Professor David Lindenmayer from The Australian National University (ANU) said governments needed to act to protect the remaining forests and to protect the Leadbeater’s possum and other species.
He said the 2009 Back Saturday bushfires had wiped out 42 per cent of habitat and reduced the population from about 5,000 to 2,000 animals.
“Unless conservation areas are expanded to cover almost all remaining Mountain Ash forests, the critically endangered Leadbeater’s Possum will become extinct and other species like the Greater Glider will continue to decline,” said Professor Lindenmayer, from the ANU Fenner School of Environment and Society.
“Conserving these forests will benefit many species. If logging continues the Leadbeater’s Possum will be the first to become extinct, but it would not be the last. Think of it as the canary in the coal mine.
“When the current Regional Forest Agreements expire at the end of this year, the Victorian and Federal Governments need to act to bring these areas into conservation reserves.”
He said half of the greater glider population in Mountain Ash forests has also been lost in the past decade.
Professor Lindenmayer has studied the Mountain Ash Forests for more than 30 years, published more than 200 scientific studies and written eight books on the topic.
The research is part of the Australian Government’s National Environmental Science Program and was carried out by researchers from The Australian National University and The University of Melbourne.
Dr Chris Taylor from The University of Melbourne led the spatial analysis which identified the important areas for the Leadbeater’s Possum.
“The existing conservation reserves only cover 30 per cent of ideal habitat. On their own they are inadequate to conserve the species,” Dr Taylor said.
“Some important areas currently fall outside of conservation reserves and are open to logging. It is really important that these areas are brought in to conservation reserves.”
Professor Lindenmayer said native animals in the Mountain Ash forest require large old trees over 190 years for tree hollows, which they need to breed and survive. He said only one per cent of Mountain Ash forest was old growth, compared to 60 per cent 150 years ago.
Professor Lindenmayer said studies had found the value of water and tourism from the forests also outweighed the value of logging, while logged forests have more frequent and intense fires, due to the debris and the nature of young forests.
“Every angle you take points to the same conclusion, there is no viable long-term future for logging native Mountain Ash forests,” he said.
“The best option for everyone including forestry workers is to immediately begin transitioning to all timber production coming from plantations.”
The research has been published in the PLOS ONE journal.
