FOOD


Koalas are considered as herbivores
They consume eucalyptus leaves and bark from 12
different eucalyptus tree species. They also consume
mistletoe and box leaves. They can eat up to 2 lb of
leaves a day. Koalas mostly get there water from
plants.
HUMAN IMPACT

THREATS: Once numbering in the millions,
koalas suffered major declines in population
during the 1920s when they were hunted for
their fur. Today, habitat destruction, traffic
deaths, and attacks by dogs kill an estimated
4,000 koalas yearly

There are less than 100,000 koalas around the
world today.
OFFSPRING

Koalas breed once a year. Gestation lasts 35
days, after which one koala is born. The baby
koala is very small when it is born, and lives
in its mother's pouch for five to seven months.
After this time, koalas gradually become
independent and survive on their own.
