    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.

The impact of fire on two grazed savanna communities in northern Australia

Dyer R. M. and Mott J.J. 1999, 'The impact of fire on two grazed savanna communities in northern Australia', Eldridge E. and Freudenberger D. (eds) People and Rangelands: Building the Future, VIth International Rangelands Congress Proceedings , Townsville, Australia.pp. 268–269.

In this conference paper the authors present the results of a study into the varied effects of prescribed burning regimes on understorey vegetation in the two main grazed pasture (Ribbon blue grass and arid shortgrass) communities in the VRD.

Grasslands of Cape York Peninsula - a fire-dependent habitat

This is a brief article (one page) about the interaction between grasses and woody plants, particularly tea-tree (Melaleuca spp.). It explains with a diagram how different fire regimes can affect the balance between grassland and woody plants.

Modelling the trade-off between fire and grazing in a tropical savanna landscape, northern Australia

This study attempted to model the implications of using fire as a land management tool in grazed areas. The model was developed using a combination of computer generated data and field data.

The results indicate that:

Summary of discussion held about how to best manage wildfire, and how fire can be used as a constructive rather than destructive force in biodiversity conservation.

Overall participants agreed that:

Fire and Population Dynamics of Woody Plants in a Neotropical Savanna: Matrix Model Projections.

Hoffman W. (1999), "Fire and Population Dynamics of Woody Plants in a Neotropical Savanna: Matrix Model Projections", Ecology, 80, pp. 1354 - 1369.

This study was completed in the cerrado savannas of Brazil. It developed a model which aimed to simulate the effects of increased fire frequency on woody plants. The model used information from 5 species (a subshrub, 2 shrubs and 2 trees) using four years of demographic data.

Ecological and economic assessment of prescribed burning impacts in semi-arid pastoral lands of northern Australia

Dyer R., and Stafford-Smith M. (2003), "Ecological and economic assessment of prescribed burning impacts in semi-arid pastoral lands of northern Australia", International Journal of Wildland Fire, 12, pp. 403 - 413.

Pastoral managers in the savanna region of northern Australia are faced with some difficult short and long term decisions about what grasses should be used for – as fodder for animal production, or as a means of maintaining a tree/grass balance with fire.
