Ancient wild reindeer pitfall trapping systems as indicators for former migration patterns and habitat use in the Dovre region, southern Norway
The distribution of ancient reindeer pitfall trap systems suggests an extensive regional migration of reindeer between seasonal pastures in parts of southern Norway. The migration routes were funnelled by natural barriers across a high, rolling mountain plateau. In the Dovre area, two pitfall trappi...

The distribution of ancient reindeer pitfall trap systems suggests an extensive regional migration of reindeer between seasonal pastures in parts of southern Norway. The migration routes were funnelled by natural barriers across a high, rolling mountain plateau. In the Dovre area, two pitfall trapping systems, totalling at least 1547 individual pitfalls, were identified and measured using a standard procedure and GPS to record location. Migrating reindeer typically cross over valleys between areas of higher ground and reindeer pitfall trap lines are therefore aligned along the valley, individually placed so that their long axis is perpendicular to the direction of the valleys. Pitfall trap systems for moose are also evident in the landscape. In contrast to reindeer, migrating moose mainly follow the line of the valley. Pitfall rows built for moose trapping are therefore placed mainly across the main direction of the valleys, and the individual pitfalls are also larger than those intended for reindeer. Migration and lichen utilization are important factors in reindeer adaption to limited food resources and existence in marginal mountain habitats. The trap systems and their ecological context support the hypothesis of ancient large-scale reindeer migration over the west-east Dovre axis between summer pastures and winter grazing land. This migration has ceased entirely because of increasing traffic on the north-south railway and highway and probably also because of reduced reindeer populations.
