The koala is known to be a solitary creature. Within its
own species, the only time when there is more than one koala in a
certain area is when the mother is taking care of her joey or during
the mating season. The joey stays with the mother for about a
year, and after that is expected to retreat to its own home range.
During the mating season, male koalas approach female koalas in
their home range. Once the mating has occurred, however, the
males leave and the females are left alone in their tree.
have few natural predators. Many koalas are killed each year in
dog attacks, though. Humans are responsible for a great deal
of koala deaths, as well. It is very common for koalas to be
run over by cars. Also, massive deforestation by humans has
lead to koala deaths.

Koalas are dependent on bacteria to digest the fiber from the
eucalypts leaves they consume (For more on this see the
Nutrition section). This is an
important interaction because it allows the koalas to eat the
eucalypts leaves that other animals cannot. This allows for a
decrease in competition for food between koalas and other organisms.
In times of stress, koalas can contract and suffer from
chlamydial infections (Learn more about this in
Other Facts). These
infections spread very quickly and have serious consequences on the
population. This infection has been known to cause problems in
koalas for quite some time, and in 1995 scientists were able to
isolate the strains that were causing the problem.
