Lypia, from Central America, has claimed half the Kirkby farm. We'd estimate we have 5-6,000 acres of lypia. Well, it's a big problem right through the whole basin and it comes from Condamine in the north, in Queensland right through to South Australia. It's appearing everywhere throughout the basin. The best way to attack lypia is by ploughing it up, but that's impossible in wooded grazing country.
Farmers fear they're losing the battle against a steady invasion of exotic plants.
