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 ... [...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. Water buffalo, which are now an environmental pest, were released in the area in the late 19th century, and missionaries established a mission at Oenpelli (present-day Gunbalanya) in 1925. A few pastoralists, crocodile hunters and wood cutters made a living at various times during the 20th century. The area was given protected status bit by bit from the 1970s onwards. The park is located within the Alligator Rivers Region of the Northern Territory. It covers 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 Dese ...

Antilopine Kangaroo
The antilopine kangaroo (''Osphranter antilopinus''), also known as the antilopine wallaroo or the antilopine wallaby, is a species of macropod found in northern Australia: in Cape York Peninsula in Queensland, the Top End of the Northern Territory, and the 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 and the red kangaroo, among others, as spe ...

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 wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Wallaby
The agile wallaby (''Notamacropus agilis''), also known as the sandy wallaby, is a species of wallaby found in northern Australia and southern New Guinea. It is the most common wallaby in north Australia. The agile wallaby is a sandy colour, becoming paler below. It is sometimes solitary and at other times sociable and grazes on grasses and other plants. The agile wallaby is not considered threatened. Subspecies The four subspecies of the agile wallaby are: *''N. a. agilis'', the nominate subspecies, is found in the Northern Territory. *''N. a. jardinii'' is found on the northern and eastern coasts of Queensland. *''N. a. nigrescens'' is found in the Kimberley and Arnhem Land regions of Western Australia. *''N. a. papuanus'' is found in southern and southeastern Papua New Guinea and some neighbouring islands. Description Male agile wallabies are considerably larger than females, having a head and body length of up to and weighing while the females grow to in length and weigh ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles 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 for life in swamp ... [...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 ...

Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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). 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 to its dryness, rather than thick jungle. It is this widespread occurrence of tall, coarse grass (called savanna) which has led ...
