The results of this PRA show that Lespedeza cuneata poses a moderate risk to the endangered area (Pannonian, Black Sea, Continental, Mediterranean, Steppic and Atlantic biogeographical region) with a moderate uncertainty. Lespedeza cuneata invades grassland, woodland, forests, edges of wetlands, pastures, and disturbed sites in the United States. The species forms dense stands in areas where it invades, reducing light availability and potentially increasing competition for soil water (Eddy and Moore 1998; Allred et al. 2010; Bauman et al. 2015). Eddy and Moore (1998) showed that invasions of L. cuneata into oak savannas in southeastern Kansas reduced native species richness. Lespedeza cuneata can have high socio-economic impacts; for instance, in the USA it can replace more palatable forage species in some systems. High tannin levels in old plants can also have negative impact on cattle and horses (Fechter and Jones 2001).

Plants for planting (horticulture and agriculture) and contaminant of hay are the main pathway for entry into the EPPO region. The likelihood of entry is low with a moderate rating of uncertainty.
