Paesaggi senza architetti del paesaggio. La bellezza ecologica dei paesaggi urbani informali

infrastrutture verdi, soluzioni basate sulla natura, vegetazione spontanea, leggere le tracce, microhabitat urbaniAbstract
Per la progettazione e manutenzione delle infrastrutture verdi urbane le Pubbliche Amministrazioni seguono modelli e archetipi estetici di decoro urbano accettati dalla cittadinanza, mentre i paesaggisti cercano di riprodurre isole di vegetazione a elevata ‘naturalità’, anche quando le condizioni ambientali delle aree urbane non lo permettono. A lungo termine, in entrambi i casi, i diversi obiettivi e le differenti visioni delle infrastrutture verdi urbane comportano inutili costi di manutenzione poiché ciò che definisce l’identità di un’area verde è l’uso prevalente che si fa della vegetazione. L’obiettivo di questo contributo è analizzare la composizione floristica e il significato ecologico degli habitat stradali nel caso studio della Città Metropolitana di Catania (Italia), insistendo sul valore estetico delle aree verdi stagionali a basso costo (spontanee) e biodiverse.
