Panicum effusum
Also called Branched Panic, Diffuse Panic, Effuse Panic, Hairy Panic, Poison Panic
Panicum effusum, commonly known as hairy panic, is a grass native to inland Australia. It occurs in every mainland state, as well as New Guinea. In dry conditions, the fast-growing grass can become a tumbleweed.
Found across Australia, particularly in the east and Papua New Guinea, hairy panic occurs on low- to medium-nutrient clay soils over shale or conglomerate. Its large range, abundance and stable population mean that hairy panic is classified as Least Concern on the IUCN Red List, and in fact may be becoming more abundant.
Hairy panic is a component of pastures, though not usually abundant. It is of moderate nutritional value to livestock. Sheep consuming large quantities of hairy panic within 2–6 weeks of rain can suffer from photosensitivity and the fatal disease called yellow-bighead.
