The Top End
Top End
of Australia's Northern Territory
Northern Territory
is a geographical region encompassing the northernmost section of the Northern Territory, which aside from the Cape York Peninsula
Cape York Peninsula
is the northernmost part of the Australian continent. It covers a rather vaguely defined area of perhaps 400,000 km2 (154,441 sq mi) behind the northern coast from the Northern Territory

to the south, beyond the huge Kakadu National Park. The Top End

contains both of the Territory's cities and one of its major towns, Darwin, Palmerston and Katherine. The well-known town of Alice Springs

is located further south, in the arid southern part of the Northern Territory, sometimes referred to by Australians as the Red Centre. The landscape is relatively flat with river floodplains and grasslands with eucalyptus trees along with rocky areas and patches of rainforest, and in western Arnhem Land
Arnhem Land
a high rugged sandstone plateau cut through with gorges, much of which is in Kakadu National Park. The rivers that form the wetlands include the South and East Alligator Rivers, Mary River, and the Glyde River. The climate is tropical monsoon with a wet and dry season, bringing the highest rainfall in northern Australia

(over 1,200 mm (47 in) per year). Temperatures do not fluctuate widely throughout the year. There are a number of islands off the Top End

Flora[edit] Most savanna in Australia
Australia
is used for grazing livestock, but in this far north, vast areas of grassland are in their original state and dotted with Darwin stringybark and Darwin woollybutt eucalyptus trees; these grasslands are a unique and highly important ecoregion. The sandstone plateau area of the ecoregion is a particularly rich centre of biodiversity supporting a unique heathland flora. Much of the Top End is within the Arnhem Land
Arnhem Land
tropical savanna ecoregion, which to the south merges into the semi-arid mulga scrubland, mallee, and sand dunes of the centre (see Carpentaria, Kimberley, and Ord Victoria Plain). The transition is gradual, and the demarcation line that divides the Top End
Top End
from the centre is arbitrary.[1] Fauna[edit] This area is home to unique wildlife. The rivers and estuaries are home to large populations of both saltwater and freshwater crocodiles, as well as bull sharks, sawfish, and dugongs. The wetlands are a rich habitat vital to bird migration and home to large populations of birds, including the world's largest breeding colony of magpie geese, as well as large numbers of rodents and snakes. Endemic species of the Top End
Top End
include the Woodward's wallaroo, Oenpelli python, chestnut-quilled rock-pigeon, Arnhem Land
Arnhem Land
rock rat, and several species of skinks. Other reptiles include frill-necked lizards and large monitor lizards (known locally as goannas). Snakes include the olive python, death adder (Acanthophis), mulga, water python (Liasis fuscus), and various others. The plateau is home to many of these endemics, especially invertebrates, fish, and frogs, including, for example, hundreds of species of ants. The offshore islands are home to unique subspecies of some of this wildlife. Threats and preservation[edit] The landscape is well preserved and most of the area is traditionally managed by Aboriginal land trusts, including Kakadu, which is Australia's largest national park and a World Heritage Site. Although some populations have declined, there have been no major extinctions of wildlife in this area. Darwin, though, is a growing city and a base for agriculture and mining, both of which threaten habitats. Introduced plants and animals, such as the water buffalo, are also changing natural habitats, and there has been criticism of the way the local population has changed the fire regimes used to control the bush foliage, in which large areas are burnt each year and allowed to renew. Also there was a large aboriginal trade in that area which has mostly settled down. References[edit]
