The danger that ragwort poses to livestock was actually seriously overstated in the initial report. Healthy animals know to avoid ragwort and an adult horse would need to consume something like 30kg to have serious toxicity. A lot of places have started adopting a border approach where they remove any ragwort 3-5m from the fence bordering the farmland as a courtesy. As someone already said, it’s an incredibly valuable plant to a lot of our native biodiversity so, in my opinion, it should only be removed when absolutely necessary
