16 December 2015, CSIRO ECOS CSIRO and Ngadju tackle bushfires in the Great Western Woodlands. Old and new ways of fire management are coming together to help protect one of the most unique woodlands on the planet. Members of the Ngadju community began working with CSIRO about four years ago to help prevent fires in the Great Western Woodlands (GWW) in south-western Australia. The GWW is the largest remaining tract of dry climate woodland on Earth. The region receives as little as 250 mm rain per year. Owing to the variable rainfall and lack of readily accessible groundwater suitable for livestock, much of the region has remained virtually unchanged since European settlement. However during recent years, the GWW has experienced an increase in the frequency of large, intense wildfires causing fire-sensitive old-growth woodlands to be lost at an alarming rate. Leslie Schultz from Ngadju Conservation believes climate change is contributing to the increase in fires. “The heat we get now is harsher and when it does come, there’s less rain—this can only spell trouble for the Woodlands,” he said. Les said the relationship between Ngadju and CSIRO was born from his own experience of “burning off country”—something he learnt from his elders. “We need to control the country so it doesn’t control us,” Les said. “We want to incorporate our traditional land management methods. We managed our country not with rakes, shovels and bulldozers but with fire.” The insight and the benefits of utilising Indigenous fire knowledge was no more apparent than during the recent devastating bushfires in Western Australia. These fires damaged large areas of the GWW directly. In the nearby community of Esperance one fire led to the loss of four lives, with reportedly more than 280,000 hectares of farmland burnt, along with houses, sheds, machinery and almost 5,000 livestock. Ngadju mobilised to help fight these fires and provided valuable insight into the current landscape. They also currently operate a small ranger team in the GWW and undertake a mix of contract land management. Read More here

25 November 2015, The conversation, Ashes to ashes: logging and fires have left Victoria’s magnificent forests in tatters. In February 2009 the Black Saturday bushfires swept through the Mountain Ash forests of Victoria, burning 72,000 hectares. These forests are home to the tallest flowering plants on the planet, and iconic species such as the Leadbeater’s Possum, Victoria’s animal emblem. In the six years since the fires, we and other scientists have been investigating how the forests have recovered, summarised in our new book. This research was in turn built on 25 years of research before the fires. There’s some good news and some bad. The forests and their inhabitants have a remarkable capacity for recovery from natural disturbances like fire. However, the forest ecosystem is in a precarious state, largely due to the continuation of Victoria’s logging industry. Winners and losers Some species seemed to fare well after the fires, or even to have benefited from them. In the week leading up to the 2009 fires, 18 Brushtail Possums were fitted with radio-tracking collars, and all were found alive two months later. After the fire, Flame Robins arrived in the forest in huge numbers to take advantage of hunting opportunities in the open burnt forest. The native Bush Rat and carnivorous Agile Antechinus (a minute relative of the Quoll and Tasmanian Devil), were hit hard by the fire. Their numbers were initially severely reduced but then recovered to be equally or more abundant in burnt than unburnt forest within three years. In contrast, other species have struggled in the post-fire environment, such as the Greater Glider and Leadbeater’s Possum. Read More here
15 October 2015, The Conversation, Death of a landscape: why have thousands of trees dropped dead in New South Wales? Trees die – that’s a fact of life. But is the death of an entire iconic landscape of Eucalyptus in the Cooma-Monaro region of New South Wales natural? For over a decade, large stands of Eucalyptus viminalis, commonly known as Ribbon Gum or Manna Gum, have been gradually declining in health, and now stand like skeletons in huge tree graveyards. In our recently published survey we found the affected area to cover almost 2,000 square km, about the size of the area burnt in the devastating Ash Wednesday bushfires in Victoria or more than the area covered by the 2003 Canberra fires. Within this area, almost every Ribbon Gum is either dead or showing signs of severe stress and dieback, with thinning crowns full of dead branches. Other tree species seem to be surviving, but this smooth-barked gum with its characteristic ribbons of peeling park, once the dominant tree of the Monaro, now seems set to disappear from the landscape.

23 July 2015, The Conversation, Native forests can help hit emissions targets – if we leave them alone: The debate over native forest logging has been sparked once again, partly by the government’s successful push for wood burning to be included in the revamped Renewable Energy Target. However, the disagreement over the best way to manage Australia’s 9.4 million hectares of public native forest is thrown into sharp relief by analysis showing that ending native forest logging, and completing the the industry’s shift into plantations instead, would get Australia much of the way to its greenhouse gas emissions reductions target. Analysis done using the Australian government’s public native forest model suggests that stopping all harvesting in the public native forest estate would generate in the order of 38 million tonnes of potential credits (that is, the equivalent of 38 million tonnes of carbon dioxide emissions avoided) each year in the short to medium term.
While this is the technical capacity, the Kyoto Protocol’s rules cap credits from forest management at 3.5% of base-year emissions, or around 15 million tonnes of CO2 equivalent per year. So if Australia ratifies the second commitment period of the Protocol, which runs from 2013 to 2020, the cap would limit forest management credits to 120 million tonnes of CO2 equivalent over the commitment period. The Australian government’s latest emissions projections estimate that, in order to meet its 5% emissions-reduction target in 2020, Australia has to reduce its emissions by 236 million tonnes of CO2 equivalent over the second commitment period. This means stopping harvesting in public native forests could provide 51% of the abatement task to 2020. Read More here
