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.

Sharp D.R., and Bowman D.M.J.S. (2004), "Patterns of long-term woody vegetation change in a sandstone plateau savanna woodland, Northern Territory", Journal of Tropical Ecology, 20, pp. 259 - 270.
In this study a time series of aerial photographs were used to assess woody vegetation change at 122 locations on a sandstone-plateau woodland in the Victoria River Region, Northern Territory.

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.

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:

Morton S.R., and Andrew M. (1987), "Ecological impact and management of fire in Northern Australia", Search, 18, pp. 77 - 82.
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:

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.

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.
