•    It should be supported by funds, national as well as international cooperation to carry out research, rehabilitation, etc.
•    Determination of priorities as control target of Invasive Alien Species should cover aspects on ecology, economy and health
•    To intensify communication of involved parties in Invasive Alien Species Management among others through mail list, workshops/trainings or other scheduled meetings
