In the fur trade, a trapline is a route along which a trapper sets traps for his or her quarry. Trappers traditionally move habitually along the route to set and check the traps, in so doing become skilled at traversing remote terrain, and become experts in the geography of the local area. Because of this traditional knowledge, traplines are not only of interest to trappers themselves but to researchers and others (governments, corporations) interested in local history, biology, and topography. The assignment of particular trapline territories to individuals in band societies was traditionally handled by group consensus, and occasionally violence and warfare. In the present-day trapline assignment is typically formalized and controlled by the state. Formalized trapline territory boundaries
