Mike’s team of Cambridge Balsam Bashers set to work on clearing the invasive weed Himalayan Balsam from a long stretch of the nettle infested lower reaches of Bourn Brook and the Mill Race (just above Granchester)
The aim is to stop infestation around Cambridge, and ultimately (ie in future years) to work back up Bourn Brook and meet up with the eradication efforts been coordinated by the Wildlife Trust and others upstream on Bourn BrookIt was noticeable that there were very few plants on the South bank, thanks to vigilance by the anglersĀ over the last few years.
Part of the lower end of Bourn Brook were also only lightly infested, because they had been cleared earlier by canoe. Canoe work can be very effective earlier in the year, before the waterweed gets too thick.
