My current research interests include landscape revegetation and ecosystem restoration; the environmental impact of wild dog control in temperate wilderness and agricultural landscapes; the nature, value and assessment of ecosystem services; invasive native scrub: soil function, erosion, management and biodiversity correlates; sustainable farming and grazing systems; the role and management of biodiversity in production landscapes; tree–grass interactions; fire and protected area management; ecology and management of plant and animal communities; and environmental dispute resolution. Part of my time is committed to the Invasive Animals CRC and the CRC for Spatial Information.
