The Wallace Line
English naturalist Alfred Russel Wallace observed for 8
years the birds on the islands of Bali and Lombok, which
are only 20 miles apart.
He found that the birds on Bali are similar to
those in Java, mainland Malaysia, and
Sumatra.
The birds on Lombok were similar to those on New Guinea
and Australia.
He drew a line called now “The Wallace
Line”
When Pangaea broke apart – Australia, New Zealand, and
other islands became isolated. The plant and animal life
that evolved there is unique.
The region has rich fisheries and fertile
volcanic soil.
Rubber tree plantations are important in some countries.
