This is the reason why invasive species are becoming targets of eradication and other interventions leading towards reducing their numbers and spread in invaded area. Despite these efforts, expansion and number of invasive alien species is growing in the world. Mainly globalization, more intensive traffic through countries and continents drive spreading of plants to new areas.There are not many examples of successfull eradication projects which led to complete removal of alien invasive plants on bigger areas.
