More than 173,000 people from all over the world signed the online plea saying that shooting wolves in two regions in B.C.'s Interior — one in the northeast and one along its border with Idaho — will not protect shrinking caribou herds.
The government says it plans to have hunters shoot as many as 184 wolves from helicopters this year.
Petition backers and letter signatories Pacific Wild and The Valahalla Wilderness Society argue that human encroachment is threatening caribou, not wolves.
They say limits to mining, snowmobiling and backcountry skiing would be a better way to grow the herds.
The provincial government plans to continue culling wolves by sterilizing and shooting them for four more years.
