Target 10: Invasive Species

Management Plans in Place for at Least 100 Major Alien Species that Threaten Plants, Plant Communities and Associated Habitats and Ecosystems

There is no agreed reliable estimate of the number of alien species that threaten indigenous plants, plant communities and associated habitats and ecosystems to such an extent that they may be considered as “major”.

It is recommended therefore that the target be established for an absolute number of such major invasive alien species. The wording “At least 100” is considered appropriate. The 100 invasive alien species would be selected on the basis of national priorities, also taking into account their significance at regional and global levels. For many alien species, it is expected that different management plans will be required in different countries in which they threaten plants, plant communities and associated habitats and ecosystems.

This target would be considered as a first step towards developing management plans for all major alien species that threaten plants, plant communities and associated habitats and ecosystems.
