Management Notes (for the Swan NRM Region)

Alternative Names. Beardgrass, annual rabbitsfoot grass, rabbitfoot Polypogon.

General Biology. Growth form. Grass. Life form. Annual, caespitose. Reproduction. Seed. Dispersal. Mammals (particularly rabbits), wind, water. Photosynthetic Pathway. C3.

Notes. Naturalised in southern Africa, New Zealand, United States (including Hawaii), Canada, Central America, South America and across Australia except in the Northern Territory. Often found along wetland margins where it colonises bare areas. Produces prolific seed. Can rapidly complete its life cycle. Straw (dead material) is allelopathic.

Additional information. Origin. Europe, Asia, north Africa. Similar exotic species. Polypogon maritimus. Similar native species. P. tenellus.

Suggested method of management and control. Spot spray 1% glyphosate. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
