Invasion of Himalayan Balsam along the banks of the River Severn in Shropshire. Originally introduced to the UK as an affordable garden plant in the 19th century, because of its aggressive seed dispersal and high nectar production it has become a highly invasive species. By out competing native species it reduces bio-diversity. Photographed near Shrewsbury, UK.
