Black oak
General poisoning notes:
Black oak (Quercus velutina) is a native tree found only in southern Ontario. The acorns contain significant quantities of toxic phenolics. This plant caused sickness and death in cattle after they ingested acorns on autumn pastures. The occurrence of poisoning from black oak in southern Ontario is minimal because of its restricted distribution (Sandusky et al. 1977, Basden and Dalvi 1987).
