Résumé

Attributes the failure of reindeer to return to summer ranges, after being trucked there 150-300 km from winter ranges, to destruction of the herds' social organization, the importance of uninterrupted learning of the migratory route, disorientation caused by unfamiliar winter areas, and a large proportion of inexperienced animals in the herds.
