Transcript of Australian endangered species

Australian endangered species
Location/Origin
Tasmanian Tiger

Tasmanian Tiger

The precise reasoning for the endangerment of the Tasmanian Tiger is not known, though it appears that it declined due to competition with the dingo, and hunting pressure from humans. The Tasmanian Tigers decline in Tasmania has hastened also because of the introduction of dogs, but mainly due to direct humans declaring them as an alleged pest.

The Tasmanian Tiger, also known as the ‘Tasmanian Wolf’, is native to continental Australia, Tasmania, populating the north and east coast and midland plains regions, but fossils have been uncovered in Victoria, Queensland, South Australia and Western Australia.
Description/
Appearance
Reason for endangerment
Habitat
The Europeans arrived in Tasmania in 1803, at this time, Tasmanian Tigers were wide spread. The Tasmanian Tiger occupied most types of habitat, except dense rainforest. Their preferred habitat was a mosaic of dry Eucalypt forest, wetlands, and grasslands and these are thought to be the Tasmanian Tiger’s prime habitat.
The Tasmanian Tiger was a sandy yellowish-brown-grey colour and had approximately 15-20 distinct dark stripes across its body. Its head was dog/wolf like, had a stiff tail, short legs and dense hair that was short and soft. They had short erect ears, large jaws, and 46 teeth and were very powerful. The female included a back opening pouch, as did the male.
In this presentation we have researched ‘Australian Endangered Species’. The information provided is that of credible websites, detailing our chosen subtopics, the Tasmanian Tiger, Hairy Nosed Wombat and the Short Necked Turtle.
Metzger (2007) discovered the key to evaluating online sources is to determine the credibility and reliability of online information. To identify the accuracy, authority, objectivity, currency and coverage of the information. Including, the degree to which a website is free from errors, assessing who authored the site and what the authors credentials and qualifications are, identifying the purpose of the site and if the information is fact or opinion, whether the information is up to date, and the comprehensiveness or depth of the information provided on the site.



The Australian short necked turtle is found in all but the coldest parts of the Murray-Darling River system. They can also be found in coastal New South Wales rivers, from the Queensland border to the Sydney region, including the Cooper Creek system, along with Fraser Island. They are often seen basking in the warm sun on logs. NSW Government Office of Environment (2014)
The Australian Short Necked Turtle is restricted to the Murray-Darling River system in South Eastern Australia. Australian Reptile Park (2010) They can also inhabit larger rivers and permanent lakes in this region. They nest close to where they live and usually set up these nest 50m. from the waters edge. Michael B. Thompson and Ricky- John Spencer (DOI unknown)
The neck of the Short Necked Turtle is short relative to the other species of turtle, hence their name. Its eyes are bright yellow and it has a single cream or yellowish streak along the side of its head or neck. NSW Government Office of Environment (2014) They are typically an olive green color with brown and cream underneath the body. Younger turtles sometimes have pale yellow spots behind the eyes. Males grow to about 2.2kg. and females can get over 4kg. Micheal B. Thompson and Ricky-John Spencer (DOI unknown)
Some of the reasons for the endangerment of the Australian Short Necked Turtle are foxes and pigs finding nests and robbing the eggs. Other reasons are human impacts, such as plastic bags that turtles think are jelly fish, entanglement and drowning in fishing nets, ropes, floats or traps, habitat destruction, poor water quality and sea grass depletion and disease.

Fossils show that the Northern Hairy Nosed Wombat was once wide spread throughout Eastern Australia, living in Victoria, New South Wales and Queensland. Only three locations were recorded after European settlement, one in New South Wales and two in Queensland. Today there is only one original location at Epping Forest, Queensland and one relocated population in Richard Underwood Nature Refuge, Queensland,
Queensland Government Department of Environment & Heritage Protection (2013).
The Northern Hairy Nosed Wombat lives in semi-arid zones, in locations with deep sandy soils, in which to dig their burrows. In shallow, dry creek beds and gullies which are vegetated with native grasses in Eucalypt woodlands, Q.D.E.H.P.(2013) and Australian Government Department of Environment (2015).
The Yaminon (Indigenous name for Hairy Nosed Wombat),Wildlife Preservation Society of Queensland (2013), are the largest of the three Wombat species, females can weigh over 40kg., with the average adult weighing 32kg. They can reach more than 1m. in length, they have short powerful legs and claws, Q.D.H.E.(2013). Their other distinguishing features are their softer grey fur, longer and more pointed ears, broader muzzle and hairy nose, Johnson (2013).
Since European settlement, there have been a number of factors that have decreased the number of Northern Hairy Nosed Wombats. A major factor being clearing and farming, which has not only decreased their habitat, but created competition for pasture with cattle and sheep. This factor has also increased the impact of drought, fire and disease as their food source and population have been dramatically decreased, Q.G.D.E.H.P.(2013) and Johnson(2013). Another major factor has been dingo predation, Wildlife Preservation Society of Queensland (2013).

Our presentation has outlined the location/origin,
habitat and reason for endangerment of three very different Australian animals, all fascinating, unique
and magnificent. Using many credible and variable internet sites, our research has enabled us to discuss
the Tasmanian Tiger, Northern Hairy Nosed Wombat and the Short Necked Turtle and encapsulate the
devastating impact that human inhabitants, especially
since European settlement in Australia, have had on these amazing creatures. We hope that through imparting such information, knowledge can be gained, care can be fostered, interest can be increased and more work can be done to lessen the impact of human beings on our fellow animal inhabitants.
