Eucalypt Woodland in Cape York Peninsula as Habitat for Arboreal Marsupials - Responses of the Common Brushtail Possum

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.

Fire and savanna landscapes in northern Australia: regional lessons and global challenges: Introduction to 5 papers

This paper is the introduction and background to an international conference held in Darwin in 2002. The conference reviewed various aspects of the ecology and management of Australia’s tropical savanna region. The proceedings of the fire element of the conference are summarised in three sections: fire patterns at the savanna wide scale: fire regimes and regional landscape dynamics: and managing fire for desired landscape states.

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.

Seedling establishment in an Australian tropical savanna: effects of seed supply, soil disturbance and fire

In this study the author aims to determine whether seed or site availability are limiting factors for seedling recruitment of Eucalyptus miniata and Acacia oncinocarpa. The study was undertaken in tall open forest, unburnt areas of the Kapalga Research Station. (Setterfield, 2002)

Impact of fire on bellyache bush (Jatropha gossypiifolia) plant mortality and seedling recruitment

This study investigated the efficacy of fire as a control technique for bellyache bush in riparian areas. Although they found the weed was sensitive to fire, the authors stress that fire should be used as one of a number tools in the control of bellyache bush. The authors highlight the need to form an integrated management plan to control both the primary infestation and later seedlings. (Bebawi and Campbell, 2002)

Correlates of grass-species composition in a savanna woodland in northern Australia

The study aimed to determine the relative influence of environmental characteristics including fire on grass-species composition in a savanna woodland in northern Australia. The results demonstrate a complex interplay between bottom-up environmental factors and top-down processes such as fire, as determinants of grass-species composition in tropical savannas.

Variation in the age at first flowering for seedlings of 15 fire-killed shrubs and trees on sandstone outcrops and sand plains in central and north-western Queensland

This paper documents the variation in age at first flowering by 15 fire-killed shrubs of sandstone and sand plain woodlands of central and north-west Queensland. In only two species, Acacia acradenia and Acacia gonoclada, were more than half of the individuals examined beginning to produce seed within 3 or 4 years of post-fire germination.
