Most people think of animals such as cats and rats when you mention invasive species, however plants can also be invasive. One plant that is particularly damaging in Jersey is Japanese Knotweed (Fallopia japonica). Introduced in the late 1800s, this plant has become so deadly because not only does it penetrate walls, asphalt and drainage works, causing safety risks. But it also forms a dense canopy, which prevents other plants from growing, damaging the islands native plantlife.
