Bighead Knapweed

It is one of the many perennial knapweed species found in the Pacific Northwest region. Bighead knapweed will out-compete grasses and other forage species which can lead to a decrease in food sources for livestock. Once established, removal is difficult and costly. Large infestations of bighead knapweed will displace native vegetation and have an impact on biodiversity and wildlife habitat.
