Dr Kent Brooks says that 'animals do not eat ragwort', (Letters, October 29, 'Response to ragwort issue').

Richard Mabey, in his book Flora Britannica (1996), says that "horses and other animals will eat ragwort when it is dry.

"It causes irreversible cirrhosis of the liver, fresh or dry, and is fatal to cattle".

The Ministry of Agriculture says that it "causes half the livestock poisoning in the United Kingdom".

He cites A.A. Forsyth's book British Poisonous Plants (1968).

Until the 1981 Act, it was indeed an offence not to clear it. Its exemption under the Act is probably an oversight.
