Coastal dune systems are accumulations of dry sand located next to the beaches and generated by the winds. They are dynamic ecosystems that host an important biodiversity of flora and fauna. Additionally, dune systems have structural and functional characteristics according to their environment. They constitute a reservoir of sand for the beaches, slowing down the erosion that can occur due to changes in currents or storms and stabilizing the coastline.
Although dune systems are changing ecosystems, they tend to have a certain permanence as they are fixed by vegetation, with species adapted to the sandy substrate.
The Regional Park of the Salinas and Arenales de San Pedro del Pinatar is a wetland that is separated from the Mediterranean Sea by a coastal dune cord. Its degradation can lead to the total alteration of the saline circuit and the loss of the habitats it houses.
Therefore, within the framework of the LIFE Salinas Project, sand collectors are being used to stabilize the dunes. These collectors will slow down the wind speed, will be able to accumulate a greater quantity of sand and will prevent the sand from being lost in the salt ponds. To reinforce the dunes, plantations with native vegetation are being carried out, which will also eliminate the paths created by passers-by. To complete its success, a perimeter fence was installed in December 2019, which was reinforced with Posidonia oceanica banquettes last June.
These repopulations with autochthonous species will also increase the absorption of carbon dioxide from the atmosphere, becoming another measure to mitigate climate change.
