From the protection point of view, all sea grasses can be found on the list of the Species Under Special Protection of Andalusia“.

In addition, these are species that are characteristic of other habitats of Community Interest: “Habitat 1110: Sandbanks permanently covered by shallow seawater” and “Habitat 1140: tidal flatlands”.

Posidonia oceanica meadows constitute a priority habitat for the Habitats Directive: Habitat 1120. Since 2012, and due to the Life Posidonia Andalusia project, there has been detailed mapping of the extension of P. oceanica in Andalusia, which is utilised for the detection and selection of the best locations for the various actions to be carried out.

In relation to the Andalusian marshes, two sites of great importance in the conservation of biodiversity of Andalusia have been selected: Cadiz Bay and Odiel Marshes.

Bay of Cadiz Natural Park

This is not only a SCI (Site of Community Interest) but is also declared a Nature Park, Nature Reserve, a Special Protection Area (SPA) for birds, and a wetland of international importance (Ramsar Convention). This park is occupied almost entirely by Habitat 1140: tidal flatlands, but also in remote areas of the tidal influence there are representations of Habitat 1310: Annual halophyte vegetation on unevolved saline soils, and Habitat 1320: Spartina swards (Spartinion maritimae).

En el área protegida de la Bahía de Cádiz, se encuentran tres especies de fanerógamas marinas Cymodocea nodosa, Zostera noltei y rodales dispersos de Z. marina, si bien esta última especie está localizada fuera de la ZEC pero dentro del LIC Fondos Marinos de la Bahía de Cádiz (ES6120009).

Odiel Marshes Nature Reserve

in addition to being a SCI it is also declared as a Biosphere Reserve, Nature reserve, Special Protection Area (SPA) for birds, and a wetland of international importance (Ramsar Convention). This space is 50% occupied by the habitat of brackish or salt marsh, with the saline grasslands and salt steppes being the Habitats of Community Interest: 1310, 1320, 1410, 1420 and 1510.

In the protected area of the Odiel Marshes, Zostera noltei seagrass can be found as a part of Habitat 1140: muddy or sandy plains not covered by seawater at low tides.

The Life Blue Natura project will clarify the contribution of these ecosystems to the EU climate-change objectives.
