Common Ragwort is a native

Common Ragwort is a native plant that is highly invasive, and colonises wasteland, grass verges and fields. Ragwort contains dangerous toxins that can cause fatal liver damage to horses and livestock. Ragwort will need to be controlled when there is likelihood of it spreading onto neighbouring land.

And when we say "controlled"...

...we mean pulling up the plants by hand, being sure to get the roots out, then burning the whole thing.

Preferably in early May, well before it flowers: and after rain, so the ground is soft and they can be pulled out easily and completely.

I'm never quite sure what to do when I find Ragwort "out and about" - as a former horsey person, my urge is to rip it out!! But I don't know what the policy is, on nature reserves etc.

Cinnabar moth

Senecio jacobaea is the food plant for the cinnabar both (and some other insects), and some conservation bodies are keen to keep it for that reason.

As it stands Senecio jacobaea is ubiquitous in lowland areas - trying to eliminate it would be like trying to eliminate nettle.

Rachy Ramone's picture

Ah, conservation.

Hence the dilemma: it's a native plant, it has a "right" to be here (whether or not it is clear to us, ha ha) and no matter how poisonous it is to horses, it is bound to be the nectar of choice to some group(s) of insects.
