Large wild areas are important for both nature conservation and nature-based recreation. Information on the reciprocal relationships between recreators and the environments in which they recreate can help both conservation and recreation management. We considered motivations, perceptions, environmental concerns, and social concerns among flyfishers who recreate within the Tasmanian Wilderness World Heritage Area on the Central Plateau of Tasmania, Australia. Using semi-structured interviews with 27 participants, we established that they were motivated by a love of nature, desire for experience, escapism, connection, and challenge. On the basis of motivations and attitudes, we discriminated four groups of flyfishers: “social” (those who fish with friends), “trophy” (lone fishers who are goal-oriented), “outdoor enthusiast” (those who enjoy the outdoor experience, fishing optional), and “hunter-gatherer” (those prepared to travel long distances for catch). Nonetheless, all groups perceived environmental and social problems related to fishing and visitation behaviours, from littering to climate change. Fishers perceived environmental problems included identifying exotic weeds and pests but did not specifically include trout as a pest, despite their exotic status and adverse effects on native ecosystems. However, flyfishers were aware of most of their impacts and were willing to help mitigate them. Such insight is significant for geographers and those in associated disciplines and professions seeking to manage wild protected areas.  相似文献

A New Zealand example illustrates the potential of foraging efficiency (FE) measures to inform not only on human-prey dynamics, but also to help identify situations where mobility is constrained or stimulated. Marked declines in Māori molluscan FE, coupled with increased shellfish usage, are identified over a ca. 450-year period at the coastal locality of Harataonga Beach, New Zealand. The potential effects of climate change are considered using newly available southwest Pacific multi-proxy records and temperature sensitive species, but correlations are lacking. The molluscan results signal possible restrictions on logistic and/or residential mobility in late prehistory, while evidence from the broader cultural landscape points to increasing agricultural investments and marked social competition. The Ideal Free Distribution model (IFD) is used to consider regional-scale interactions between foraging efficiency, agricultural developments, and competition, and their effects on mobility. Geographic and temporal variation in the patterning and causes of population movements is highlighted through this model, particularly differences between large game foragers in the south and populations with mixed economies in the north. In late prehistory, many northern areas including Harataonga apparently experienced reductions in the geographic scale of population movements, coupled with intensified intra-territorial mobility. The latter was an outcome of labour being widely dispatched across tribal territories, quasi-specialisation in subsistence tasks, and pooling and exchange of resources through a variety of social mechanisms which often involved population movements.  相似文献
