An interfaced analysis of change of forage vegetation, nutrition of saigas (Saiga tatarica), and their state in tne steppe regions of Russia is performed. It is noted that the percent of graminoids has increased considerably and the proportion of forbs has decreased in the vegetation of current pastures, which has had a negative impact on the nutrition and state of saigas. It is shown that the lower nutritional value of graminoids has caused a decrease in the digestibility of forage used by saigas and does not provide the physiological requirements of the animals. It is established that modern steppe pastures, where gramineous communities prevail, are of little use or absolutely unsuitable for the stable existence of saiga populations. Only separate dwelling places with an abundance of forbs continue to provide adequate nutrition for saigas and well-being for their local groupings.
对俄罗斯草原地区饲料植被的变化、高鼻羚羊的营养状况及其状态进行了综合分析。结果表明，当前牧场植被中禾本科植物的比例大幅增加，杂类草的比例下降，这对高鼻羚羊的营养和状态产生了负面影响。研究显示，禾本科植物较低的营养价值导致高鼻羚羊所食用饲料的消化率降低，无法满足动物的生理需求。现已确定，以禾本科群落为主的现代草原牧场对高鼻羚羊种群的稳定生存几乎没有用处或完全不适合。只有那些有大量杂类草的独立栖息地继续为高鼻羚羊提供充足的营养，并使其群体保持良好状态。
