needs of Northern Canada. This paper discusses a vision for the development of northern transportation infrastructure in the context of a current massive infrastructure decit. Research has proven that modern transportation infrastructure brings immense benets. The northern transportation system of the future must support economic development, connect northern communities to each other and to the south, and provide for enhanced sovereignty and security in Canada’s north. This document complements a comprehensive national transportation strategy – Looking to the Future: A Plan for Investing in Canada’s Transportation System – released under the auspices of the Council of the Federation in December 2005. The three territories support the details contained in Looking to the Future that call for a secure, long-term funding framework for transportation infrastructure that will benet all Canadians. Equally important, northern territories stress that this national strategy – and any subsequent funding mechanisms that follow – must account for unique northern needs and priorities, which would be largely overlooked using nation-wide criteria only. This paper is also consistent with A Northern Vision: A Stronger North and a Better Canada, the May 2007 release of a pan-territorial vision for the north.
