The Mongolian plateau is a hotspot for mammals and a perfect environment for nomadic herding. The long-term co-existence with the local wildlife is nowadays threatened by a recent drastic increase of livestock numbers, and associated modifications in the ecosystems. Official hunting and livestock data were used to understand historical links between certain selected species (grey wolf, red fox, corsac fox, ground squirrels and marmots, vs. cattle, sheep, goat, horses and camels), during the period 1941-1985. Significant interactions appeared, like negative effects of goat numbers on wolves hunting. These models were thereafter used to predict the consequences of the increase of livestock in the period 1986-2015 on wildlife. A sharp decrease of wolves and corsac foxes was predicted, and positive effects on marmots, squirrels and red fox; i.e., beneficial for ecosystem-engineering borrowing species, but negative for predators. These predictions agree with the current situation, except for marmots which are currently declining.

蒙古高原是哺乳动物的热点地区，是游牧的理想环境。如今，与家畜野生动物的长期共存受到近期牲畜数量急剧增加以及生态系统相关变化的威胁。官方狩猎和牲畜数据用于了解某些选定物种（灰狼，赤狐，科萨奇狐狸，地松鼠和土拨鼠与牛，绵羊，山羊，马和骆驼）之间的历史联系。出现了重要的相互作用，例如山羊数量对狼狩猎的负面影响。之后，这些模型被用于预测1986-2015年期间牲畜数量增加对野生生物造成的后果。预计狼群和科萨克斯狐狸的数量将急剧减少，并对土拨鼠，松鼠和赤狐产生积极影响。即 对生态系统工程的借用物种有利，但对捕食者不利。这些预测与当前情况一致，除了土拨鼠目前正在下降。
