... Numerous marine introductions into Australian waters have occurred and will continue to occur. The mechanisms by which they occurred and the difficulties of eradication once they have become established are discussed. Introduced species are often categorised as being either a pest or cryptogenic...

... Accidental introductions into the marine environment have been either by hull-fouling or ballast water. While a large number of species has been introduced accidently (more than 150 species are known), only a few are classified as pests. Four selected for discussion are the Seastar Asterias...

... Pests are often viewed as having consistently strong and negative effects on biodiversity values and agricultural productivity, especially if they have been introduced from elsewhere. However, pests do not necessarily have just negative impacts, and there is evidence that in some situations...

... The Rural Lands Protection Act 1998 , unlike its legislative predecessor, requires the Crown to control pest animals declared under the Act. It establishes conditions that must be met before animals can be classified as pests and before pest animal control obligations can be introduced...

... a system for preparing ‘Feral and Introduced Predator Control Plans’ that aims to balance ecological sustainability with legal compliance and social expectations. This strategic approach towards vertebrate pest management relies on a scientific direction, achievable performance measures and collaboration...

... With their introduction into Australia beginning in the early nineteenth century deer have joined a long list of introduced species, many of which have become significant pests. Unlike rabbits, feral pigs, foxes and others, deer have not been considered to have had significant adverse...

... The tropical redclaw crayfish Cherax quadricarinatus is increasingly being reported as an aquatic pest in parts of the world where it has been introduced or translocated. In this paper, we briefly document the invasion of a stream system in New South Wales, Australia. We discuss possible...

... In Australia, the introduced house mouse, Mus domesticus , causes obvious and severe agricultural damage, particularly during mouse plagues where population densities may exceed 1,000 mice/ha. The aim of any pest control is to reduce the damage caused by the pest, not to reduce pest numbers...

... Invasive animals include introduced and native animals that have or may become overabundant and pose threats to agriculture, the environment or human health and safety. Following its successful bid to the Australian Government's Cooperative Research Centres Program, a new Invasive Animals CRC...

... Deer were introduced into Australia by acclimatisation societies in the late 19 th and early 20 th centuries to enhance the aesthetics of the local environment and provide sport. Several of these populations survived and formed the basis of larger, well established wild deer populations. Deer...

... because those species are now so abundant. How can balance be regained in western New South Wales? Pest species will have to be controlled; but it is not simply a matter of removing the offending animals and re-introducing the vanished (if extant). Firstly, key habitats for species must be identified...
