Are bears nocturnal12/12/2023 Loss of habitat not only results in reduced availability to food and shelter but also increased stress. The most significant threat to koala populations is habitat loss due to clearing of forests in Australia for urban, industrial and rural development. The Koala is classified as vulnerable on the IUCN Red List of Threatened Species. What are the main threats to koala populations? She happily carries her offspring around constantly until it is old enough to be independent. The koala mother and her young enjoy a very close relationship. For the next two or three months it clings to its mother’s fur during the day, returning to the safety of her pouch at night. It then spends its first six months inside its mother’s pouch. A newborn koala is only the size of a broad bean, blind and hairless. Koalas are marsupials, meaning that they give birth to immature young that develop further in their mother’s pouch. Although clumsy on the ground, the koala is an excellent swimmer, and may cross rivers in order to escape from heavy flooding in one area. They also have two opposable thumbs on their forepaws, enabling them to get a good grip when climbing trees. Koalas have strong arms and legs as well as large feet with sharp claws that help them move about amongst the trees. Conservationists have to move groups of koalas to areas where food is plentiful. Koalas can easily exhaust its’ own supply. Out of over a hundred species of eucalyptus trees that grow in Australia, the koala feeds only on twelve, and will only eat leaves at a particular stage of growth. To digest these leaves, the koala has a special digestive system-a long gut- which measures a colossal two metres and is packed with super micro-organisms that detoxify the vegetation. Koalas even store snacks of leaves in pouches in their cheeks. However, koalas can become dehydrated in very high temperatures.Įach animal eats a tremendous amount for its size-about one kilogram of leaves a day. In Aborigine language, the word ‘koala’ means ‘no water’. They do not drink much water and they get most of their moisture from these leaves. Koalas feed on eucalyptus leaves, especially at night. This is thought to discourage fleas and other animals from living in its fur. Koalas tend to smell strongly of eucalyptus and musk. This sedentary lifestyle can be attributed to the fact they have unusually small brains and survive on a diet of nutrient-poor leaves. During the day they doze, tucked into forks or nooks in the trees, sleeping for up to 18 hours. Koalas are nocturnal marsupials famous for spending most of their lives asleep in trees.
