Australian Rainforests: Islands of Green in a Land of Fire
Why do Australian rainforests occur as islands within the vast tracts of Eucalyptus? Why is fire a critical ecological factor in every Australian landscape? What were the consequences of the use of fire by the Ice Age colonists? In this original and challenging book, David Bowman critically examines all hypotheses that have been advanced to answer these questions. He demonstrates that fire is the most critical factor in controlling the distribution of rainforest throughout Australia. Furthermore, while Aboriginal people used fire to skillfully manage and preserve habitats, he concludes that they did not significantly influence the evolution of Australia's unique flora and fauna. This volume, the first comprehensive overview of the diverse literature on this topic, solves the puzzle of the archipelago of rainforest habitats in Australia. It is essential reading for all ecologists, foresters, conservation biologists, and others interested in the biogeography and ecology of Australian rainforests.
What people are saying - Write a review
This is a politically correct book that totally rules out mans impact through fire stick farming and hunting on the flora and mega fauna of the Australian continent. Mans arrival 40,000 years ago coincides with the mass extinction of megafauna,the introduction of the destructive dog or 'dingo' and the gradual decline of temperate Araucaria forests and proliferation of the fire loving Eucalyptus. Its data has been skewed toward the authors views and no mention of mans impact is brought up. Definitely not recommended reading for truth seekers and realists. This publication is fantasy of the worst kind.
