India’s Bat Conservation Assessment: Species, Threats, Roles
Why in the news
A nationwide assessment prepared by wildlife biologists together with the Environment Ministry warned that bats face rising pressure while scientific data remain thin.
Key findings
| Theme | Finding |
|---|---|
| Species count | 135 species, roughly 10% of global bat diversity |
| Risk status | Nearly 25% Threatened or Near Threatened (local parameters) |
| Data gap | Over 40% Data Deficient; some may be declining unnoticed |
Main threats
- Habitat loss and fragmentation: urbanisation and deforestation destroy roosts such as old-growth trees and forests.
- Cave disturbance: mining, quarrying and cave tourism push insect-eating bats out of subterranean roosts.
- Climate change: heatwaves cause mass die-offs of fruit bats (Flying Foxes), which are sensitive to temperatures beyond 45°C.
Why bats matter
- Pest control: insectivorous bats eat crop pests such as moths and beetles, saving agriculture billions of rupees yearly.
- Pollination: big fruit bats pollinate economically useful plants including durian, wild bananas and agave.
- Seed dispersal: they drive forest regeneration by carrying seeds over distances birds cannot cover.
Exam angle
- Numbers: 135 species, 25% at risk, 40%+ data deficient, 45°C heat threshold.
- Ecological role label: “ecological linchpins”.
- Term: Data Deficient means too little information to assess conservation status.
