Great Bustard Population Decline: Habitat Loss, Climate Change, and Human Threats

The great bustard (Otis tarda)—one of the heaviest flying birds—faces population declines across Europe and Asia.

Primary Threats

• Habitat loss/degradation: Conversion of steppes/grasslands to intensive agriculture, afforestation, infrastructure.
• Climate change: Altered precipitation, temperature extremes affect breeding success and food availability.
• Collisions: Power lines, wind turbines, fences.
• Hunting/poaching: Despite legal protection.
• Disturbance: Tourism, farming during nesting.
• Pesticides: Reduce insect prey for chicks.

Conservation Status

• IUCN: Vulnerable (global), Endangered in several European countries.
• CMS Appendix I/II; EU Birds Directive Annex I.

Conservation Actions

• Habitat restoration/protection (agri-environment schemes)
• Power line marking/undergrounding
• Predator management
• Reintroduction programs (UK, Germany)
• International cooperation (Central Asian flyway)
