Sažetak
North-American grass species Glyceria striata has been recorded in Europe for the first time in 1849 in France. The first observations from other European countries appeared from mid-20th century, thus in total 17 countries reported presence of this alochtonous species so far. Independent introductions to Europe have occurred more than once, most likely through mixed grass seeds from USA. Since G. striata prefers wet habitats, it is assumed that birds, water flow and human activities are the main factors responsible for its spread through the continent. According to available data, the species has not yet been naturalized on the Iberian and Balkan peninsulas. During the extensive field survey of the alluvial forests of Dinaric region, the species has been found in June 2015, for the first time in Croatia. In total 4 localities have been recorded in Gorski Kotar region (NW Croatia), close to Slovenian border. The first two were near the place Gerovo, and the other two along the Kupa River (Sedalce and Brod na Kupi). The species has been found within alluvial forest stands belonging to two associations (Lamio orvalae-Alnetum incanae Dakskobler 2010 and Lamio orvalae-Salicetum eleagni Dakskobler, Šilc et Čušin ex Dakskobler 2007). G. striata has probably arrived to Croatia from the neighbouring Slovenian populations by water flows, and has spread at least on two localities by human activities. It is, for certain, widely overlooked and ignored, due to its similarity with the grasses Puccinellia distans (L.) Parl., Catabrosa aquatica (L.) P.Beauv., and some species of the genus Poa. Currently, G. striata does not show a risk to native floras, yet it is assessed as potentially invasive species in Central Europe due to its clonal growth.
