GENEVA, Switzerland (AFP) — Swiss sheep farmers on Saturday dumped the bodies of animals killed by wolves in front of a regional government building, demanding more action against the predators, Swiss media reported.

Around a dozen breeders came from the Saint-Barthelemy area in the western Swiss canton of Vaud to lay out the carcasses of 12 sheep in front of the regional government headquarters in Lausanne, the Chateau Saint-Maire.

“These sheep were killed last night,” Eric Herb, a member of a Swiss association demanding the regulation of big predators, was quoted as saying by the Keystone-ATS news agency.

“It is really time to act.”

“We are sick of this. We want the wolf killed,” agreed Patrick Perroud, a farmer and butcher from the nearby municipality of Oulens.

“Cohabitation is not possible. Our territory is too small,” he told Keystone-ATS.

The protesters told the news agency that wolves had killed 17 sheep in the same area late last month, two earlier this week and 13 overnight to Saturday.

“The breeders have played nice until now, but this time it was too much,” Herb said.

The protesters were planning to increase the pressure on the Vaud government environment minister, Vassilis Venizelos of the Green Party, he said.
