Tree improvement and seedling supply<br />
Maximising the production of high quality<br />
sawlogs, and associated products, from<br />
plantations through genetic improvement,<br />
pruning, thinning and fertilising to improve<br />
growth and wood quality.<br />
Completed the FWPA-funded Rotary-Peeled Veneer study which provided<br />
baseline data on veneer quality and plywood properties of fibre-managed<br />
plantation E. nitens grown in <strong>Tasmania</strong>. It also identified genetic parameters that<br />
affect quality of rotary-peeled veneer and plywood to guide selection of families<br />
for future breeding programs.<br />
Established 3 new genetics trials (2 E. nitens progeny trials and 1 E. nitens<br />
demonstration-of-genetic-gains trial).<br />
Established a new E. nitens seed orchard.<br />
Modelling work by collaborators shows that DNA markers can be used in<br />
genetic analysis to improve the predictions of genetic values related to wood<br />
quality. Commenced the FWPA-funded Hottest 1000 project to look for more<br />
DNA markers in both E. nitens and E. globulus.<br />
Ongoing collaboration with Private Forests <strong>Tasmania</strong> on eucalypt species trials<br />
to test suitability for lowland cold and dry environments in <strong>Tasmania</strong>.<br />

Eucalypt plantation silviculture<br />
Maximising the production of high quality<br />
sawlogs, and associated products, from<br />
plantations through improved silviculture.<br />
Initiated ‘commercial’-scale processing study in collaboration with Britton<br />
Timbers Ltd to explore impact of sawing and drying schedules on product<br />
recovery, utility and value from plantation-grown E. globulus and E. nitens.<br />
A second major trial investigating the processing requirements and wood<br />
quality outcomes for plantation-grown E. nitens demonstrated that alternative<br />
sawing strategies, in combination with appropriate reconditioning, can<br />
effectively eliminate surface and internal checking.<br />
Further modelling of alternative thinning regimes for hardwood sawlog<br />
production and preliminary operational guidelines.<br />
Establishment (in collaboration with District staff) of 400 ha of demonstration<br />
sites for alternative thinning regimes.<br />
Completion of Derwent project (coupe analysis and development of coupe<br />
management plans).<br />
