Value of species
The distribution of S. ruderalis is incompletely known. In the Czech Republic, it is common in southern and central Bohemia, and also occurs in southern Moravia. It is currently spreading along roads, railways and rivers. Outside this country we recorded this species in southern Slovakia, Lower Austria, Hungary, Slovenia, Croatia, Serbia, Italy including Sardinia and Greece. It is probably a hitherto overlooked widespread species, especially in southern Europe.
Stellaria ruderalis is a ruderal species. It grows mainly in disturbed ruderal open or semiopen communities such as grasslands and edges of ruderal scrub and diverse types of forests and tree plantations. It often occurs along roads and railways. It is also commonly recorded along rivers, especially in urban areas and inhabits (besides ruderal habitats)
riparian semi-natural forest and shrub communities. This species grows mainly on moist to wet nutrient-rich soils on diverse, usually anthropogenic substrates, but is also recorded on alluvial deposits. We did not record S. ruderalis as a weed of crops, which is one of the typical habitats of S. media. However, both species can co-occur in other ruderal communities.These two species have very similar ecological demands. By contrast, S. neglecta is a species of semi-natural habitats such as wet to mesic, usually riparian forests and scrub. However, it also often grows together with S. ruderalis, especially adjacent to roads or railways or in the vicinity of these habitats. Finally, S. pallida is a species of sandy soils, but currently is spreading in urban lawns in the Czech Republic (Hadinec & Kaplan 2012) where we also recorded it occasionally together with S. ruderalis. The ecological amplitude of the newly recognized species is broad and overlaps that of the other species, especially, S. media.
