Sorry I've not been following the thread properly, but some folk living
nearby have an outbreak of this stuff and wonder how to get rid of it:

Came across a patch of this growing locally to me yesterday. It's the first
of this dreadful, invasive weed that I've found in Cambridge. I plan to eat
some (it's very like rhubarb, if you get it when it's really small and know
how to prepare it safely) but I'm not planning to single-handedly take the
weed on.

What's the best approach to take to see if our local council/conservation
organisations might be interested in controlling this stuff?

Any ideas anyone please?
