Bonesgate Balsam Bash- Hogsmill River

July 12 @ 10:00 am - 12:30 pm


Activity Description: The Bonesgate is a tributary of the Hogsmill River and is one of the upstream sources of  Himalyan Balsam, an invasive plant that takes over river banks, outcompeting other plants and causing bank erosion. Join us to don waders and enter the river channel to pull these plants up by hand.

Meeting point: Entrance to the Bonesgate Open Space, Filby Road, Chessington, KT9 2AG.
