Temporal trends of land-use favourability for the strongly declining little bustard: assessing the role of protected areas Open
The little bustard ( Tetrax tetrax ) is a steppe bird strongly and negatively influenced by agricultural intensification in Europe. Here, we use the little bustard as a model species to examine how favourability (relative occurrence likeli…
