An overview of fire management on Gregory National Park
Northern Territory Parks and Wildlife Commission, August 1994
The Gregory National Park is located 100 km south of Katherine NT and is managed by the Northern Territory Conservation Commission. An overview is presented of the topography, burning practices, fauna and flora of the Park. The Park has a number of problems which result from its reduced usage by Aboriginal people and pastoralists. There are now fewer fires and greater fuel loads, and fire when it does arrive is a cataclysmic event which affects a large area. A fire management strategy is proposed which endeavours to cope with issues of wildfires, public safety and protection of assets. It will aim to deal with the distance and isolation, to produce a fire regime with a variety of fire types which have a variety of intensities according to vegetation type and timing according to the prevailing climatic conditions.

The formation of degraded areas in the dry savannah woodlands of northern Australia
B. J. Bridge, J. J. Mott and R. J. Hartigan
Australian Journal of Soil Research, 21, 1, 91-104, 1983
The perennial tall grass understory of a eucalypt woodland on a commonly occurring red earth (Northcote Principal Profile Form Gn2.11) in northern Australia was burnt during the dry season and subjected to weekly clipping during the following two wet seasons to simulate overgrazing.

Biodiversity and fire in the savannah landscape
R. W. Braithwaite
Springer, 1996
In northern Australia, the present biodiversity of the savannah landscape appears to be maintained by an historic anthropogenic fire regime. It is probable that an approximation of the landscape pattern produced by the traditional aboriginal burning regime maximizes biodiversity through maintaining habitat diversity, savannah patchiness, species diversity and protecting endemic species.
