Posidonia oceanica meadows form the most representative community of the Mediterranean shores. However, Posidonia oceanica meadows are fragile and in a bad way because of pollution and other nuisances. In several areas, Posidonia meadows have been replaced with vast deserts of dead ‘mattes’ or sand and mud. We owe to Cooper, now dead, the idea of using derelicts of Posidonia to regenerate the meadows in the areas where the aggressive factors were eliminated. For that purpose he perfected a kind of concrete frame called ‘constraint’ which offers optimal conditions for these cuttings to take root. So a study of scientific evaluation of Cooper's method has been undertaken in an experimental field of about 10 000 m 2 in the bay of Cannes. The ‘constraints’ were implanted over a period of 10 years, which gives particularly favourable conditions for studying their development. The work consisted of quantifying the vitality and the capacity of development of these cuttings with the help of classical tests such as the number of foliar bundles by surface unit, the biomass, the productivity, the number of running rhizomes and the surface of conquered ground. The results prove the effectiveness of the method which is now operational on a large scale. We can now foresee and hope for a reconquest of the ruined bottoms, provided of course we first remove the causes of the disappearance of the natural meadows of Posidonia oceanica.
