To promote a co-ordinated approach to the control and management of Fallopia japonica (Japanese knotweed, donkey rhubarb) and its hybrids in Cornwall through partnership.

The Forum has produced a number of publications and guidance notes, organised conferences and co-ordinated research projects. It has developed a GIS (graphical information system) survey recording system in conjunction with the Botanical Society of the British Isles. The assistance of many town and parish councils in supplying information is gratefully acknowledged.

The Forum is interested in receiving details of any infestations of Japanese knotweed in Cornwall.  Use the online form below to report sightings of knotweed thought to be within Cornwall Council's control.
