Since 1992, 16 conferences have been held on the theme “Ecology and Management of Alien Plant Invasions” (EMAPi) around the world in which more than 650 identified species have been the subject of presentations. At least one presentation on 31 of the 36 species considered to be among the most invasive plant species worldwide has been made. Reynoutria japonica Houtt., Impatiens glandulifera Royle and Heracleum mantegazzianum Sommier & Levier were the species with the greatest number of studies but the majority of studies present data on only one species. Studies on the identified species have been done in 102 countries or territories around world. This reflects the different venues of the conferences and the origin of the participants in the meetings. In this evaluation, studies on the presence of identified invasive species were slightly more frequent than studies on control and management or ecology but there are many general presentations focusing on management of invasive plant species. The majority of the studied species were terrestrial with a perennial life style and were herbaceous. The majority of these species also had the capacity for vegetation spread or regrowth. EMAPi presentations are a representative subset of research on invasive plant species.
