G'day John,
I think you will find that land clearing in Queensland has peaked
[probably in the 1999-2002 when there was a lot of clearing in
anticipation of the native veg reg], so the first sentence in item 4
may not be strictly correct as currently worded ...
Regards, Laurie.

Hi guys,
Here are my 5 significant facts for the Einstein Factor web-page.
4. Since the mid-1990s, the rate of land clearance in Australia has
been increasing. Estimates indicate that about 470,000 hectares (ha)
of land were cleared in 1999, around 90% in Queensland. Land clearance
is a major threat to many Australian birds.
