In recent weeks, the storms have washed a large number of Posidonia remains onto the shores of the beaches of Calafell, a vital plant for the marine cycle that is highly threatened and that we try to preserve by all means due to its essential role in the environment. .
What some might consider to be a dirt that has been removed by the sea, is actually a natural process that even reveals hope for the protection of the coasts. That the tide has brought posidonia remains to the shore may indicate that there is a prairie of the species in a nearby area.
Last year, the Anèl·lides y Oceánicos organization started a project to locate posidonia meadows in the Coma-ruga and Sant Salvador area with the aim of preserving them and promoting actions to prevent damage from launching anchors that drag the plants.
The arrival of Posidonia to the coast is after many years that it has not been seen and presumes that the plant may be recovering in the area. The councilor for Urban Ecology of Calafell, Aron Marcos, points out that a search should be carried out to try to locate meadows.
In fact, one of the proposals approved in the participatory budgets for this year is to promote the repopulation of Posidonia, to which 200,000 euros will be allocated.
The Posidonia is a guarantee for the protection of the beaches since it slows down the force of the waves and settles the seabed, in addition to being a refuge, breeding area and food for many marine species, absorbing CO2 and producing oxygen.
Calafell will promote a study to try to locate the presence of the plant. Widespread decades ago, it had practically disappeared due to the dragging of anchors, dredging to make regenerations like those of 30 years ago or the turbidity of the water due to the lack of purification.
The posidonia remains that have been removed by the sea should also be left on the shore, at least until the bathing season begins, since they form a barrier that slows down the impact of the waves as well as retaining the sand in suspension carried by the waves.
In terms of recovery, it is difficult and in some parts of the coast there are already attempts to repopulate the seabed, but it is a very slow-growing plant and is highly threatened. For this reason, it is necessary to delimit and publicize their location to try to avoid anchoring in grassland areas.
The location of possible meadows in the area that are considered could be between the ports of Coma-ruga and Cunit, will also allow monitoring to check their evolution, growth or decline and promote protection
