Boaters call for action as invasive floating pennywort blocks the River Avon
Überblick
Boating communities and marina representatives in Gloucestershire are demanding urgent action to remove the invasive non-native plant floating pennywort from the River Avon. The plant, which can grow up to 20cm a day, is wrapping around boat propellers, causing damage, and completely blocking waterways in certain areas. While the Environment Agency states that responsibility largely falls on adjacent landowners, it has established a Catchment Action Group alongside organizations like the Avon Navigation Trust to help coordinate removal efforts with volunteers.
