Abstract
Following the restoration of a Posidonia oceanica meadow impacted by theConcordia shipwreck, we investigated the spatial dynamic of the most important andprotected Mediterranean endemic seagrass over a two-year period applying three spatialmetrics: number of patches, mean patch size and total cover. By means of underwaterphotomosaics, we noticed a diminution in the number of patches in favour of the mean sizeand total cover. The outcomes showed that, under suitable environmental conditions,P. oceanica colonizes rapidly the dead matte substrate. This study underlines the importanceof considering the spatial dynamic of transplanted seagrasses in monitoring programmes andgives new insights on the progression rate of transplanted P. oceanica.
