Pro Natura organizzerà nel fine settimana la seconda "notte delle rane". In Ticino, le occasioni per entrare in contatto con gli habitat degli anfibi saranno due: venerdì nel Sopraceneri (appuntamento alle 20.30 al parcheggio sterrato a nord della caserma di Losone) e sabato nel Sottoceneri, a Barbengo-Pian di Casoro (stessa ora, ritrovo al posteggio lago di Figino). Nei Grigioni, la scelta è fra Maienfeld (venerdì) e Val Monastero (sabato).
L'appuntamento è stato voluto per sensibilizzare la popolazione sulla sorte di rospi, rane, tritoni e salamandre, la cui sopravvivenza nel nostro paese è minacciata dalla progressiva scomparsa dei loro ambienti naturali.
L'escursione sarà guidata da un esperto e ai partecipanti si consiglia di munirsi di scarpe adatte (o stivali di gomma) e di una torcia.
