Saiga antelope regularly undertake long-distance movements varying between wide ranging nomadic movements and also more directed seasonal migrations between summer and winter ranges. Saiga movements in the open and vast grasslands are driven by unpredictable, local precipitation events followed by vegetation green-up, often resulting insaiga shifting from directed movements to more wandering movements to track green up.

About 2 million Mongolian gazelles roam the grasslands of Mongolia and adjacent areas in Russia and China. The species’ most important stronghold is the steppe habitats east of the Trans-Mongolian Railway. These gazelles are true nomads, rarely settling in one place and showing no fidelity to seasonal ranges or movement corridors.

About 100,000 Asiatic wild ass or khulan still roam the drylands of Eurasia. The largest remaining interconnected population is found in the Mongolian Gobi, where an estimated 86,000 khulan – constituting over 80% of the global population – are found. In the Mongolian Gobi, khulan roam across thousands of kilometers and their movements are among the longest reported for terrestrial mammals both globally and nationally.
