When the settlement spread to Hossa, Sámi people were living on the northern side of the area. They carried out reindeer husbandry, and the settlers adopted it from them.
In summer, the reindeer roam free. In the worst mosquito period, the reindeer eagerly withdraw
into low sheds built to protect them from mosquitoes. In early winter, the reindeer are gathered into a roundup pen for the earmarking of calves and for slaughter. Smaller reindeer traps have been used for gathering reindeer. In the Hossa area, there is a roundup pen that is still in use, as well as many pens that are no longer used.
