**Abstract:** Transitional Waters are worldwide high valuable ecosystems that have undergone significant anthropogenic impacts. The ecological assessment is therefore of fundamental importance to protect, manage and restore these ecosystems. Numerous approaches can be used to understand the e ffects of human pressures, and, in case, the e ffectiveness of recovery plans. Eutrophication, climate change and morphological loss impacts can be assessed by means of aquatic vegetation, benthic fauna, and nekton. Moreover, before planning new infrastructures or interventions, predictive approaches and statistical analyses can provide indispensable tools for managemen<sup>t</sup> policies.
