Kanha National Park is well-known for the conservation of the hard ground Barasingha.
The Barasingha (*Rucervus duvaucelii*) has three subspecies: the swamp-dwelling form (*duvaucelii*) found in the Terai and Assam, and the hard ground form (*branderi*) found in Central India. Kanha National Park in Madhya Pradesh is the primary habitat and the main conservation success story for the hard ground Barasingha, which faced near extinction before recovery efforts in the park. This subspecies is known for its preference for hard ground and its graminivorous diet.
The conservation of the hard ground Barasingha at Kanha National Park is considered a significant achievement in wildlife management in India. Manas National Park is known for the swamp deer subspecies, but not the hard ground variety.
