SST Biodiversity
Document the biodiversity impacts from the
range of silvicultural treatments available for
harvesting wet eucalypt forests.
Completed annual bird and ground beetle surveys of the SST in the control
and treatments that have reached 10-year post harvest (CBS + UI 1 and 2,
DRN-2).

Forest influence
Test the nature and magnitude of forest
influence into harvest areas of old clearfells, and
how influence effects vary dependent on the
successional stage (wet sclerophyll versus mixed
forest) of the adjoining retained forest.
Liaised with overseas collaborators to participate in global meta-study to
measure forest influence.
Selected suitable sites and established 5 plots to measure forest influence
in each of three clearfell, burn and sow age classes (5-10 year-old, 22-28
year-old, 39-45 year-old).
Tested sample of TFIC insects for their suitability for DNA barcoding.
2. Sustaining jobs for current and future generations
2.4 Plantations
Establish and manage plantations
to maintain timber supply levels
to industry.

Dead branch defect in pruned plantations
Understand the risk factors associated with
branch trace defects developing after pruning
dead branches and develop appropriate
mitigation measures.
Amended pruning prescription to reduce likelihood of branch trace defect
following pruning of dead branches.
