Invasive Non-Native species cost the UK £1.9 billion per year and contribute to 60% of global biodiversity loss. Himalyan Balsam is a major threat to local wildlife, it outcompetes native plants, increases the long-term flood risk and destabalises riverbanks and accelerates riverbank erosion.
Every year we fail to act Himalyan Balsam spreads dramatically. Our mission is to empower people with the confidence and tools to tackle Balsam where they live.
