Aliens in the Anthropocene: 4% of the global flora is somewhere an alien

According to study published in Nature (and see Nature Editorial), iDiv scientist Marten Winter, who is among the core co-authors, says that almost 4% of the global flora become naturalized somewhere in the world outside of its native range due to human activity. "We analysed 481 mainland areas and 362 islands and found almost 13.200 plants being not native there." GloNAF (Global Naturalized Alien Flora) is the name of the database behind those results and was started to live 4 years ago. "We already published other analyses with parts of GloNAF."
