Riverbed Vegetation Control Programme 2016/2017

Adjacent property owners and other users of the river channels listed are advised that helicopter and ground-based spraying is to be carried out within the flood fairways of these rivers. This is to control vegetation which may affect the passage of flood water.

Plants targeted throughout the programme are gorse, broom and self-sown willow.
