The scientific community recommends that more research is needed on the postrelease effects of transgenic crops. There is also a need for more targeted post-release monitoring and better methodologies for monitoring (ICSU, FAO, 2004). The roles and provisions of these bodies are described below. This provision goes beyond the general scope of the Convention in that it requires also that risks to human health are taken into account. Invasive alien species are considered as species introduced deliberately or unintentionally outside their natural habitats where they have the ability to establish themselves, invade, replace natives and take over the new environment.
