Modelling the effectivity of a land sparing strategy to preserve an endangered steppe-land bird population in cereal farmland: scopes and limits

Agricultural intensification and the disappearance of fallow land have been identified as a major driver of biodiversity loss in European farmland. In particular, the dramatic population decline of the little bustard (Tetrax tetrax), a flagship bird species in western European cereal farmland, has b...
