First implementation of the MediSkew index in the Cymodocea nodosa meadows of the Boka Kotorska Bay (Montenegro) and assessment of the ecological status

The seagrass Cymodocea nodosa is a protected species and one of the most important habitat engineers in the Mediterranean Sea. Therefore, the assessment of the status of its meadows is of great importance for the planning of conservation measures, and the implementation of the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). This is of special importance in the areas where Posidonia oceanica is not present or does not dominate, as it is the case of the Boka Kotorska. The MediSkew index which has already been successfully implemented in the northern Adriatic Sea was for the first time tested in the Boka Kotorska Bay (southern Adriatic Sea). First results show that the ecological status at five sites is very good and good, while the status at one site is moderate. Furthermore, the MediSkew index is applicable in different geographical areas and it is sensitive to different environmental conditions, so the application of this methodology is strongly recommended for further monitoring of Cymodocea meadows and assessment of the ecological status.
