A global report says 21 per cent of the plants named in a new database are at risk of extinction, and 12 per cent of the world's threatened plants are in Australia.
Researchers said one of the major factors threatening the plant species with extinction was agricultural change and the need for land for urbanisation.
An Australian expert said a change in land clearing laws in Queensland had already resulted in the clearing of an estimated 200,000 hectares of threatened species, and there was concern that New South Wales could be heading down a similar road.
Professor Willis said scientists discovered an average of 2,000 new plant species each year. "We're finding new plants for food, for fuel, for drugs," she said.
