The lightning reconquest of France by the wolf has provoked a civil war within French Greens, pitting one of the country's most renowned campaigners against environmentalists, some of whom are demanding his ousting from the movement.
Wolves have been seen this northern summer for the first time since the 1920s in the sheep-rearing area in Lozere in the southern Auvergne, the home of Roquefort cheese.
Jose Bove, sheep farmer-turned-environmental campaigner, has called for the wolves to be shot, provoking protest from other French Greens, who point out that the grey wolf is protected by European law.
One wildlife protection group has filed a legal complaint against Bove for "inciting the destruction of an endangered species".
Pierre Athanase, president of the Association pour la Protection des Animaux Sauvages (Aspas), said: "Ecology means biodiversity. If Mr Bove can't understand that, he should leave the [Green movement]."
