The integration of indigenous knowledge with state wildlife management goals poses risks of distortion and erroneous translation. Technical or methodological challenges can further distort this integration. Nevertheless, there are many documented instances of successful co-management of wildlife resources. This critical analysis of co-management focuses on a case study of the Ruby Range Sheep Steering Committee in the southwest Yukon. While much indigenous knowledge was collected about Dall sheep, this knowledge, even when expressed in a scientifically compatibile way, was not integrated into wildlife management. This is attributed to underlying political issues.
