Since there are over 600 different types of eucalyptus trees, the koala should have no trouble finding food. But koalas are picky! They only want certain gum tree leaves to eat. Out of the 600 varieties of trees, koalas will only eat the leaves of about 120 kinds of gum tree. Some are even pickier than that. The koalas of a specific area will only eat about four or five kinds of gum leaves.
They would rather starve than eat the other kinds. Now that’s stubborn! The biggest problem for koalas now is that the brush land in Australia is being cut down. Towns and cities are pushing farther into the brush. Since many koalas live there, they are losing their tree homes and the trees leaves that feed them.
