Traditionally, in the rangelands of Western Australia (WA), the pastoral industry has relied on grazing of native vegetation. However, in recent years there has been considerable interest in mosaic agriculture based on irrigated forages. There is also a potential role for improved dryland pastures in medium to high rainfall areas of the Kimberley.
Under these conditions there is increased interest in the introduction of non-indigenous species which may improve the productivity and sustainability of
agricultural systems. However, there is also clear evidence that a number of introduced non-indigenous plant species have become established in non-target
areas and some have become environmental weeds.
An Environmental Risk Framework and weed risk assessment (WRA) protocol to assess species with agricultural potential in southern Australia was developed for the Future Farm Industries Co-operative Research Centre (FFI CRC) (Stone et al. 2012). This protocol has been adapted for use in the rangelands of northern Western Australia. The refined methodology introduces the concept of ‘Inherent weed risk’. The potential distribution or land capability is considered as a separate, but integral step in the process to provide a flexible system which can assess the risk at the regional scale and also take account of the operational context.
This environmental WRA system is designed to improve the access, transparency, rigour and consistency of information available to policy makers and those considering the use of non-indigenous species and their introduction to novel environments in the WA rangelands.

Conference21st Australasian Weeds Conference 2018
OtherThe Weed Society of New South Wales Inc., on behalf of the Council of Australasian Weed Societies Inc., will be hosting the 21st Australasian Weeds Conference in the popular Sydney beach side suburb of Manly from 9 - 12 September 2018.  An assortment of field trips will be hosted on Thursday 13 September 2018.

This biennial conference carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices.

The conference attracts over 250 delegates from across Australasia and globally.  Delegates will come together to network with peers, engage with industry sponsors, listen and participate in presentations and field trips on a variety of topics including; 
- New technologies in weed management.
- Biological, mechanical, and chemical weed control and research.
- Herbicide resistance.
- Weeds of crops and pastures.
- Environmental weeds and Weeds of National Significance.
