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)

The gradual loss and episodic creation of Palm Cockatoo (Probosciger aterrimus) nest-trees in a fire- and cyclone-prone habitat

This paper presents information regarding the rate of loss of nest-hollows over a long period in the tropics, and a dramatic episode of nest-hollow creation following two tropical cyclones. It discusses the loss of nest-trees owing to fire and concludes that fire management should focus on maintaining adequate recruitment of large trees, which could be affected by excessively frequent burning.

Buffel Grass: both friend and foe

Report from the CRC for Desert Knowledge on the value of buffel grass for production and the negative impacts of buffel grass on the environment. It includes a discussion on the interaction between fire and buffel grass. Landscapes invaded by buffel grass can burn more frequently and at a higher intensity than uninvaded vegetation.

Weed management plan for Gamba Grass, 2010

This Weed Management Plan, produced by the Northern Territory Government, forms part of a strategic approach to gamba grass (Andropogon gayanus) management in the NT, with the overall aim being to mitigate the damage caused by gamba grass in relation to the natural environment, property and infrastructure and public health.

Modelling the rate and pattern of woody thickening in Australian savanna pastures

Modelling of woody thickening in the VRD indicates that thickening is rapid on red soils that are heavily grazed an unburnt, and can be reduced with regular burning and reducing stocking rates.
