Ecological Threat
Bunias orientalis it has become a weed of cultivation, occurring on grass fields, roadside verges, and ruderal sites as well as in gardens. From these sites it can invade dry grasslands, especially neglected dry meadows. Solitary specimens to dense stands of Bunias orientalis may also be found along railways, on fallow lands and in floodplain meadows.
