Montana Elk Calves Die After Eating Toxic Landscaping Plant

Wildlife officials in Montana are warning landowners and hunters after several elk calves in the Bitterroot Valley died from consuming a highly toxic ornamental plant. The Montana Department of Fish, Wildlife & Parks confirmed that Japanese yew, a non-native shrub often used in landscaping, was the cause of death.

The incidents occurred in mid-February when officials were alerted to multiple dead elk near residences. Necropsies revealed that the animals had ingested Japanese yew, a plant known to be fatal to livestock and wildlife. The plant contains alkaloids that can cause sudden cardiac failure, often leading to death within hours of consumption.

Japanese yew has been responsible for similar wildlife deaths in Montana before. In past years, it has killed moose, deer, and even pets. Despite its dangers, the plant remains a popular choice in landscaping due to its evergreen foliage and ability to withstand cold temperatures.

Wildlife officials are urging residents to remove Japanese yew from their properties, especially in areas where wild animals frequently roam. Alternative native plants can provide similar aesthetic benefits without the deadly consequences for wildlife.

The recent elk deaths highlight the ongoing risks associated with ornamental plants that are toxic to native species. As human development continues to expand into wildlife habitat, conflicts like this become more common. Montana wildlife managers are working to educate the public about the dangers of certain non-native plants to prevent further losses.

For now, hunters and residents in the Bitterroot Valley are being asked to report any sightings of sick or dead elk, as well as any locations where Japanese yew is found near known wildlife corridors.
