Koderma is blessed with well-endowed natural resources. Though illegal mining and deforestation has taken its toll now, at one point of time, Koderma was 'the mica capital of India'. And it was during those heydays that the townships of Koderma and Jhumeri Tilaiya rose to become prominent places contributing their might to the economic well being of the Chotanagpur region.
Nestled deep within the picturesque Chotanagpur plateau Koderma commands a beauty of its own. Its rugged topography, hilly ranges, hillocks and mounds form part of the beauteous landscapes that attracts visitors from far off places. Koderma district and city share the same name.

Some endangered species of animals such as tigers, Asian elephants, Four-horned Antelope (Tetracerus quadricornis), blackbuck (Antilope cervicapra), and chinkara (Gazella bennettii), dhole wild dog (Cuon alpinus) and sloth bear (Melursus ursinus) are some of the wild species that are found here while rare birds like Lesser Florican (Eupodotis indica), Indian Grey Hornbill and other hornbills too are found in these forests.
It is saddening to note that much of the land in the forested region has been cleared for grazing and the scale of mining in the area has increased. This has resulted in lesser forest space in the habitat of these wild animals.
