HABITAT

2230 – Malcolmietalia dune grasslands


Habitat code: 2230
Name:

Malcolmietalia dune grasslands

Brief description:

These are annual plant communities blooming in late winter and spring, occurring in a mosaic pattern with the perennial vegetation of embryonic, mobile, and fixed coastal dunes.

The plant communities that define them are the associations Malcolmio-Linarietum sardoae, Sileno nummicae-Malcomietum ramosissimae e Senecioni leucanthemifolii-Matthioletum tricuspidatae.

Characteristics of typical species:

The plant communities that define this habitat include endemic and range-restricted species of great interest.

They are dominated by Silene sp. pl. and Malcomia ramosissima on fine sands, and Matthiola tricuspidata and Senecio leucanthemifolius on coarser sands.

Linaria flava (Poir.) Desf. subsp. sardoa (Sommier) A. Terrac, a species endemic to Sardinia and Corsica, is often associated with these communities


Matthiola tricuspidata (L.) R. Br.

Silene beguinotii Valsecchi

Linaria flava (Poir.) Desf. subsp. sardoa (Sommier) A. Terrac

Threats These communities grown on sands that are not excessively nitrified or impacted by human activities, and their survival depends on limiting these factors.
