Preliminary notice of triennial meeting of the Malacological Society of Australasia entitled Molluscs in Research, Conservation and the Economy. The meeting is to be held on 6 - 8 December 2006 at the University of Wollongong, with two day pre and post conference workshops (4-5th Dec, 9-10 Dec). The objective of this meeting is to bring together students, established researchers, naturalists and members of government and NGO agencies that have an interest in molluscs. The meeting will focus on current research involving molluscs in the Australasian area. Molluscs are the second largest animal phylum and many are ecologically and economically important. They are dominant organisms in marine environments and have suffered more human-induced extinctions on land and in freshwaters than seen in all tetrapod vertebrates. Themes:
· Applied studies (aquaculture, fisheries, parasitology, invasive species)
· Conservation and ecology (including endangered species, indicator species, molluscs in experimental ecology, tracking environmental changes)
· Systematics (including taxonomy, phylogeny, evolution, faunistics, biogeography)
· Genetics and development (population genetics, evolution-development, larval development)

A new journal Charophytes (edited by Michelle T.
Casanova) is dedicated to the promotion of research and communication about
charophytes. Charophytes are macroscopic, green algae common in freshwater
wetlands, ponds, dams and saline and esturine lakes. They are widely distributed
throughout Australia and are excellent colonisers of temporary wetlands. They
have dessication resistant spores which create persistent sediment ‘seedbanks’.
Charophytes are attractive to waterbirds and provide an important food source as
well as provide habitat for other lifeforms.
Charophytes welcomes papers of high-quality, original
research, including critical reviews and taxonomic notes. The scope includes
ecology, biogeography, physiology, ecophysiology, palaeontology, management,
taxonomy, genetics, molecular biology, phylogeny, morphology, systematics and
evolution, in fact all aspects of research on charophytes in the broad sense.
Papers should engender a broad interest, and
reports that break new ground or advance our understanding of charophytes in
general are particularly welcomed. Reviews of current knowledge are also
welcomed, provided they incorporate an account of implications and/or new
directions for research. Taxonomic notes consisting of corrections of
nomenclature or taxonomy, or descriptions of new species are welcomed. The journal’s home page is http://www.charophytes.com. An ISI Journal Citation Reports Ranking is not yet available.
A recent special issue of the journal Ecological Management and Restoration (Vol 7, Supplement 1, June 2006) is a collection of papers submitted by participants of a workshop held at CSIRO Sustainable Ecosystems in Canberra in August 2005 titled Mapping vegetation condition in the context of biodiversity conservation. The workshop brought together managers and researchers with an interest in vegetation condition policy and assessment at various scales. The aims of the workshop were to: examine conceptual approaches used to define vegetation condition; identify the drivers for information on vegetation condition; provide an overview of methods for assessing vegetation condition at various scales; and demonstrate how information on vegetation condition may improve the management of biodiversity. Papers on these issues are presented in the special issue of EMR. The paper abstracts can be viewed online at by going to http://www.blackwell-synergy.com/loi/emr .

The June issue of the Botanic Gardens Trust
ecological journal Cunninghamia Vol
9(3) is dedicated to publishing the first two papers in the NSW Vegetation
Classification and Assessment project. The first paper discusses vegetation
classification generally and describes the methods, parameters and rules used in
the project including detailed descriptions of the NSWVCA database. The other
paper describes 213 plant communities classified for the 8 western bioregions of
NSW (57% of NSW or 45 million hectares) being the NSW Western Plains. A detailed
audit of the vegetation in all 83 Western Plains protected areas is also
provided. A CD in the pocket of the journal contains a read only version of the
NSWVCA database, full record reports (90 fields of information per community)
for 8 bioregions, two CMAs and all of the NSW Western Plains and a Short Report
(28 fields) of the same. A spreadsheet of a bibliography of vegetation
information for western NSW is also presented on the CD. The project so far has
taken six years of work by John Benson of the Botanic Gardens Trust. The project
is planned to continue eastwards to cover more bioregions and more Catchment
Management Areas. The vegetation units are being incorporated into the CMA PVP
biometic tool and are suitable for environmental planning and assessment at
local, regional and national scales. Contact the Botanic Gardens shop on 02 9231

The Australian Government has just announced $23 million in funding over the next 4 years to develop three world-class multi-disciplinary research hubs which will explore Australia’s most pressing environmental challenges. The funding recipients are the first under the Australian Government’s $100 million Commonwealth Environmental Research Facilities (CERF) Program. The new hubs are:
· Research hub for Applied Environmental Decision Analysis University of Queensland. Professor Hugh Possingham will receive $6.9 million to establish a research hub addressing Australia’s environmental planning, decision making and policy approaches. Prof Possingham will lead 12 principal researchers and up to 60 research fellows and PhD students from VIC, QLD and ACT institutions. The team will develop tools that take account of social as well as environmental implications of management and policy decisions for a range of persistent environmental challenges including feral animal control, managing invasive species in the Australian alps, fire management in urban/rural overlap areas and environmental river flows to improve the management of these challenges.
· Research hub for Tropical Rivers and Coastal Knowledge (TRACK). A group of seven researchers from WA, NT and QLD will receive $8 million to improve management information for northern Australia’s catchments (rivers and coasts between the tip of Cape York Peninsula and Broome). The hub will identify important natural assets and ecosystem services to provide a solid base upon which to assess the social, economic and environmental impacts and the viability of proposed developments in the region. The hub will generate and disseminate the knowledge needed by regional NRM bodies, governments, Indigenous communities and industry to support the sustainable management of tropical rivers and costal environments.
· Research hub for Landscape Logic: Linking Land and Water Management to Resource Condition Targets. University of Tasmania’s Professor Ted Lefroy will receive $7.9 million to establish a research hub that will develop tools to improve the sustainability of natural resource management practices. He will lead a partnership of 24 researchers across seven institutions and six regional catchment management organisations including the North East, Northern Central and Goulburn Broken Catchment Management Agencies in Victoria, and the NRM North, South and Cradle Coast in Tasmania. This hub will develop a practical approach to natural resource management by identifying the links between land management at paddock, farm and forest block level, and landscape health at catchment and regional levels, improving returns from existing and proposed public investments in natural resource management. The model will be unique in its applicability across a broad range of environments, enabling environment managers to identify localities and management activities that are contributing to improving or decreasing the health or sustainability of our landscapes, and where appropriate suggest alternative activities to improve management outcomes. This work will draw on the research that has been undertaken through the Australian Government’s previous investment in natural resource management through the Natural Heritage Trust and the National Action Plan on Salinity and Water Quality. It will contribute to Australia’s management of emerging markets for sustainable use of natural resources such as water, carbon and biodiversity.

DEH are also looking to run further funding rounds under the CERF program later this year, focussing on individual research fellowships and projects. The details of this are yet to be sorted out, so keep an eye on their website for new information http://www.deh.gov.au/programs/cerf/index.html
In June, Federal and NSW state ministers announced $21 million in funding from the National Action Plan for Salinity and Water Quality and the National Heritage Trust for biodiversity projects across NSW. Some of the 49 major environmental projects soon to be underway are: a project aimed at rescuing the endangered Corroboree Frog from extinction; projects targeting salinity; erosion and pollution in the Murray River and its surrounds; research on dryland salinity and monitoring of eight key sites around NSW; monitoring of great white sharks and grey nurse sharks; and habitat management for the Broad-headed snake.

In May 2006, the Australian Government released a
national plan to “protect our precious coastal environment and to safeguard
our coastal industries and communities”. The plan
outlines a nationally cooperative approach to achieving ecologically sustainable
development through integrated coastal zone management (ICZM). The plan can be

The new Cotton Catchment Communities Cooperative Research Centre has been ramping up its biodiversity research for the cotton industry. As the CRC’s name implies, considerable emphasis is now being placed on research and extension activities associated with natural resource management in partnership with CMAs, agencies and industry. Biodiversity and ecosystem services makes up a sub program in the CRC. The CRC is commencing research on riparian zones, native vegetation, birds, beneficial insects, bats, on farms wetland and enhancing water storages, fish on farms and surface and ground water issues. The CRC would like to hear from anyone wanting information or collaborating in a project. For more information www.cotton.crc.org.au or contact Guy Roth on 0417 223 179.
Researchers at western New South Wales-based Charles Sturt University (CSU) have warned that efforts to eradicate European Carp from waterways could leave native birds with little to eat and vulnerable to population declines. Dr Ian Taylor says many of the bird species in the Murray Darling Basin are now reliant on carp as a main food source because native fish have been depleted. He says current policies on removing carp from waterways need to be reviewed before up to 10 species of water birds face severe population declines and that native fish populations need to be boosted first.

to surface waters from mining operations
Letter to the The Editor, Sydney Morning Herald
May 10, 2006
The NSW Government’s water recycling plans are welcome and the need for ongoing water restrictions are understood. However it is ironic that, while citizens are being fined $220 for illegally watering gardens, mining companies are being allowed to crack and contaminate major rivers all around the state. This is causing water losses far greater than that resulting from any number of garden hoses.
For example, in the Macarthur region alone, the Lower Cataract River, once a major tributary of the Nepean, has lost 50% of its flow down cracks and fractures, and is badly polluted. The nearby Georges River is also losing flow down cracks. Worse still, BHP Billiton is seeking approval to mine so close to the Upper Cataract River that further cracking is predicted – and this stretch of the river is a conduit for around 7% of Sydney’s supposedly precious water supply. The company is asking the Sydney Catchment Authority to raise the minimum amount of water now being put down the river from the Cataract Dam from 1.3 million litres per day to 5 million litres per day. The extra amount is to cover probable future water loss down new cracks, and to dilute pollutants leaching from the fractures.
The Bargo River, another major tributary of the Nepean, is also likely to be cracked if plans put forward by Centennial Coal are approved by Minister Ian Macdonald. At present, two local collieries – Tahmoor and Douglas - are pumping an average of 7 tonnes of salt per day into Nepean tributaries, and we wonder why the river is sick!
These examples are from just one area of NSW – as stated above, several other major rivers in NSW are under threat from permanent damage from mine-induced subsidence. Others have been “re-located” to facilitate mining (Goulburn River, Wambo Creek), while at least one has disappeared altogether (Bowmans Creek). Is short term profit from coal really more important than conserving the water in our major rivers and creeks for future generations ?

Central West farmers Ambrose and Lisa Doolan are developing a demonstration reach - a stretch of stream that shows the benefits of restoring aquatic habitat – on their Castlereagh River property,'Toorawandi'. Deep river holes are important refuge areas for native fish in unregulated rivers and creeks, but willow invasion has encouraged silting in an historic deep hole on 'Toorawandi'. The Doolans will poison the willows and remove the silt to restore the hole. As well, a woody structure will be embedded upstream of the deep hole to encourage natural scouring to maintain it. They received funding for the work through the Central West Catchment Management Authority (CMA) and NSW DPI will organise relevant permits and guidelines and help with the design for the structure.

South-western Australia has been identified as a likely hotspot for species extinction in the future due to global warming, in a study released by scientists in Sweden. The study, which has been published in the journal Conservation Biology (vol. 20, issue 2, April 2006), examined 25 biodiversity hotspots and estimated extinction rates in these areas using both species-area and endemic-area relationships. The study predicts that <1 to 43% of the endemic biota (on average 11.6%) species could be driven to extinction if current climate and habitat change projections continue for the next 100 years. Especially vulnerable hotspots were the Cape Floristic Region, Caribbean, Indo-Burma, Mediterranean Basin, Southwest Australia, and Tropical Andes, where plant extinctions per hotspot sometimes exceeded 2000 species.

Aral sea increasing in size
Fresh water is flowing back to the stricken Aral Sea, raising hopes of a return to its former glory days. For decades, waters of the fourth-largest lake in the world were systematically diverted for agriculture and industry by the USSR government. As a result, the Aral Sea shrank to a small percentage of its original volume. Now it is refilling, thanks to $84 million the World Bank has poured into a project to increase the flow of the sea's tributaries. Since 2005, the surface of the northern sea has grown by a third. The influx is great news for wildlife. The North Aral Sea is now considerably less salty, bringing back biodiversity, according to the World Bank's project leader. Source: New Scientist, 8 April 2006

New Zealand announces national
The New Zealand government announced a suite of actions to protect and improve national freshwater resources. The Sustainable Water Programme of Action will develop, for the first time, a strategic and nationally consistent approach to managing New Zealand's freshwater resources. Some of the actions agreed today (April 10 2006) include scoping national policy statements and national environmental standards for freshwater management; and investigating criteria to identify nationally outstanding (or significant) natural water bodies. All actions are based on the continued management of water by regional councils and as a public resource. The Programme will be developed in partnership with local government, sector and interest groups. We will be organising a series of meetings around the country to discuss the future of the programme in the near future. We will contact you with confirmed dates and locations.

Full text of consensus statement published:
Freshwater ecosystems (including inland saline wetlands and mound springs) are
among the more imperilled ecosystems in the world. Australia is no exception,
but their protection has lagged behind programs of terrestrial protection.
Freshwater protected areas are an essential component of biodiversity
conservation programs, but a systematic approach to their development in
Australia has been slow, and hindered by incomplete ecosystem inventories at
State and national levels. We examine this problem and suggest avenues for
action. Further, while there is no shortage of relevant legislation and policy
for protecting inland aquatic ecosystems in Australia, some protective
mechanisms have not yet been used, many years after their development. In some
places ‘protection’ has been only partially applied without regard to
important issues of hydrologic connectivity – with species extinction as a
direct consequence. The most urgent priority is to identify those aquatic
ecosystems most at risk. A comprehensive national assessment of the conservation
status of freshwater ecosystems should be undertaken immediately. Such an
assessment would provide both a platform and an impetus for the systematic
expansion of the nation’s freshwater protected areas. Political will and
community support are then essential for effective conservation, utilising the
plethora of conservation and management tools available.

The NSW Minister for Primary Industries, Ian MacDonald, listed the Aquatic Ecological Community in the Natural Drainage System of the Lowland Catchment of the Lachlan River as an Endangered Ecological Community in Part 3 of Schedule 4 of the Fisheries Management Act 1994 (gazetted 9 December 2005, http://www.gai.dpws.nsw.gov.au/Gazette/Gazette.htm). An interim order has been put in place to allow the continuation of recreational and commercial fishing in the Lachlan endangered ecological community, pending a species impact statement on the activity.
The first major water bird breeding event on the lower Lachlan River in five years has occurred, with a 15,000-strong straw-necked ibis colony along Merrowie Creek, west of Hillston. Other waterbirds have also gathered in the area, including royal spoonbills, pink-eared ducks and the endangered freckled and blue-billed ducks. The breeding event appears to be in response to a replenishment of flow delivered by State Water from an allocation provided to the environment earlier this year following good catchment rains. An abundance of food such as caterpillars and locusts resulting from good local spring rains may have also been an important trigger.

Deep in the Barmah forest (along the Murray River between Echuca and Tocumwal) there's a breeding frenzy going on, the likes of which have not been seen for five years. Biodiversity in the forest appears to be reveling following a massive release of water that the NSW and VIC governments have been saving up for five years in dams. Beginning with the first release in October 2005, the two state governments plan to release 500 billion litres into the forest, sustaining a five-month-long flood. The Age newspaper reported in late November 2005 that stands of old red gums were soaking in a metre of water and that the wetland was alive and teeming with lush growth, birds, frogs, huge dragonflies, black snakes, turtles and fish and the great egret was breeding on the Victorian side of the Barmah for the first time in 30 years. The flooding represents the biggest environmental flow in Australia's history. (http://www.theage.com.au/news/national/a-little-water-fuels-a-frenzy/2005/11/25/1132703376877.html).

Macro Water Sharing Plans are currently being presented by the Department of Natural Resources for catchments around the state. The latest Macro Water Plans aim to protect the health of the state's unregulated rivers and follow on from water sharing plans already in place for the regulated rivers. A recent meeting at Coffs Harbour, revealed that the first priority with the Plans is to maintain acceptable environmental flows, acknowledgement of basic landholder rights to draw on water for domestic use and stock watering, then town water supply and finally along the priority line, water for irrigation purposes. Part of the Macro Water Sharing Plans include the ability to trade water under certain circumstances in the unregulated rivers and streams.

In the far south west of NSW, where the Murray River meets the Murrumbidgee, there's growing concern about the health of the regions wetlands. The Junction Farmers Group, claims the wetlands on the lower reaches of the Murrumbidgee, below Balranald, are in desperate need of a drink. The country at the junction of the Murray and Murrumbidgee is home to river redgums, lignum forest, and reed beds. It's also one of the eastern most nesting sites of the endangered Regent Parrot. But landholders say it's more than ten years since there's been a big enough flush in both rivers at the same time, to overflow the banks and fill the wetlands. Lance Howley from the Junction Farmers Group says the environment is suffering because of poor water management. He says a potential flooding event last year didn't happen because upstream irrigators were allowed to pump off allocation or supplementary water. The Department of Natural Resources says access to supplementary water is enshrined in water sharing plans. But the Department's David Harriss says the impact of supplementary flows on the downstream environment is being considered as part of a review of the NSW water sharing plans. That review is due to report mid next year. (Source: ABC Rural news online Tuesday, 17/01/2006)
A new report has compiled historical evidence of native fish in the Murray-Darling Basin at the time of European settlement — from the diaries of the first explorers.

Planting trees willy-nilly to counter increased carbon dioxide concentrations in the atmosphere may actually result in other environmental damage. An international team publishing in Science argues that while tree plantations can be an effective tool for slowing CO2 concentrations, the wrong plantings in the wrong area at the wrong time can suck streams dry and turn fresh water salty. "We wanted to determine the trade-offs of trying to solve one environmental problem by manipulating another part of the landscape," says Australian contributor Dr Damian Barrett, principal research scientist with CSIRO Land and Water in Canberra.

As the Earth warms, many species are likely to disappear, often because of changing disease dynamics. Here we show that a recent mass extinction associated with pathogen outbreaks is tied to global warming. Seventeen years ago, in the mountains of Costa Rica, the Monteverde harlequin frog (Atelopus sp.) vanished along with the golden toad (Bufo periglenes). An estimated 67% of the 110 or so species of Atelopus, which are endemic to the American tropics, have met the same fate, and a pathogenic chytrid fungus (Batrachochytrium dendrobatidis) is implicated. Analysing the timing of losses in relation to changes in sea surface and air temperatures, we conclude with 'very high confidence' (> 99%, following the Intergovernmental Panel on Climate Change, IPCC) that large-scale warming is a key factor in the disappearances. We propose that temperatures at many highland localities are shifting towards the growth optimum of Batrachochytrium, thus encouraging outbreaks. With climate change promoting infectious disease and eroding biodiversity, the urgency of reducing greenhouse-gas concentrations is now undeniable.

Listing of wild rivers in New South Wales
In November 2005 the Minister for then Environment issued a media release which I have attached in full below. Immediately after this attachment is a second release made on Dec 8 by the DEC about the wild rivers. The wild rivers were declared in the Government Gazette on the 2 December 2005, page 9911, or page 5 of part 2 of the Pdf version in the link below:
The Washpool Creek sub-catchment falls within Washpool National Park. Washpool National Park and the adjacent Gibraltar Range National Park form part of the World Heritage listed Central Eastern Rainforest Reserves of Australia (CERRA). The remote and rugged landscape has limited European disturbance to cedar cutting, localised patches of logging and bush grazing and the entire sub-catchment is wilderness.
Forbes and Upper Hastings sub-catchments occur within Werrikimbe National Park and form part of the Central Eastern Rainforest Reserves of Australia (CERRA) World Heritage area.
The Kowmung River and catchment have attracted passionate interest from bushwalkers and nature lovers for over 100 years but have also been the site of natural resource use and of major mining and forestry proposals. Most of the catchment was protected by establishing Kanangra-Boyd National Park.
The Brogo sub-catchment is located in the Bega catchment in south east NSW. The highly fertile Bega Valley has undergone substantial land clearing and the rugged and mountainous upper reaches of the catchment provide important examples of the catchment's original features and freshwater fauna and flora. The Brogo sub-catchment is immediately upstream of the Brogo Dam and provides water for the Bega district's town and irrigators.
“Ecosystems & Human Well-being: Wetlands
& Water Synthesis” launched at Ramsar COP9T
Tuesday, November 08, 2005 | Kampala, UGANDA
Secretary General, Ramsar Convention on Wetlands, Peter Bridgewater, launched the fifth synthesis report by the Millennium Ecosystem Assessment (MA), “Ecosystems & Human Well-being: Wetlands & Water Synthesis” during the opening ceremony of COP9. The Wetlands and Water synthesis was designed for the Ramsar Convention to meet the need for information about the consequences of ecosystem change for human well-being and sought to strengthen the link between scientific knowledge and decision-making for the conservation and wise use of wetlands.
Highlighting the findings from the report, Bridgewater, who was also a member of the MA Board, noted that, “The degradation and loss of wetlands is more rapid than that of other ecosystems. Similarly, the status of both freshwater and coastal wetland species is deteriorating faster than those of other ecosystems.”
He also stressed the need to balance the desire to add more sites to the Ramsar List of Wetlands of International Importance with ensuring their effective management and representativeness. He called for: synergies among biodiversity-related Conventions; better environmental governance frameworks; and capacity building.
In a special presentation on the Wetlands and Water synthesis during a COP9 Plenary session, Synthesis Team Co-Chair, Rebecca D’Cruz, stressed that ecosystem services are vital to human well-being, lamenting that many of these services are overused, mismanaged or degraded, and highlighted policy choices available to reduce wetland degradation while maintaining benefits.
Commenting on the accelerated wetland degradation, she highlighted a reduction of human well-being, especially in developing countries, coupled with an increased demand for wetland services. She said policy decisions must address trade-offs between current and future use, and emphasized cross sectoral and ecosystem approaches. Finally, she noted that the report would help set the future agenda for Ramsar, and could be used to raise awareness on wetlands.Read more
CSIRO publication: managing change in water-related structural adjustment
According to a report published in September 2005: "If
adjustment is impeded, the most significant adverse impacts are often on the
capacity of the most talented in a district or an industry to innovate.
Australian history is rich with stories of the adverse effects of attempting to
shore up existing businesses experiencing financial difficulties rather than
allowing others the opportunity to enter and existing businesses to adjust and
expand. There are many opportunities for governments to facilitate and expedite
The future of
Given the capital gains tax implications of buying and selling water and the report’s focus on ways to expedite adjustment, the report identifies an opportunity to use either voluntary buyback and/or compulsory acquisition as a means to increase the quantity of water available to enhance environmental flows."

threatening process: mining subsidence
The NSW Scientific committee has made the following final determinations from 9 June 2005 to 30 September 2005.
· Alteration of habitat following subsidence due to longwall mining. The main impact of underground coal mining (which occurs in the northern, southern and western coalseams of NSW) is subsidence, associated cracking of valley floors and creeklines and effects on surface and groundwater hydrology and dependent ecosystems.

Over the next decade Catchment Management
Authorities (CMAs) in NSW will put hundreds of millions of dollars into natural
resource management activities on private and public land. These funds have the
potential to make a major contribution to the protection and restoration of
biodiversity. One of the biggest challenges facing CMAs is ensuring that the
types of activities funded have real benefits for long-term biodiversity
conservation and are undertaken in places where they are most needed.
CMAs throughout the state are formulating
priorities for investment that will influence how money is spent on the ground.
These priorities will be expressed through individual Catchment Management Plans
(CAPs) to be finalised by the end of 2005. CMAs need the resources and skills of
government agencies involved in NRM and support of the community to operate
effectively. The NSW Department of Environment and Conservation is providing
support through the provision of a DEC staff member to each CMA throughout the
state. In some areas joint projects are being developed to help identify
priorities for investment in biodiversity conservation.
There will be opportunities to comment on CAPs when
they go on public exhibition at the end of the year. There are also
opportunities to obtain funding through CMA for projects that have on-ground
biodiversity benefits and help CAP targets. For more information about your
local CMA see http://www.cma.nsw.gov.au/
NSW Dept of Environment and Conservation has
recently consulted on an overview paper for biodiversity certification and
biodiversity banking in coastal areas. The proposal seeks to correct market
failure by recognising biodiversity values, and create new opportunities for
private sector conservation management of land to complement the State's
national parks and other protected areas. A second paper - BioBanking: A Biodiversity Offsets and Banking Scheme (Working
Paper) - will be published shortly. The purpose of the paper is two-fold.
Firstly, to form the basis of discussions with key stakeholders in order to
develop the detail of the scheme further. Secondly, to invite comments or
suggestions on the paper from other interested stakeholders. The paper will be
published, along with all other documentation on BioBanking at http://www.environment.nsw.gov.au/resources/biodiversitybankingweb.pdf
in November. Consultation will close on 31st January 2006.
The wetlands of Nocoleche Nature Reserve and Paroo-Darling National Park on the Paroo River in NSW are being considered for nomination to the Ramsar Convention. The Baakandji and Budjiti people whose country includes the Paroo River in NSW are working with NSW DEC to progress the nomination. A cultural mapping project has been carried out assist the broader community understand the traditional and contemporary values the Baakandji and Budjiti people have for the Paroo River. The project will be presented as a case study on the Aboriginal values by the Budjiti representatives to the Convention of Parties meeting in Uganda in November 2005. It will contribute to the debate on how the Convention can better incorporate indigenous cultural values. It has been funded by National NAP/NHT, Aboriginal Heritage Program, Policy and Science and Parks and Wildlife Co-management.
Land recently purchased in the Riverina region is set to become the newest addition to the national parks system. Yanga, an 80,000 hectare property located on the Stuart Highway between Sydney and Adelaide, was home to the largest privately owned Red River Gum forest in Australia. Originally purchased in the 1830s, the property has extensive Murrumbidgee River frontage and is rich in natural, European and Aboriginal cultural heritage. DEC was invited to consider purchasing the property from the Black Family who have owned the property for about 80 years. The Black family have always recognised the unique natural and cultural heritage values of the property. They had even employed a Heritage Coordinator to identify early European and Aboriginal sites on the property to help avoid any accidental disturbance through station or other activities. The park is expected to inject some $8 million into the local economy and employ up to eight local staff within the first 18 months, with a further 100 jobs created indirectly in the long term. Yanga will join the nearby World Heritage listed Mungo National Park.
Money raised by recreational fishing licences has been placed into special trusts to improve recreational fishing in NSW. This year $360,000 has been allocated for the Fish Habitat Grant Program to encourage the community to undertake fish habitat rehabilitation projects. Expressions of interest are sought from individuals, clubs, groups or local councils interested in rehabilitating fish habitats in freshwater and saltwater areas of NSW. Grants of up to $30,000 are available where matched on a dollar-for-dollar basis (cash and/or in-kind support).

The Fisheries Aquatic Ecosystems Research section of NSW Dept Primary Industries is currently involved in research to control carp in the Murray-Darling Basin. One project is identifying the Basin's carp spawning hotspots and examining the relationship between those hotspots and subsequent recruitment of carp. A second project, to start in 2006/07, will set up a demonstration site in the Barmah-Millewa Forest to investigate ways of regulating water height and flow to discourage carp spawning.

The QLD parliament has recently passed the Wild Rivers Act 2005 (proclamation 14 October 2005), with the purpose not to identify or designate any wild rivers but to set up a framework for declaring rivers to be wild. In this respect the Act is unlike the only other piece of similar Australian legislation - Victoria's Heritage Rivers Act 1992 which incorporated listing of 18 rivers. Once declared, wild rivers in QLD are to be given a level of protection which is less than a national park but greater than that achieved by applying principles of ecologically sustainable development. The original policy identified 19 potential wild rivers, however conservationists have called for 60 rivers throughout QLD to be considered. At present, a declaration for the Statten River is under preparation, and presumably others will follow. The process of declaring a wild river involves an initial nomination by the Minister (members of the public are not entitled to make nominations), a public consultation process followed by formal declaration. Once declared, a wild river area will be divided into two units - ‘high preservation area’ (a 1km buffer around the river and major tributaries and wetlands or other significant features such as gorge country associated with the river) and the ‘preservation area’ (the remaining part of the nominated area). Prohibition of activities will be most stringent in the high preservation area and will include restrictions on vegetation clearing, agriculture and mining, and water extraction (to be limited to 1% of median annual flow).

Cane toads (Bufo marinus) are using roads to spread through Australia's tropical north and are moving at rates faster than previously thought. Rick Shine and co-workers from the University of Sydney's School of Biological Sciences radio-tracked the toads when they arrived at Fogg Dam near Darwin, in January 2005. The toad front is also moving in the order of 70 km per year, much faster than the 10-20 km previously thought. The researchers observed that the toads prefer to avoid travelling through vegetation and breed in shallow water with a gently sloping edge, surrounded by open ground. They suggest that toad control should focus on leaving roadside vegetation intact to reduce their movement. Read more at http://www.abc.gov.au/science/news/stories/s1460974.htm.

UNESCO has accepted the Barkindji Biosphere Reserve in NSW as part of the World Network of Biosphere Reserves. The reserve is Australia's thirteenth biosphere reserve, covering more than 26,000 hectares of floodplains, wetland and open plain country along the Murray River around Wentworth in south western NSW. A biosphere reserve includes one or more protected areas and surrounding lands that are managed to combine both conservation and sustainable use of natural resources. Other NSW biosphere reserves are Kosciuszko National Park and Yathong National Park. There are four biosphere reserves in Victoria, 2 each in SA and WA, and 1 each in Tasmania and NT.

In February 2005, NSW Fisheries launched a detailed draft recovery plan for one of the State’s most popular recreational angling fish – the silver perch – which once occurred in large numbers in the Murray-Darling region. Decades of overfishing has taken a toll on silver perch populations, which have been listed as vulnerable since 2000. The recovery plan aims to enhance the few isolated populations left and return wild stocks to a sustainable level, which would be a boost for recreational angling and tourism in rural and regional NSW. Submissions on the silver perch recovery plan are now closed, however it can be viewed online at http://www.fisheries.nsw.gov.au/__data/assets/pdf_file/22763/Silver_Perch_Draft_Recovery_Plan.pdf
The Recreational Fishing Freshwater trust has set aside $300,000 over three years to rehabilitate freshwater fish habitats, with an initial $110,000 to fund 14 small projects at a range of popular fishing spots, including around Brewarrina, Condobolin, Wagga Wagga, the Hawkesbury and the Parramatta River. The funds, which come from licence fees from recreational anglers, will be used to help restore floodplain and freshwater wetlands, enhance fish passage (including building fish ramps and ladders), re-snagging, and weed removal and restoring vegetation. A table showing the range of projects can be viewed at: http://www.fisheries.nsw.gov.au/general/news/Newsroom/news_archives_2005/22_feb_05_-_fish_habitat_work_continues_across_nswIn an Australian first, scientists from the NSW Department of Primary Industries are using a high-resolution underwater sonar camera to measure fish migrations in the state’s rivers. The technology, which works without interrupting the natural behaviour of fish, was developed in the mid-1990s by the US Navy for divers to survey mines attached to the hull of ships, but this is the first time underwater sonar cameras will be used in Australia for scientific research. So far, the unit has allowed the remote observation of fish in areas where scientists have had difficulty observing them in the past, particularly in muddy or dirty waters or at night. It is common knowledge that dams, weirs and floodgates block fish migrations. The technology allows scientists to see how fish react when they are confronted with such barriers and the information may then be used for better management of freshwater fish populations.

As part of the NSW government’s Level 3 water
restrictions for Sydney, the Illawarra and Blue Mountains (effective from 1 June
2005) environmental flows released to the Hawkesbury-Nepean River will be
decreased by about half. Some fear this reduced flow may lead to increased
nutrient and contaminant levels and thus contribute to environmental problems

A stocktake of wetlands in the Murrumbidgee
Irrigation Area (MIA) has recently been completed and the results compiled in a
colourful new report, An Inventory Of
Wetlands In The Eastern MIA (Harrison and Roberts 2005). The inventory is a
compilation of existing knowledge on the wetland resources in the eastern MIA.
Principal sources of information included existing reports and publications, and
the local and regional knowledge of individuals.
For almost 40 wetlands identified in the study
area, information has been compiled on the following themes: biophysical
attributes; ecological and cultural values; ecological condition; threats;
management activities and plans; and a reference list.
An aerial photograph also illustrates each wetland.
Copies of the Inventory have been placed in local
and regional libraries and with other relevant organisations. Additional copies
are available for $25 and further information is available from Louise Harrison

least 450 flowering plants and 400 invertebrate fauna species are at risk of
extinction as a direct result of salinity in Western Australia’s agricultural
zone, according to the findings of a recent survey by the Department of
Conservation and Land Management (CALM), the WA Museum, the University of
Western Australia and the University of Adelaide. In addition to species
extinctions, all remaining remnants of many valley-floor wetland, shrubland and
woodland communities could disappear because of salinisation. (The survey also
found 25 new invertebrate species and 6 new plant species revealing the lack of
knowledge about the region’s biodiversity in general.) The survey was part of
an ongoing program to document the WA’s biodiversity and conservation status.
A summary of the survey will be released by CALM in the next few months.
findings will be relevant to the monitoring and predicting of salinity impacts
on biodiversity in eastern Australia.
A recent tri-state report released by the Murray Darling Basin Commission (MDBC) revealed that the number of dead and dying River Red Gums has increased from 51 percent in 2002 to 75 percent in 2004. Surveys of tree health were conducted at 155 sites along a 1450 km stretch of the Murray River from the Gunbower-Koondrook-Pericoota State Forests to Mannum in South Australia. Water extractions, reduced flow and lack of periodic flooding combined with recent drought conditions are thought to be the main causes of Red Gum forest decline. However, there is also continuing pressure on the forests from logging. Read the MDBC report online at http://www.mdbc.gov.au.

Within the CSIRO Water for a Healthy Country Flagship, we are assessing how water management regimes influence the distribution of vegetation and their associated faunal communities in the Murray Darling Basin. To do this we are compiling distribution data from the CSIRO National Collections of plants, invertebrates and vertebrates with data from various ecological survey datasets, and the data from Australia’s Virtual Herbarium, and other institutions. This will be an extremely rich mega-dataset, with approximately 400,000 distribution points for over 5,500 species found in the Basin, by far the biggest dataset assembled for this purpose. To assess the power of the data in influencing water management decision-making, we will be conducting a number of tests of the dataset. For example, we will be investigating the extent to which the dataset samples the range of environments found in the basin, at the different scales of river corridor, floodplain, and basin-wide. We will also assess the usefulness of the data for predictive modelling at each scale of investigation The data provides an opportunity to evaluate the contribution of the Living Murray icon sites to conservation of biodiversity in the Basin. We will also use the biological data in conjunction with comprehensive flood histories to predict the responses of vegetation communities and other biota to changes in water management.
A large part of the Innamincka Station around Coongie Lakes in South Australia's far north-east is to be turned into national park under a cooperative agreement between conservation and industry groups in SA. The 300 square kilometre area, which has been part of the cattle station for the past 101 years, includes five freshwater lakes as well as sand dune country. The petroleum industry also has a considerable interest in the area. Despite these multiple interests, the area will be dedicated as a national park following many years of campaigning and negotiation. Increased understanding between the groups has led to an historic agreement between the station owner (S Kidman and Company who has opted to voluntarily relinquish the land) the SA government, pastoralists and the petroleum industry.

A recent crisis meeting in Barooga of scientists and decision-makers from throughout the Murray-Darling Basin has highlighted the severity of arrowhead (Sagittaria graminea Michx) infestations in the waterways of the region. The weed was first identified in 1962 near Katandra West and Wunghnu. Major spread began in the 1980s and now it is choking many waterways and wetlands in the Murray Valley, Broken Creek and Murray River. With prolific seed production and an extensive underwater network of rhizomes, roots, corms and submerged rosettes, the plant has now gained a strangle-hold on waterways in northern Victoria.

Researchers from the the Murray Darling Freshwater Research Centre say they are keen to reintroduce murray crayfish to Mallee stretches of the Murray River to see if the world's second largest crayfish can still survive in the area. A six-month study last year covered 700 kilometres of the river from Nyah to the South Australian border, but captured only 74 murray crayfish. Reasonable populations were found around Swan Hill, Nyah and generally upstream around Wakool Junction. However, downstream of Wakool Junction very few were caught and none were found below Mildura. Future research aims to reintroduce crays fitted with radio transmitters to monitor their progress and gather data about their movements. Source: ABC News Online 7 June 2005.

As cane toads continue to move across the Top End of Australia there are fears that they will reach the north of Western Australia. Scientists predict that they'll be across to the Kununurra wetlands within one or two wet seasons. The WA Government will spend $900,000 on trapping, surveillance and advertising campaigns across the state to attempt to stop the toads’ progress. Source: ABC News Online 4 June 2005.
In the NT, a $40,000 Envirofund grant has been provided to the conservation group ‘Frogwatch North’ to help install cane toad traps at key wetland sites near Darwin, Palmerston and Bachelor. The project, with the help of community groups aims to limit the spread of the toad.
Back in QLD, the Pest
Animal Control CRC has welcomed $1 million worth of funding from the Queensland
Government to develop a lethal control agent for the Cane Toad. This funding will enable researchers to search for a Cane Toad-specific
toxin, which is currently the ‘strategic gap’ in Cane Toad control, for use
in baiting and trapping programs.
The Commonwealth Department of Environment and
Heritage has recently added “the biological effects, including lethal toxic
ingestion, caused by Cane Toads (Bufo

A controversial approach to water management on farms, initiated by farmer Peter Andrews, was featured recently on ABC television’s Australian Story. His approach aims to restore the original contours of eroded drainage lines using woody debris and soil, and to ultimately slow water flow and retain moisture in the landscape. Pioneer plants, including weeds are allowed to grow, stabilise the soil, contribute organic matter and improve conditions for the establishment of more desirable plants such as fodder species and native trees. Whilst this practical approach is primarily aimed at restoring agricultural productivity in degraded areas, there may also be ecological benefits. Improvements in ecological health were reported in terms of improved water quality (e.g. clarity) and an increased presence of native fish. To date this intuitive approach to land restoration has been based on the personal experience of one man, although there are now calls for scientists to become involved in monitoring sites and setting up model farms in other areas.

Much of the marshland had been drained for wheat or dammed for irrigation and the soil became affected by salinity. However, researchers who moved into the marshes and began working with Iraqi scientists after US and British forces toppled Saddam say that the remaining marshland show surprising resilience with high water quality.

Themes on the website include activities and workshops, the Ramsar convention, education, wetland ecology and links to other groups and sources of information.
A one-year project highlighted on the website is The NSW Ramsar Wetlands Communications Program (NSW RWCP), an Natural Heritage Trust funded initiative of the NSW Ramsar Managers Network (coordinated by the Department of Environment and Conservation, Dubbo). This Network identified that there was a need to increase the awareness, appreciation and value of the Ramsar Convention as a key tool for the conservation and wise use of wetlands among government and the broader community. This communications program began on 1 st July 2004 to address this need and has been funded for one year.

The Tasmanian State Government has been accused of hypocrisy over the newly-released draft recovery plan for the giant freshwater lobster. The plan has reignited debate over how close to streams logging should be allowed. Conservationists say the plan won't stop sediments from upstream damaging lobster habitats. But the manager of resource management and conservation at DPIWE, John Whittington, says the plan strikes a good balance between protecting the lobster and the needs of forestry.
The department is calling for public comment on the plan. Copies are available from the DPIWE website, or by phoning the department. You have until the 27th of June 2005 to give them your feedback.

The Nature Conservation Council has lost its challenge to the Gwydir Regulated River Plan. The NCC argued in the Land and Environment Court that the Gwydir Plan was invalid because it failed to give priority to the environment in terms of water allocations. The Court found that the Plan was generally consistent with water management principles in the Water Management Act and provides for water sharing generally in accordance with the Water Management Act and established rules. This decision was made notwithstanding the finding that the Minister for Natural Resources had failed to satisfy the statutory requirement to set aside water for environmental health prior to allocating water for irrigation and other consumptive purposes. The Nature Conservation Council of NSW is calling for the Minister for Natural Resources to immediately review all the water sharing plans across the state.

The Federal Court of Australia has imposed a $450 000 penalty on NSW farmer Ronald Greentree and his company for contravening the EPBC Act by clearing, ploughing and wheat-cropping the Windella Ramsar site. The 100 hectares site is one of four areas collectively known as the Ramsar Gwydir Wetlands, designated under the Ramsar Convention in June 1999. The Ramsar Gwydir Wetlands cover 823 hectares in north-west New South Wales, about 80 kilometres west of Moree. For more information on the Federal Court decision go to http://www.austlii.edu.au/au/cases/cth/federal_ct/2004/1317.html.
James Cook University has received Natural Heritage Trust funding to research the deadly amphibian chytrid fungus, which is found in 45 native frog species. It is not yet known exactly how the fungus kills the frogs but it may release toxins that are absorbed through the skin, or - given that frogs drink and breathe through their skins - it may directly affect water uptake and respiration.

Trials of new fishways in the lower reaches of the Murray appear to be a success, with 12 fish species and more than 4,000 individuals using the fishways in four weeks over January. With most native species reduced to 10 per cent of their pre-European populations, the million dollar fishways are designed to help fish reach previously cut-off upstream breeding grounds. Dr Qifeng Ye from the South Australian Research and Development Institute, says January trials have indicated more than 30 species and a million fish a year will use the fishways.
