A Case Study of Alpines in the Australian Alps
Alpine
Spatial Patterns and Dimensions * Location: Kosciuszko National Park covers 6,900 square kilometres and contains mainland Australia's highest peak, Mount Kosciuszko. The park is located in the south-eastern corner of New South Wales, 354 km, southwest of Sydney, and is contiguous with the Alpine National Park in Victoria to the south, and the Namadgi National Park in the Australian Capital Territory to the north east * Altitude: Treelines can occur over a great range of altitudes. * Size/shape continuity: the sub-alpine (snow covered in winter) and alpine areas but the truly alpine area, above the treeline,
Biophysical Interactions
The upland area of the Australian Alps is underlain by marine sediments. Then through denudation the area was worn down and dissected by different forms of weathering and erosion. Once the land was uplifted and exposed to the effects of weathering, the varying degrees of resistance to erosion offered by different rock types became important. Softer sedimentary rocks eroded far more quickly, leaving the more resistant rocks in the highest areas. Rivers and streams cut down through soft, sedimentary rocks to form deep, wide valleys and narrow gorges with spectacular waterfalls. The Australian Alps are ‘mountains with soil’ as distinct from many alpine ranges overseas which are ‘rock mountains’. Mountains on other continents are generally younger and steeper, and have been more heavily glaciated, all factors that contribute to the absence of soil. In the Australian Alps, low temperatures slow down chemical weathering of the various types of bedrock, thus slowing the formation of soil. At the higher elevations ice crystals form inside rock cracks (nivation), speeding up the mechanical shattering of rocks as the ice expands and opens up the cracks even more.
Dynamics of Weather and Climate
The climate of the Kosciuszko Alpine Area low temperature with an average mid-summer temperature often less than 10º Celsius and

    The Australian environment also has relative geological stability. The last volcanoes were active many years ago, and the last of the glaciers shrank and melted many years ago. We only had volcanoes and glaciers because of the separation of Pangaea therefore making the Continental Drift Theory. There is little geological activity to create or refresh fertile soils. The majority of Australia is very old rock therefore means that we have very poor soils and recently alluvial soils which also have poor nutrients.…

    The infamous abolitionist Frederick Douglass once said, “If there is no struggle, there is no progress.” This statement is definitely true as people can’t bring about change easily or without opposition. This declaration is personified in Paul Farmer’s story as he tries to cure the world of tuberculosis. In Mountains Beyond Mountains by Tracy Kidder, we see all the challenges and opponents that Farmer faces in attempting to bring about good, but we also see the reward of fighting the long defeat and how these challenges are active in our own lives as we try to bring about change.…

    The Rocky Mountains, which are also known as the “Rockies”, form the Continental Divide of North America. The Continental Divide is the line that determines whether water will flow to the Pacific or the Atlantic Ocean. Twenty-five percent of the water supplied to North America comes from this mountain range. The Rocky Mountains are steep and rugged mountains. They were formed from 80 to 55 million years ago. The range’s highest point, Mount Elbert is located in Colorado and sits at 14,440 feet above sea level. The varying altitude of the range influences the climate. Certain areas experience what is called the rain shadow effect. This is when an area that has…

    Although temperature and climate change are considered by many tourists to be significant factors influencing whether they visit parks (Pongkijvorasin and Chotiyaputta 2013), any advances in combating climate change requires commitment and cooperation between governments and political leaders worldwide. However, the New South Wales Park System (NPWS) is contributing through research, monitoring, community education and through enacting ‘climate care’ policies within the Kosciuszko park. The CRC sustainable tourism report (****) reveals that tourism has a range of negative environmental pressures on the alpine area, table 4 below demonstrates these issues:…

    The physiographic differences between massive and compact Australia and elongated and fragmented New Zealand are quite apparent. Much of the differences between the two countries stems from the location as it relates to the Earth 's tectonic plates. Australia lies at the center of the Australian Plate and is composed of some of the most ancient rocks on the planet. While New Zealand lies at the convergence of the Pacific and Australian Plates. It is also younger and less stable. In New Zealand, volcanoes and eruptions are common, whereas they are unknown of in Australia. The location of the two countries not only effects the volcanic activity, but also its relief. The Great Dividing Range is Australia 's highest relief. The highest of these old and eroding reliefs is Mount Kosciusko at 2230 meters (7316 ft tall). As opposed to New Zealand where its entire ranges are higher. In the Southern Alps, Mount Cook, reaches 3754 meters (12,316 ft) (Blij, 2012).…

    Relationships between springtime heat accumulation and low temperature events in the western Lower Peninsula were investigated. Sixty years (1931-1990) of daily maximum and minimum temperature data from six stations were used to calculate seasonal growing degree day (GDD) accumulation normal and extremes and their relationship to the date of last freeze at each station throughout the period. Results indicate that in spite of a wide range of individual station and year-to-year variability, both regional springtime GDD accumulation thresholds and last freeze dates are occurring earlier but the timing of GDD thresholds is changing more rapidly, resulting in a net trend toward more freezes after certain GDD thresholds are crossed and a flat or increasing amount of GDDs…

    Alpine Biome

    Similar to every other biome, the alpines have several abiotic and biotic factors. One of the main abiotic factors are temperature, which is usually below freezing and drops 10 degrees Celsius every thousand meters higher. Along with cold temperatures, there are over 100 inches of precipitation; usually in form of snow, annually, strong winds over 100 mph, and long winters. Due to these harsh abiotic factors, permafrost, or frozen soil, is present and prevents tree growth in the alpines. In addition all these abiotic factors, there are an abundance of rocks at the alpines. Furthermore, there are several biotic factors in the alpine biomes. One factor is the presence of animals. While several animals, like bighorn sheep, stay all year long, some animals migrate and hibernate in the alpines. There are few plants in the alpine biome; however, the alpines are carpeted in wildflowers, moss, and wild mushrooms.…

    One of the most heavily protected and environmentally significant areas of Australia is the Blue Mountains region. It consists of a range of unique geology and biodiversity, and as a result it was found to be a prominent region in which it would be internationally recognized and listed by UNESCO as a World Heritage Estate because of the many natural facets (UNESCO, 2009 and Commonwealth Government, 2009a). There are numerous national parks that are now regarded as part of the Greater Blue Mountains area, since the founding of the Blue Mountains National park 50 years ago (SITE). Most of these areas are in great ecological condition and are naturally vegetated (SITE)(Commonwealth Government, 1998).…

    The Australian Alps (the Alps) hold much historical and cultural value to Australians and, for this reason they are a popular tourist destination. The Alps begin in NSW with the Brindabella National Park then travel downwards through the ACT and NSW, before finishing down in Victoria’s, Baw Baw National Park. The Alps contain great geological significance through the presence of glacial lakes dotted throughout them, which provide the only evidence of glacial activity in Australia and also provide insight to the geological history of Australia.…

    With many recent studies showing that the current global rates of biodiversity loss are cause for alarm, it is important to recognize regions in which biodiversity is especially high and under threat from human expansion and climate change. The combinations of biodiversity assemblages along the Escarpment form nodes of high local endemism that have contributed towards the concept of ‘centers of endemism’ in southern Africa (Morrone 2004; Van Wyk; Smith 2001and Maggs et al., 1998).The Drakensberg Alpine Centre (DAC) is known for its diversity of plant species, and, additionally, unusually high rates of floral and faunal endemism. This region has been censured as one of the most threatened regions of global biodiversity significance, because extinction risk of both plant and animal species is intense and increasing (Burgess et al., 1997). In fact, the DAC has the highest known ratio of endemic plant and animal species worldwide, making it…
