Mossman River grass (Cenchrus echinatus)



Mossman river grass, native to Central America and southern North America, is an annual grass growing to 80cm. It spreads by seed in burrs. Burrs are spread attached to animals, clothing and bags, and burrs float and are moved by water. Germinates spring and summer in temperate zones. A weed in about 35 countries and is still spreading around the world.

Mossman river grass prefers sandy soils especially along the coast; provides good grazing when young, but is a major weed if allowed to mature. Burrs reduce the value of wool and make shearing hazardous. Spines of burrs also penetrate hides lowering their value. Mossman river grass competes for moisture, nutrients and light. Burrs are also a problem in recreation areas.
