Saplings have been planted alongside the canal below Sham Castle Lane.
Concerned residents have contacted Cllr David Martin after British Waterways felled several trees on the canal cutting, opposite Sydney Wharf.
British Waterways, who operate the canal, had cut down trees which they felt were diseased or unsafe. However, when David got in touch they realised that they had been too drastic. Thanks to his intervention they have replanted the site with native saplings. The species were recommended by the B&NES arboricultural officer and will in time replace the fauna lost.
