How do you control a space invader? The problem of Japanese Knotweed in Northern Ireland

Since the introduction of Japanese Knotweed as an ornamental plant in the nineteenth century, it has spread throughout watercourses, transport routes and waste ground, out-competing native plants and damaging buildings and infrastructure.

A clear and present danger: Plant disease and invasive species

These factors also increase the potential risk of the threats that we face diversifying and affecting a wider range of plant species.

At the beginning of the last Assembly mandate in 2011, the Research and Information Service wrote a piece on the possibility of new legislation for Northern Ireland, ‘Climate Change: the need to raise the game’ [page 90 | PDF | 4.7mb]. Five years on, the climate change debate still remains and legislation specific to Northern Ireland has not yet been introduced. However, discussions around the introduction of legislation have more recently picked up momentum again.
