Il cigno reale è un animale senz’altro maestoso e molto amato anche in Svizzera ma la sua veloce riproduzione, visto che non ha nemici naturali, sta creando non pochi problemi. Per questo motivo, il Consiglio degli Stati, con il sostegno del Consiglio federale, ha adottato mercoledì una mozione di Paul Niederberger (PPD/NW) che chiede di abbassare la soglia di protezione di cui gode il grande volatile.
L’animale, pur non essendo originario dell'Europa, gode di un'elevata protezione in Svizzera. Le conseguenze della rapida espansione di colonie risiedono nel fatto che gli escrementi del cigno reale creano danni enormi alle coltivazioni agricole.
Il Consiglio federale, ha dichiarato la consigliera federale Doris Leuthard, si dice pronto a vagliare la mozione nel quadro della prevista legge federale sulla caccia e la protezione dei mammiferi e degli uccelli.
