A floating island to combat blue-green algae has been installed in Shornden Reservoir as part of Hastings Borough Council’s commitment to improving the quality of water flowing through Alexandra Park.

Lead councillor for environmental services, Colin Fitzgerald, commented: “The skilfully-constructed island is like those installed in the lower park three years ago … pre-planted with aquatic plants and … with a cage to take barley straw during the warmer months.

For many years the water in this area of the park has been affected by blue-green algae, which occurs naturally in many waters nationally. The barley straw breaks down to release a natural substance that helps reduce the bloom the algae produce, which can be harmful to animals and people. The Council and Environment Agency monitor the waters for signs of the blue-green algae and will advise the public if and when any future outbreaks are confirmed.

The island will be a great wildlife habitat, will help promote beneficial microbes and filter the water through the plants’ roots, allowing silts and other water-born particles to be broken down.”
