UK -- Protecting a wetlands of scientific interest

Edie.net, via Hydro Defender: The precarious wetland habitat at Shortwood Pond off the A308 by the Crooked Billet roundabout is home to endangered species such as the Brown Galingale plant and the Little Whirlpool Ramshorn snail…

...."Increasing road traffic contributes to this pollution, and there was also no protection from a major spillage event. Working with Hydro, we have found the Downstream Defender® is ideally suited to protecting the pond, because it separates out and retains the sediments. The entrapped solids and sediments are not washed out by high storm flows as they would be in conventional gully pots. The hydrocarbons and floatable portions are also retained.

"The project was completed within a tight budget and kept to a small foot print. Apart from chamber emptying, maintenance is minimal. In fact we were able to oversize it to allow for up to 50 litres/sec and help to protect the site against future large storm events."

...Staines Moor is one of the remaining pastures of the manor of Staines, having been unploughed for at least 1000 years and common land since 1065. Given its precarious location between Staines and other conurbations, preservation of the quality of the habitats in this river valley is of high importance to the Spelthorne Borough Council, Plantlife UK, Colne Valley Park, Groundwork Thames Valley and the Environment Agency.
