Japanese Knotweed

Lord Clark of Windermere Excerpts

Tuesday 10th November 2015 Lords Chamber

[Lord Gardiner of Kimble]

My Lords, my noble friend has certainly been tenacious and persistent in dealing with a real thug of a plant. We have had this plant since 1825, when, with good will, it arrived at horticultural gardens; 20 years later it arrived at Kew and was sent up to Edinburgh. I am afraid that we have the consequences of not understanding, as we do now with hindsight, that we should never have allowed this plant to come to these islands.

[Lord Clark of Windermere (Lab)]

My Lords, as the Minister has said that certain local authorities have successfully dealt with Japanese knotweed, what is to stop other local authorities dealing with it in the same effective manner?

[Lord Gardiner of Kimble]

My Lords, the noble Lord hits on something as regards where it is seen to be a local priority. I should say that this is about local authorities in partnership with householders and landowners in a real community effort. I acknowledge that in Bristol, for instance, 95% of Japanese knotweed surveyed is under management. Cornwall County Council is a leader in tackling Japanese knotweed and is committed to controlling the spread of the plant. These are examples of how, with local action groups, we can make a real difference.
