Monitoring of Posidonia oceanica meadows in the Sicilian coasts under the Water Framework Directive (WFD) 

 -  Firenze University Press  2020 
<br/><br/> The present paper aims to assess for the first time the ecological status of the Sicilian water bodies using the PREI (Posidonia oceanica Rapid Easy Index) method according to the Water Framework Directive (WFD, 2000/60/EC) requirements. The PREI is based on five metrics: shoot density, shoot leaf surface area, E/L ratio, depth of lower limit, and type of this lower limit. Monitoring of the 29 P. oceanica meadows allowed to classify the 20 WBs of Sicilian coasts in the first two levels of status: 10 as high and 10 as good with the PREI values ranged between 0,551 and 1.
