A lone reindeer is separated from the rest of the herd as native villagers actively corral and cull them. Since being introduced in 1920, reindeer have freely roamed Nunivak Island, where the lone native village of Mekoryuk (population 300) is situated. Each winter, reindeer are herded by snow machine to corrals, where they are harvested to provide food for locals as well as for export. Strict population management methods are imposed, as the herd size can fluctuate wildly from year to year based on weather and food resources.
