Rush skeletonweed

Rush skeletonweed (Chondrilla junceae) is an extremely aggressive, non-native plant species that quickly takes over native habitat. This species out-competes native plants and reduces biodiversity, impacts wildlife habitat, and degrades agricultural land. Already infesting thousands of hectares in the United States, rush skeletonweed is only found in a few places in British Columbia, including the West Kootenays. Since it has no natural predators in Canada, this species will continue to spread if it is not controlled.

This spindly plant has barely visible leaves, a small yellow flower, and fluffy white seeds that are similar to dandelion. It's taproot can grow up to 8 feet long, making it very competitive with local plant species and extremely difficult to get rid of. Seeds are carried by wind and can blow to neighbouring areas, or stick onto tires to move into uninfested sites.

The CKIPC conducted an inventory of rush skeletonweed in 2005. It was found in the Slocan Valley from Passmore to Crescent Valley, Krestova, Shoreacres, and Glade. Since it is relatively contained, it is extremely important for residents and land managers to control this plant on their properties and prevent it spreading further.

Small plants can be hand pulled and larger infestations dug up. According to local resident Tex Earl Mowatt, the best time to pull the plants is when they are just about to go to seed. At this time, they are unlikely to resprout.

Plants should be burned or bagged and brought to the dump to prevent seed spread. Mechanical control is relatively ineffective for this species. For herbicide options, see website below or contact the CKIPC.
