Mike why do you think small knotweed is less abundant at this site than it was previously?

There is less bare ground. There is much more Persicaria (but that is mainly where there would have been water previously) and cudweed. I didn't notice Lythrum. It would be good to get rid of the spear thistle because there is quite a bit of that.
