Australian scientists have announced the world’s first successful large-scale restoration of a coastal wetland being devastated by acid runoff.
The acid crisis at East Trinity began in the 1970s, when developers drained and cleared 800 hectares of tidal wetland to grow sugarcane. This dried out underlying acid sulfate soils causing them to release slugs of acid whenever they were soaked by rain, leading to fish kills and loss of wetlands which alarmed local residents.
A dramatic improvement in environmental conditions has been achieved by researchers working on the trial Hills Creek catchment at the East Trinity site near Cairns in Queensland, using a combination of natural tidal action and strategic treatment with lime.
Mangrove and wetlands are returning, birdlife is flocking to the area and fish abound in creeks that once ran so acid that nothing could survive in them. Having first demonstrated success in the trial catchment, remediation is underway on the remainder of the site.

Autodesk has launched a online guide and game to educate the public about buildings, carbon footprint through a online game called Retrofits. Autodesk uses gameplay to educate people about buildings and how retrofitting with double glazing, solar panels and other features can reduce the carbon fooprint of a building.
The guide - Guide to Sustainable Design for Architecture, Engineering & Construction for its Autodesk products is interesting as it creates an easier way to determine what products are best for retrofits, new buildings and determining goals. The list is also useful as BIM becomes more and more apart of a designers toolbox.

The Sustainable Sites Initiative launched the Guidelines and Performance Benchmarks 2009 in November 2009 has received more recent press coverage from the December issue of Biocycle magazine. The article looks at the history of the Initiative and explores the Ecosystem as a Baseline. The article also looks at the pilot program and the industry acceptability of the Performance benchmarks. for a good read go to the article at the Biocycle – Performance Guidelines for Sustainable Sites – Vol.50 No.12 Pg. 32
Remember that pilot program applications need to be submitted by February 15.
