Entrenched contests about the future of Cape York Peninsula's lands, waters and people have for long received national prominence. In the federal arena, this has climaxed with the campaign to overturn the State's declarations on wild rivers. Initially pursued as a means of influencing decisions on the determination of the government in a finely balanced federal parliament, it has been retained as an early test of the survivability of the minority Labor government. The peninsula's prominence is founded on its iconic conservation status and the continuity of Aboriginal occupance of their country, reinforced by the formidable capabilities of Indigenous and conservationist leaders. Contests are characterised by their complexity, durability and intractability. Contests are bedevilled by shifting alliances and schisms within Indigenous and conservationist constituencies. Increasingly potent is the schism between modernist/reformist/regionalist visions of Indigenous futures, forcefully presented by Noel Pearson against more traditionalist/localist visions held by many community leaderships. Other participants, notably conservationists, State politicians and bureaucracies have needed to align their policies around these contested visions. Over the last two decades, policies of State Labor governments have maintained some continuity, being pro-active on conservation goals, selectively supportive of Aboriginal advancement, necessarily passive in the determination of land claims, reactive in the resolution of land tenures and property rights, and inconsistent and ineffectual in conflict resolution and in providing leadership in shaping sustainable, multifunctional futures, attuned to the peninsula's unique challenges and potentials. 相似文献

The term ‘rewilding’ sounds as if it should have a straightforward meaning ‘to make wild again’. But in truth the term has a complex history and a host of meanings have been ascribed to it. Rewilding as a specific scientific term has its beginnings as a reference to the Wildlands Project, which was founded in 1991 and aimed to create North American core wilderness areas without human activity that would be connected by corridors. Words, however, do not stand still—they change over time and take on new meanings, while sometimes simultaneously retaining the older sense. Employing Foucault’s idea of historical genealogy, this article examines how the term rewilding was historically adopted and modified in ecological scientific discourse over the last two decades. This investigation probes what and, by extension, when and where, rewilding refers to as it has moved into various geographies across the globe. It then examines how the term has moved outside of science and been adopted by environmental activists as a plastic word. Taken as a whole, rewilding discourse seeks to erase human history and involvement with the land and flora and fauna. Such an attempted split between nature and culture may prove unproductive and even harmful. A more inclusive rewilding is a preferable strategy. 相似文献

Increasing pressures on and interest in remote and natural lands have necessitated the formulation of wilderness protection and management policies by many Australian nature conservation authorities. Planners and managers require detailed information on variation in wilderness quality and the capacity to assess the impact on wilderness of development proposals or management strategies. To meet these demands advances have been made in techniques of wilderness identification and analysis, and a national inventory of remote and natural land in Australia has been commenced. This paper reviews these developments, discussing the newly established National Wilderness Inventory and its implications for wilderness protection in Australia. 相似文献

The environmental history of the Northern Rocky Mountains was reconstructed using lake sediments from Burnt Knob Lake, Idaho, and comparing the results with those from other previously published sites in the region to understand how vegetation and fire regimes responded to large-scale climate changes during the Holocene. Vegetation reconstructions indicate parkland or alpine meadow at the end of the glacial period indicating cold-dry conditions. From 14,000 to 12,000 cal yr B.P., abundant Pinus pollen suggests warmer, moister conditions than the previous period. Most sites record the development of a forest with Pseudotsuga ca. 9500 cal yr B.P. indicating warm dry climate coincident with the summer insolation maximum. As the amplification of the seasonal cycle of insolation waned during the middle Holocene, Pseudotsuga was replaced by Pinus and Abies suggesting cool, moist conditions. The fire reconstructions show less synchroneity. In general, the sites west of the continental divide display a fire-frequency maximum around 12,000–8000 cal yr B.P., which coincides with the interval of high summer insolation and stronger-than-present subtropical high. The sites on the east side of the continental divide have the highest fire frequency ca. 6000–3500 cal yr B.P. and may be responding to a decrease in summer precipitation as monsoonal circulation weakened in the middle and late Holocene. This study demonstrated that the fire frequency of the last two decades does not exceed the historical range of variability in that periods of even higher-than-present fire frequency occurred in the past. 相似文献

Camping on Twitter, trekking in Google Street View, mountaineering on Snapchat. Wilderness is dead. Long live Wilderness 2.0. In this paper, the term “Wilderness 2.0” refers to the articulation of new media technologies, including mobile digital devices, web 2.0 and locative media, with the practice of wilderness recreation. In this new era of virtual nature, outdoor recreation occurs as much in the statusphere and blogosphere as it does in the biosphere. While much public and academic debate about Wilderness 2.0 has focused on the extent to which new media technologies connect people to, or disconnect them from, nature, this paper argues that wilderness is not a static and essential reality that can simply be connected to or disconnected from, but a social construct that is continually re-created in different cultural contexts. In this sense, Wilderness 2.0 reflects the re-creation of a new ontology of wilderness as DigiPlace: an augmented reality that blurs the lines between the “actual” and the “virtual.” Moreover, Wilderness 2.0 does not simply refer to the creation of a new ontology of wilderness, but the incorporation of outdoor recreation into the political economy of the web 2.0. In the context of Wilderness 2.0, outdoor recreation is increasingly exploited as a form of virtual labour. Thus, despite being associated with a discourse of “sharing” and “connecting to nature,” Wilderness 2.0 is, above all else, a nature that capital can see. 相似文献

Migratory and resident birds were censused, and their habitat use quantified, during three fall migration seasons in Georgia, USA. The suburban study site was a large cemetery with patches of lawn and shade trees, deciduous brush, mature hardwood forest, and an open pine grove. The frequency of use of different cover types, perch heights, and perch substrates was measured for five resident and four migrant species. All of the migrants used narrower subsets of the available habitats than most or all of the resident species. Three migrants also used habitats that were relatively unused by other species at the site. The frequency of use of different patches of vegetation was measured for seven residents and five migrants. Four of the migrants used narrow subsets of the available patches that were used relatively infrequently by other species at the site. Although three of the migrants heavily used a cover type (deciduous brush) that might be available at most stop-over sites, the red-eyed vireo heavily used ornamental magnolia trees which are probably unavailable at most sites. The narrow habitat and patch use of migrants might reflect reduced intraspecific competition because of the small numbers of each species using the site simultaneously. [Key words: bird ecology, foraging behavior, habitat, migrant birds, resident birds, Georgia.] 相似文献

This paper offers a critique of politically dominant Eurocentric notions of culture and nature in Australia. In particular, it interrogates Eurocentric concepts of animals, wildlife and management, and seeks to unsettle these concepts by considering some of the diverse ways in which indigenous people in Australia know country, animals and wilderness. Using the metaphor of Eurocentric ontology in a hall of mirrors, the paper argues that Eurocentric claims of universalism for naturalised discourses that assume the adequacy of a nature-culture binary form a very fragile circular argument. Self-justifying the imposition and assertion of Eurocentric concepts and practices is a mechanistic reflection of the particular terms of reference set by Eurocentric knowledges and a denial of multiple ways of knowing. The dangers this presents are illustrated by examining how concepts and practices underlying wildlife management have self-justified (continuing) colonising processes in Australia. Finally, the paper attempts to open up spaces that address these dangers. Situated engagement is introduced as an approach which could shatter the hall of mirrors--by clearly embodying and emplacing all thought and action, universalised boundaries can be recognised and breached and new possibilities imagined and realised. 相似文献
