Question: are yew trees poisonous to sheep?
Answer: The genus Taxus consists of three commonly grown ornamental shrubs — English yew, Canada yew and Japanese yew — and hybrids. The needles and seeds of all yews are highly poisonous to horses, cattle, sheep and goats (Figure 1), although the red, fleshy seed cov- ering is not. ... Yews, fresh and dried, are toxic year round.
