Leaf oil chemistry of Eucalyptus nitens and the Tasmanian native eucalypts

Recent media stories have raised interest in the similarity of the leaf chemistry of Eucalyptus nitens to that of the Tasmanian native eucalypts.  The suggestion was raised that a chemical or chemicals leaching from E. nitens plantations may be the cause of toxicity detected by laboratory testing of some foam and surface water samples collected from the George River in North-eastern Tasmania. Two compounds in particular, 1,8 cineole and alpha-pinene that were found in the water samples are major components of the leaf volatile oils of many eucalypt species, including E. nitens.  This raised the question: how similar is the chemistry of the leaves of E. nitens to that of native Tasmanian species?  Brad Potts, Paul Tilyard and Julianne O'Reilly Wapstra decided to find out ...

What's On

CRC Annual Science Meeting

The CRC Forestry's Annual Science Meeting will be held this month, 18-20 May in Fremantle, Western Australia.  The annual event brings together students, researchers, project managers, industry partners and directors for several days of research presentations, research management meetings, student workshops, field trips and networking.  Twenty-seven post-graduate students will be attending a professional development program on Monday and Tuesday that will discuss current issues in forestry, how to maximise the impact that their research makes on the industry, how to write scientific journal articles and how to present their research to a general audience.  For CRC researchers, a workshop on plantation pests will be held before the ASM on Monday 17th May (learn more).  Following the ASM (Friday 21st May) there will be two field trips: one that will provide a whole catchment perspective on managing forests for multiple outcomes; a second tour will cover some of the components contributing to the supply chain of the hardwood plantation sector in WA.  Click here for more information about the ASM and associated field trips.

Plantation Pest workshop

The CRC will be holding a plantation pest workshop as an adjunct to the Annual Science Meeting in Fremantle in May.  The workshop, hosted by Giles Hardy and/or Treena Burgess will be held at Murdoch University on the Monday before the ASM.  The aim is to bring together research groups within the CRC that share a common interest in integrated pest management in temperate eucalypt plantations. The one-day workshop will cover four themes:

1.    Summary of the key regional pest challenges
2.    Current approaches to management (strengths and weaknesses)
3.    Way forward (activities / actions to strengthen current management)
4.    Future issues

What's Been On

Forest planners identify habitat hollows

Last November, Anne Chuter and Amy Koch from Tasmania's Forest Practices Authority (FPA) ran two successful field days for forest planners on the identification of hollow-bearing trees used by fauna and the application of the current Forest Practices Code provisions for the management of tree hollows within coupes. About 25-30 people attended each day, including industry partners, DPIPWE and consultants. Attendees of these field days were given a copy of the new booklet ‘Tree hollows in Tasmania – A guide’ that has been produced by the FPA and the CRC for Forestry. This booklet helps the reader identify hollows, habitat trees and recruitment trees.

Threatened eucalypts featured on ABC Stateline

A team of scientists including two of the CRC's eucalypt genetics specialists, Dr Rebecca Jones and Prof Brad Potts, took ABC TV Stateline journalist Fiona Breen and her film crew into the field to examine the plights of two endangered eucalypts, the Mienna cider gum (Eucalyptus gunnii ssp. divaricata) and Morrisby's gum (E. morrisbyi).  You can view the resulting footage or read the transcript here.

Subproject 4.2.2 Biodiversity outcomes from plantation expansion into agricultural and native forest landscapes

Birds, Bats, Remnant Forest and Tree Plantations

In some areas of Australia, plantation forests have increased the amount of forest cover in the landscape and altered the adjacent habitat surrounding remaining native vegetation. The expansion of the plantation estate has  been mostly onto lands previously cleared for agriculture. Patches of remnant native vegetation that were recently surrounded by pasture are now surrounded by plantation forests. What are the consequences of these changes in forest cover to the bird and bat biodiversity in these landscapes? This is the question that Mayumi Knight, a PhD student at the University of Melbourne, is posing for her PhD studies.  [read more]

Plantations, native remnants and the insects they could share ...

Since 1994, the area of hardwood plantations across Australia has increased sixfold.  The expansion of the plantation estate into ex-grazing land has increased the "edge" area shared between eucalypt plantations and native eucalypt habitats. Native woodlands contain many species of insect that might impact on tree health and productivity if they were to move into an adjacent plantation.  What might be the consequences of this?  Peter Grimbacher (post-doctoral research fellow, University of Melbourne) is leading a collaboration involving other CRC for Forestry entomologists to examine the trends and impacts over the past 16 years ...

Plantations provide positive outcomes for beetle biodiversity

In the Green Triangle region of south-eastern South Australia and western Victoria, much of the remnant vegetation is surrounded by either pasture or newly established blue gum plantations. Chela Powell (PhD student, University of Melbourne) has been investigating whether the establishment of blue gum plantations has had a positive or negative effect on beetle biodiversity ...
