Integrating forest values with landscape management

himlal baral thumb

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.

What's Been On

Clarke Medallist profiled by ABC's Stateline

ABC Filming BradLike a pebble thrown into a pond, the after-effects of Brad Potts' prestigious Clarke Medal award (see article in Biobuzz 8, April 2009) are still being felt across Tasmania.  ABC Stateline's TV crew visited the UTAS School of Plant Science  in August to profile Brad Potts and his research.  Brad, being 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 the transcript from ABC Stateline]

Mammalogical Congress

In August, UTAS PhD student Helen Stephens attended the 10th International Mammalogical Congress in Mendoza, Argentina. The congress is held only once every four years and this was the first time it had been hosted in South America.  In the lead up to the conference Helen spent a week in the Sierra de las Quijadas National Park, in a desert north-east of Mendoza, assisting with "fear" research in, among other things, armadillos and strange long-legged rodents.

When the going gets tough, the cutting grass gets going!

bb10-styx-overview-thumb­­Liam 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!

­Subproject 4.2.3 Biodiversity value of coarse woody debris

Regeneration time is critical for maintenance of cryptogam biodiversity

Bindi_thumb2­

­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.

Tree ferns go AWOL

bb10-dismal-swamp-thumbWhilst the resilience of tree ferns is probably no surprise to most (as they’re often among the first signs of green returning to a logged coupe), you may be surprised by just how much they move around during a logging operation. Researchers at the Forest Practices Authority have found that 60-70% of the ‘tagged’ ferns in their monitoring plots went missing, never to be seen again. Nina Roberts (Forest Practices Authority) reports ...

Subproject 4.2.6 Management of the risk of gene flow from eucalypt plantations

New trials test fitness of exotic hybrids

bb10 exotic hybrids thumbShining 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 ...
