Invasive plant species: “black” list of species established by the Swiss Commission for the Conservation of Wild Plants

The EPPO Working Party on Phytosanitary Regulations and Council have agreed that EPPO should develop activities in the field of invasive alien species. It is recognized that quarantine pests are one category of invasive alien species, but that EPPO activities should be extended to other invasive alien species which may present risks to cultivated or wild plants. Therefore, from now on the EPPO Secretariat will try to gather information on invasive species, including in particular invasive plants.

In Switzerland, the Swiss Commission for the Conservation of Wild Plants has gathered a “black list” of invasive neophytes which are particularly aggressive and harmful for the environment (including for certain species risk for human health, indicated below with an asterisk). It is clearly stated that present populations of these invasive species should be reduced as much as possible and that any further spread should be avoided.
