VOLUNTEERS gathered in Torrington to uproot an invasive plant which is a threat to native wildlife.

The event, held on the Tarka Trail, involved a group of volunteers walking to Beam Weir, where Himalayan Balsam is most common.

The plant was first introduced from the Himalayas in the 18th century and is now one of the fastest growing plants in England.

The "Bash the Balsam" day was organised by the North Devon AONB and Biosphere Service.

Andy Bramwell, who was in charge of the event, said: "The balsam is becoming an increasingly big problem throughout the North Devon Biosphere area.

"We have been pulling up the plant for years but we think it is now time to have a co-ordinated effort.

"We hope to raise awareness of the plant and the effect it can have. If more people know about it then hopefully we can stop it spreading."

The plants are pulled up once a year before the seeds ripen in July.

The process is repeated for three years, which is how long the seeds can survive in the earth.

Barry Everington, a retired police officer, was one of the many volunteers who attended the event.

He said: "I'm retired now and have got the time to help participate in events like this.

"I have a real interest in the environment and only recently enjoyed surveying burrows near Clovelly."

If it is not tackled the Himalayan Balsam can get a lot bigger, up to three metres in height in summer, and can increase the risk of river bank erosion and flooding.

This could mean there is also more mud in the river, which could cause problems for fish.

The plant grows in thick dense areas and can crowd out native plants and harm natural habitats for native wildlife such as otters and water voles.

Emma Weller, an ecology student from Newquay, was helping out at the event doing work experience as part of her degree.

The 26-year-old said: "I'm very interested in different plant species. This was a great opportunity for me to get some experience in an ecological environment."

Aidan James,20, from Bideford, also attended the event and found it a very fulfilling experience.

He said: "I believe we should keep the world around us healthy.

"I don't think we really think about the negative effects some plants can have and I want to help make a positive impact."

The event is one of three annual projects held by the North Devon AONB and Biosphere Service.

An otter holt building project was held in Bideford recently which was very successful.

Andy Bramwell, who lives in Woolacombe, added: "We have a good network of volunteers for events like this but we want to attract anyone interested in the environment and outdoors for future events."

The next Biosphere project to be held involves removing laurel at Ford Ancient Woodland in Bideford and will take place on July 12.
