It is the largest transplant of Posidonia oceanica ever made in the Mediterranean so far. A painstaking intervention, in compliance with the prescriptions of the VIA Decree of the Ministry of the Environment, and preparatory to the construction of the Porto Torres barricade.
Over the past 10 months , over 140,000 cuttings, distributed over an area of 7,000 square meters in the work site area, have been explanted and replanted in a more suitable area of the coast .
A unique intervention of its kind, the one envisaged by the Sea Port System Authority of Sardinia, in the research agreement with the Department of Architecture, Design and Urban Planning of the University of Sassari, the participation of the companies Sealives and I 7 mari, the supervision of the Port Authority and the monitoring of ISPRA and Arpa Sardegna.
The work, articulated in various phases, envisaged the collection of the plants from the mouth of the port, their movement ashore for the selection of the cuttings and their transport to the Abbacurrente area for the transplantation, carried out manually, on 250 biodegradable geomats, for an area of more than 11,500 square meters of seabed .
Precisely to guarantee its proliferation, the new area where the Posidonia dwells was banned from fishing and anchoring with a specific ordinance from the Harbor Master's Office.
As a continuation of the interventions envisaged by the provisions of the Ministry of the Environment, the Sales company, which was awarded the contract for the construction of the barricade, will provide, already in the next few days, and again on behalf of the AdSP, the positioning of 6 anti-trawl bollards to protect the 'planting area and 15 of the park. The fish restocking will instead be completed with the positioning, in the seabed delimited by the bollards, of 75 3D printed concrete modules, which will reproduce the natural habitat of the species present in the park.
The entire area covered by the interventions will be monitored for 5 years .
These steps precede the interventions to safeguard the military fort of the II World War of the Levante pier and the relocation of the Madonnina and which will start at the same time as the definitive delivery of the works on the Barricade , for which the renewal of the Evaluation document is awaited of Environmental Impact, submitted by the AdSP, for updates, to the Ministry of the Environment in the month of January.
«With the movement of the Posidonia meadow we have finally completed a very long, complex and onerous part of the activities envisaged by the VIA Decree for the start-up of the building site of the Antemurale - says Massimo Deiana , President of the Sardinian Sea AdSP - VIA Decree which has burdened the Port System Authority with interventions that are sometimes too burdensome and distracting with respect to the final objective which is that of carrying out the work. However, we have complied with an activity so far unique in the Mediterranean, particularly virtuous due to the positive effects on the health of our sea and which we will keep under monitoring for the next 5 years. In any case, our main objective remains that of starting the construction site immediately, the green light for which is subject to the release of the update to the VIA decree, which has been being drawn up since January by the Ministry of the Environment».
