Effects of Wind-Hardened Snow on Foraging by Reindeer (Rangifer Tarandus)
Various methods were investigated for assessing the relationship between wind-hardened snow (upsik) and forage availability to reindeer. Mean bottom area of individual craters was not a function of depth, hardness or integrated hardness. Individual crater area was partially dependent on specific cra...
