I know nothing at all about this subject, really nothing. But I found an article in The Global Mail - about Australia's vegetation before European settlement - exceptionally interesting, and so I post a link to it here in case others might be similarly interested. It's about the research of historian Bill Gammage and his book The Biggest Estate on Earth. Gammage argues that there was no wilderness in Aboriginal Australia; wilderness was 'something that Europeans made'. The indigenous people of the continent had for centuries managed the landscape through the controlled use of fire. The article is accompanied by three short videos in which Gammage talks about his work.
