Landline on ABC on Sunday had a feature on the land clearing in Qld plus
another on land restoration via tree planting.
The Qld one had some interesting points by oldies that the natural area
they were in over 50 years ago was few trees plus grasses but woody weed
type trees now have the ground bare of grass cover, result errosion.
Past aborigional burning may have kept the woody weeds and trees to a
minimum but over grazing allowed them to come back as the paddocks are
rested for years. Some have cleared a lot of the tree cover and resown
native + introduced grasses so soil is improved, the properties did look
better after I must
admit. They also carried more stock without over grazing. None of these
had any data on changes to the animals/birds after
clearing but all seemed to call for responsible clearing only. What is
responsible is in the eye of the beholder and how to control for the
best ??
The next progam had Murray catchment properties where trees, replanning
etc had changed marginal properties into viable ones with the return of
native birds never seen before, like Lanark.
The real area where land restoration is in the southern states where
clearing has caused a major decline in soil viability. Where has the
Telstra monies gone ??
Cheers Chris
