Query: Does the koala eat anything other than eucalyptus?
Koalas typically inhabit open eucalypt woodlands, and the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to 20 hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives. These young koalas, known as joeys, are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by various pathogens, such as Chlamydiaceae bacteria and the koala retrovirus, as well as by bushfires and droughts.
Visitors are allowed to hold koalas for a fee. Strict regulations ensure that each koala is not held for more than thirty minutes every day. Fees paid for souvenir photos help fund new enclosures, research projects and eucalyptus plantations.
"Eucalyptus viminalis" is widely distributed in the cooler areas of Australia where the leaves are the favoured food of koalas. Sap has a 5–15% sugar content which makes it an essential part of the energy budget for arboreal or tree dwelling marsupial mammals like yellow-bellied, sugar and other gliders. Koalas reintroduced to Kangaroo Island impact on native "E. viminalis" and is part of a A$4,000,000 management project from 2005-9.
In 1984, the Tama Zoo in western Tokyo welcomed its first koala, and the government of Australia sent six koalas to Japan as a token of goodwill. As a result, according to "The Anime Encyclopedia" by Jonathan Clements and Helen McCarthy, Japan went into a koala frenzy and anything to do with koalas became very popular. It was during this "koala-mania" that the Noozles was made, as was another anime, コアラボーイ コッキィ("Koala Boy Kokki"), which would later be broadcast alongside "Noozles" on Nickelodeon's Nick Jr. block in 1988, as "Adventures of the Little Koala".
The giant koala was an arboreal marsupial weighing about 13 kg, a little more than modern koalas. It is the largest known tree dwelling marsupial ever to have lived. Scientists say there is a clear similarity between the physical appearance of "P. stirtoni" and the modern koala. It is assumed that the giant koala was a folivore which was specialised to feed on eucalyptus leaves, like its extant relative.
More than 40,000 km² of land has been mapped for the Koala Habitat Atlas. Unlike other mapping projects, the Atlas does not merely pinpoint the location of individuals in the species. It displays the occurrence of suitable koala habitat (even if there are no koalas there at present) that can be 'restocked' in future if necessary. More than 1,000 sites were identified in South East Queensland alone.
An essential oil extracted from eucalyptus leaves contains compounds that are powerful natural disinfectants and can be toxic in large quantities. Several marsupial herbivores, notably koalas and some possums, are relatively tolerant of it. The close correlation of these oils with other more potent toxins called formylated phloroglucinol compounds (euglobals, macrocarpals and sideroxylonals) allows koalas and other marsupial species to make food choices based on the smell of the leaves. For koalas, these compounds are the most important factor in leaf choice.
Koala Walkabout opened on March 10, 2012, in the Australian Outback area. It features koalas, red kangaroos, wallabies, kookaburras, a blue-tongued skink, and lorikeets. The koalas, Kobi and Tekin, are two males on loan from the San Diego Zoo. Kobi and Tekin spend most of their time dozing in a eucalyptus tree within their climate-controlled exhibit. The zoo is currently one of only ten in the nation to exhibit koalas. This exhibit has since closed.
Koala Territory was first opened in 2005, and houses three koalas, two males named Gooanroo and Toorie, and a female named Alinga. Yooranah was the offspring of Alinga and Goonaroo, and was born in 2013 and died in 2016. Toorie is the offspring of Alinga and Goonaroo, and still lives at the park today. Koala Territory is decorated with Aboriginal-inspired artwork, and features a garden of eucalyptus plants.
Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist because it has a natural range that includes most of North and Central America, and it is omnivorous, eating berries, insects, butterflies (Hackberry Emperor, for example), eggs and small animals. Monophagous organisms feed exclusively, or nearly so, on a single other species.
It is one of the species whose leaves are used for food by koalas. It flowers most years, something that is unusual amongst the Eucalypts it does not yield nectar or pollen in quantities that are useful for beekeepers.
The koala lives predominantly on a diet of eucalyptus plants. Many of these trees are being cleared each year. The primary focus of the AKF is getting new legislation in place to protect Koala trees. The organisation receives no form of government funding by choice, because this leaves the AKF to speak freely for Koalas without the constraints of government. Therefore, the AKF relies on donations, sponsorship, and fundraising to finance its ongoing work. AKF research indicates that somewhere between 52,000 and 87,000 koalas remain in the wild. Local extinctions are occurring regularly, and AKF believes that the only way to protect and regenerate populations into the future is with a Koala Protection Act.
The modern koala is the only extant member of Phascolarctidae, a family that once included several genera and species. During the Oligocene and Miocene, koalas lived in rainforests and had less specialised diets.[15] Some species, such as the Riversleigh rainforest koala (Nimiokoala greystanesi) and some species of Perikoala, were around the same size as the modern koala, while others, such as species of Litokoala, were one-half to two-thirds its size.[16] Like the modern species, prehistoric koalas had well developed ear structures which suggests that long-distance vocalising and sedentism developed early.[15] During the Miocene, the Australian continent began drying out, leading to the decline of rainforests and the spread of open Eucalyptus woodlands. The genus Phascolarctos split from Litokoala in the late Miocene[15][17] and had several adaptations that allowed it to live on a specialised eucalyptus diet: a shifting of the palate towards the front of the skull; larger molars and premolars; smaller pterygoid fossa;[15] and a larger gap between the molar and the incisor teeth.[18]
The grey gum regenerates by regrowing from the base and branches after bushfire. Trees live for over a hundred years. The grey-headed flying fox ("Pteropus poliocephalus") eats the flowers, while the leaves form a staple of the diet of the koala ("Phascolarctos cinereus"). Leaves in winter contain less nitrogen than those in summer, which the koalas make up for by eating more in winter months. The brown-headed honeyeater ("Melithreptus brevirostris") and yellow-tufted honeyeater ("Lichenostomus melanops") have been observed eating gum exudate from the stems. 
Fieldwork at several sites around central New South Wales showed that the red wattlebird ("Anthochaera carunculata") and noisy friarbird ("Philemon corniculatus") preferred to forage on the foliage of the grey gum over other trees, with the former appearing to oust the latter if both species were present.
"Eucalyptus botryoides" regenerates after bushfire by resprouting from epicormic buds and its woody lignotuber. Plants have been dated at 600 years of age. It also drops branches, and these have been known to grow roots. The wet environment and water-absorbing qualities of the thick, fibrous bark facilitate this.
The koala ("Phascalarctos cinereus") eats the leaves, and ants consume the nectar. The species is highly susceptible to psyllids.
A long-lived tree, "Eucalyptus robusta" can live for at least two hundred years. Trees regenerate by regrowing from epicormic buds on the trunk after bushfire. The grey-headed flying fox ("Pteropus poliocephalus") eats the flowers, and the koala ("Phascalarctos cinereus") eats the leaves. "Eucalyptus robusta" appears to be one of several key species of eucalypt for the koala in the Shire of Noosa in Queensland. The musk lorikeet feeds on the nectar of the blossoms. It is a keystone species on the New South Wales Central Coast and Illawarra regions, where it is one of few reliable winter-flowering plants. Stands of "E. robusta" have been drastically reduced by land clearance. Some remnant trees in Robson Park in the Sydney suburb of Haberfield are the last vestiges of the Sydney Coastal Estuary Swamp Forest Complex community in Sydney's inner western suburbs.
Species that require specialized niches and or cannot disperse and effectively colonize suitable habitat will be affected if this current trend of human induced climate change continues. It is estimated that 52% of the already declining population of frogs and 35% of birds will be affected. Koalas are listed by the IUCN as one of the top 10 species to become extinct. Koala populations are already at risk because of habitat modification and chlamydia. Increasing CO2 levels will affect the nutrient availability of eucalyptus leaves further weakening koala populations, increased frequency of droughts and bushfire will force koalas to seek new habitats, exposing them to the dangers of predation and injury from traffic.
"Stankervision" also features some cartoons, but in "Stankervision" style. One regular such cartoon is about the adventures of "Inebriated the Koala", which was created by Waco O'Guin in 1993 and is introduced as "everyone's favorite eucalyptus-eating marsupial", to which the koala replies "Eucalyptus? You can lick THIS!" as he points to his crotch.
With sandy ridges of low sclerophyll forest, there are also other vegetation types present of rainforest remnants, sheoak or "Casuarina" sp. forest stands, "Melaleuca" swamps, salt meadows, and mangrove stands. The site hosts one of the important food trees of the koala, Queensland's faunal emblem, is the blue gum ("Eucalyptus tereticornis"). Other species around include the scribbly gum ("Eucalyptus signata").
Herbivorous marsupials are classified in the order Diprotodontia, and further into the suborders Vombatiformes and Phalangerida. The Vombatiformes include the koala and the three species of wombat. One of Australia's best-known marsupials, the koala is an arboreal species that feeds on the leaves of various species of eucalyptus. Wombats, on the other hand, live on the ground and feed on grasses, sedges and roots. Wombats use their rodent-like front teeth and powerful claws to dig extensive burrow systems; they are mainly crepuscular and nocturnal.
It can grow to 50 metres in height, though is mostly seen between 20 and 30 metres tall. Growing north from Wyong in New South Wales up to south east Queensland, in high rainfall areas, prone to fire. Leaves eaten by koalas. Yellow-bellied gliders eat the sap of the Grey Gum.
Unlike kangaroos and eucalyptus-eating possums, koalas are hindgut fermenters, and their digestive retention can last for up to 100 hours in the wild, or up to 200 hours in captivity.[45] This is made possible by the extraordinary length of their caecum—200cm (80in) long and 10cm (4in) in diameter—the largest proportionally of any animal.[49] Koalas can select which food particles to retain for longer fermentation and which to pass through. Large particles typically pass through more quickly, as they would take more time to digest.[45] While the hindgut is proportionally larger in the koala than in other herbivores, only 10% of the animal's energy is obtained from fermentation. Since the koala gains a low amount of energy from its diet, its metabolic rate is half that of a typical mammal,[44] although this can vary between seasons and sexes.[45] The koala conserves water by passing relatively dry faecal pellets high in undigested fibre, and by storing water in the caecum.[47]
Although degraded by the removal of native vegetation along its length for flood control, the creek does contain areas of freshwater and tidal wetlands, with some dry eucalyptus forest in the catchment. Wildlife includes native species such as bandicoots, koala, and lace monitor.

"Eucalyptus saligna" regenerates by regrowing from epicormic buds on the trunk and lower branches after bushfire. Trees live for over two hundred years. The grey-headed flying fox ("Pteropus poliocephalus") eats the flowers, the koala ("Phascalarctos cinereus") eats the leaves, and crimson rosella ("Platycercus elegans") eats the seed. The longhorn beetle species "Paroplites australis", "Agrianome spinicollis" and "Tessaromma undatum" have been recorded from the Sydney blue gum.
