Dorking Balsam Bash – River Mole
July 1 @ 10:00 am - 2:00 pm

Activity Description: Volunteer with us at Puddenhole and Castlefields in Dorking to help remove the invasive plant, Himalayan balsam, from the top of the banks of the River Mole.
Himalayan balsam is a big problem for river banks up and down the country. In addition to bringing competition for pollinators, this non-native invasive plant competes with native plants 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 on the fields down from the south side of Reigate Road A25, along from Hillier Garden Centre, Brockham, Dorking RH4 1NP, just over Deepdene Bridge, look out for the SERT Flag. Google map HERE

We will be only working from the banks of the river. We will provide tea, coffee and biscuits but please bring a bottle of water and a packed lunch.
