2210 – Mediterranean Crucianellion maritimae fixed beach dunes

Habitat code:	2210
Name:	Mediterranean Crucianellion maritimae fixed beach dunes
Brief description:	The habitat comprises primary garrigue growing on the backdune, where sands are stable and compact (so-called grey dunes). They comprise plant communities growing on gently-sloping fixed dunes, with medium- or finely-granulated sand.
Characteristics of typical species:	The plant communities that define this habitat comprise endemic or range-restricted species of great interest. Indicator species of fixed dune habitats include Crucianella maritima L. and Pancratium maritimum L.; Fixed dune communities also comprise the endemic species Helichrysum italicum (Roth)G. Don subsp. microphyllum (Willd.) Nyman, Scrophularia ramosissima Loisel., Silene succulenta Forssk. subsp. corsica (DC.) Nyman and the following species of phytogeographic interest: Thymelaea tartonraira (L.) All. subsp. tartonraira and Rouya polygama (Desf.) Coincy.

Threats

This habitat is extremely vulnerable to dune destabilization. As such, the stability of sandy substrates and the absence of external impacts (sand quarries, trampling, off-road vehicles and machinery) are of key importance for its conservation.
