Ragwort is a native UK plant which is a primary food plant for the
cinnabar moth, listed on the UK Biodiversity Action Plan as rapidly
declining.


Ragwort is now classed as a noxious weed and there are legal consequences if
you don't pull it up.


I think the attributions have got mixed and I'm not sure who wrote this.
Could whoever did please provide a reference to the legislation that
classifies ragwort as a noxious weed and describes the legal
consequences of not pulling it up?

I am not aware of it being covered by legislation other than the 1959
Weeds Act (which I described in the snipped portion of my post) and the
Ragwort Control Act 2003 which provide for a Code of Practice to prevent
the spread of ragwort.

The code of Practice can be found at

http://www.defra.gov.uk/FARM/wildlif...op_ragwort.pdf

and I quote: "This code does not seek to eradicate ragwort. Ragwort, as
a native plant, is very important for wildlife in the UK. It supports a
wide variety of invertebrates and is a major nectar source for many
insects. In many situations, ragwort poses no threat to horses and other
livestock. It is natural component of many types of unimproved grassland
and is used by some invertebrate species that have conservation needs.
However it is necessary to prevent its spread where this presents a high
risk of poisoning horses or livestock or spreading to fields used for
the production of forage. A control policy should be put into place were
a high and medium risk is identified"

This is a long way from it being "notifiable to the local authority" as
was stated in the post I originally replied to, or there being "legal
consequences if you don't pull it up." - this would apply only if you
failed to control it in a medium or high risk situation.

Finally, all this legislation applies only to Senecio jacobaea (Common
ragwort) and not to the various other species of ragwort, marsh, hoary
etc.


Cinnabar caterpillars do prefer ragwort but can also feed on grasses.


Can you provide a reference for this? I know it can feed on groundsel
and other species of Senecio, but I have never seen reference for it
feeding on grasses.
