Tropical Rainforests
Australia was once a much greener continent covered in lush forests. As
it drifted northwards and climatic conditions changed it became drier
and rainforests were pushed to the wetter pockets that remain in some
areas.
Nowadays there are still fragments of temperate rainforest, mostly in the
cooler, wetter areas of Tasmania and along the east and south-eastern
coasts. The most luxuriant rainforest is to be found in the northern
tropics, where it grows in tiny remnants in the far north-east.
Rainforests were growing here 100 million years ago when Australia was
still attached to its Gondwanan neighbours. Although they cover only
0.001% of Australia's land surface, these very old forests are full of
wildlife, with more animal and plant species than any other Australian
environment.
The rainforest is a place like no other with giant strangler figs, vines, bright green fan palms, and ancient silky oaks. King ferns sprout in the deep shade of the forest
floor and ferns and orchids festoon the trees. |
