Fauna and Flora
The vegetation of the Ordos region is made up of montane grasslands and shrublands. Among the sand dunes in the north, shrubs including Hedysarum scoparium and Calligonum arborescens grow in scattered patches. Native grasses and herbs include Bromus inermis, Agropyron mongolicum, A. cristatum, Festuca arundinacea, Elymus dahuricus, Melilotus albus, M. officinalis, Lotus corniculatus, Pugionium cornutum, Astragalus adsurgens, and Filifolium sibiricum. The belt of sand and clay which separates the sand dunes from the Huang He in places is studded with little mounds (up to 1.2 m high), mostly overgrown with wormwood (Artemisia campestris) and the Siberian pea-tree (Caragana spp.); and here too grows one of the most characteristic plants of Ordos, the liquorice root (Glycyrrhiza uralensis). On the left bank of the Huang He, level spaces amongst the dry river beds are studded with little mounds (9 cm to 1.8 m high), on which grow stunted Nitraria schoberi and Zygophyllum. Towards the south, sparse scrub vegetation is found. Forest thickets thrive along the river margins.
In the Yin Mountains, forests begin at altitudes of 1,600 m and wild flowers grow in great profusion and variety in summer, though with a striking lack of color. In this same border range there is also a much greater abundance and variety of animal life, especially among the birds.
Rare bird species also breed in the saline lakes of the Ordos, among them Relict Gulls (Larus relictus), for this species the Ordos is home to about one quarter of the world's population.
The present status of large mammals in the region is largely unclear. In the past, it was inhabited by wild two-humped Bactrian camels, snow leopards, Przewalski's gazelles, and Przewalski's horses. It has been observed that Asiatic wild asses have been leaving the region for less populated areas on the Mongolian border.

Famous quotes containing the words fauna and/or flora:
“The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.”
—Louis Aragon (1897–1982)
“A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”
—Henry David Thoreau (1817–1862)
