Successionally-young dune grassland is found on the dry slopes of the hind-dunes – sometimes near the tops of the dune ridges on older and more stable systems. These young grassland habitats typically have a visible presence of bare sand and some cover of Cladonia lichens, notably C. foliacea, and mosses, particularly the sand-hill screw-moss (Syntrichia ruraliformis). This droughted habitat is also colonised by a specialised spring and summer annual plant flora that cannot compete in more closed habitats: these include some increasingly rare species like the early sand-grass (Mibora minima) and locally scarce species such as Hutchinsia (Hornungia petraea) and dune pansy (Viola tricolor ssp. curtisii). This habitat, and the species associated with it, will become increasingly rare as the dunes continue to stabilise.
