A group of volunteers in north Shropshire have said they are determined to get rid of an invasive plant which has taken root along their river.

River Perry Water Watch, based in Baschurch, is pulling up Himalayan balsam from their riverbanks, with members saying it degrades them and damages biodiversity.

The group's leader Wendy Lowdon said it was a preventative measure to stop biodiversity decay in the river, in which other species are crowded out or killed off.
