When do risk assessment of organisms?• When someone would like to release a new or modified organism, eg
GMO or synthetic organism
• When someone would like to introduce an exotic organism to Australia, eg exotic pasture species, ornamental plants or a biological control agent
• When we have to assess possible risk to native organisms, crops or domestic animals, eg during a disease outbreak
• Namely, when there are uncertainty and a valuable environment.
Risk assessment of organisms
Assess the likelihood and consequences by considering
• the organism and
• the environment potentially affected by the
organism and
• their interaction.
Likelihood assessmentInvasiveness of the organism.establish – reproduce – spread
Susceptibility of the environment to invasion.resource availability and suitability – presence of stressors
