Andropogon virginicus, a grass of American origin (yet pretty widely naturalized out of its natural area) was discovered in 2006 on the military camp at Le Poteau (departments of the Landes and Gironde). The fortuitous introduction of the species is very likely linked to the storage of NATO ammunition in the camp. Andropogon virginicus seems to be perfectly naturalized there and displays an invasive behaviour. This justifies the setting up of information and communication logistics, partly supported within the framework of the Natura 2000 network. In this article, the diagnostic characters, ecology, habitat and the original and secundary distribution are presented.
