This project aims to establish the scientific basis for silvicultural treatments of eucalypt plantations for clear wood production. While eucalypt plantations in north-eastern NSW have dramatically increased in recent times, the knowledge base for the production clear, branch-free wood from the tree species used does not exist. A physiological, mechanistic understanding of crown and canopy dynamics as well as branch shedding will form the scientific foundation for stand manipulations such as pruning and thinning to enhance wood quality. Project outcomes will provide the basis for a stand management simulation model for the most important eucalypt species.Read moreRead less
Breeding for resistance: Diagnostic toolkit for predicting variation in plant defence compounds in Eucalyptus. Pulp and timber from plantations are important for Australia's economic and environmental future. However, we must ensure that these plantations are grown sustainably.

Pulp and timber from plantations are important for Australia's economic and environmental future. However, we must ensure that these plantations are grown sustainably. One area of concern is the current reliance on pesticides to control herbivores of plantation eucalypts. The work proposed here aims to use existing ecological findings together with early access to the genome of Eucalyptus to develop ways of using the natural resistance of Eucalyptus as an alternative to chemical pesticides. The work will also help us to understand how eucalypts produce the distinctive odours that are so characteristic of Australian landscapes.Read moreRead less

Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity & distribution of salt-tolerance. This project is the first to use DNA sequences from thousands of species to understand the evolution of salt-tolerance in order to provide the foundation for the development of new crop varieties, selection of species that can be developed for bioremediation, and identification of traits that will be profitable targets for breeding programs.

The project plans to develop a new understanding of the capacity of forests to increase moisture recycling, which enhances cloud and precipitation processes and exerts a cooling influence on the land surface. Deforestation and climate change are major global challenges. The role of forests in the carbon cycle is well recognised. Less attention is given to their role in the energy and water cycles, and their capacity to regulate regional climate. The project plans to apply an innovative land use-climate scenario modelling to quantify the impacts of deforestation and afforestation on the climate of northern Australia and south-east Asia under global warming. It also plans to evaluate the capacity of restoring forests to offset regional climate change, to inform regional land use planning and climate mitigation and adaptation.Read moreRead less
