Knotweed clean down area

[woody paul]

Is this about transferring knot weed to another site then disinfectant will not do, or just soil transfer contamination.

I wouldn't even try to eradicate it - like our OPM  sites,   it can be controlled and covers yr duty of care via reporting and records, but as to clearing a site totally- adjacent to other sites 'less well cared for' it ain't realy possible. K

Local national park & some other regions in Wales has a mapping system for invasives, but i know thats only the tip of the iecberg as iv'e seen loads of knotweed sites that aren't recorded on the map

Kind of think a national map would be good.

 

Local council pays alot too contractors for control but it all doesn't seem very coordinated e.g the need too revist sites repeatedly, so seems most invasives are spreading alor faster than they are being "contained" or elimnated.

I think you will Stere - its like Oak moth, a lot of landowners an LA's don't want to know . Our moths are moving around year to year , they don't like pruned Oaks or pollards , and as we have over 500 on our lists , it shows year on year . K
