Japanese knotweed and giant hogweed
While the most common problem presented by invasive plant species is environmental (particularly affecting native flora and fauna), some are known to present an issue to human health. The various species commonly affect and/or monopolise brownfield, amenity, residential and commercial sites once they have become established. Two species in particular stand above all others when it comes to issues of disposal and the disruption they cause to building projects: Japanese knotweed and Giant hogweed.
Treatment of both plant species can be very straightforward, provided sufficient time is allocated for the treatment, appropriate guidelines are properly adhered to and a sensible approach is adopted.
