Raptors have attracted great interest due to the strong population declines suffered over the 20th century in Europe. In the Mediterranean basin, however, forest species have often been poorly monitored so far. The lack of a standardized monitoring methodology for this group of species poses problems in official communications on the state of populations, such as the Article 12 reporting of the Birds Directive and the reporting of the species status in Natura 2000 sites by EU member states. In Catalonia (NE Spain), in contrast to scarce cliff-nesting raptors, data on forest raptors have been collected using a variety of different methods and have remained largely decentralized up until now. After a series of discussions, a new standardized long-term monitoring scheme—the SEGRE project (general raptor monitoring in specially protected areas, in Catalan: SEguiment General de Rapinyaires en Espais naturals protegits)—was launched in 2019, based on previous experiences from both Catalonia and other European countries. The project coordinates the collection of precise information on territories of raptors in protected areas. SEGRE aims to accurately inform on the status and trends of forest raptors and represents a basis for the assessment of the impact of management, particularly within each protected area. Its protocol consists of four 3-hour morning surveys from a fixed viewpoint with good visibility within a reference 2.5× 2.5 km square grid. The visits cover the whole breeding season of a target species between March and July. Each observation is geo-located together with a behavioural code that facilitates determining the breeding status, to …
