Dollis Brook Toe-boarding removal project / vegetation management

January 20 @ 10:00 am - 2:00 pm


Below is an example of Himalayan Balsam: very pretty purple flowers but damaging to our native habitats, and it takes over anywhere the ground is wet.

THAMES21 are removing the outdated toe-boarding from the Dollis Brook along Brook Farm Open Space, and we need volunteer help from the community.

There are many tasks that we need help with on this project, but for this particular event we will be focusing on invasive species removal exclusively. This will involve a fairly long walk, just over 2k in waders along the Dollis Brook so a reasonable level of fitness is required for this event, and isn’t suitable for under 16’s.

What you need to bring with you: sensible clothes for the weather (warm layers, and a rain jacket), please bring a water bottle, and a sandwich or something for lunch, alternatively there are shops on Totteridge Lane near the site.

We will provide all the require kit you need for the event, such as waders, tools, PPE, and refreshments (tea, coffee and biscuits to all volunteers).

We will provide project information and a health and safety briefing to all volunteers on site.

Meeting location will be: Dollis Valley Estate, Leeside (road name), postcode area EN5, on the path next to the Dollis Brook itself. What3words location simply.priced.scale
