Bamboo vs. invasive plant species
The UK Wildlife and Countryside Act 1981 (Updated 11 December 2014, now the Guidance to Invasive Non-native Plants) does not classify bamboo plants as invasive plant species.
The Anti-social Behaviour Act of 2003 covers tall hedges but it does not cover garden plant invasion.
The Anti-social Behaviour, Crime and Policing Act, 2014 enables local authorities and police to issue community protection notices where plants cause damage to neighbours’ gardens and properties.
The protection notice can be issued when it is shown beyond doubt that the individual in question has persistently acted in a way that has a detrimental effect on the quality of life of those around them.
