Campagne red Neoceratodus

knuffelsessie met australische longvisDe australische longvis (Neoceratodus forsteri) gaat eraan. Op 5 juli jl. gaf de lokale overheid van Queensland toestemming voor de bouw van een stuwdam in de Mary River ten noorden van Brisbane: het laatste ongestoorde leefgebied van de australische longvis (ABC). Deze unieke vis plant zich voort in ondiepe delen van de rivier tussen rijk begroeide onderwatervegetatie. Na de bouw van de dam zullen deze plekken verdwijnen en daarmee ook de laatste in het wild levende exemplaren van deze vissoort.

Al ruim 150 miljoen jaar is het ontwerp van de australische longvis ongewijzigd en omdat het de meest tetrapod-achtige onder de levende vissoorten is bevat de australische longvis waardevole informatie over de evolutie. De australische longvis draagt het verhaal van hoe vissen destijds aan land kropen met zich mee. We’ll be left with nothing but bones and tissue samples and few relics in aquaria. Those sure are beautiful, informative bones…but we can learn so much more from the living animal (Pharyngula Scienceblog). Wetenschappers zijn een actie begonnen om australische politici ervan te overtuigen om van de bouw van de stuwdam af te zien. “We will look so bad in the international scientific community if we go ahead with this dam and wipe them out” aldus professor Jean Joss longvis expert aan de Macquarie University in Sydney. U kunt zelf ook emails sturen aan de senatoren in Australië, alhier.

    ”het verhaal van hoe vissen destijds aan land kropen”. Hmmm,….jammer dat ze nu uitsterven. Maakt e.e.a. eenvoudiger als je ze wilt barbecuen.

    Als ze uitsterven kunnen ze niet aan land kruipen he? Bovendien als ze aan land kropen, waarom zitten ze dan nu nog in het water? Volgens de evolutie zouden ze er toch uit moeten kruipen als die dam er komt? Zie je wel die evolutietheorie is echt maar theorie!

    pfff

    De eerste keer dat een groep senatoren tegen ditsoort plannen zal stemmen, omdat ze een ecosysteem voor willen laten gaan op economisch gewin koop ik een biertje voor ze.

    Carlos: ”een wolf in design schapenpak”? en: ”een ID- adept”? Pffff,…elke dag weer nieuwe verrassingen hiero!,…’tis zo langzamerhand niet meer te doen!!

    @YP,

    Ik meen het niet echt hoor, ik zit Carlos gewoon een beetje te jennen. Maar hij hapt niet zo snel, een door de wol geverfde weblogger ben ik bang, geen eer meer aan te behalen.

    Tuurlijk MP,…ikke begrijp,…soms wat rammelen op het toetsenbord,…losse gedachten en zo,…houdt lichaam en geest rein zullen we maar zeggen!

    @YP,

    Nou losse gedachten:) Ben al maanden bezig haha:) Als je met rein bedoelt scherp dan ben ik het van harte met je eens!

    Precies MP!,..het leven is één grote tombola.

    @YP
    Ben je ook zo gek op sambal? Ik wel:)

    Om maar weer even on-topic te gaan voordat ik een IP-ban van Carlos krijg: Wanneer we de Neoceratodus niet meer hebben dan kunnen we nog onderzoek doen aan de Coelacanth

    Ik heb, zoals het een brave burger betaamt, een mailtje gestuurd, en het volgende antwoord wil ik jullie niet onthouden.

    “The Honourable Henry Palaszczuk MP, Minister for Natural Resources, Mines and Water has asked me to reply to your email of 17 July 2006 concerning the Mary River dam and Australian lungfish.

    The recent extended drought in eastern Australia is the worst for over 100 years. Compounding the problem of shrinking water supply in South East Queensland (SEQ) is the fact this region is one of the fastest growing in Australia with the population expected to grow by over one million people in the next 20 years and a further million by the middle of the century. Water can no longer be supplied and managed on a local basis so work is under way to develop whole-of-region solutions to the future water needs of SEQ. Managing urban water infrastructure is a very complex issue and over the last decade society has placed increased value on environmental outcomes for water infrastructure.

    Future water planning requires the assessment of the magnitude of gains through demand management so that new water supply arrangements to meet any shortfalls can be implemented as the need arises. The South East Queensland Regional Water Supply Strategy (SEQRWSS) involves an assessment of a range of options to increase supply and reduce demand, including:

    · managing demand (for example, targets for reducing consumption, water-sensitive urban design, rainwater tanks, targets for recycling);

    · managing wastage (for example, reducing mains pressure and fixing leaks);

    · additional storage infrastructure (new storages and/or raising existing storages);

    · desalination;

    · potential groundwater sources; and

    · water recycling for urban, industrial and rural purposes.

    Across the region current residential water use averages almost 300 litres of water per person per day.

    The South East Queensland Regional Plan has set targets for significant reductions in residential reticulated potable water use of:

    · 270 litres per person per day by 2010;

    · 250 litres per person per day by 2015; and

    · 230 litres per person per day by 2020.

    However even if these targets are met, a growing population means that demand will still need to be met by supply from new dams. New dams therefore are essential to securing the future water needs for the State’s south-east. The SEQRWSS has been investigating numerous bulk water supply options for the region. Upgrading and implementing new dams is part of the long term vision to the region’s water supply. Determining an appropriate dam site is dependent on local topography, catchment area and runoff leading to the available yield. To support the demands of a growing population and associated industries there is a need to supply large quantities of reliable water.

    The Traveston Crossing Dam site has been identified as the only site in the region where a large capacity dam could be constructed. In the Mary Valley, at least four extra storages would need to be built to provide up to a similar annual quantity of water as the Traveston Crossing proposal.

    Traveston Crossing is SEQs largest undeveloped dam site. It is proposed to build the Mary River project in three phases to progressively meet demand and to reduce immediate landholder and road relocation impacts:

    · Phase 1-2011 Traveston Crossing Dam built with an operating capacity of 180,000 megalitres (ML) and a yield of 70,000 ML per annum;

    · Phase 2-2025 raising of Borumba Dam by about 30 metres to a 350,000 ML capacity to deliver an extra 40,000 ML per annum; and

    · Phase 3-2035 full operation of Traveston Crossing Dam with a total system yield of 150,000 ML per annum.

    The three phase process will more than halve the land area required for the dam from 7,600 hectares down to 2,900 hectares and will reduce the estimated number of properties that need to be acquired from approximately 1,000 down to less than 500 by 2011. This three phase process would ensure yield targets required to meet the water needs of population growth in south east Queensland by 2050 are met.

    A range of detailed investigations on the Wyaralong and Traveston Dam sites are currently underway to confirm the preliminary information. Although the dams, if they proceed, would create significant economic and social benefits for the SEQ region, it is well recognised that they also affect people living in the area, the local economy and environment. Therefore, the decision to build major storage infrastructure is not taken lightly, and substantial resources are put in place to mitigate adverse impacts as much as possible.

    Assessments conducted by the Technical Advisory Panel which advised on the draft Mary River Water Resource Plan concluded that while there may be major impacts close to the dam, substantial recovery is expected further downstream, with limited change in the estuarine and receiving waters, including those associated with the RAMSAR Wetland and the Great Sandy Strait.

    Preliminary assessment has indicated that three endangered species exist in the area that will be affected by the dam. These include the Mary River Cod, the Mary River Turtle and the Lungfish. Mitigation strategies such as fish passage devices will be the subject of detailed environmental impact studies as they were for the Burnett River Dam, where lungfish, for example, have thrived.

    For your information a summary of the key points of an Environmental Assessment of the dam options for the Logan and Mary Basins can be found in Water for South East Queensland- A long term solution available on the Department of Natural Resources, Mines and Water’s website at http://www.nrm.qld.gov.au/water/new_infrastructure.html.

    If you require any further information regarding this matter, please do not hesitate to contact Mr Scott Smith of the Department on telephone 3406 2510.

    Yours sincerely
