ANSE and Salinera Española restore the dunes of La Llana within the framework of LIFE Salinas (27/12/2019)

ANSE and Salinera Española develop restoration and reinforcement actions for the dune cord of the Llana (San Pedro del Pinatar).

The actions have consisted of fencing to prevent trampling and the implementation this year of 16,000 plants of dune species.

The Posidonia reservoir, the placement of sand catchers and the fight against invasive alien species will reduce the erosion of the sand deposit that is greatly affected by the alteration of coastal dynamics as a result of the Port of San Pedro.

The Association of Naturalists of the Southeast (ANSE) together with Salinera Española have begun the restoration and reinforcement of the dunes of the beach of La Llana within the framework of the LIFE Salinas Project (LIFE17 NAT / ES / 000184), an initiative that has the financing of the LIFE financial instrument of the European Union and with the support of the Biodiversity Foundation of the Ministry for Ecological Transition.

The restoration actions carried out have consisted, first of all, in the control of Invasive Exotic Species such as Carpobrotus and Agave americana by manual removal to avoid the impact on the native flora.

In addition, to prevent the trampling of the dune, an enclosure of 750 linear meters and about 2 ha of surface with hunting fence on wooden posts has been carried out, which will allow the vegetation to recover during the next 4 years.

With the objective of accelerating the recovery of the vegetation cover, more than 16,000 seedlings of different configurator species of the habitats of community interest of the dunes are being introduced and with special attention to the threatened species such as the dune juniper, the sea asparagus Minor, the maritime carrot or the tamarilla of the Mar Menor.

To complete the restoration of the dune complex, the front will be protected with a reservoir of Posidonia oceanica dumps and the movement of the sand in the dune cord will be reduced by installing 3,000 meters of sand collectors made with hurdle and poles of wood.

The rows of collectors will be placed perpendicular to the dominant wind, previously measured to prevent the arrival of sands to the salt ponds and encourage the growth of the dune.

The use of collectors is the best option to solve the problems of the dune habitat, since they simulate the natural process of dune formation.

In addition, part of the driftwood available on the beach after storm events has been taken advantage of in the actions to return these important elements to the dune ecosystems for the nutrient cycle.

ANSE participates in the project with five other partners - Salinera Española SA (coordinator), General Directorate of the Natural Environment of the Region of Murcia, Mãe d'água Lda., City Council of San Pedro del Pinatar, and the University of Murcia.

The main objective of this project is the conservation of the Audouin gull (Larus audouinii) and priority habitats 1510 *: Mediterranean salt steppes (Limonietalia) and 2250 *: Coastal dunes with Juniperus spp.
