¶ … Climate Change in Australia's Alpine Region
The environments of entire Australia comprise of approximately 0.3% of total global land mass. The alpine region of Australia is found along the mountain ranges of southeastern, central plateau and Victoria mountain ranges. The altitudes in the alpine area vary significantly ranging from Tasmania's 1,300 m to 1,850m in South Wales (Diaz, Beniston & Bradley, 2007).
Changes in climatic conditions have diverse potential impacts on the alpine region of Australia and subalpine lives because their existence is controlled by sensitive changes in temperatures. From data about temperatures in the alpine region, there are high elevation trends thus high chances of making significant impacts on the ecological diversity. The alpine region is experiencing reduced average precipitation per annum, which leads to a reduction in the Alps of south and an increase in the Alps on North. The precipitation of the Alps depends on global warming. This includes the snow, mountain, and the rains. The impacts of global warming on fauna and flora and the functioning ecosystem are the likely visible indications of changes in climate in the Alpine (Watson, Zinyowera & Moss, 2007). In the alpine region of Australia, if the temperatures increases by 30 C, alterations will be witnessed in the area's climatic environment, including the subalpine. As a result, the scarce endemic species are lost including ground water species such as peat lands, dogs, and fens. Similarly, the losses of endemic Feld mark herb field species of alpine and snow bank are evident. In this context, an increment in temperatures leads to an increased distribution of subalpine and dominant alpine plant species (Visconti, 2009).
If changes in climate occur in the montane and subalpine regions of Australian alpine, the results are expected to benefit weeds and the exotic community. These communities would have been excluded from the region of the Alps because of extreme conditions of the environment hitting higher altitudes. Climatic changes generating dry and warm conditions...
Marketing Communications Plan for 5 Star Adventure Tours Executive Overview The International Ecotourism Society (TIES) defines ecotourism as "Responsible travel to natural areas that conserves the environment and improves the welfare of local people" (2005, p.3). Ecotourism has become the fastest growing segment of the global tourism industry, the largest sector in the world economy. Because climate is one of the main drivers of international tourism, with the majority of tourists seeking
International Regulation of Tourism in Antarctica Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how
