Current projects
1. Multi-scale analysis of patterns in ecological processes in relation to fire regimes (Bushfire Cooperative Research Centre, Programme B, Project 4.2).
Fire is a key element of many Australian environments – over time it shapes and structures the landscape at multiple scales. The resulting patchiness of vegetation and soil properties affects ecological processes such as the cycling of carbon, nutrients, and water, as well as the propagation of future (fire) disturbances. These feedback mechanisms provide the system with memory, which is a key ingredient for self-organisation towards a robust landscape mosaic. Most research on self-organisation processes in landscape systems has been via modelling studies – far less via observations in real landscapes. In this project we aim at underpinning the concept of self-organising landscape systems by process-pattern measurements and simulation experiments, and at exploring its implications for ecologically sustainable fire management. Fieldwork is conducted in the forested landscapes of SW Western Australia and the arid grassland and shrublands of the Pilbara region of Western Australia.
2. Fire management of complex rehabilitated forests - quantifying and understanding spatial variablilty of forest structure and fuels (Australian Research Council - Linkage Grant)
Fire can be a risk to human and ecological values, and its management complicated by landscape fragmentation. Improved management is dependent on understanding factors that determine fore behaviour and its ecological consequences. We will investigate fuel distribution, fire behaviour and vegetation recovery across a complex forest mosaic. Our objective is to understand how fine-scale fuel patterns and vegetation characteristics evolve in rehabilitated eucalypt forest (on a bauxite mine) and how these patterns affect subsequent fire behaviour and impacts. This research will define the way prescribed fire is used to integrate young rehabilitated forest into management of broader landscape and develop cost-effective tools for fire management.
