Arnhem Land Tropical Savanna
The Arnhem Land tropical savanna is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in Australia's Northern Territory. Geography The ecoregion occupies the peninsula of Arnhem Land and its offshore islands, including the Tiwi Islands, Groote Eylandt, and the Wessel Islands. Western Arnhem land has rugged sandstone plateaus and gorges. The rest of the peninsula has gentler topography, and includes broad river floodplains and coastal lowlands. Arnhem Land is bounded on the northwest by the Timor Sea, on the north by the Arafura Sea, and on the east by the Gulf of Carpentaria. The Kimberley tropical savanna ecoregion lies to the southwest, and the Carpentaria tropical savanna to the southeast. IBRA regions The ecoregion includes six IBRA regions – Arnhem Coast, Arnhem Plateau, Central Arnhem, Darwin Coastal, Pine Creek, and Tiwi Cobourg. Climate The ecoregion has a tropical savanna climate. Rainfall is strongly seasonal, with a summer wet s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kakadu National Park
Kakadu National Park is a protected area in the Northern Territory of Australia, southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census. Kakadu National Park is located within the Alligator Rivers Region of the Northern Territory, covering an area of , extending nearly from north to south and over from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second-largest national park in Australia, after the Munga-Thirri–Simpson Desert National Park. Most of the region is owned by the Aboriginal traditional owners, who have occupied the land for around 60,000 years and, today, manage the park jointly with Parks Australia. It is highly ecologically and biologically diverse, hosting a wide range of habitats and flora and fauna. It also includes a rich heritage of Aboriginal rock art, incl ...

Arnhem Plateau
The Arnhem Plateau is an Interim Biogeographic Regionalisation for Australia, Australian bioregion located in the Northern Territory of Australia, comprising an area of of the raised and heavily dissected sandstone plateau that characterises central Arnhem Land in the Top End of the Northern Territory. Description The boundary of the Important Bird Area (IBA) is largely defined by the extent of vegetation suitable for white-throated grasswrens. The most important habitat for grasswrens is bare rock and Triodia (grass), spinifex grassland. Other vegetation includes open monsoonal savanna woodland and patches of rainforest, especially that dominated by the endemic tree ''Allosyncarpia ternata''. About a quarter of the IBA is within Kakadu National Park; a southern outlier is in Nitmiluk National Park, with much of the remainder due to be incorporated in the Wardekken Indigenous Protected Area. Birds Identified as an important bird area by BirdLife International, the plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antilopine Kangaroo
The antilopine kangaroo (''Osphranter antilopinus''), also known as the antilopine wallaroo or the antilopine wallaby, is a species of Macropodidae, macropod found in northern Australia: in Cape York Peninsula in Queensland, the Top End of the Northern Territory, and the Kimberley (Western Australia), Kimberley region of Western Australia. It is a locally common, gregarious grazer. Taxonomy The description of the species by John Gould was published in 1842, one of four new species of 'kangaroos' presented before the Zoological Society of London in 1841. The type location was given as Port Essington. The author assigned the new species to the genus ''Osphranter'', a taxon later submerged as a subgenus of ''Macropus'', and recognised an affinity with his earlier description of ''Macropus robustus'' (known as the common wallaroo or euro). A taxonomic restructuring in 2019, based on genetic analysis, promoted ''Osphranter'' back to genus level, redefining the antilopine kangaroo an ...

Common Wallaroo
The common wallaroo (''Osphranter robustus''), also known as the euro, hill wallaroo, or simply wallaroo, is a species of macropod. The word ''euro'' is particularly applied to one subspecies (''O. r. erubescens'').WE Poole and JC Merchant (1987): ''Reproduction in Captive Wallaroos - the Eastern Wallaroo, Macropus-Robustus-Robustus, the Euro, Macropus-Robustus-Erubescens and the Antilopine Wallaroo, Macropus-Antilopinus.'' Australian Wildlife Research 14(3) 225 - 242online link/ref> The eastern wallaroo is mostly nocturnal and solitary, and is one of the more common macropods. It makes a loud hissing noise and some of the other subspecies are sexually dimorphic, like most wallaroos. Subspecies There are four subspecies: *the eastern wallaroo (''O. r. robustus'') – found in eastern Australia; males of this subspecies have dark grey fur, almost resembling the black wallaroo (''Osphranter bernardus''). Females are lighter, being almost sandy in colour. *the euro or western wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Wallaby

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on Australia's Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allosyncarpia Ternata
''Allosyncarpia ternata'', commonly known as ''an-binik'', is a species of rainforest trees constituting part of the botanical family Myrtaceae and included in the eucalypts group. The only species in its genus, it was described in 1981 by Stanley Blake of the Queensland Herbarium. They grow naturally into large, spreading, shady trees, and are endemic to the Northern Territory of Australia. They grow in sandstone gorges along creeks emerging from the Arnhem Land plateau. The common name ''anbinik'' comes from the Kundedjnjenghmi and Kundjeyhmi dialects of Bininj Kunwok, spoken in West Arnhem Land. In other dialects, such as the Kunwinjku spoken in Gunbalanya, the tree is known as ''manbinik''. Distribution and habitat The tree dominates the closed monsoon rainforest communities along the sandstone escarpment of the western Arnhem Land Plateau. The distribution of the species appears to be limited to areas not subject to wildfire. Ecology ''Allosyncarpia'' dominated rainf ...

Tropical Savanna Climate
Tropical savanna climate or tropical wet and dry climate is a tropical climate sub-type that corresponds to the Köppen climate classification categories ''Aw'' (for a dry "winter") and ''As'' (for a dry "summer"). The driest month has less than of precipitation and also less than 100-\left (\frac \right)mm of precipitation. This latter fact is in a direct contrast to a tropical monsoon climate, whose driest month sees less than of precipitation but has ''more'' than 100-\left (\frac \right) of precipitation. In essence, a tropical savanna climate tends to either see less overall rainfall than a tropical monsoon climate or have more pronounced dry season(s). It is impossible for a tropical savanna climate to have more than as such would result in a negative value in that equation. In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year. Tropical savanna climates often feature tree-studded grasslands due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
