As an Australian native marsupial, the koala has been listed as endangered across majority of its natural habitats. At one point, its population had grown to almost 10 million, but has dropped to 100,000 or less still in the wild because of human activity. Many have taken action to restore the population of the koala. The koala’s background proves that their population decline is effected mainly on humans. Numerous people refer to the koala as a koala bear, but in reality it is a marsupial, similar to a wombat. It is found in the Australian states of Queensland, New South Wales, Victoria, and South Australia. This nocturnal animal lives mostly in eucalyptus forests where its main food source is the leaves of the tree. Without disturbance, the koala can live up to 15 years. While it may have no natural predators in the wild, it does have exposed skin on its face, hands, and feet which can make it vulnerable to fires and further threaten the population. Although other factors like fires harm koalas, humans have the most impact on the koala. The koala may not be …show more content…
Locals in Queensland, New South Wales, Victoria, and South Australia with acreage or grazing property can protect the eucalyptus trees from being cut down. People can also plant more trees to create more homes and to make food more abundant for koalas. When driving, people can be more cautious around eucalyptus trees and watch for crossing koalas. For those who do not live in Australia can still help by donating to koala conservation organizations. Koalas can make a comeback, but not without the help of people. Humans have caused this problem and humans can fix this problem. The shrinking population can grow if eucalyptus tree harvesting is controlled, dogs are disciplined, and if people are mindful when driving. Without fast actions to fix this problem it will continue to get
Thirteen bird species and ninety-six species of reptiles and frogs are found across the Flinders semi-arid biome. The mammal species that live there are yellow-footed rock-wallabies, emus, flinders ranges worm-lizard and kangaroos. There are animals in my biome that are used by humans. For example, Kangaroos and Emus are farmed for their meat. Restaurants serve kangaroo and emu steaks on their menus. Supermarkets have kangaroo meat for sale. Kangaroo meet is also used as pet food for cats and
Species possibly saved as a result of population management include the Koala, Partula snails, and Sarracenia alabamensis. The koala was experiencing a population decline in Australia which prompted an initiative known as the Koala Habitat Program. The goal of this program is to increase the size of the habitat for the koala. The Queensland Government has provided $22.5 million in funding to acquire new land (Queensland Government, 2014). The Partula snail is another species very critically endangered. As this species’ population recovers in captivity, the hope is to release them into the wild. This process has to be done carefully after the African land snail was imported to a small island in the Pacific and soon got out of control. This snail was eating the crops that grow on the island. Eventually, a second species of snail, the Florida rosy wolfsnail, was brought in to prey on the Partula snail to get the population under control (Marwell Wildlife, 2014). The Sarracenia Alabamensis, also known as the Cane-brake pitcher plant, was in need of a program to stabilize its population. This plant was endangered because it was located in areas where land was cheap to acquire and when the land was developed, it reduced the number of plants. The first program
The leaves of the eucalyptus tree contain toxic chemical compounds. As a result only few animals are able to consume the leaves, therefore giving the tree a better chance of survival.
Among the many different marsupials in the world, there is one that stands out and is recognized, not only for its looks, but also for the hardships that it deals with in being a koala. The koala originated in Australia, and was discovered by trappers around the time of 1798. Many rare and exotic animals have been found in Australia, because of its remoteness and isolation from most of the civilized world. Australia has been described as a huge ark, a giant lifeboat, cut off from contact with the rest of the world and carrying with it a group of unique creatures (Serventy 1975). The creatures that inhabit Australia are made up of many different classifications of animal groups that have found themselves all living
Australia have many animals that comes in all shapes, sizes, and colors. They all have different ways of adapting to the environment. In Australia, they have more than 378 mammal species. Some stay in trees and some stay on land.
Western Grey Kangaroo enclosures should contain trees, shrubs, and other forms of shade to stimulate their natural habitat with grassy areas for grazing. Shrubs and trees should be planted away from the fence to prevent the risk of collision injuries. Shade cloth or similar attached to the fence also provides shelter and prevents stress to the animals from outside influences. Otherwise the enclosure should be relatively free of obstacles to minimise the likelihood of the animals injuring themselves.
In a summary, Kolbert explains the extinctions of a variety of different major animal species that became extinct. She also explains that if trends in the environment continue that the biggest extinction in history will occur soon. If global warming, deforestation, and glaciers continue to melt she says that more and more species will continue to become extinct. She explains how humans need to be more conservative and careful with what they’re doing to prevent extinction.
“Hmm, I haven’t heard about the eucalyptus trees being cut down. Could you tell me more about this predicament?” replies the Koala in a quiet tone.
Have you ever wondered how in the world a species can survive in a crazy place like the Outbacks of Australia? Many native species have had to make changes to survive, including everything from their appearances to their diet, some due to the negative effects of the introduction of new species.
Previous studies mostly recognized multiple MUs in the northern region but lacked support for multiple MUs in the southern (Sherwin, Timms, Wilcken, & Houlden, 2000). However, all koala populations in this study should be treated as independent management units (MU). MUs are demographically independent populations which have little gene flow among them and the degree of population genetic divergence depends on the biology and population history of the species (Palsbøll, Berube, & Allendorf, 2007). Results in NetView (k-NN=10) showed independent clustering of the populations with little gene flow between them. Moreover, populations in St Lawrence, Ipswich, Lismore, Port Macquarie, Cape Otway and Mt Lofty had moderate to high Fst values ranging from 0.024 to 0.216. Populations on Magnetic Island and St Bees Island should also be treated as independent MUs due to isolation and lack of natural gene flow. Although Western Sydney and South Gippsland populations did not show high Fst value, the former had 5 private alleles and 0.021 rare alleles. Although South Gippsland population MU may not seen supported by Fst value, number of private alleles or proportion of rare alleles, it should be treated with care as this may be misled by the low within-population variation and/or recent
Red Kangaroos are marsupial herbivores who are only native to Australia and Papa New Guinea. They are the world largest

The lumber industry has increased in production of furniture and collection of materials. This has ridden the Koalas of their major eucalyptus food resource and polluted most of their water supply, contributing to malnourishment and death. The trees were also their homes due to them being marsupials of which have a body composition to swing and hang on to limbes from a tree. Air pollution is another major impact as many were found to have died from a health risk that hurt their lungs and triggered bronchitis like inflammations and/or cancerous risks. This has been caused by coal and ash release within the air and the loss of trees also means less of filtration resulting more of it to be inhaled and affecting their lungs and system. These little things are what affects most animal species not just Koalas as they inhale and it affect their health systems and the waters are also polluted so by looking at this one animal we can not only base one problem but many resulting in greater effects that also affect us without us realizing
Bill Freedmen, author of “Endangered Species—Human Causes Of Extinction and Endangerment” notes, “scientists approximate that present extinction rates are 1,000 to 10,000 times higher than the average natural extinction rate.” These distressing numbers should be acted upon to save the endangered species and avoid the catastrophic change to this planet if these species were to become extinct. In order to produce change, people need to recognize that habitat loss, climate change, and poaching are all factors in why our animal species are going extinct.
The problem is that the many animals are decreasing due to humans destructing their habit. For example, Tasmanian devils are endangered is because they are getting tumors that are called devil facial tumor disease. This is causing their population to decrease as there isn’t much they can do when they have a tumor. Tasmanian Devils are also losing their habitat because the farmers need more land to grow crops and they live there it’s not ideal as then they starve and can’t get what they need to live. Forest land has been cleared over time by humans due to deforestation as people are chopping down the trees to have more land to grow crops. Land clearing is the process of removing trees, stumps, brush, stones and other obstacles from an area as required to increase the size of the crop producing land base of an existing farm or to provide land for a new farm operation. European settlement has significantly altered Australia's natural landscape. About 90% of native food in the east has been removed for agriculture, industry, transport and human habitation. About 50% of Australia's rainforests have been cleared and Australia covered by forest or woodland has been reduced by more than one-third. Around 5% of Australia's higher plants, 7% of reptiles, 9% of birds, 9% of freshwater fish, 16% of amphibians and 23% of mammals are listed as Extinct, Endangered or Vulnerable. Over 5 million parrots, honeyeaters, robins and other land birds are killed each year by land clearing. For
