QUEBEC — The caribou are now the subject of an acrimonious dispute between the Canadian and Quebec governments over how to protect one of the country’s iconic animals. The woodland caribou — whose populations are native to Canada and are considered a barometer of the health of its boreal forests — are at risk of becoming extinct or endangered as logging, mining and other human activities have shrunk their natural habitats. The Canadian government threatened this summer to use emergency measures to protect the three herds in Quebec. It said that the Quebec government had been too slow to come up with a plan to save the herds. Quebec said that the federal government’s plans would devastate logging towns and leave thousands of people jobless by limiting logging. …The Innu of Pessamit are seeking to create a protected area where the remaining 200 caribou can continue to live freely — and eventually make a comeback.
