There are currently 1,377 non-native plant species within the UK; disturbingly, 8% are considered invasive.
Invasive non-native species (INNS) can disrupt our native plant and animal species, threatening biodiversity, ecosystems and habitats – resulting in serious environmental and economic damage.

Japanese knotweed (Reynoutria japonica syn. Fallopia japonica) is a weed that spreads rapidly. In winter, the plant dies back to ground level, so it is a good time to start thinking about this problem plant. By early summer, the bamboo-like stems emerge from rhizomes deep underground to shoot to over 2.1m (7ft), suppressing all other plant growth.
