Legislation

Under Section 14, Schedule 9 of the Wildlife and Countyside Act 1981 it is an offence to cause Japanese Knotweed to spread.

Under the Environmental Protection (Duty of Care) Regulations 1991 and Environemntal Protection Act 1990 Section 34, soil contaminated with Japanese Knotweed is classed as 'controlled waste' and must be disposed of in registered landfill sites.

Problems caused by Japanese Knotweed
Japanese Knotweed causes a variety of problems facing both the natural and built environments.  In many instances the plant causes more than one problem on a given site.
With regard to the built environment Japanese Knotweed shoots are able to push through tarmac and concrete, potentially damaging various utilities and facilities.  Rhizomes have been recorded penetrating foundations and walls, lifting interlocking concrete blocks, including flood defence revetments, causing a wide variety of damage with high associated costs, which could become recurring expenses unless the Japanese Knotweed is controlled.

Growth and Spread
Japanese Knotweed (Fallopia japonica) is an invasive non-native weed.  Rapid growth rates and an ability to grow in a variety of conditions, coupled with the regenerative ability and persistence of the rhizomes make Japanese Knotweed a difficult and often expensive problem facing developments and are the main reasons for its status as one of the UK's most pernicious plants.
An established clump of Japanese Knotweed has an extensive system of underground rhizomes, which can reach some 2 metres in depth and up to 7 metres beyond the edges of stands.  It can also grow at a rate of several metres per year.
