U udaljenim arktičkim predjelima Rusije, uzgajanje irvasa praktikuje se već vjekovima. Svake zime, “pastiri” okupljaju irvase u torove, prije nego što odaberu slabije primjerke koji će biti odstranjeni. Smanjenje krda pomaže očuvanju krhke tundre, a lokalno stanovnišvo prodaje meso, krzno i rogove irvasa, od čega zarađuju za život.
