Japanese Knotweed – Locations Needed

[Benc]

Hi,

I am currently conducting a photographic project concerning invasive species and would like to document sites where Japanese Knotweed is present, particularly in the London area.

Any specific locations that people are aware of where there is a current population of the weeds would be much appreciated. I am not going to be disrupting the weeds, but simply documenting them.

Thanks for your help, I am going to be away for a week from tomorrow, so will reply to your posts on my return.

Regards,

Ben

My son had it in his house in Uxbridge when he moved in in 2010 - repeated applications of roundup has got rid of it though.

12 years ago, when I lived in Woolwich, there was a massive infestation of Japweed at the eastern end of Plumstead Common, in the Grosmont Avenue area - getting on for a couple of acres of it. I've no reason to think it's not still there.

Are you interested in Giant Knotweed?

Given how much was spent in clearing the Olympic Park of this plant I'd have thought there must be many locations along the Lea. I'd also suspect that it will crop up every few hundred metres or so along other waterways.

Your local library may have a copy of the LNHS publication on London's Plants from 1983.

Hi, thanks for the comments and suggestions.

Tursiops2, thanks for this tip-off I think I will head down to Plumstead Common to investigate...

If anyone has any more sightings or suggestions they would be gratefully received!

Thanks. Yes, I would also be potentially interested in sites with Giant Knotweed, do you know of any?

Yes, the river Lea is a good suggestion. I have explored parts of it, but I could certainly look further away from the olympic park and surrounding area which now seems all clear.

Thanks
