Here's the real irony - Governments introduced it and now have to control it.
Sericea was promoted in the past to control soil erosion and provide forage for livestock and wildlife. It has been planted by both federal and state agencies on flood control dams, channelization projects, rights-of-way on highways, county roads, and private roads. From these plantings, sericea has been spread by animals and hay into native prairies, shrublands, forests, and introduced pastures. Reliance on single management practices such as grazing, burning, or spraying herbicides does not control sericea lespedeza adequately. However, initial reports indicate that integration of burning, grazing, and applying appropriate herbicides can help manage sericea and ultimately benefit the health of native plant communities, introduced pastures, cattle production, wildlife habitat, and biological diversity.
