Examinations of the bears’ stomach contents revealed yew plant matter, and further lab analysis ruled out other possible causes. Tests for pesticides, antifreeze, euthanasia drugs, and other environmental toxins all came back negative, confirming plant poisoning as the definitive cause.
Though accidental, the incident served as an important reminder about the risks some plants pose to wildlife. Conservationists and wildlife officials emphasized the need for public awareness, particularly in suburban and rural areas where native animals may unknowingly encounter hazardous plants.
The case, while tragic, underscores the delicate balance between human landscaping choices and the natural behaviors of animals that live nearby.
