specifically on invasive alien species (well established)
{6.1.3}, which also increases the risk of biological invasions 
for neighbouring countries (well established) {6.3.2.1}. Only 
17 per cent of countries have national legislation for 
biological invasions, whereas an estimated 69 per cent have 
biological invasions-specific legislation as part of legislation 
in other sectors (well established) {6.1.2, 6.1.3}. Although 
many agribusinesses do not manage the risk of the plants 
they trade (established but incomplete) {5.6.2.1}, in some 
cases the business sector has developed voluntary codes of 
conduct in tandem with government regulations (Box 
SPM.1) (well established) {5.4.1, 6.3.1.4(4), Box 6.7}. It 
should be noted, however, that voluntary codes of conduct 
are intended to complement, not replace, obligations within 
national legislation that regulate activities that transport, sell 
or use alien species (well established) {6.3.1.4(4)}. The
