Abstract I surveyed the history of exotic pasture introductions in northern Australia to compare the rate of introduction of useful species with that of weeds. For example, of 463 grasses and legumes introduced to improve pastures in northern Australia, only 5% increased pasture productivity; over 60% of the remaining species naturalized and became weeds (Lonsdale 1994). Pasture then becomes a more expensive source of feed. Although regarded as a productive and useful pasture species in summer-rainfall regions of southern Africa, USA and Argentina (Voight et al.

For most invasive species, eradication is not currently feasible, and these species are likely to remain in Australia. Silage — pasture or crops that have been cut and stored wet, in large plastic-wrapped bales or in underground pits to feed A key challenge for Australia is managing the devastating impacts that invasive alien species - including pests, weeds and diseases - inflict on our economy, environment, health and way of life. The species are arranged as an alphabetic list of species with both 'Common' name and 'Scientific' name.
