Here is the beautiful sound of the Australian Tropical Rainforest. Click the link above to get a sense of what you are about to enter into!
As you can tell the above photo shows you australia as a whole and indicates the Tropical rainforest in Australia. The dark green shown on the map above indicates the tropical rainforest.
As you can tell, the tropical rainforest spans out across the nothern area of the continent which covers about 90,000 hectares(2). Throughout this blog we will be discussing all 900,000, hectors of the Australian rainforest however we may occasionally get specific and refer to specifically the northeastern region known as Queensland.
Orgin of the Australian Tropical Rainforest
Way back long ago a super continent known as Pagaea split up
into two different continents, one named Laurasia and the other Gondwana. The
continent of Laurasia was later transformed into what we now call Europe, and
North America, while Gondwana took over the southern states such as South
America, Africa, Australia, New Guinea, Antarctica, as well as India (3). As time
passed Godwana broke up int multiple pieces and Australia drifted in isolation
towards Southeast Asaia, it eventually evolved it’s on nature and different kinds
of flora and fauna bean to come into existence. Furthermore animal began to
develop such as the kangaroo and koala. As time passed scientist discovered
that the present flora and fauna in the woodlands of Australia had essentially
evolved from an original rainforest stock (3). The tropical rainforest are believed
to be the oldest in the world. According to scientific evidence the tropical rainforest
of Australia had survived in “refugia" for millions of years, somehow escaping
ice ages, sea level rises, and demolition by volcanic activity (3).
Anthropologist have also recorded a group of people living
around the rainforest in ancient times. They were known as the aboriginal
rainforest people. The aborginals not only had language differences but also
had distinct physical differences (3). Although the abiorgianls settled in the Australian rainforest first it
was not them who explored the jungle but the European settlers. They discovered
sugar cane and timber. The excitement
and curiosity of finding new timber lead the settlers to start cutting down
trees through the rainforest and logging began to a popular practice for the
settlers. in the 1960's and 1970's that biologists began to realize that the
area was fairly significant, and the region began to draw groups of
conservation minded people living on the land.
