Key threatening process nomination - Contemporary fire regimes resulting in the loss of vegetation heterogeneity and biodiversity in the non-fragmented landscapes of northern Australia

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)

Application of NDVI for predicting fuel curing at landscape scales in northern Australia - Can remotely sensed data help schedule the timing of fire managment operations?

This paper considers the use of satellite data to assess fuel characteristics and plan fire management activities. (Allen et al., 2002)

Bushfires CRC Fire Note - Measuring responses to fire regimes in Northern Australia

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.

What happens to individual animals during a prescribed burn in Northern Australia

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)

Savanna fires 1997 to 2005

Mapping fire scars (burnt areas) using satellite technology provides a very useful record of the effects of fire, particularly across the northern landscapes. This slide show illustrates the the extent and distribution of early and late season fires across Australia's tropical savannas.
