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...
