Integrating forest values with landscape management
Forests provide multiple ecosystem services and are vital to
human well-being. While the values of ecosystem services (eg,
food, fibre, flood protection, clean water and clean air) have been
recognised widely, they are rarely incorporated into planning and
decision-making. Proper classification, mapping and valuation
of ecosystem services can play an important role in restoration
planning and ecosystem-based management. University of
Melbourne PhD student, Himlal
Baral, has developed a framework for classifying and mapping
ecosystem services for a production landscape.

the generous person that he is, shared the publicity around by
including as many of his team in the spotlight as he possibly
could, with visits to SeedEnergy's Cambridge Arboretum, the UTAS
glass houses, the main eucalypt lab as well as the molecular
lab. [read

Ecological Restoration Conference
A
contingent of eight CRC researchers attended the 19th Conference of
the Society for Ecological Restoration International (SERI) in
Perth Western Australia in August (go to conference website). The conference was titled
"Making Change in a Changing World". As restoration ecology
is a relative new scientific discipline, meetings of this magnitude
are important platforms to assist the restoration community in
defining the principles of restoration, understanding goals and
milestones, debating what ecosystem functions to measure and
closing the gap between the science of restoration ecology and the
practice of ecological restoration.

management research project travelled to Napier in New Zealand to
attend the 2009 annual Australasian Wildlife
Management Conference.
Julianne O'Reilly-Wapstra hosted a symposium entitled
“Mitigating impacts of pest species through non-lethal
management strategies.” Twelve speakers from Australia and
New Zealand (including Julianne) presented spoken papers in the
session. Tim Wardlaw (Forestry Tasmania) presented the plenary
talk, discussing Forestry Tasmania's abandonment of 1080-based
control of marsupial browsing and the challenges of replacing 1080
with an integrated management strategy, charting the course from
policy triggers and research aspiration to operational

Alternatives to clearfelling - comparative study completed
Mark Neyland
who works at Forestry Tasmania is also enrolled as a PhD student at
UTAS. Mark recently submitted his PhD thesis that examined

clearfelling. The study took place over ten years at the
Warra silvicultural systems trial in southern Tasmania. Click

When the going gets tough, the cutting grass gets going!
Liam Hindrum recently
completed his Honours degree at UTAS. After working last
summer for Forestry Tasmania in aggregated retention coupes, Liam
became interested in the effects of mechanical disturbance (eg,
machinery tracks, snig tracks etc.) and burn intensity on the
floristic composition of regrowth and took the opportunity to do an
Honours project on the topic. Among other things, Liam
discovered that cutting grass (Gahnia grandis)
out-competes other plants on compressed earth ... which might
explain why eucalypt trials in southern Tasmania are often such a
nightmare to visit!

Comparative influence of edge type on temperate woodland
function
Tom Wright is
on the verge of submitting his PhD thesis to the graduate studies
office at the University of Melbourne. His research focussed
on the function of temperate woodland ecosystems in plantation
landscapes in the Green Triangle Plantation Region. The main
objectives of Tom's project were to understand how ecosystem
processes - in particular, microclimate, gas exchange and water
relations - at woodland edges function when adjoined by mature
plantations compared to traditional agricultural land.

Regeneration time is critical for maintenance of cryptogam
biodiversity
Belinda Browning
(UTAS) recently completed her Masters thesis on “the
influence of forest age and log decay on cryptogam succession in
wet eucalypt forest following clearfell, burn and sow
harvesting”. Her study of cryptogam succession over time
after first rotation logging suggested that these communities
follow a successional pathway similar to one that would occur after
natural wildfire disturbance. Bindi suggested that successive
harvesting events based on rotations even as long as 100 years
could result in the loss of some cryptogam species from a forest
community. Bindi will be graduating in December -
congratulations, Bindi!

Is there anything in that hole?
Dr Amy Koch (Forest Practices Authority) has been working with
other Forest Practices Officers on the development of a new
approach to the management of the tree hollow resource in areas
covered by the Tasmanian Forest Practices system. This work is
still in the development stage but it is hoped that new guidelines
for forest planners can be finalized in 2010. As part of the
management strategy, Amy has developed a guide ("Tree Hollows in
Tasmania") to help field-workers identify the trees that are most
likely to be used by hollow-dependent species.

Subproject 4.2.6 Management of the risk of gene flow from eucalypt
plantations
New trials test fitness of exotic hybrids
Shining gum
(Eucalyptus nitens) is native to New South Wales and
Victoria but is used widely in Tasmania as a plantation
species. A close relative of Tasmanian blue gum, it is
possible that Eucalytus nitens has the potential to
hybridise with wild populations of native Tasmanian species that
grow in the vicinity of E. nitens plantations. Two
trials will be established in late 2009 to investigate the
viability of exotic E. nitens hybrids.

Subproject 4.2.7 Management of genetic resources
Genetic data reveal taxonomic anomaly
The choice
of genetic material for tree breeding relies on accurate taxonomic
information. Traditional morphology-based classifications of
eucalypts can be misleading, however, because of difficulties in
partitioning taxa that have continuous morphological variation that
has arisen through interspecific hybridisation and/or evolutionary
convergence. Three closely related species of red
mahogony, E. pellita,
E. resinifera and E. scias display
such morphological continuity. Son Le, an MSc student at
Southern Cross University, studied underlying genetic affinities of
these three species and discovered that perhaps they are really
only two species.

Forest giants take refuge
The world famous giant ash, the world's tallest angiosperm,
Eucalyptus regnans, is a bit more delicate than we might
think. It likes quite a lot of water and thrives in wet,
montane environments; it does not cope well with drought or fire;
and unlike most eucalypts E. regnans regenerates mainly
from seed. But in the not-too-distant past, southeastern
Australia experienced a series of climatic oscillations between
warm, wet conditions and cold, arid conditions. So how did
our delicate E. regnans cope with all this climate
change? Paul Nevill, a
PhD student at the University of Melbourne, recently published a
paper explaining how he found the answers in the DNA ...

Tasmanian
blue gum, Eucalyptus globulus, is generally considered to

its close relative, the shining gum (E. nitens).
This has lead to shining gum being planted in preference to blue
gum in many lower altitude areas of high disease risk in
