According to extensive work carried out by Swansea Friends of the Earth in conjunction with Buglife, the Invertebrate Conservation Trust, ragwort is a plant that is very valuable for biodiversity. Like many plants, ragwort contains certain poisonous chemicals and there have been cases of animal poisoning. However, it would appear that the risks associated with ragwort tend to be grossly exaggerated in the media and other publications from bodies such as the British Horse Society.
Further information can be found on the Swansea FoE website, on Ragwort blog and at Ragwort Facts.
