Trinity College in Dublin recently debuted a very nice internet resource for invasive plant information. The Alien plants in Ireland database, which contains over 700 species, is searchable by taxonomy, location, and invasive status. You can search for species by Latin name or in English (and supposedly French, German, and Dutch too, but I could not get those to work). The entry for each plant displays its name in multiple languages along with an extensive amount of biological information including growth form, reproductive stats (pollinators, seed dimensions) and habitat types. It is obvious that a lot of effort went into making this database, and it is sure to be a useful tool both in Ireland and around the world.
