Hopefully you have not encountered Japanese Knotweed yet, but if you have you are probably aware of its deadly effects on commercial property development. Fortunately environmental intelligence provider GroundSure has launched a groundbreaking report to help you spot the evidence earlier in the planning process and reduce risks and costs for your clients.

What is Japanese Knotweed?

Japanese Knotweed, or fallopia japonica as it is scientifically known, was brought into Europe in the early 19th century and became popular as an ornamental plant. Little did the importers know the future damage it would cause. It is a highly invasive, destructive plant species that can dramatically impact asset values and lending. Indeed the Centre for Environmental Studies estimates around £1.6 billion is spent every year in the process of its removal.
