Tackling the alien invasion
A new web video by Clinton Devon Estates has been released on YouTube showing how local volunteers have been battling an invasive weed that is choking East Devon’s river courses.
Royal Marines from the Commando Training Centre at Lympstone are featured alongside members of the Otter Valley Association and 20 staff from Clinton Devon Estates, stripping armfuls of Himalayan balsam from the banks and tributaries of the River Otter in an attempt to stop it from spreading and smothering other vegetation.
In the film, Dr Sam Bridgewater, Nature Conservation Manager for Clinton Devon Estates, explains how Himalayan balsam has become a major weed problem since being introduced by Victorian gardeners to the UK in the 1830s. It is currently the focus of a nationwide programme of eradication.
In a race against time, East Devon volunteers have been working on the tributaries of the River Otter, pulling the weed by hand before each plant matures and disperses hundreds of seeds up to seven meters away.
The two minute video can be viewed via this link: http://goo.gl/8W9P0 or accessed via the video library on the Clinton Devon Estates website.
