Abstract
By the Global Strategy for Plants Conservation, adopted in April 2002 at the Hague, as a component part of the Convention referring to the Biodiversity (Rio de Janeiro 1992) it was recommended to set up by the end of 2004 national lists of alien invasive plants, and to work out until 2006 measures for controlling the most aggressive of these. Such lists have already issued in a series of countries. After consulting a great lot of bibliographical sources and based on the field observations of the authors, these have drawn up for Romania a list of 435 alien species, archaeophytes as well as neophytes. For every species apart are given the time period of immigration, the invasive statute, abundance, type of habitat where it is found, the affected type of landscape, the mode of introduction, life form, origin, author and year of first citation in our country. These data allow the identification of the most aggressive alien species in conditions proper to Romania, and represent a support for measures of prevention and control due to be worked out.
