Plantation impacts on biodiversity
A
large proportion of Australia’s million hectares of
industrial eucalypt plantations have been established on what was
previously agricultural land, and significant amounts of remnant
native vegetation is now embedded within plantation estates. Such
rapid landscape change across Southern Australia has generated
significant industry, community and scientific interest in how
biodiversity values are affected by forestry operations in these
plantation landscapes. Dr Peter Grimbacher has produced a CRC
report that examines the broad impacts on biodiversity of
plantations across southern Australia, incorporating information on
the full life-cycle and variety of plantation operations, the
land-use history and landscape context; he has also tested the
various perceptions held by the general public concerning
biodiversity and eucalypt plantations. You can download
the public CRC report here.

CRC Annual Science Meeting
The final CRC Forestry Annual Science Meeting will be held at
The Mantra Hotel, Mooloolaba, Queensland, Monday 5th –
Thursday 8th March 2012. In addition to being a valuable
networking opportunity for staff and students alike, the ASM puts
everyone’s research efforts into perspective by providing a
broad overview of the research that has been taking place across
the CRC. On the Monday of the ASM, Merv Shepherd (SCU; subproject
4.2.6) is hoping to hold a workshop on the risk of gene flow out of
plantations into native forests. Watch your email

Tasmania remains free of the disease. We would like to

and what to do if they find some in Tasmania. [view poster] [view reference card]
Subproject 4.2.1 Biodiversity benefits of alternatives to
clearfelling
Variable retention report
AN FWPA report on using variable retention (VR) silviculture to
balance forestry with biodiversity is now available. VR was
originally developed in the Pacific North West (PNW) of USA and
Canada as an alternative to clearfelling and other traditional
silvicultural systems, to improve biodiversity and social
outcomes. As VR has recently been implemented in wet
old-growth forests in Tasmania, and there is scope for broader
implementation in Tasmania and mainland Australia, insights from
the PNW about operational experience, research, adaptive
management, and efforts to improve relationships between the timber
industry and environmental groups are of broad relevance to forest
management in Australia. Click here to read the FWPA report.

Subproject 4.2.2 Biodiversity outcomes from plantation
expansion into agricultural and native forest landscapes
Are insect attacks on Eucalyptus plantations a
worsening problem?
Over the past few decades, the plantation area of Eucalyptus
globulus and E. nitens in southern Australia has
increased considerably, leading to concerns that there could also
be an increase in plantation damage by insect herbivores. The good
news is that there is little evidence to suggest that this has
occurred. Dr Peter Grimbacher (UMelb) is the chief author of a
multi-region spatio-temporal review of southern Australian
plantation pests. You can download the pdf of the CRC
technical report here.
Is there life for a conservation biologist after their
PhD?
Chela Powell, who completed her

Understanding forest carbon dynamics in Tasmania’s wet
forests
The
distribution of carbon in the world’s ecosystems plays an
important role in the Earth’s climatic system. Forest
landscapes make a substantial contribution to these carbon stocks,
but relatively little is known about carbon dynamics of Australian
forests. Ian Riley recently received a Tasmanian Graduate Research
Scholarship (TGRS) and a Forest and Wood Product Association (FWPA)
top-up scholarship and project funding to undertake PhD research on
carbon dynamics of Tasmania’s wet forests. [read more]

Subproject 4.2.7 Management of genetic resources
Stringy bark diversity study winds up
Stringy bark,
Eucalyptus obliqua, is one of the most important forestry
species in Tasmania. The resowing of coupes can require the
use of off-site seed when seed is not available from the harvested
coupe. Justin Bloomfield has been studying the patterns of
molecular genetic variation in E. obliqua to determine if
there are underlying patterns of genetic diversity in native E.
obliqua gene pools across Tasmania that need to be taken into
account when transferring seed between seed zones. [read more]
Racial variation in Eucalyptus nitens reviewed
Eucalyptus nitens
(shining gum) is the most widely planted temperate hardwood species

ARC Discovery grant will extend browsing research
Dr Julianne O’Reilly-Wapstra was recently awarded an ARC
Discovery grant in association with Assoc Prof Joseph Bailey and Dr
Jennifer Schweitzer (who recently returned from Tasmania to
University of Tennessee, USA). The project 'From genes to
ecosystems: does genetic divergence in eucalypts alter biodiversity
and ecosystem function?' will use a dominant tree species of
south-eastern Australia to examine how genetic based variation in
its traits influences community organisation, biodiversity and
ecosystem processes. Outcomes from the research will be important
for responding to an uncertain future environment and maintaining
the services that ecosystems provide. The project will allow
Julianne to continue her research into the interactions between
mammal herbivores and eucalypts beyond the current CRC.
Congratulations, Julianne!
