My research interests include threatened flora management, fire ecology, plant-animal interactions and invasive species. Specific areas of research include understanding spatial patterns of distribution of threatened flora and threats in south-western Australia, changes in the composition, function, structure and fuel of vegetation communities with time since fire, patterns of fire across time and space and effects of fire on animal communities. This research has been conducted primarily in dry to semi-arid Mediterranean-climate landscapes across a variety of vegetation types.
