This conference program provides details about the 17 North American Caribou Workshop. It contains the agenda and abstracts for all presentations. Scientific and Indigenous Knowledge have well established that most caribou populations are experiencing declines across North America. Caribou is an iconic species and holds a special significance for all North Americans – its status concerns us all. In order to improve the likelihood of long-term persistence of this remarkably diverse species, an unprecedented level of commitment, collaboration and cooperation among groups involved in the conservation of caribou is required. Working together is of the utmost importance. Under the unifying theme of ‘Working Together’, this conference served as a forum for knowledge-sharing and learning, providing opportunities for the expansion of networks and the fostering of new collaborations.
