This paper questions whether the rescaling of conservation practice in Canada to include local and Indigenous communities, NGOs, and private market-based actors represents a move away from wilderness-thinking in conservation, and what implications this might have for the future of conservation in Canada. We explore the links between Cronon's “wilderness” ethic and coloniality, racism/sexism/classism, and political economy, and the extent to which recent trends in conservation practice, such as co-management arrangements, private tourism proposals, and a shift in programming to attract a diverse public to parks, help us to move beyond the limited vision for conservation and environmentalism that the wilderness ethic provides. We interrogate the ways in which the concept of wilderness is being employed, resisted, and transformed by a multitude of actors in three parks and conservation areas across Canada. We argue that although recent developments in conservation practice help to redress some of the worrisome aspects of wilderness-thinking in parks, they also reinforce and re-emphasize problematic lines of thinking and praxis. While the wilderness character of Canadian parks has shifted a great deal since the turn of the 20th century, the wilderness ethic remains deeply embedded within conservation discourse and practice.  相似文献

The La Gila Encantada Site is located on an isolated ridge top north of Silver City, New Mexico in an area defined culturally as the Mimbres Mogollon region. The 180 m × 80 m (14400 m2) sized site was originally recorded as a dense scatter of ceramics, lithics, and ground stone along with a number of surface depressions that appear to represent pithouses. Cesium magnetometer surveys were conducted to identify hearths, pithouse boundaries, and activity areas outside of pithouses in support of archaeological investigations, and to test this instrument's ability to image these features. This paper presents a characterization of the magnetic signature of a pithouse as a magnetic high in the center caused by the central hearth, low magnetic variability along the floor of the house, and then increased magnetic variability at the pithouse boundary. This characterization was successfully confirmed for three pithouses using cesium magnetometery and archaeological excavation.  相似文献

R esidential m obility is one of the most important forces underlying changes in the social composition and physical characteristics of urban areas (Rossi 1955, p. 2). Consequently, numerous studies on residential migration have been carried out in order to comprehend this process better and thereby aid in the assessment of migration theories and in the development of appropriate models. Mobility studies have examined the characteristics of outmigration areas and households, motivations to move, satisfaction achieved through relocation, and the impact of residential changes. However, as Maher (1974) points out, previous analyses are incomplete in that they tend to focus on the demand characteristics of residential relocation and to omit the supply side of the process, the available housing stock. This study attempts to rectify this omission by considering the provision of newly constructed single-family detached housing in Windsor and the resultant migration patterns and processes through vacancy chain analysis. The demand and supply concepts of residential mobility are examined with regard to the housing multiplier generated by different locations and values of new homes, the socio-economic and demographic characteristics of households at various positions in the turnover process, the reasons for moving, and the spatial patterns of residential moves originating from new housing. In addition, by focusing on a specific form of housing the study avoids problems which may arise from aggregate level analyses of households adjusting to new housing opportunities.  相似文献

The raw materials from which stone tools are made can provide considerable information relevant to behavioral variation within a prehistoric population. By examining the stone used for tools from two different types of Late Pithouse period (A.D. 550-1000) residential sites from the Mimbres Mogollon area of Southwestern New Mexico, this paper illustrates how understanding the lithic landscape of a region provides a means to assess behavioral variation in stone procurement practices. The analysis indicates that the differences in mobility and economic pursuits between longer-term residential sites containing pit structures and a shorter-term seasonal residential site with ephemeral architecture structured the raw material procurement practices of site’s occupants. Pit structure sites were focused on agricultural pursuits and used a technology that centered on the production of informal tools fashioned from locally available raw materials. The seasonal residential site focused on wild resources and evidenced greater reliance on formal tool production using raw materials acquired from beyond the immediate vicinity of the site. Despite increasing sedentism and agricultural dependence of the region’s population, some portion of the population exercised seasonal mobility strategies and associated technological and behavioral practices more typical of hunting and gathering populations, suggesting a diverse socio-economic system within the region.  相似文献
