The world Great Bustard population can be estimated at present around 44100-57000 birds. The Iberian Peninsula, with c.a 60-70% of the world population, probably represents the last stronghold of the species in the world. All other populations surviving at present are much smaller, many have suffered dramatic decreases, and some are now threatened with extinction. The species is considered globally threatened, and in Spain it was classified as vulnerable until 2011. This means that the survival of Spanish populations might be endangered by human-induced changes in the habitat, catastrophic events, or any other causes which might affect their population dynamics.
