Rising atmospheric CO2 concentrations may lead to hard coral extinction in 100 years

Posted by waterweek on 17 October 2007

Berkelmans and Company may be wrong, reported The Sydney Morning Herald (13/10/2007). Corals may dissolve: Bleaching may not knock off the reef. It may just dissolve first.

April 2008 Murray system disaster forecast; tree deaths, massive fish deaths, as water falls below the intake-pipes

Posted by waterweek on 21 September 2007

Water-levels below Lock 1 were projected to fall from their current level of 0.25m Australian Height Datum (AHD), to negative 0.6m AHD in April 2008. Under these projected conditions, massive fish death in the Lower Lakes is more likely. For the worst case scenario, water levels will continue to fall, reaching negative 1.5m AHD in the latter half of 2008. Salinity would rise and make what small irrigation water which was available, poisonous to crops and trees.

Studies in WA-279-P for Blacktip devt find diverse and abundant marine life fauna, Drillsearch report shows

Posted by waterweek on 20 September 2007

There was limited information available concerning the benthic communities in the permit area; however, a previous study by Bowman Bishaw Gorham (unpublished data for Blacktip Project) encountered sandy substrates containing shell and crustacean fragments, and pebbles of terrestrial origin, according to the Drillsearch Energy Limited, Drilling of Marina-1 Exploration Well EPBC Referral Submission (24/7/2007).

Victoria Seed Bank project an “insurance policy” against Australian plant extinctions

Posted by waterweek on 14 September 2007

The Victorian seed bank project is run by the botanic gardens, with help from the Department of Sustainability and Environment.” It was the world’s “insurance policy” against plant extinctions – green thumbs from across the globe banking tens of thousands of seeds for the future, reported The Age (7/9/2007, p. 4).

280 species so far: Called the Millenium Seed Bank, the project was started by Britain’s Royal Botanic Garden in Kew, and 18,000 plant species had already been catalogued and stored, The Age reported. The Victorian arm of the international effort – the Victorian Conservation Seedbank – started two years ago, and scientists had so far collected 4.5 million seeds for the cause, representing 280 species. After the seeds were dried and cleaned, they were stored in freezers set at minus 20 degrees. The idea was that if a plant died out, the banked specimens could be used to reintroduce it to the wild. Half of the collected samples would be deposited with the UK bank, with the rest to be stored at Victoria’s National Herbarium at the Royal Botanic Gardens at Melbourne.

“Extinct” plant found: The Age reported: “More than 3000 native species of plants can be found in Victoria, but about 700 are considered to be under threat of extinction. Collection of Victorian seeds started in October 2005. Items banked so far include seeds from a daisy bush that grows on a single limestone marble outcrop in East Gippsland, and seeds from a eucalypt known from just one plant in the Wimmera. The collection work has also led to the rediscovery of Pimelea spinescens, a plant thought to be extinct since 1901.
