Future directions and issues for the national surveillance of weeds, insects and plant pathogens in Australia

摘要

Weeds are among the most serious threats to Australia's natural environment and primary production industries. They displace native species, contribute significantly to land degradation, and reduce farm and forest productivity. Australians spend significant time and money each year combating weed problems and protecting ecosystems and primary production. From 1992 to 2010, there were 23 incursions of prohibited or regulated weeds detected in Australia. In 2011 alone, 11 new or potential weeds were officially recorded in various states.
