Activity Description: Join us during London Rivers Week at Six Acre Meadow to help remove the invasive plant, Himalayan balsam.

Himalayan balsam is a big problem for river banks up and down the country. In addition to competition for pollinators, native plants must also compete for light, nutrients and space, leading to an overall reduction in biodiversity. Moreover, the fact that the balsam dies back in the winter means that it leaves river banks bare and susceptible to erosion, and the dead leaves and stems can also cause blockages, which lead to flooding.

What’s more, each plant can produce up to 800 seeds per year – and one plant can propel copious amounts of that seed a distance of up to seven metres. This seed can spread considerably further if carried by the river, making it certain – if unchecked – to be more widespread year on year.

Meeting point: Meet at the entrance to the Hogsmill Open Space, just off Knollmead, Surbiton, KT5 9QN. Google map HERE

What to bring: Please wear appropriate clothes and footwear. If it is hot, please bring a hat and suncream. There will be options to work from the bank or in the water in waders. We will provide tea, coffee and biscuits but please bring a bottle of water and a packed lunch.
