THE key recommendation in the Native Fish Strategy for the Murray Darling Basin 2003-2013 – a document developed by the Murray Darling Basin Commission, (MDBC) and adopted by the Murray Darling Basin Authority (MDBA) – was the need to address the issue of cold water pollution in particular from the Hume dam. The strategy, published [...]

I visited Hidcote Manor Gardens in Warwickshire earlier today. They have several honey bee hives and a notice board claiming three different reasons for the decline in honey bee colonies across the UK. “The number of honey bee colonies in the UK has halved in recent years. This is probably due to: 1. The use [...]

HUNDREDS of millions of dollars have been spent on fishways, resnagging, riparian revegetation, not to mention the billions for water buyback, all recommendations of the Native Fish Strategy for the Murray Darling Basin 2003-2013 [1]. Those who implemented the program, however, claim no progress, in particular that numbers of Murray cod are still in decline [...]

IT is ten years since the launch of the ‘Native Fish Strategy for the Murray Darling Basin 2003-2013’ [1]. Hundreds of millions of dollars have been spent on the program including to re-snag the main channel of the Murray River with microchip embedded logs, building fish-ways and of course returning hundred of gigalitres of water. [...]

ONE swallow does not make a spring, and the coldest spring for more than 50 years does not disprove the theory of anthropogenic global warming. *** Picture of a nesting box taken near Stratford-on-Avon yesterday.

MANY South Australians, and the Australian government, and the Murray Darling Basin Authority, claim that it is necessary to have barrages across the bottom of the Murray River because of the upstream irrigation industries [1]. There is no equivalent large-scale irrigation in Singapore, but they have barrages across the Marina channel. In Singapore, unlike Australia, [...]

HOW could scientists conclude that half of the Great Barrier Reef has been lost in the last 27 years: target coral reefs most affected by cyclones, coral bleaching and crown-of-thorn starfish outbreaks, while ignoring more representative reefs with healthy corals. And I didn’t make that up! It’s documented in a peer-reviewed study by H. Sweatman, [...]

IT was all over the news again this morning, that unless action is taken to improve water quality the Great Barrier Reef could be placed on the World Heritage list of sites in danger and by the way, there has already been a 50 percent decline in coral cover at the Great Barrier Reef. No [...]
