Diggers have been clearing a Fenland pond after an invasive plant species was dumped there.
Kier Living has dredged the pond in the centre of Elm after Parrot’s Feather was discovered there, but concerns have been raised about the impact on wildlife.
A Kier spokesman said: “The ponds at the front of the development were contaminated in late 2014, when a fish tank of Parrot’s Feather – a non-native plant which is banned from sale in this country – was emptied into the water.
“Since then, we have been carrying out maintenance works to remove this and New Zealand Pigmyweed from the ponds. This work is vital to ensure the invasive weed doesn’t spread to other watercourses and we have agreed a comprehensive remediation programme in accordance with Environment Agency guidelines and in association with the Hundred of Wisbech Internal Drainage Board.
“A specialist contractor is relocating the fish and amphibians to ensure the environmental impact is minimal. We are in contact with residents to keep them informed.”
