Local councils are often caught up in the panic about ragwort. There are many many errors. Eastbourne Council are a good example.
They have Ragwort listed as a "notifiable plant". This is a common error. Often it is "notifiable weed". One thing should be made clear. There is no such thing at all in UK law. There is no need to notify anyone about ragwort or any other plant being present anywhere. You are also not automatically required to control it. For the law on Ragwort you can see this previous posting The Law on ragwort: the legislation explained.
In Eastbourne council's case they compound the panic by claiming that ragwort would contaminate compost. This is a rather silly notion.
