Railway volunteers have helped to rid a nature reserve in Stockport of one of Britain’s most invasive alien plant species.
A dozen Network Rail staff joined forces with members of the Gatley Carrs Conservation Group to stop destruction caused by Himalayan Balsam.
The non-native weed, which has a stronghold on local rail embankments, risked infesting the local beauty spot which is wedged between the railway and the M56 motorway.
Riverbanks, railways and waste land are the perfect breeding ground for Himalayan balsam to spread rapidly.
It greedily gets an early start in spring and quickly shades out native plants so that by summer it has often taken control of the entire habitat.
Every plant has pods containing more than 500 seeds each which then explode in the autumn, allowing seedlings to set root up to seven metres away.
To combat it, the volunteers took part in a process known as ‘balsam bashing’ pulling up the invasive weed before its seed pods are big enough to burst.
Chris Sutton, an ecologist at Network Rail who took part, said: “Usually you have to call in specialist contractors to clear Himalayan balsam, so we were happy to use our volunteer leave to lend our graft and knowledge, and help reduce these costs.
“This invasive plant is a huge blight on the railway and native biodiversity in general so anything we can do to share best practice and slow the spread in beauty spots like Gatley Carrs is the least we can do.”
Emma Burrows, from the Conservation Group, said: “A great day’s work and a huge bash on the balsam, thanks to Network Rail and their volunteers for helping to keep this invasive plant under control.”
