dog-tooth wattle, dogtooth wattle, golden glow wattle, half-moon wattle, knife acacia, knife edge wattle, knife leaf wattle, knife leaved wattle, knife wattle, knife-edge wattle, knife-leaf wattle, knife-leafed wattle, knife-leaved wattle

Origin

Native to some parts of eastern Australia (i.e. the sub-coastal and inland parts of New South Wales and southern Queensland).

Naturalised Distribution

Sparingly naturalised in the ACT and naturalised beyond its native range in the coastal districts of northern and central New South Wales.

Notes

Knife-leaved wattle (Acacia cultriformis) is regarded as an environmental weed in the ACT and those parts of New South Wales that are outside its native range. It grows naturally from Narrandera in inland southern New South Wales, north through the western slopes regions, to the Stanthorpe-Inglewood area in sub-coastal south-eastern Queensland.

This species is listed as an environmental weed in the wider Sydney and Blue Mountains region and is of particular concern on the Cumberland Plain in western Sydney. Knife-leaved wattle (Acacia cultriformis) is also seen as a potential threat to the survival of the endangered button wrinklewort (Rutidosis leptorrhynchoides) in the ACT. Non-indigenous native trees, such as knife-leaved wattle (Acacia cultriformis), can form dense stands in the plant communities occupied by this species and have to be managed to maintain the open mixed-age/species woodland habitat required for the growth of button wrinklewort (Rutidosis leptorrhynchoides).
