The Dwarf Blue Sheep or Dwarf Bharal Pseudois schaeferi is an endangered species of caprid found in China and Tibet. It inhabits low, arid, grassy slopes of the upper Yangtze gorge in Batang County of the Sichuan Province, and a small part of the Tibetan Autonomous Region, where it is known by the local name Rong-na. The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. ...

Originally given subspecific status to the Bharal (Pseudois nauyar), morphological research conducted in the 1970s led it to be considered a distinct species. However recent molecular analysis has shown the difference between the two species is slight, and suggests it should be treated as a subspecies of the Bharal. In zoology, as in other branches of biology, subspecies is the rank immediately subordinate to a species. ...

The Dwarf Blue Sheep differs from the Bharal primarily in size, with adult males weighing around 35kg, half as much as the Bharal. Less sexual dimorphism occurs in this species, and females of the two species are very similar. Its coat is a steely grey with a silvery sheen, with darker general colouration than the Bharal, and the horns of the male are smaller, thinner and more upright, with no inward curl. Female (left) and male Common Pheasant, illustrating the dramatic difference in both color and size between the sexes Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species. ...

In 2000 there were estimated just 200 individuals of Dwarf Blue Sheep alive. The species is hunted, and in their limited range cannot escape from humans and livestock. Although a reserve of 142.4 square km was set up around Zhubalong in 1995, human activities continue to go on there. Sheep are commonly bred as livestock. ...
