The 13th North American Caribou Workshop Winnipeg, Manitoba, Canada 25–28 October, 2010 New caribou crisis – then and now Robert A. Ruttan Box 42, Rural Route 2, Tawatinaw, Alberta, Canada T0G 2E0 ([email protected]). Abstract: The reported decline of the Bathurst herd has caused considerable concern and has raised rumours of a “crisis” in which there is a possibility of extinction. This paper reflects on relevant lessons learned from the officially declared “crisis” of population decline in 1955/56 and a second crisis of overpopulation identified by the author a decade later. Key words: Barren ground caribou; Bathurst caribou herd; Canada; crisis, management history; population decline; resource management; traditional knowledge.
