­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.

What's on?

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 “inbox” and the CRC members’ website for more information.

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.

Subproject 4.2.4  Tools for monitoring and assessing biodiversity

Live! Beetle website

Beetles play key roles in forest biodiversity and as forest pests.  Recently, the Tasmanian Forest Insect Collection (TFIC)—a satellite collection of the Tasmanian Museum and Art Gallery—went live, thanks to Forestry Tasmania.  The TFIC web-site contains a page for each beetle species, with individual photographs and automatically generated distribution maps.  It is a valuable resource for researchers, forest workers and insect enthusiasts.  [Visit the TFIC website].

Subproject 4.2.7  Management of genetic resources

Stringy bark diversity study winds up

Justin-obliqua-thumbStringy 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.

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!
