Yellow-footed Rock-wallaby
The yellow-footed rock-wallaby (''Petrogale xanthopus''), formerly known as the ring-tailed rock-wallaby, is a member of the macropod family (the marsupial family that includes the kangaroos, wallabies, tree-kangaroos, and wallaroos). Taxonomy This species was first described by John Edward Grey in 1855 in the '' Proceedings of the Zoological Society of London''. The description was based on two specimens (a male and a female), which were possibly collected from the Richmond River. The illustration that accompanied the published description was produced by Joseph Wolf. Description The yellow-footed rock-wallaby is grey to fawn-grey above and light-coloured below with a black mid-dorsal stripe from the crown of the head to the centre of the back. There is a distinct white cheek stripe, with ears ranging in colour from orange to grey-brown. The forearms and hind legs are bright yellow to rich orange to a light orange-brown. The tail is orange-brown irregularly ringed with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Goats In Australia
Feral goats are an invasive animal species in Australia. First arriving in the 18th century with European settlers, feral goat populations originated from escaped domestic individuals. Today, feral goats are found across Australia, where they cause economic and environmental damage through overgrazing and competition with livestock and native marsupials. History Feral goats came to Australia with the first fleet in 1788. For instance, cashmere goats were brought into South Australia in 1837. In the 1860s, angora goats and cashmere goats were imported from Asia in an order to start a goat fibre industry. Some herds were set free when the industry collapsed in the 1920s. Goats were also taken around Australia with settlers, railway construction groups and miners. The recent populations of the feral goat have established from goats used to control weeds in plantation forests and woody weeds in inland New South Wales and Queensland. The current feral goat populations in Australia repr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Protected Area
An Indigenous Protected Area (IPA) is a class of protected area used in Australia; each is formed by voluntary agreement with Indigenous Australians, and declared by Aboriginal Australians and Torres Strait Islander representative organisations. Each is formally recognised by the Australian Government as being part of its National Reserve System. The areas may comprise land and sea, and are managed by Indigenous groups for the conservation of biodiversity. Managing IPAs also helps to protect the cultural values of their country for future generations, and has benefits for Indigenous health, education, economic and social cohesion. Text may have been copied from this source, which is available under aAttribution 3.0 Australia (CC BY 3.0 AU)licence. As of 2020, there were 78 IPAs, covering around 46.53% of the National Reserve system. In September 2021, a further seven IPAs were declared, which will lead to IPAs comprising more than half of Australia's National Reserve System ...

Brush-tailed Rock-wallaby
The brush-tailed rock-wallaby or small-eared rock-wallaby (''Petrogale penicillata'') is a kind of wallaby, one of several rock-wallabies in the genus '' Petrogale''. It inhabits rock piles and cliff lines along the Great Dividing Range from about 100 km north-west of Brisbane to northern Victoria, in vegetation ranging from rainforest to dry sclerophyll forests. Populations have declined seriously in the south and west of its range, but it remains locally common in northern New South Wales and southern Queensland. However, due to a large bushfire event in South-East Australia around 70% of all the wallaby's habitat has been lost as of January 2020. In 2018, the southern brush-tailed rock wallaby was declared as the official mammal emblem of the Australian Capital Territory (ACT), although it has not been seen in the wild in the ACT since 1959. Taxonomy ''Petrogale penicillata'' was first described by John Edward Gray in 1827. The taxon has been named for a species com ...

Foundation For National Parks & Wildlife
The Foundation for National Parks & Wildlife is an Australian not-for-profit, non-governmental organisation that was incorporated on 29 June 1970. Its purpose is to foster the protection of Australia's native plants, animals and cultural heritage through fundraising for environmental education and conservation projects. Since 1970 the organisation has raised more A$ 45 million ($1 million+ per year on average) for environmental conservation. The foundation was founded as a New South Wales–focused organisation, however in 2000 the foundation's members voted to amend its constitution so that the organisation could expand the scope of its work Australia-wide. Projects Since 1970 the foundation has acquired over 600,000 hectares of habitat and places of natural beauty for 50 national parks and nature reserves, including Mungo National Park, the Daintree Rainforest, and South Australian protected areas. The foundation acquires land through purchase, donation and bequest. The founda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joey (marsupial)
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Cats In Australia
Cats (''Felis catus''), initially introduced into Australia with the First Fleet in 1788, now number more than 11 million distributed across more than 90% of the continent including every major island. They are the second most popular pet by household (third most populous overall after dogs and fish). In 2023 there were 5.3 million kept as pets of which approximately 95% are neutered. In addition there are estimated to be up to 6 million feral cats found in almost every remote area across the country.

Arkaroola
Arkaroola is the common name for the ''Arkaroola Wilderness Sanctuary'', a wildlife sanctuary situated on of freehold and pastoral lease land in South Australia. It is located north of the Adelaide city centre in the Northern Flinders Ranges, adjacent to the Vulkathunha-Gammon Ranges National Park and the Mawson Plateau. The most common way to get there is by car, but air travel can be chartered from Parafield Airport, Adelaide Airport or Aldinga Airfield. It was used as a location set for the 2002 film '' The Tracker''. History The area's first people are the Adnyamathanha. One of their dreamtime or creation stories says that Arkaroo, a mythical monster, drank Lake Frome dry. He then crawled up into the mountains. When he urinated he created the waterholes that are a feature of the area. His movement over the land created Arkaroola Creek. The first Anglo-Europeans to visit the area was explorer Edward Eyre in 1840 and the surveyor George Goyder in 1857. There was a ...

Mutawintji National Park
The Mutawintji National Park, formerly the Mootwingee National Park, is a protected national park that is located in the Far West region of New South Wales, in eastern Australia. The national park is situated approximately west of Sydney and about north-east of . Features and location The rugged, mulga-clad Byngnano Range is dissected by colourful gorges, rockpools and creek beds lined with red gums. Scattered among the caves and overhangs are Aboriginal rock art and engravings. In 1979, the Foundation for National Parks & Wildlife purchased and fenced , in the Coturaundee Ranges, now part of Mutawintji National Park, for the conservation and protection of the yellow-footed rock wallaby. Follow-up funding of fox eradication in the reserve ensured the survival of this last population of yellow-footed rock-wallabies in New South Wales. Of the wild animals, wedge-tailed eagle, peregrine falcon, short-billed correllas, zebra finches, budgerigars, apostle birds and magpie ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...
