Bid to eradicate knotweed in Newcastle

Bid to eradicate knotweed in Newcastle

6 November 2013

NEWCASTLE is to feature in a pilot scheme aimed at eradicating Japanese Knotweed.

The plant is listed as one of the world’s 100 worst invasive species with its root system and strong growth capable of damaging concrete foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites.

The knotweed recently appeared at a flood retention wall built along the banks of the Burren River in Newcastle close to the Meadowvale housing development.

Residents in the area are concerned at the appearance of the weed.

South Down MLA Sean Rogers hopes it can be eradicated once treated with a product recommended by a leading biological scientist.

Dr. Catherine McGavin, from Queen’s University’s School of Biological Science, joined Mr. Rogers and Rivers Agency officials for a recent meeting in Newcastle to discuss the weed.

The MLA explained he has been in discussion with various agencies since the summer about the “very serious threat” the Japanese Knotweed poses to the Newcastle area.

He said his concerns were heightened recently when he learned the weed had been spotted on a flood wall at the Meadowvale development, located off the Tollymore Road in the resort.

The MLA said while he was advised the Rivers Agency was confident the flood wall was sound enough to cope with the weed, he arranged a recent site meeting with officials from the organisation.

“Also attending the meeting was Dr. McGavin, with Rivers Agency officials agreeing to run a pilot scheme using a product the biological

scientist suggested to treat the knotweed,” explained Mr. Rogers. “I wish to thank her for taking the time to come to Newcastle and feel that her expertise in this area is invaluable.”

Councillor O’Boyle, who was also at the recent site meeting, described the outcome as a “very positive step forward.” She said she will continue to work closely with the Rivers Agency and have involved Down Council officers as well. 

She added: “The way we treat this weed in Newcastle could lead the way in other areas where it is also growing.”

Laura Devlin, who works as a constituency manager for Mr. Rodgers, said she is pleased the Rivers Agency is now treating the invasive weed with the concern that is needed.
