After spending too much time on them, my comments on the Murrah flora reserves final draft working plan, have been dutifully submitted. Based on experience, there is no certainty that anyone in the OE&H will read them. Should they be read, there is somewhat less certainty anyone in the OE&H will understand them and some what less certainty they will be acted on.
While it would be reassuring to think the proposal for adaptive management in the working plan actually meant something. The impediment to adaptive management, as pointed out in ‘Options forestry-acting on uncertainty’ (Bormann & Kiester 2004) is clearly associated with ‘spurious certitude’.
That is, the NSW government agencies all believe they know what ecologically sustainable forest management is and that’s what they do, so there is no need to learn from experience or change anything. Then there is the native forest logging industry, that, from the governments perspective, has to be supported at any societal or environmental cost.
For those who feel this approach is reckless, at best. The ultimate outcome could be disastrous.
Recently published in the journal Nature is paper titled “Europe’s lost forests: a pollen-based synthesis for the last 11,000 years“. According to the paper Europe’s forests reached their maximum extent between 8000 and 6000 years ago and then began to reduce. However, sometime after 4000 years ago the rate at which the area of forest reduced, greatly increased.
The reduction was greatest in southern Europe and an example given is Lake Dojran, between Macedonia and Greece. Here, pollen retrieved from the lake pointed to a large erosion event some 3200 years ago. At the time people had been clearing the temperate forests for agriculture and there was an increasing demand for timber, to build boats. Soils had been depleting for some time, but the large erosion event topped it off.
In a Sydney Morning Herald article one of the paper’s authors, Mr Rothacker indicated ” . . . the link between soil health and agricultural output would have shown up rapidly.”
He went on to add – “Without soil, you basically lack the key component in the eco-system to grow food,” he said. “If you don’t have mature soils any more, you can’t grow that food and you can’t supply a large population.”
