La popolazione di lupi nel canton Grigioni è raddoppiata rispetto all'anno precedente. Attualmente si stima che ci siano una cinquantina di animali sul territorio retico e si sono formati due nuovi branchi.
Il numero di lupi nei Grigioni è raddoppiato nel 2020

È quanto si legge nel rapporto 2020 dell'Ufficio grigionese per la caccia e la pesca. Questa rapida diffusione è affascinante dal punto di vista della biodiversità e dell'ecologia, sottolineano le autorità. I sei branchi finora presenti nel cantone hanno dato nel 2020 alla luce a una trentina di cuccioli. Malgrado l'alta mortalità dei piccoli si può supporre che la popolazione dei predatori continuerà a crescere, sostiene l'Ufficio per la caccia e la pesca.
Il gran numero di lupi comporta tuttavia delle sfide per il cantone: il loro cibo preferito sono i cervi e altri animali selvatici, ma non disdegnano neppure gli animali da fattoria. In territorio cantonale nel 2020 sono state trovate 169 carcasse di cervi, camosci e caprioli e si sono verificati 257 assalti ad animali da allevamento. Complessivamente l'Ufficio per la caccia e la pesca ha versato quasi 127'000 franchi svizzeri ai contadini come risarcimento per gli attacchi dei lupi.
