It is extremely disappointing that the Government’s advice is being restricted to the view of Professor Mackey and his fellow wild country activist academics. This is a mistake that has already been done in the final report of the Garnaut Climate Change Review that states on page 165 “Mackey et al. estimate that the eucalypt forests of south-eastern Australian could remove about 136 M t CO2-e per year (on average) for the next 100 years. This estimate is premised on several key assumptions, including cessation of logging and controlled burning over the 14.5 million hectare study area.”
This estimate is based on Greens senator Christine Milne’s philosophy that our forests are a carbon bank, and totally ignores wild fire. Such a fallacy is shown in the subsequent article published by the PNAS that claimed the carbon findings were based on E. regnans forest in the O’Shannassy catchment of Victoria’s Central Highlands, 53 sites within a 13,000-ha catchment.
But the PNAS publication also states “In February 2009, extensive areas of the O’Shannassy Catchment and elsewhere in the Central Highlands of Victoria were burned in a major conflagration”. An event most of us know as the tragic Black Saturday bushfires that not only destroyed the forests but many human lives and families.
Surely it is time that experts not associated with the Greens or their splinter groups be invited to brief the ALP and the non green members of the minority government.
Perhaps it is also time that the ANU academics get a lesson in the difference between deforestation and forestry as the PNAS paper starts with “Deforestation currently accounts for _18% of global carbon emissions ... Reducing emissions from deforestation and degradation (REDD) is now recognized as a critical component of climate change mitigation.
Forestry (harvesting and regeneration) is a long term carbon sink, with timber products able to both store carbon and substitute for other material with a larger carbon footprint.
