Rhu & Shandon Community Council

Local Knotweed Action

The Community Council started to record of all outbreaks in of Japanese knotweed our area and set up a Knotweed Taskforce in 2014. Its aims are listed below.

If you regularly walk in areas where the weed is flourishing and are willing to help in this exercise, please let the secretary know. ( 

 If you do not know what it looks like, we will help you identify it. Copies of the leaflet we produced are still available. You can see pictures and identification tips on the Knotweed Facts lower down this page.
 We inform Argyll and Bute Council of our findings, and ask them to set up a containment  programme for the weed. We have had mixed sucess with this.

The GB Non Native Species secretariat has also produced a leaflet.

There was a landmark case in February 2017 in which Network Rail were sued for allowing Knotweed to spread onto someonelse's land. This has implications for everyone who has a garden.

The aims and objectives of the Knotweed taskforce are listed below.

• Raise awareness of the plant, its main features and the danger it poses to the property and the environment. 
• Offer help to the Community in identification. 
• Appeal for help from the general community in locating all areas of the weed

  • Roadsides
  • Woodland
  • Seashore
  • Railway tracks
  • Gardens
