ULAANBAATAR — Bruce Elfstrom got a first-hand look at the fragility of Mongolian nomads’ existence while producing a documentary in 2004.Elfstrom, a biologist and outdoor adventurer, was camping with a film crew and some nomadic herder families on the vast steppes of rural Mongolia. He was awakened one freezing, star-filled night by the sound of slaughter. A wolf pack had attacked the grounds, killing 17 horses and 30 other animals.Such losses are devastating but common for Mongolian nomads, who maintain a millennia-old lifestyle of small family units residing in mobile yurts, and are dependent for subsistence on livestock — traditionally horses, camels, yaks, sheep and goats.
