4.5. Introduced Flora

Plant species have been introduced to benefit agriculture or agroforestry, to avert soil erosion and provide windbreaks, and for a range of commercial and economic purposes. Where these species escape from cultivation, they can quickly become problematic. Many noxious weed species occur in or are gazetted for the Mid Murrumbidgee. Some of the more notable are listed below:
• African boxthorn (Lycium ferocissimum)
• Alligator weed (Alternanthera philoxeroides)
• Annual ryegrass (Lolium rigidum)
• Barley grass (Hordeum spp.)
• Bathurst burr (Xanthium spinosum)
• Horehound (Marrubium vulgare)
• Paterson’s curse (Echium plantagineum)
Large infestations of several of these species occur within the region.
