Solitudes in Shared Spaces: Aboriginal and EuroCanadian Anglicans in the Yukon and the Northwest Territories in the Post-Residential School Era

Cheryl, Gaver 16 May 2011 (has links)
This thesis examines the current relationship between Aboriginal and EuroCanadian Anglicans in the Northwest Territories and the Yukon as they seek to move beyond past hurts into a more positive future. After three field trips to Canada's North, visiting seven communities and interviewing seventy-nine individuals, complemented by archival research, I realized the dominant narrative based on a colonialism process linking residential schools, Christian Churches and federal government in a concerted effort to deliberately destroy Aboriginal peoples, cultures, and nations was not adequate to explain what happened in the North or the relationship that exists today. Two other narratives finally emerged from my research. The dominant narrative on its own represents a simplistic, one-dimensional caricature of Northern history and relationships. The second narrative reveals a more complex and nuanced history of relationships in Canada's North with missionaries and residential school officials sometimes operating out of their ethnocentric and colonialistic worldview to assimilate Aboriginal peoples to the dominant society and sometimes acting to preserve Aboriginal ways, including Aboriginal languages and cultures, and sometimes protesting and challenging colonialist policies geared to destroying Aboriginal self-sufficiency and seizing Aboriginal lands. The third narrative is more subtle but also reflects the most devastating process. It builds on what has already been acknowledged by so many: loss of culture. Instead of seeing culture as only tangible components and traditional ways of living, however, the third narrative focuses on a more deep-seated understanding of culture as the process informing how one organizes and understands the world in which one lives. Even when physical and sexual abuse did not occur, and even when traditional skills were affirmed, the cultural collisions that occurred in Anglican residential schools in Canada's North shattered children's understanding of reality itself. While the Anglican Church is moving beyond colonialism in many ways - affirming Aboriginal values and empowering Aboriginal people within the Anglican community, it nevertheless has yet to deal with the cultural divide that continues to be found in their congregations and continues to affect their relationship in Northern communities where Aboriginal and EuroCanadian people worship together yet remain separate.

The biotic and abiotic interactions influencing organochlorine contaminants in temporal trends (1992-2003) of three Yukon lakes: focus on Lake Laberge

Ryan, Michael J. 29 March 2007 (has links)
Periodic monitoring of contaminant levels in fish from the Yukon Territory indicated that organochlorine (OC) contaminants had rapidly declined since the early 1990s. This study examined OC concentrations, including chlordane (sigma-CHL), sigma-DDT, hexachlorocyclohexane (sigma-HCH), toxaphene (sigma-CHB), sigma-PCB and chlorinated benzenes (sigma-CBz) in sentinel fish (species of consistent annual observation and collection) from two Yukon lakes (Kusawa, Quiet), and from the aquatic food web of a focus lake (Lake Laberge) across several temporal points between 1993 and 2003. OC analysis and phytoplankton counts from dated sediment cores as well as climate data were also collected. Population, morphological (length, weight, age), biochemical (lipid content, delta-13C, delta-15N) and OC contaminant data for fish and invertebrates (zooplankton, snails, clams) were reviewed to elucidate the primary causes for these OC declines. Although some spatial differences in contaminant levels exist between the Yukon lakes, OC concentrations were declining for lake trout in all three lakes, with declines also noted for burbot from Lake Laberge. Several other fish species as well as zooplankton from Lake Laberge exhibited decreases in contaminant levels except northern pike, which registered consistently higher levels from 1993 to 2001. There was no evidence to support the hypotheses of changes in fish trophic levels or food sources with the exception of burbot, which marginally decreased, and northern pike, which climbed a half trophic level. Through OC flux analysis in dated sediments, the hypothesis that declines in abiotic deposition affected the contaminant levels in the food web was also negated. The closure of the Lake Laberge commercial fishery resulted in faster fish growth and larger fish populations, which are contributing to biomass dilution of OC concentrations, higher OC biomagnification factors for some species and likely changes in predator-prey interactions as resource competition increases. The large ratio of OC decreases in the lower vs. higher trophic levels of Lake Laberge have increased food web magnification factors (FWMF) for all six OC groups. It is also suspected that above-average temperatures and below-average precipitation in the lower Yukon region over the 1990s may have contributed towards an increase in lake primary production resulting in biomass dilution of contaminants in zooplankton for all three study lakes. Concurrently, shifts in the Lake Laberge zooplankton community, from climate fluctuations or increased fish predation, have gone from an abundance of Cyclops scutifer in 1993 to dominance by Diaptomus pribilofensis in 2001, although sample sites were limited. Characteristics specific to each species (e.g. body size, composition and metabolism) likely play a role in the significant OC declines measured in zooplankton. Fluctuations in population dynamics, species characteristics and OC contaminant concentrations in the Lake Laberge ecosystem may continue for several years to come. Sentinel species such as lake trout, burbot, whitefish, cisco and plankton should continue to be monitored in all three Yukon lakes for future temporal correlations with contaminants or climate change. / May 2006

A Geochemical Characterization of a Cold-Water Acid Rock Drainage Stream Emanating From the Zn-Pb XY-deposit, Howard's Pass, Yukon Territory, Canada

Feige, Kristen B. 08 February 2011 (has links)
An acid rock drainage (ARD) stream emanating from the Zn-Pb XY-deposit in the Yukon Territory was examined in order to evaluate the physico-chemical and geochemical processes governing the distribution of dissolved elements from the creek. The creek showed very high concentrations of metals (300 mg/L Fe, 500 mg/L Zn, 15 000 µg/L Ni, 1300 µg/L Cu and 4500 µg/L Cd), low water temperatures (1 – 12°C) and was acidic to moderately acidic (pH 3.1 – 5.0). It was found that this stream experienced a strong seasonal evolution, with increased sulphate and metal concentrations and decreased pH over the course of the summer. The mineral precipitates that formed under low pH conditions were a mixture of schwertmannite, goethite, jarosite and barite, while those that formed under moderately acidic conditions were a mixture of jurbanite, hydrobasaluminite, gibbsite and an X-ray amorphous Al-sulphate phase. Most of the mineral precipitates were of inorganic origin, although microbes may have played a role in mineral formation and trace metal sequestration in some of the precipitates. All of the mineral precipitates contained anomalous concentrations of trace elements (up to 1.5 % wt Zn) and showed a seasonal evolution in their mineralogy, both of which were determined to be a function of the pH and prevailing geochemical conditions. The geochemistry of the ARD creek draining the XY-deposit was compared to another ARD creek in the area that was likely draining shales. The two creeks were compared in order to determine if ARD geochemical characteristics can be used as a tool for the mineral exploration industry.

Conservation on a Regional Scale: Assessing the Yellowstone to Yukon Conservation Initiative

McGregor, Tanya January 2003 (has links)
Trends in environmental and resource management point to a more collaborative, integrated and regional approach, discussed in terms of concepts such as ecosystem management and collaborative planning. Such an approach has the potential to address some of the shortfalls previously encountered in environmental management and nature conservation, and has been the focus of considerable discussion in the literature. While a number of efforts are underway, there remains a need to identify how a regional approach can best be undertaken in practice. This research assessed the Yellowstone to Yukon Conservation Initiative (Y2Y), a recent regional conservation initiative in western North America, which has been the focus of considerable attention in the conservation community. This research assessed the strengths and limitations of the Yellowstone to Yukon Conservation Initiative in terms of its contribution to regional conservation planning, aiming to gain an understanding of implications for similar regional conservation efforts. Literature relating to regional conservation was examined to derive principles for effective regional conservation planning, as a basis for comparison with Y2Y. Drawing from needs of ecosystem management, collaborative planning, and related concepts, criteria were developed to assess the formative stages of a regional approach, emphasising capacity building measures and preconditions for success. In order to assess the strengths and limitations of Y2Y at a regional scale, this research attempted to obtain an understanding of how the Y2Y initiative was perceived by multiple stakeholders in regional conservation, as a basis for interpreting multi-stakeholder involvement and buy-in. A series of semi-structured interviews were conducted with a diverse range of individuals involved (directly and indirectly) in conservation planning, in two communities in the Y2Y region, Canmore and Crowsnest Pass, Alberta. These communities were selected to provide a degree of representation of areas within the Alberta portion of the Y2Y region. Perceptions of successes and obstacles of the initiative were compared with the criteria for effective regional conservation planning. Findings pointed to three recurring themes that influenced the initiative's ability to meet the criteria. These were the need to address both ecological and social components of conservation, the need to include diverse participants, and the need to operate at regional and local scales. These themes are consistent with limitations of traditional conservation and management practices critiqued in the literature, and suggest some substantial obstacles for employing a truly collaborative regional approach to conservation. Reflecting on the findings revealed that the Y2Y initiative was primarily understood as a vision. The Y2Y vision is one that has garnered a great deal of support and momentum, although there is a need to progress beyond the vision to address its potential and apply the ideals it puts forward. Recommendations of this study for Y2Y and similar initiatives included the need to build partnerships with more diverse groups, and the need for the Y2Y vision to be promoted in terms of some tangible, more specific goals. This study identified a need for biophysical, social science, and stakeholder information needs to be assessed and prioritised at the start of an initiative. Additionally, a vision was recognised as an effective rallying point from which to develop a regional conservation planning initiative.

Mortality in the Yukon: Post-harvest Effects on Structural Retention

Smith, Fraser 15 February 2010 (has links)
Structural retention harvesting represents one of the most important recent silvicultural innovations and is widely practiced in the harvesting of mature boreal stands. Following structural retention harvests, mortality of retained trees is often dramatically elevated compared to pre-harvest stands. I examined tree mortality following structural retention harvests in the southeastern Yukon Territory, using dendrochronological techniques to quantify annual mortality. I estimated integrated losses in the first five years to be at least 17.3% of retained stems. Analysis of mortality type showed that windthrow was the most important post-harvest mortality mechanism. This study represents the first analysis of mortality responses following structural retention harvests in the northern extent of operational forestry in Canada. Rates of post-harvest tree mortality observed in this study are among the highest reported to date from managed Canadian boreal forests, indicating that greater attention must be given to post-harvest stand responses if sustainable forestry practices are desired.

Assessing Yukon's current approach to regional land use planning : perspectives from the North Yukon planning process

Leach, Amy Joan 20 June 2011 (has links)
Regional land use planning in the Yukon has a long and unfortunate history of failed efforts. Under Chapter 11 of the Yukon First Nations Umbrella Final Agreement, a new process for planning has been in place since 1993. Through qualitative, interview-based research, I explore possible factors that either hinder or facilitate successful planning. I used the North Yukon regional land use planning effort as a case study example of the first plan to be successfully approved in Yukon history. A number of challenges resulting from poorly defined roles and responsibilities caused notable struggles and conflict throughout the process, but fortunately, strong political support and micro and meso – level organization, combined with a solid team of skilled and dedicated people, allowed the process to ultimately succeed. Lessons learned and recommendations for future regional planning initiatives are discussed.

Unveiling Yukon intergovernmental communication

Buckway, Bev J. 11 July 2011 (has links)
Yukon is unique in Canada for its four orders of government—federal, territorial, First Nation and municipal. Determining the differences in communication characteristics, strategies, mechanisms, and processes of the governments can assist with effective communication among them, leading to new opportunities. Interviews with 20 participants representing elected, appointed, and senior staff positions from four orders of government extracted thoughts and experiences on intergovernmental communication through the phenomenological tradition. Strong internal communication complements effective external communication; government individuals do not understand all the structures and processes of other governments, but instead make assumptions that can create friction and conflict while a sincere desire to improve communication is evident. Lack of time, capacity, and knowledge are contributing factors to poor communication efforts. Interpersonal communication is the key to establishing stronger relationships and rebuilding trust. Recent self-government status for Yukon‘s First Nations provides opportunities for expansion and inclusiveness of intergovernmental communication. Key words: intergovernmental communication, interpersonal communication, Yukon governments, relationships.
