In western Europe, an estimated 70% of breeding pairs nest in agricultural farmlands, especially cereal crops. This makes the Montagu's harrier a very vulnerable species, and very dependent on nest protection. Bird protection non-governmental organizations participate in their protection, in collaboration with concerned landowners. Once a nest is spotted in a field, it can be safeguarded either by relocating it to a safer area or by creating a protected space which will not be harvested. In France and in the Iberian Peninsula, an average 60% of nestlings are saved by this kind of measures.
