Un lupo dotato di trasmettitore GPS ha attraversato a nuoto il Lago dei Quattro Cantoni durante uno dei suoi spostamenti attraverso la Svizzera. Lo riferisce la Fondazione Kora, che monitora i movimenti del canide.
L’esemplare, identificato come M637, è stato equipaggiato con un radiocollare GPS alla fine di ottobre 2025. Da allora, secondo la fondazione, ha percorso diverse centinaia di chilometri, spostandosi dal Giura vodese, attraversando parte della Svizzera, fino all’Emmental e al Canton Zugo, per poi fare ritorno.
Come dimostrano i dati registrati dal dispositivo, mercoledì il lupo ha attraversato a nuoto il Lago dei Quattro Cantoni invece di aggirarlo. Ha percorso circa 1,5 chilometri in acqua a una temperatura di 5 gradi, precisa Kora.
Secondo la fondazione, l’osservazione di un lupo che nuota in un lago di queste dimensioni rappresenta un caso unico in Svizzera e dimostra il valore della raccolta sistematica di dati sui movimenti della specie.
Grigioni, abbattuti 35 lupi
