Over the last few months, there seems to have been a substantial increase in reports of the spread of Japanese knotweed in the Narberth area.

The speed of growth and damage its roots can cause to masonry and buildings is quit alarming.

County Clr. Wynne Evans said: "I have asked for a structural survey to be carried out on the wall of the old graveyard leading to Narberth bridge which is owned by the town council.

"As well as land in their ownership at Narberth bridge, private landowners have the responsibility to act to eradicate the knotweed, and having spoken with colleagues within the Environment Agency, I would refer people with concerns to check out the Environment Agency website for advice and guidance on how to remove this plant.

"Any reports of the knotweed on county council land will be dealt with directly by the local authority."
