1210 – Annual vegetation of drift lines

Habitat code:	1210
Name:	Annual vegetation of drift lines
Brief description:	Defined by the presence of a species-poor, open-structure community comprising ephemeral annual plants typical of drift lines on beaches, where winter storms deposit a great amount of organic debris.
Characteristics of Typical species:	Indicator species of drift line habitat on Tavolara are Cakile maritima, Salsola kali, and Polygonum maritimum. They define an annual halonitrophilous community tied to the availability of organic substrates on beaches, particularly Posidonia oceanica debris deposited by waves.

Threats:

The quantity, nature, and permanence of organic substrates, together with sand quality and the degree of dune disturbance, are the main ecological factors affecting this, habitat, which is negatively impacted by beach cleaning and the presence of tourists.
