Vulpia myuros (L.) C.C.Gmel. – a recently introduced plant in Norway coming from lawn grass seed mixtures.

Since its discovery in 1983 on the roof of the iron age farm at Ullandshaug in Stavanger, SW Norway, Vulpia myuros has been found on several occasions in SE Norway. The typical localities are newly sown lawns, where the species occurs only for one season, before the perennial grass species are fully established. The species is obviously a part of an imported seed mixture much in use. On the roofs at Ullandshaug, the species has persisted since its discovery, presumably because of the dry conditions with little competition on the roof. The species has not yet found corresponding habitats in SE Norway, where it might establish persisting populations.
