Why koalas are important

IFAW and USC are currently conducting vital research into the impact of fires on koalas to assess their health and resilience and to help at-risk populations survive into the future.

To ensure the safe release of rescued koalas after their rehabilitation, IFAW has also established two dedicated soft release sites where koalas can learn how to climb and rebuild muscle strength. Wondering how you can protect the remaining koalas? Your donation will help IFAW rescue and protect animals around the world. Australia has one of the highest mammal extinction rates in the world.

They are fairly solitary creatures, although they do like to be living in overlapping home ranges in bushland with other Koalas. In the wild in undamaged habitat, the average life span of a Koala is about 10 years. However, where habitat is damaged, such as in suburban areas, they may only live for a few months or years because of the dangers from cars and dogs.

Males tend to have a shorter life span than females because of the stresses of fights during the breeding season and the fact that they tend to move around more than females in search of mates, thus putting them in increased danger from dogs and cars.

Because of the stresses associated with living in the wild, Koalas in the wild can have a considerably shorter life span than Koalas in zoos. The oldest zoo Koala that we know about was a female who lived to 23 years old at Lone Pine Sanctuary in Queensland. He lived to Usually between 18 to 22 hours. They sleep a lot to conserve energy as their diet requires a lot of energy to digest. However, the pouch opening is towards the bottom of the pouch, so when the joey is larger and puts its head out of the pouch it can appear that the pouch faces backwards.

This is thought to be an adaptation to keep them warm in the colder southern winters. They visit these same trees regularly. Each Koala has its own home range, which overlaps those of other Koalas. The size of each home range depends upon a range of factors including the quality of the habitat and the sex, age and social position in the population of the Koala. He rubs this on his trees to indicate to other Koalas that this is his territory.

Koalas also communicate with each other by making a range of noises. Click here for a video! However, not all females in a wild population will breed each year. Some, especially older females, will produce offspring only every two or three years. On its amazing journey to the pouch, it relies on its well-developed senses of smell and touch, its strong forelimbs and claws, and an inborn sense of direction.

Once in the pouch, it attaches itself to one of the two teats which swells in its mouth, preventing it from being dislodged from its source of food. This allows the mother to pass on to the joey special micro-organisms from her intestine which are necessary for it to be able to digest the gumleaves.

Eucalyptus trees have limited calories and nutritional content, so the koalas sleep for up to 20 hours a day to conserve energy and fat. Koalas are asocial animals, but mothers can be seen moving around with their dependent offspring. They have limited predators and parasites, but their greatest threats are pathogens, including the koala retrovirus and Chlamydiaceae , droughts, and wildfires. The marsupials have been part of Australian history for thousands of years; indigenous Australians hunted them for fur as depicted in cave art and myths.

The koala is used as a symbol of Australia alongside the kangaroo because of its distinctive appearance and a limited geographic range. They were hunted in the 20th century for fur, while large-scale cullings in Queensland prompted a public outcry to protect and conserve the species which has been listed as vulnerable as habitat destruction and urbanization continue to diminish its natural habitat. The largest ecological role of the koalas is felt in the eucalypt forests, where they spend most of their time.

The koala population in Australia is estimated at 80,, but before the arrival of the aboriginal people, their population ranged into millions. Such a large population would have a significant impact on the canopy density and the amount of light reaching the forest floor.

Koalas consume the excess vegetation, therefore, reduce the biomass that fuels frequent and intense fires. During the rainy season, koala droppings act as nutrients for the regeneration of undergrowth, ensuring that the forests regenerate to sustain future life. These excrements also serve as food for insects and small rodents.
