9 September 2016, The Conversation, EcoCheck: the Grampians are struggling with drought and deluge. Our EcoCheck series takes the pulse of some of Australia’s most important ecosystems to find out if they’re in good health or on the wane. The Grampians National Park is a large conservation reserve, sprawling across 168,000 hectares embedded in western Victoria’s agricultural landscape. With a rich cultural heritage and regionally important flora and fauna, it is a hugely significant area for conservation. But in recent years it has been subjected to a series of major wildfire events, a flood, and long periods of low rainfall. Our research shows that this has sent small mammal populations on the kind of boom-and-bust rollercoaster ride usually seen in arid places, not temperate forests.The fire and the flood We began studying the Grampians in 2008, investigating how small mammals had responded to a catastrophic wildfire that burned half of the national park in 2006. What started as a one-year study has turned into a long-term research program to investigate how the past few years of hypervariable rainfall and heightened bushfire activity have affected the animals that live in the park. Fortunately (for our study, at least), the beginning of our research in 2008 was in the middle of a long run of very poor rainfall years, as the Millennium Drought reached its height. The drought was broken at the end of 2010 by the Big Wet, which led to well-above-average rainfall and floods in the Grampians. But soon after, rainfall rapidly dipped back to below average. It has stayed there ever since. We also saw two more major fire events, in 2013 and 2014, which together with the 2006 fire burned some 90% of the Grampians landscape. Read More here
6 September 2016, The Guardian, Asian typhoons becoming more intense, study finds. Giant storms that wreak havoc across China, Japan, Korea and the Philippines have grown 50% stronger in the past 40 years due to warming seas. The destructive power of the typhoons that wreak havoc across China, Japan, Korea and the Philippines has intensified by 50% in the past 40 years due to warming seas, a new study has found. The researchers warn that global warming will lead the giant storms to become even stronger in the future, threatening the large and growing coastal populations of those nations. “It is a very, very substantial increase,” said Prof Wei Mei, at the University of North Carolina at Chapel Hill, who led the new work. “We believe the results are very important for east Asian countries because of the huge populations in these areas. People should be aware of the increase in typhoon intensity because when they make landfall these can cause much more damage.” Typhoons can have devastating impacts in east Asia. In 2013, typhoon Haiyan hit the Philippines, killing at least 6,300 people and affecting 11 million. Typhoon Nina struck China in 1975, dumping 100cm of rain in a day and leading to 229,000 deaths and 6m destroyed buildings. Last week typhoon Lionrock left 11 people dead in northern Japan and caused power blackouts and property damage, while in July typhoon Nepartak hit Taiwan and China, killing at least nine people and leaving a trail of destruction.
