Need and opportunity for a North American caribou knowledge cooperative

The importance of migratory caribou (Rangifer tarandus) to northerners, the increasing pressure to extract non-living resources, and predicted global climate change have led researchers, managers and resource users alike to f ocus on how to improve our knowledge of this unique northern ungulate. Unpr ecedented threats to caribou sustainability, along with the increasingly ac knowledged value of indigenous hunters' contribution to caribou research, p ose the additional challenge to innovate research methods that accommodate differing cultural perspectives and facilitate communication among groups. This paper surveys the state of scientific knowledge of the eleven major no rthern mainland herds of North America. We recommend an approach to improve our working knowledge of barren-ground caribou in order to assess better f uture impacts. The transfer of knowledge gained from years of research and indigenous experience on many aspects of caribou ecology should be evaluate d and, where applicable, transferred to herds with more modest databases. T he establishment of a North American Caribou Monitoring and Assessment Syst em, based on a synthesis of local knowledge and research-based science, is recommended as a tool for improved communication and collective learning.
