Wildlife of
Jhārkhand

Primary Threats

• Jharkhand's mineral-rich plateau (coal, iron ore, bauxite, mica) drives large-scale open-cast mining and associated waste dumps, which directly clear sal forests, fragment elephant and carnivore movement routes, increase night traffic and human presence, and degrade streams through siltation and acid/metal-laden runoff in mining-affected catchments (notably in coalfields and iron-ore belts).
• Forest conversion and degradation occur through settlement expansion, encroachment at forest edges, small-scale quarrying, and repeated disturbance in sal/dry deciduous systems. Loss of contiguous canopy and understory reduces secure habitat for elephants, ungulates and ground-nesting birds and increases human access for extraction.
• Road widening, railway lines, power transmission corridors and industrial corridors dissect forest blocks in the Palamau and Singhbhum-Dalma landscapes. Linear infrastructure increases mortality risk (vehicle/train strikes), enables further encroachment, and disrupts traditional elephant movement routes, intensifying conflict in bottleneck corridors.
• Elephant movement between forest patches and crop fields leads to recurring crop loss, house damage and occasional human fatalities, particularly where corridors have narrowed in the Singhbhum-Dalma belt and around fragmented forest-agriculture mosaics. Leopard conflict and retaliatory killing can occur near villages where prey depletion pushes carnivores toward livestock.
• While commercial felling is regulated, illegal timber removal and chronic extraction of poles/fuelwood persist around accessible forest edges. Degradation is often subtle but cumulative-reducing sal regeneration, opening the canopy, and increasing fire susceptibility.
• High dependence on non-timber forest products (fuelwood, fodder, tendu leaves, mahua, medicinal plants) can become unsustainable near densely populated fringes and mining/industrial townships, lowering food availability for wildlife and eroding forest structure.
• Industrial emissions and effluents (thermal power, steel and ancillary industries) and mine drainage contribute to air and water pollution. River and reservoir systems receive sediment and contaminants, affecting aquatic biodiversity and downstream drinking-water quality; fly ash and particulate deposition also stress adjacent vegetation.
• Incremental expansion of agriculture into forest fringes and shifting land use around plateau villages reduces buffer habitat and increases conflict. Intensive cropping near corridors attracts elephants during harvest seasons, reinforcing repeated conflict cycles.
• Altered fire regimes (frequent dry-season burning), small dams/check-dams, and stream-channel modifications change forest and riparian dynamics. Repeated fires suppress regeneration in sal forests, promote fire-tolerant grasses/invasives, and simplify habitat structure.
• In disturbed sal and scrub patches, invasive plants (notably Lantana camara in many dry deciduous landscapes) can form dense thickets that hinder native regeneration, alter forage availability, and complicate habitat management and patrolling.
• Opportunistic hunting for bushmeat and local retaliation killings (especially after conflict incidents) persist in some areas. Even low-intensity offtake can depress prey populations needed by large carnivores and increase human-wildlife antagonism.
• Jharkhand's connectivity to regional trade routes creates risk for illicit trade in pangolin scales, leopard parts and other wildlife products. Trade pressure compounds local hunting and undermines recovery of already slow-breeding species.
• High daily human use of forests (grazing, fuelwood, NTFP collection), coupled with mining-linked settlements and traffic, increases noise/light disturbance, reduces daytime wildlife activity, and elevates poaching risk in easily accessible compartments.
• Hotter summers and more erratic monsoon patterns can intensify drought stress in dry deciduous forests, increase fire frequency, and reduce water availability in seasonal streams and small reservoirs-pushing elephants and other wildlife toward irrigated fields and village water sources.
• Close interface among wildlife, livestock and free-ranging dogs near villages raises risks of disease spillover (e.g., canine-borne diseases affecting carnivores) and livestock illness that can trigger grazing pressure shifts deeper into forests.
• Growth of urban-industrial nodes around mining and manufacturing hubs expands built-up areas and peri-urban sprawl, increasing demand for land, water, and construction materials and adding chronic disturbance along forest peripheries.
• Fragmentation of elephant and carnivore habitat into smaller, more isolated patches can reduce functional connectivity over time, risking reduced gene flow for wide-ranging species where corridors are narrowed by mines, roads and settlements.
• In rivers and reservoirs, intensive fishing pressure and destructive practices in some stretches can reduce fish biomass and alter aquatic food webs, indirectly affecting riparian biodiversity and species such as otters and river-dependent birds.
