Kosciuszko National Park
The Kosciuszko National Park // is a 6,900-square-kilometre (2,700 sq mi) national park and contains mainland Australia's highest peak, Mount Kosciuszko, for which it is named, and Cabramurra the highest town in Australia. Its borders contain a mix of rugged mountains and wilderness, characterised by an alpine climate, which makes it popular with recreational skiers and bushwalkers.
The park is located in the southeastern corner of New South Wales, 354 km (220 mi) 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 northeast. The larger towns of Cooma, Tumut and Jindabyne lie just outside and service the park.
The Australian Alps Bioregion was initially discovered by two First People Aboriginal groups. The Walgalu people occupied the northern part of what is today named the Kosciuszko National Park, while the Ngarigo people lived in the region around the highlands.
Multiple Aboriginal groups in the southern part of NSW gathered in the Australian Alps Bioregion in the summer on an annual pilgrimage to the Bogong and Snowy Mountains. Here, the men participated in a feast of bogong moths (Agrotis infusa) that were found on the rocky outcrops of the mountains.
The area was explored by Europeans in 1835, and in 1840, Edmund Strzelecki ascended Mount Kosciuszko and re-named it after a Polish patriot. High-country stockmen followed, using the Snowy Mountains for grazing during the summer months. Banjo Paterson's famous poem The Man From Snowy River recalls this era. The cattle graziers have left a legacy of mountain huts scattered across the area. Today these huts are maintained by the National Parks and Wildlife Service or volunteer organisations like the Kosciuszko Huts Association. In the 19th century, gold was mined on the high plains near Kiandra. At its height, this community had a population of about 4,000 people, and ran 14 hotels. It was here that Skiing in Australia commenced around 1861. Since the last resident left in 1974, Kiandra has become a ghost town of ruins and abandoned diggings. In the 20th century, the focus of Skiing in New South Wales shifted south closer to the Kosciuszko Main Range.
The Kosciuszko National Park came into existence as the National Chase Snowy Mountains on 5 December 1906. In April 1944, following the passage of the Kosciusko State Park Act, the Kosciusko State Park was proclaimed. It then became the Kosciuszko National Park in 1967. The name was misspelt as Kosciusko until 1997.
The construction of the Snowy Mountains Scheme between 1949–74 saw much of the area explored, brought improvements to roads and resulted in the construction of several dams and tunnels across the Park in one of the world's largest engineering achievements
Kosciuszko National Park has a number of heritage-listed sites, including:
The higher regions of the park experience an alpine climate which is unusual on mainland Australia. However, only the peaks of the main range are subject to consistent heavy winter snow. The climate station at Charlotte Pass recorded Australia's lowest temperature of −23 °C (−9 °F) on 28 June 1994.
During the last ice age, which peaked about 20,000 years ago in the Pleistocene epoch, the highest peaks of the main range near Mount Kosciuszko experienced a climate which favoured the formation of glaciers, evidence of which can still be seen today. Cirques moraines, tarn lakes, roche moutonnées and other glacial features can all be seen in the area. Lake Cootapatamba, which was formed by an ice spilling from Mount Kosciuszko's southern flank, is the highest lake on the Australian mainland. Lake Albina, Club Lake, Blue Lake, and Hedley Tarn also have glacial origins.
There is some disagreement as to exactly how widespread Pleistocene glaciation was on the main range, and little or no evidence from earlier glacial periods exists. The 'David Moraine', a one-kilometre-long ridge running across Spencers Creek valley seems to indicate a larger glacier existed in this area at some time, however the glacial origin of this feature is disputed.
There is evidence of periglacial activity in the area. Solifluction appears to have created terraces on the northwest flank of Mount Northcote. Frost heave is also a significant agent of soil erosion in the Kosciuszko Area.
The Kosciuszko National Park covers a variety of climatic regions which support several distinct ecosystems.
That which is most closely identified with the park, the alpine area above the tree line, is one of the most fragile and covers the smallest area. This area is a patchwork of alpine heaths, herbfields, feldmarks, bogs and fens. The windswept feldmark ecotope is endemic to the alpine region, and covers a mere 300,000 m2 (3,200,000 sq ft). It is most vulnerable to the wandering footsteps of unmindful tourists.
Nine separate wilderness zones have been identified in the latest management scheme. These include the Indi, Byadbo, Pilot, Jagungal, Bogong Peaks, Goobarragandra, Western Falls, Bramina and Bimberi wilderness areas.
Many rare or threatened plant and animal species occur within the boundaries of the park.
The park is home to one of Australia's most threatened species: the corroboree frog. The endangered mountain pygmy possum and the more common dusky antechinus are located in the high country of the park.
There are also significant populations of feral animals in the park, including brumbies or wild horses. Park authorities have coordinated their culling and relocation, leading to public controversy over how to reduce their numbers. The actual number of horses within the park is also difficult to ascertain with estimates ranging from 1700 in 2008 increasing by 300 each year, 7679 in 2009, and from 2500 to 14,000 in 2013-2014.In 2016 the population was estimated to be 6000.
Much of the park is dominated by alpine woodlands, characterised by the snow gum. Montane and wet sclerophyll forest also occur across the ranges, supporting large stands of alpine ash and mountain gum. In the southern wilderness area, dry sclerophyll and wattle forests predominate. Amongst the many different native trees in the park, the large Chinese elm has become naturalised.
Much of the tree cover in the lower sections of the park was seriously burned in bushfires in 2003. Fires are a natural feature of the park ecosystem, but it will take some time for the region to return to its pre 2003 condition.
The mountains are typically covered by metre-deep snow for up to four months of the year. The ski resorts of Thredbo, Selwyn snowfields, Perisher and Charlotte Pass lie within the park. The electric rack railway, called the Skitube Alpine Railway, connects the Alpine Way to the Perisher Valley.
The 655 kilometre Australian Alps Walking Track crosses almost the length of the park. Many thousands of people make the walk to Mount Kosciuszko during the summer. It is 9 kilometres from Charlotte Pass, or 6 kilometres from the Thredbo chairlift. Camping is permitted anywhere in the park except within sight of a road or near a watercourse. The lighting of fires is severely restricted in higher altitudes.
Mountain biking is allowed on all management trails outside of wilderness areas, and on a small number within them: Grey Mare Trail, Round Mountain Trail, Valentine Trail, Hellhole Creek Trail, Cascade Trail, Ingegoodbee Trail and Nine Mile Trail.
Canoeing and swimming in the rivers and lakes are popular in the warmer weather. The rivers and dams are stocked with trout from nearby hatcheries. Seasonal trout fishing is allowed after a permit is obtained. Other attractions include the whitewater rafting, trail riding, Yarrangobilly Caves, Cooleman Caves, Tin Mine Falls, Australia's highest waterfall and Valentine Falls. Guided tours are conducted through several caves in the karst region of Yarrangobilly. Other tours are also available.
Sawpit Creek has a major campground with facilities for caravans and cabins available for rent.
The Snowy Mountains Hydroelectric Scheme
The Snowy River originates in the park and flows south to Victoria. Many tunnels, dams, generators and other parts of the Snowy Mountains Scheme hydro-electric system are located within the park, including the Tantangara Reservoir.
The Snowy Scheme, constructed between 1949 and 1974, is a hydroelectricity and irrigation complex consisting of sixteen major dams; seven power stations; a pumping station; and 225 kilometres of tunnels, pipelines and aqueducts. The Chief engineer was Sir William Hudson. It is the largest engineering project undertaken in Australia.
