Abstract	Knapweeds are a serious problem in Oregon because they vigorously invade disturbed or degraded sites and form dense populations that exclude native and desirable plant communities, causing economic and ecological losses. Their ability to spread rapidly by seeds and roots makes control very difficult. Seeds can remain viable for 5 years or more, and once a large number of seeds builds up in the soil, it can take years to eradicate knapweeds from that site. Published September 2008. Reviewed August 2014. Please look for up-to-date information in the OSU Extension Catalog: http://extension.oregonstate.edu/catalog
