Wanneer is vroeger? Was dat toen Australie nog tegen Antartica aanlag?
The current superdominance of Eucalyptus in Australia may be an artefact of human influence on its ecology. In more recent sediments, numerous findings of a dramatic increase in the abundance of Eucalyptus pollen are associated with increased charcoal levels. Though this occurs at different rates throughout Australia, it is compelling evidence for a relationship between the artificial increase of fire frequency with the arrival of Aboriginals and increased prevalence of this exceptionally fire-tolerant genus.
Van wiki, interessant om te lezen. https://en.wikipedia.org/wiki/Eucalyptus#cite_ref-Hill,_R._S_1994_19-1
In a National Park Service study, it was found that the fuel load (in tons per acre) of non-native eucalyptus woods is almost three times as great as native oak woodland.
Inmiddels misschien te veel non-native eucalyptus woods en te weinig native oak woodland?
