Alien flora of Europe: Species diversity, temporal trends, geographical patterns and research needs
International audience; The paper provides the first estimate of the composition and structure of alien plants occurring in the wild in the European continent, based on the results of the DAISIE project (2004–2008), funded by the 6th Framework Programme of the European Union and aimed at “creating an inventory of invasive species that threaten European terrestrial, freshwater and marine environments”. The plant section of the DAISIE database is based on national checklists from 48 European countries/regions and Israel; for many of them the data were compiled during the project and for some countries DAISIE collected the first comprehensive checklists of alien species, based on primary data …
Alien Species of EU Concern in Romania
AbstractOf the 37 species of the European Union concern eight are already present and two present a future potential risk for Romania. This paper brings updated information regarding these species in Romania. The presence of eight invasive alien species of concern to the European Union have already been recorded in Romania: two plant speciesCabomba carolinianaandHeracleum sosnowskyi, two crustaceansOrconectes limosusandEriocheir sinensis, two fish speciesPseudorasbora parvaandPerccottus glenii, one reptileTrachemys scriptaand one mammalMyocastor coypus. Other two species of Union concern (Lithobates catesbeianusandProcyon lotor) may soon become invaders in Romania. We emphasize the urgent n…
