Forests and Wildlife of Bihar – Biodiversity, National Parks and Conservation

Explore the forests and wildlife of Bihar, including major forest types, national parks, wildlife sanctuaries, biodiversity and conservation efforts.

Forests and Wildlife of Bihar

Bihar is widely known for its rich history, fertile plains, and cultural heritage, but the state is also home to diverse forests and valuable wildlife. Although forests cover only a small percentage of Bihar’s total geographical area, they play an essential role in maintaining ecological balance, conserving biodiversity, preventing soil erosion, and supporting local livelihoods. Bihar’s forests provide habitat for many species of mammals, birds, reptiles, and plants, making them an important natural resource.

The forests of Bihar are mainly concentrated in the northern foothills near Nepal and the southern districts adjoining the Chotanagpur Plateau. These forests include tropical moist deciduous forests, tropical dry deciduous forests, riverine vegetation, and grasslands. The state government and environmental organizations continue to work towards protecting wildlife through national parks, wildlife sanctuaries, afforestation, and conservation projects.
