Fire regimes and environmental gradients shape the distribution of forest wildlife KEY MESSAGES: Important insights can be gained by modeling how fire regimes, not just fire events, influence biota in forests Management of fire regimes needs to be complemented by an understanding of the underlying environmental gradients and key elements of habitat structure that influence […]
Fire in the foothills
Fire management for asset protection and the environment Reducing fuel around assets is considered a good hazard-reduction strategy, however, a more effective approach may be to burn for a mosaic throughout the ecosystem. This may reduce the overall fuel of the system, as well has have added benefits for the environment. Land managers and scientists […]
Understanding how pyrodiversity begets biodiversity Key messages: Pyrodiversity describes the variation in the time between fires, their severity, size and patchiness New work is advancing our knowledge of the connection between pyrodiversity and biodiversity but there is a need to further develop approaches that are better tailored to local conditions All around the world fire […]
The peat swamp forest in the south of Kalimantan is an unusual ecosystem that is home to many unique or rare species such as orangutans. It consists of diverse range of tropical trees standing on a layer of peat up to10-12m deep. The peat is partly decayed and waterlogged plant material, and it in turn […]
State-wide percentage targets for planned burning are blunt tools that don’t work Fire profoundly influences human health, the economy and wildlife. In Victoria, for instance, bushfires have burned more than one million hectares since 2009, claiming 178 lives and more than 2,300 homes, and causing more than A$4 billion in social, economic and environmental costs. […]
Using genetic info to better manage biodiversity in a changing world Environmental disturbances range from big events like bushfires, floods and volcanic eruptions to more mundane processes like a boulder being turned over on wave-pounded rocky shore. Ecologists have long realised that disturbance underpins the dynamics and diversity of many of the ecosystems of the […]
The gregarious Carnaby’s cockatoo (Calyptorhynchus latirostris) are such a common sight in Perth that it is easy to forget they are endangered, and that the urban and agricultural expansion of south-western Australia has removed the bulk of their habitat. How we manage their remaining habitat will have important consequences for the species’ survival.
Be careful when playing with fire. It’s a message politicians know too well and after recent catastrophic wildfires in different parts of Australia they want to be seen as actively responding to the threat. One of the common responses is to raise the level of prescribed burning but what are the benefits and costs of this strategy?
Evidence vs opinion: What really protects houses from wildfires? January saw the publication of a fiery piece of research in PLoS ONE on factors correlating with house loss during the Black Saturday fires in 2009. It was led by EDG researcher Phil Gibbons and was sparked by his interest in the claim and counter claim that followed the catastrophe. […]
