I am a landscape ecologist whose major interests are teasing apart aspects of biodiversity, such as diversity measures and functional traits. I also have major research interests in vegetation classification. My current research focuses on both arid landscapes, wetland systems and coastal headlands. While I started within plant systematics my interests were still in understanding geographic differences. My publications topics are broad and include systematics, biomass, sociology and both flora and fauna but usually in some way combine biogeographic aspects of diversity, climate, geographic range and functionality. I have conducted vegetation survey and mapping across the entirety of NSW and parts of Qld and placed over 25,000 survey sites. I have currently authored over 240 reports and publications of which 95 are peer-reviewed journal publications. I am an associated editor on the international journal of vegetation classification Phytocoenologia and previously for Pacific Conservation Biology. I have numerous roles on committees including secretary of the international Vegetation Classification Working Group, the Northern Tablelands Regional Advisory Committee and the technical sub-committee for the Saving Our Species/Landscape Species/Data Deficient Species programs for the NSW Environmental Trust.
