Silvicultural management (pruning and thinning) of eucalypt plantations for high-value timber production
I have a total of 38 years research experience in native forest, plantation forest, and agriculture systems.
Much of my research has been on tree nutrition and growth & yield in relation to site (e.g. soil nutrient availability, water holding capacity, salinity) and management (e.g. establishment/regeneration, silviculture) factors in forests and plantations.
My research aims to improve primary industry and natural resource management outcomes, and necessarily in doing this engage with and communicate to stakeholders and end users on scientific, technical, applied, and policy matters. My senior roles have required setting research priorities, directing and leading multi-disciplinary research teams, development of resources to support research, and the associated management responsibilities.
