This popular landscaping plant is deadly to wildlife

IDAHO FALLS — Japanese yew is an evergreen suitable for much of Idaho’s climate, which makes it attractive for landscaping. Unfortunately, it’s also deadly.
Idaho Fish and Game officials are asking homeowners, landscapers, developers and nurseries to choose alternatives to Japanese yew, or other types of yew (Taxus), when they’re planting, especially in places where yew might be consumed by wildlife.
According to Lynn Kinter, Fish and Game’s lead botanist, “Poisonous foliage and seeds are found on all types of ornamental yew, even those called Irish yew, English yew, Chinese yew, spreader yew, or other names.”
F&G officials also ask homeowners to inventory their existing landscaping plants and replace yew if it is on their property.
“I know it’s a hassle to remove shrubs after they’re established, but doing so can save wildlife, as well as domestic animals like rabbits and horses,” Kinter said. “Elk can die from eating only a few mouthfuls of yew leaves. Dogs can die simply by chewing on the pruned branches.”
Because the dried branches and dead shrubs are also toxic, they should be disposed of in a covered landfill, she said.
If homeowners are unsure about identification of shrubs on their property, they can take cuttings to garden centers, or to Master Gardeners at University of Idaho county extension offices.
Idaho Fish and Game suggests a list of alternative landscaping plants that are suitable replacements for yew, including evergreens, natives and non-natives.
Idaho native evergreens that are non-toxic and can tolerate some shade:

Western swordfern (Polystichum munitum)

Curl-leaf mountain mahogany (Cercocarpus ledifolius)
Russet buffaloberry (Shepherdia canadensis)
Oakleaf sumac (Rhus trilobata)
