Justification of Red List category
This species has suffered rapid population reductions across most of its range owing to the loss, degradation and fragmentation of its habitat due to agricultural intensification and industrial expansion (including energy development), with climate change exacerbating these effects through increased frequency of extreme weather events and wildfires. In addition, illegal killing, elevated predation rates and disturbance are contributing to declines, with increased access to and division of the species' habitats by expanded and upgraded road networks compounding these threats. Population declines are currently estimated to be rapid, but are projected to become very rapid in the near future and over the next three generations. Accordingly Great Bustard is assessed as Endangered.
