Widespread in the U.S. Holcus lanatus is present in every state (including AK and HI), except WY, SD, NE, MN, and FL. Apparently, it causes more negative impacts in the western U.S. but more information is needed. Holcus lanatus forms dense swards that reduce native species richness and eliminate native grasses and forbs. Allelopathic activity is suspected. Holcus lanatus has become a major problem on western Oregon and Washington grassland preserves. Elimination of the plant is difficult due to its perennial nature, its ability to regenerate from decumbent tillers even when cut to only 2 cm above the ground surface, and it enormous seed bank. More information is needed, especially about trends in distribution and abundance, and management difficulty (NatureServe 2007). Could be a future problem in grasslands and open forest canopy situatioins at OBRI (RE 2007).
