The Gitksan and Wet'suwet'en of Northwestern British Columbia formerly used landscape burning to manage patches of black huckleberry (Vaccinium membranaceum), the most important plant resource of their seasonal round. In view of its significance one might postulate that managed sites would conform to a biophysical or ecological type to maximize return for effort. However, a survey of a number of traditionally managed sites indicated that managed sites are characterized by wide variation in biophysical attributes including elevation, aspect and moisture regime, while proximity to fishing sites, village sites, or sites for harvest of alpine resources proved to be a common factor in known historic berry patch sites. We conclude that characterization of the ideal site type for aboriginal V. membranaceum management must include the economy and social institutions of the local First Nations and requires an enhanced appreciation for the sophistication of the strategies and techniques employed in their management and utilization of the species.

Background: The use of plants for healing by any cultural group is integrally related to local concepts of the nature of disease, the nature of plants, and the world view of the culture. The physical and chemical properties of the plants themselves also bear on their selection by people for medicines, as does the array of plants available for people to choose from. I examine use of medicinal plants from a "biobehavioral" perspective to illuminate cultural selection of plants used for medicine by the Gitksan of northwestern British Columbia, Canada.
