A group of volunteers have taken to the river banks in Lampeter to tackle the spread of invasive Himalayan balsam. The group of 16 volunteers have worked hard this week to control the impact of invasive non-native species (INNS) on the Lampeter Dulas – a tributary of the River Teifi.

Soil and sediment eroding from the land can fill in gaps between river gravel, smothering the habitat that fish like salmon and trout use to lay their eggs and preventing oxygen from reaching the eggs. Joe Wilkins from the West Wales Rivers Trust said: “We’re delighted with the response to our request for volunteers and are grateful to those that turned up on the day for their help.
