| description | This article presents the results from the long-term Water Framework Directive monitoring of <i>Posidonia oceanica</i> in the Valencian Community, Spain. A total of six areas where <i>Posidonia</i> occurs were studied. Locations were characterized by a different ecological condition: degraded <i>Posidonia</i> meadows; meadows in good conditions; meadows close to the best reference conditions. The spatiotemporal variability of different indicators were sampled from 2005 to 2017. Lower quality meadows are characterized by a lower density and coverage of <i>Posidonia</i>, a higher proportion of dead <i>Posidonia</i>, a higher proportion of plagiotropic rhizomes, smaller shoots, and higher epiphyte biomass, as well as the presence of foliar necrosis marks. For all study sites, the temporal trends indicated a decrease in the quality of the meadows from 2005 to 2011 and a recovery from 2012 to 2017. Some variability observed in the indicators such as <i>P. oceanica</i> cover in patchy meadows, could not be explained by changes in the meadow health. |
