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.

Students in the Department of Landscape Architecture and Horticulture’s Senior Design Studio have circled an important date on their calendar in December — and it’s not the one you might be thinking.
On Thursday, Dec. 10, the 27 students will present their design concepts for Cape May, New Jersey’s Rotary Park, Harborview Park and a new biking and walking trail linking all of the historical shore point’s unique features.

Environmentalists are disappointed that another plan for Alberta‘s water resources pushes back to at least 2012 a strategy for protecting wetlands.
“After a decade of debate and the loss of thousands of hectares of wetlands in Alberta, we can no longer afford to delay taking action to protect our wetland resources,” said Danielle Droitsch, executive director of the conservation group Water Matters.

Annapolis intends to test a floating island in a local lagoon that, if successful, could help clean the water in the Chesapeake Bay, according to Mayor Ellen O. Moyer……
Floating islands are created from recycled plastics and planted with wetland plants that soak up nutrients from the water, said Steve Carr, the city’s environmental adviser. He said the project in Annapolis will act as a test to see whether the technology can be implemented in larger areas of the bay.

The European Union is asking Spain why one of its precious wetland reserves has been allowed to dry up so much that the peat which lies beneath the surface is on fire.
Ecologists blame the mismanagement of water resources and over-irrigation for the environmental tragedy in the Tablas de Daimiel National Park, which is part of a UNESCO biosphere and has EU protection.

Last Friday saw the dedication of 112 acres to further expand the current 2,900-acre Las Vegas Wetlands Park. The land was acquired along the east end of Tropicana Road through funding acquired from fining developers for disturbing environmentally sensitive areas.
Currently the price tag for works at the Wetland Park has reach $80 million with a further $15 million needed for future projects such as a nature center with interactive displays.
