Invasive species – non-native plants, insects, animals introduced into a country accidentally or deliberately are always a problem, as they disturb or destroy the checks and balances of the native ecosystem. Himalayan balsam is one of the worst invasive plant species in the UK. It grows and seeds prolifically, crowding out native plants. When it dies back in the autumn – it’s an annual, despite its size – the ground is left bare and so susceptible to erosion.

It’s of little food value for native British wildlife, but its flowers are very attractive to pollinators. That may sound like a good thing, but pollinators go to Himalayan balsam in preference to native plants, thus further hastening the latter’s decline and worsening the unbalancing of the ecosystem. It’s illegal to plant Himalayan balsam in the UK or let it spread into the wild, and reporting to DEFRA any plants found in the wild is mandatory.

The ‘Groundwork GM’ project, in association with the Mersey Rivers Trust, has organised two days – Saturdays 19th June & 17th July – to clear balsam and to plant native species along the Micker Brook (the Lady Brook, downstream). Meeting will be at 11:00am at the Shiers Drive carpark, Cheadle SK8 1HW – that’s where ‘Cheadle Village’ and Cheadle swimming pool are situated.
