La natura si sta riprendendo gli spazi lungo le autostrade, lasciando più spazio alla biodiversità. È quanto accade nella Svizzera romanda, dove si traccia un primo bilancio di un progetto pilota avviato quattro anni fa: da allora le aree erbose vengono tagliate di meno.
Il risultato? "Vediamo il ritorno di uccelli nidificanti, la presenza di nuovi insetti e una vegetazione più diversificata" ha spiegato, mercoledì, Ewin Egger, responsabile del progetto per il Servizio di manutenzione autostradale nei cantoni Vaud, Ginevra e Friburgo.
Un recente sondaggio di Pro Natura aveva svelato che la popolazione svizzera tende troppo a valutare come buona la biodiversità in Svizzera. Ma la situazione è in realtà tutt'altro che rosea.
