CSIRO on the Willow Warpath

Just read this in this mornings paper: ... 19l88.html

They argue that natives will shade the same amount of open water (from evaporation) whilst consuming far less water. I hope they do not advocate removing the willows before the desired native canopy is established???

good point.
Also,If this wet continues in the Eastern half of Australia, we will be needing all the root systems there are to keep any riverbanks and soil intact.
It's got me buggered how anyone can accurately measure evaporation etc under trees on a riverbank. Wouldn't you need decades of data??
The whole argument about willows is shaping up,like the one about Black Cockatoos. Pine tree removal was considered the done thing in the glossies' habitat, until it was found that they were feeding on pine cones....

Farmer questions willow removal policy.

The recent floods across much of SE Australia has brought greater attention to this Federally funded myopia.

See ... 45783.aspx

The CMA encourage this policy but note in the article they shifted any blame to the local council.

Rather thn an illustralion of "BUREAUCRATS CONTINUING TO MANAGE FAILURE" this is simply an example of human nature we see again and again after every flood, bushfire and other natural disaster. People have short memories and after decade of drought little though was put into possible impacts of flood, and in hindsight, innapropriate techniques to achieve the aim of the program were adopted.

And unfortunately it seems it is human nature not to learn from thse types of mistake.
