Using vegetation as a bioindicator in urban and degraded areas is an effective way to assess the status of the environment.

Abstract

Using vegetation as a bioindicator in urban and degraded areas is an effective way to assess the status of the environment. In this work, we present the results of a phytosociological investigation of a suburban river and of its surroundings in southern Tuscany (Bestina river and its tributary Bestinino in Asciano, Province of Siena). By means of 94 phytosociological relevés, we identified 34 plant communities belonging to 17 classes. Six habitats included in the 92/43/EEC Directive, plus two habitats recently proposed for inclusion, were identified, as well as one habitat of regional interest. The study revealed that, despite the high levels of human disturbance, aquatic and herbaceous riparian vegetation is still well-preserved, though mostly represented by stress-tolerant communities. On the contrary, most of the vegetation types not being directly linked to the river dynamic are in poor conservation status. Despite this, some habitats of community interest were detected even in non-riverine sites. Our work provides the basic knowledge for future restoration of the Bestina river and of its surroundings, wished by the Tuscany Region.
