Rush skeletonweed (Chondrilla juncea) is an invasive plant. It was first detected in Oregon in 1984.
Rush skeletonweed is a threat to irrigated lands and to the sandy soils of dry land wheat areas. It impacts the cattle industry when rush skeletonweed displaces native or beneficial forage species grazed by livestock and wildlife. Forage production is lowered when rush skeletonweed successfully outcompetes beneficial species for limited resources, particularly nitrogen.For more information about this plant pest, see the CABI data sheet.
