This report documents the threats to biodiversity resulting from extensive late dry season fires in northern Australia. It calls for the damaging fire regimes to be recognised as a key threatening process under the EPBC Act. (c. 2007)
Leaflet describing Ken Scott's work at the Territory Wildlife Park, Berry Springs, NT that found that even though plant composition was more affected by rainfall, soil and other environmental factors than by fire, long term fire exclusion was associated with loss of Sorghum Sarga intrans.
This poster describes the fate of Red-backed Fairy-wrens during an early dry season fire. The study showed that nearly all the Fairy-wrens survived, but lost weight after the fire, and needed to expand their home range to take in some unburnt country. (Murphy and Garcia, c. 2007)
This extract from Savanna Burning: understanding and using fire in northern Australia describes the landforms, climate and vegetation communities of the Australian tropical savannas.
This article discusses how changing fire regimes have impacted on bird species across Australia. It recommends the reintroduction of occasional fire into some landscapes, and a return to a finer mosaic of burning to reduce the impact of wildfires by maintaining fire-dependent habitat and protecting fire-sensitive birds. (Olsen and Weston, 2005)
This article discusses the disappearence of Northern cypress pine from areas where there is too much fire. The species needs several years without fire, to germinate from seed, mature and produce seed for the next generation. (Compiled by T. Handasyde, 2005)
Extract from Managing for Healthy Country in the VRD discussing impacts of fire and grazing on native invertebrates, and results of projects at Mt Sanford and Kidman Springs where spiders, ants, beetles and grasshoppers respond in a variety of ways to changes in grazing pressure
This document outlines research undertaken in the VRD to assess the impacts of fire and grazing on native vertebrates. The research suggests that the widespread application of any single fire regime over a large area will lead to a decline in biodiversity, and that a variety of burning regimes across the landscape is desirable.
Patch burning is needed to protect understorey vegetation (from which Common Brushtail Possums obtain water in the late dry season) from extensive wildfires. Clearance of very tall eucalypt forests on aluminous laterite mined for bauxite may also locally eliminate the possum.
Research about the influence of fire on the Carpentarian Grasswren. It covers issues such as why the Carpentarian Grasswren is under threat, how fire affects the Carpentarian Grasswren, the current status of the species, its preferred habitat, and what's being done to protect the species.
