Australian landscapes from eocene to anthropocene

The 65-million-year journey from the demise of the dinosaurs to the present day is characterised by changing climes, periods of species extinctions and, finally, the appearance of Homo sapiens. As an island from the start of this period, Australia’s landscapes were isolated from the rest of the world and to this day are characterised by a unique biodiversity. Since their arrival, First Nations peoples have somehow understood this special landscape, living in conformity with it, changing along the way as the climate and landscape changed. That all changed with the arrival of people from Europe, who were more familiar with a weedy landscape recovering from deep glaciation. Over the last 250 years, a lack of understanding of the uniqueness of the Australian landscape, and of First Nations connections with that landscape, has wrought both biological and cultural disruptions. Looking ahead, more conversations between all Australians on how to manage this country into an uncertain future, respecting the range of world views that exist, and rebuilding a viable biocultural diversity, remains a significant but achievable challenge.
