Steve and Heather Bond, from Pant Glas, say a field close to their home is now over-run with the Himalayan Balsam. Dr Bond said: "This non-native, invasive plant is fast becoming widespread and a major threat to our native wildlife.

Michelle Henley, reserve projects officer for the trust, said: "We are aiming to remove and control the spread of giant hogweed, Japanese knotweed and Himalayan balsam to allow native species to flourish again."
