Eucalyptus spp.

Common names: Eucalypt, gum tree.

There are over 600 species in Australia.  They grow in most landscapes from the cold windy highlands to the dry (semi arid) interior of Australia and in most conditions in between.  They can tolerate a wide range of environmental conditions, however, they can't grow in the highest alpine regions or the arid interior of the continent (except beside watercourses). The occasional tree can be found in the rainforests but this is not common.

 Distribution:

They are predominantly found in a coastal band, 150 to 600 kilometres wide, from the Tropic of Capricorn to South Australia and Tasmania, but they are also found in smaller areas in southwest Western Australia.
