Koderma Wildlife Sanctuary

Overview: The Northern Scarp Frontier

Spanning 150.62 square kilometers across the rugged northern edge of the Chota Nagpur Plateau along the border of Jharkhand with Nawada and Gaya districts of Bihar, Koderma Wildlife Sanctuary is a dramatic landscape of quartzite ridges, deeply incised gorges, and dry deciduous forests.

Established in 1985 under the Wildlife (Protection) Act of 1972, the sanctuary protects the crucial watershed of the **Sakri River** and its tributaries (Poanchkhara and Telaiya streams). Historically situated within the famous mica-mining belt of Jharkhand (once renowned globally as the "Mica Capital of the World"), the establishment of the sanctuary successfully transitioned large swathes of fragile forest hills from commercial extraction into strict wildlife conservation.

Bordered to the south by the expansive **Tilaiya Dam reservoir** and punctuated by sacred granite monoliths like **Dhwajadhari Hill**, Koderma shelters thriving populations of **Indian Leopards** (Panthera pardus), **Sloth Bears**, **Striped Hyenas**, **Sambars**, and the rare **Four-horned Antelope** (Tetracerus quadricornis).

Geology, Mica Ridges & Watershed Stratification

The sanctuary's terrain features a dramatic altitudinal drop from the high plateau down to the Gangetic alluvial plains:

The rich mineral composition of the pegmatite rocks provides natural mineral licks that attract ungulate herds during late afternoons. In recent years, the Forest Department has constructed stone-masonry check-dams and silt-detention bunds across the seasonal Poanchkhara ravines, maintaining pools of fresh drinking water well into the scorching pre-monsoon summer months of April and May.

Wildlife Profile & Nocturnal Carnivores

Koderma's rocky crevices, caves, and dense Sal ravines provide ideal denning sites for nocturnal predators:

Birdlife includes the **Shaheen Falcon**, **Crested Serpent Eagle**, **Jungle Nightjar**, **Sirkeer Malkoha**, and **Indian Grey Hornbill**.

Cultural Heritage: Dhwajadhari Hill & Sacred Monoliths

Rising prominently near Koderma town is the sacred granite peak of **Dhwajadhari Pahar** (Lord Shiva Temple). Reached by climbing over 700 stone stairs carved into the mountainside, the summit offers breathtaking panoramic views across the forested scarp and Jhumri Telaiya valley.

During *Maha Shivaratri*, the hill is illuminated by thousands of pilgrims. Forest Department checkpoints ensure that pilgrimage routes remain clean, plastic-free, and respectful of the surrounding wildlife habitat.

Local indigenous Birhor and Santhal forest fringe communities, who previously depended on hazardous collection of mica scrap (*Dhibra*), are now actively integrated into Joint Forest Management (JFM) committees as eco-watchers and forest guides, promoting sustainable forest produce harvesting of tendu leaves, mahua seeds, and wild medicinal roots.

These forest protection groups actively patrol the rocky ravines during summer to prevent forest fires and safeguard perennial wildlife watering holes from illegal poaching traps.
