Northern bison sanctuary or big ranch? Wood Buffalo National Park

Wood Buffalo National Park claims many distinctions: it is North America’s biggest national park (and the world’s second biggest at 44,807 km² ), a UNESCO World Heritage site, home to the largest free-roaming herd of wood bison, the first federal park in Canada’s territorial north, summer home to the last major migratory flock of whooping cranes, and the largest dark-sky reserve on the planet. These accolades may lend themselves to a popular image of remote wilderness, but the park’s wildlife has also been subject to some of the most intrusive and ill-conceived management interventions in Canadian history.

The Hay Camp abattoir (1952)

The Canadian government established the park in 1922 to protect a remnant herd of wood bison (a sub-species of the American plains bison), setting aside a large area of boreal forest plain that straddles the border between the province of Alberta and the Northwest Territories. Preserving the bison did not necessarily mean “hands-off” management, however, as government officials soon hatched a scheme to transport thousands of plains bison from the fenced and overstocked Buffalo National Park (a former park in southern Alberta) to the supposedly understocked range of Wood Buffalo National Park. Zoologists in Canada, the United States, and Britain vigorously and almost unanimously opposed the plan, fearing the loss of the wood bison sub-species to hybridization and the transmission of tuberculosis from the infected herds in southern Alberta. But government officials stubbornly persisted, transporting 6,673 plains bison to Wood Buffalo National Park between 1925 and 1928.

By the late 1940s the dire consequences zoologists had predicted had mostly come to pass. The plains bison had bred freely with the wood bison and infected them not only with tuberculosis but also brucellosis (a disease causing intense fevers and miscarriages among pregnant females). Federal wildlife officials attempted to manage their way out of past mistakes, conducting annual round-ups and testing of bison so as to slaughter diseased animals. To provide revenue for the program, the government sold salvageable bison meat to northern trading companies and, increasingly, to meat packers, hotels, and restaurants in southern Canada. Between 1951 and 1967, wildlife managers killed four thousand park bison and distributed nearly two million pounds of meat. Periodically, the goals of disease control and commercial development came into conflict, particularly when the federal government’s northern administration began to actively promote bison meat as part of a much broader program of economic development in the region.

Management controversies did not end with the cessation of meat production. In the 1970s the government held roundups to inoculate against spontaneous anthrax outbreaks among bison herds, a practice that led to high herd mortality and criticism from local Aboriginal communities. In the 1980s federal wildlife managers proposed the complete eradication of bison from the park so as to reintroduce disease-free herds after a period of ten years. An environmental assessment of this plan revealed intense opposition from local Aboriginal groups, the Canadian public, and even within the government, forcing the mass slaughter proposal to be abandoned. But if the bison of Wood Buffalo National Park were no longer subject to eradication, neither had they been preserved in anything remotely resembling an untouched state. Subject to intensive management, infection, and hybridization, the wood bison remind us that the fingerprints of human intervention work their way deeply into even the most remote wilderness national parks.
