IMPORTANT NOTICE - Caltrop (Pest Plant)
Caltrop (Tribulus terrestris) is a summer-growing weed found widely throughout Western Australia. It is most common in areas of frequent spring and after summer rain. Under the Local Government Act 1995 it is a prescribed pest plant in a number of shires in the Perth metropolitan area, the southwest and the wheatbelt. However, it is not a declared plant, and there is no requirement to report it to the Department of Agriculture and Food, Western Australia.
