Jharkhand has a rich variety of flora and fauna. The National Parks and the Zoological Gardens located in the state of Jharkhand present a panorama of this variety.

Betla National Park (Palamu), 25 km from Daltonganj covers an area of about 250 square kilometres. The national park has a large variety of wild life like tigers, elephants, bisons locally called gaurs, sambhars, hundreds of wild boar and 15 to 20 feet long python, herds of spotted deer (cheetals), rabbits and foxes. The mammalian fauna to be seen at Betla National Park also include langurs, rhesus, blue bull and wild boars. The lesser mammals are the porcupine, hare, wild cats, honey badgers, jackals, Malabar giant squirrel, mongoose, wolf, antelope, etc. In 1974, the park was declared Project Tiger Reserve.

Part of the reason for the variety and diversity of flora and fauna found in Jharkhand state may be accredited to the Project Tiger Reserve of Palamu, which is abode to hundreds of species of flora and fauna, as indicated within brackets: mammal (39), Snakes (8), Lizards (4), Fish (6), Insects (21), Birds (170), seed bearing Plants and Tress (97) , Shrubs and Herbs (46), Climbers, Parasites and semi-Parasites (25), and Grasses and Bamboo (17).

The Hazaribagh Wildlife Sanctuary, with scenic beauties, 135 km from Ranchi, is set in an ecosystem very similar to Betla National Park of Palamu.

One Zoological Garden is also located about 16 km from Ranchi, and a number of mammalian fauna have been collected there for visitors.
