Which one of the following protected areas is well-known for the conservation of a sub-species of the Indian swamp deer (Barasingha) that thrives well on hard ground and is exclusively graminivorous?

• (a) Kanha National Park: Correct. Kanha is famous for conserving the hard-ground barasingha (Rucervus duvaucelii branderi), a sub-species of swamp deer adapted to firm ground and known to be exclusively graminivorous.
• (b) Manas National Park: Incorrect. Manas is important for species like pygmy hog, golden langur and wild buffalo, but it is not the noted site for hard-ground barasingha conservation.
• (c) Mudumalai Wildlife Sanctuary: Incorrect. Mudumalai is known for elephants, tigers and gaur, not for the hard-ground sub-species of barasingha.
• (d) Tal Chhapar Wildlife Sanctuary: Incorrect. Tal Chhapar is chiefly known for blackbuck conservation, not barasingha.

Answer: (a) Kanha National Park.
