EPPO Lists of Invasive Alien Plants
EPPO A1/A2 Lists of pests recommended for regulation as quarantine pests
Invasive alien plants which have been added to the EPPO A1/A2 Lists of pests recommended for regulation as quarantine pests are listed in the table below. The purpose of the EPPO A1/A2 Lists is to recommend that organisms of serious phytosanitary concern should be regulated as quarantine pests by EPPO member countries (A1 pests are absent from the EPPO region and A2 pests are locally present in the EPPO region). The listing of pests is based on technical justifications (i.e. PRAs) and follows a meticulous approval procedure. Plant species, before being submitted to a PRA, have been identified as posing a risk by the EPPO prioritization process.

EPPO List of invasive alien plants
The plants listed below have been identified by the Panel as being absent or present in the EPPO region; as having a high potential for spread; as posing an important threat to plant health and/or the environment and biodiversity; and eventually as having other detrimental social impacts in the EPPO region. Because a large number of invasive alien plants are already present in the EPPO region, priorities were set in order to select those species considered to pose the greatest threat to species and ecosystems in the EPPO region. EPPO therefore recommends countries endangered by these species to consider taking measures to prevent their introduction and spread, or to manage unwanted populations (for example with awareness raising, restrictions on sale and planting, and control measures). This List is constantly being reviewed by the Panel (new species can be added and others removed). The List is not meant to be exhaustive but to focus on the main risks.
EPPO Observation List of invasive alien plants
The EPPO Observation List was created by the EPPO Panel on Invasive Alien Plants in 2012. This list contains plant species (absent or present in the EPPO region) which present a medium risk. This List is constantly being reviewed by the Panel (new species can be added and others removed). The list is not meant to be exhaustive but to focus on species that present a medium risk.

EPPO Alert List (extract)
Species included in the Alert List have been selected by the EPPO Secretariat or proposed by EPPO member countries, because they may present a risk to the EPPO region. Most species are still of limited distribution, or absent from the EPPO region. Each addition to the EPPO Alert List is also marked by a short article in the EPPO Reporting Service. The objective of the EPPO Alert List is to provide early warning and eventually to propose candidates which may be subjected to a PRA. Species recorded in the Alert List are assessed through the EPPO Prioritization process to determine whether they should fall into the List of Invasive Alien Plants, the Observation List, or a PRA should be conducted.
