Japanese stiltgrass is an invasive annual grass native to Asia that has spread throughout the eastern US. It grows in a variety of habitats and can dominate forest understories, reducing diversity and restricting tree growth. While it pulls up easily, stiltgrass is difficult to eradicate due to long-lived seeds and spread through water, animals, and human activities like equipment. Effective management requires controlling it before seed production using herbicides, mowing, or burning, along with preventing further spread through equipment sanitation and regional coordination of control efforts.
