The origin of Rosa rugosa Thunb. is in East Asia, where it occurs along sand and gravel coasts of the Pacific Ocean. The species was introduced to gardens in Europe and it started to naturalize during the 19th century (Bruun 2005). Nowadays it has become widely naturalized especially in North and Northwest Europe including the Baltic Sea (Bruun 2005, Hill et al. 2010, Kelager et al. 2013). R. rugosa has invaded in coastal habitats, like sand dunes, but also vegetated shingle, grassland, low scrub and verges also in inland habitats
