The invasive species Himalayan Balsam causes huge problems for our rivers. Herts & Middlesex Wildlife Trust are planning several working parties this summer to pull Himlayan Balsam from key locations within the catchments.
Himalayan Balsam was first introduced by the Victorians, and has since spread widely and rapidly along our river systems. It cases problems in two ways: by shading out the native, bankside vegetation, and by dying back in winter leaving the banks exposed and vulnerable to erosion.
Herts and Middlesex Wildlife Trust are planning some Himalayan Balsam pulling days, to really try and tackle this invasive species along the Beane and Mimram. These working groups are part of Beane Project 9 and Mimram Project 9. The dates are fixed, but the locations won’t decided until a few days before, based on up-to-date info collected by the river wardens about where the worst affected areas are. Landowners will also be contacted to ask permission.
The dates are:
Thurs 6th June; Fri 21st June; Thurs 27th June; Sat 20th July; Thurs 25th July; Sat 17th Aug; Thurs 29th Aug; Sat 21st Sep
All of these days will (weather permitting) run from 10am to 3pm, including a break for lunch.
