Pro Natura ha inaugurato sabato a Cartigny (GE) la Riserva naturale della Petite Grave. La zona è classificata come sito di riproduzione per gli anfibi di importanza nazionale. L'area diverrà, in particolare, il regno dei rospi.
Il numero di questo genere di animali è in calo, ha specificato Isaline Probst Schaer, coordinatrice a Pro Natura. La particolare specie di rospo fatica a trovare un ambiente adatto al suo sviluppo; proprio per questo è stata creata la speciale riserva a pochi passi a sud dalla città di Calvino.
Lo spazio della Petite Grave era stato acquistato all’asta nel 2009 da Pro Natura grazie ad un lascito. Diversi anni di lavori si sono resi necessari per ristabilire la situazione a Cartigny, dopo l’uso del terreno per diverse attività economiche e la sua trasformazione in zona naturalistica. Il progetto è costato circa 2 milioni di franchi.
