In March we have produced new leaflet presenting the trends of 170 common European bird species based on data from 28 countries covering 37 years (1980–2016). The leaflet summarises outputs of this 2018 data update and presents a nice example of use of bird monitoring and atlasing in species conservation. PECBMS and EBBA2 data on the European Turtle-dove helped to identify Prioroty Intervention Areas for this species.
You may download the pdf version of the leaflet.
Of the 170 species covered, in long-term 52 increased moderately, 65 declined moderately and one steeply, while 46 remained stable. In six cases the species´trends remained uncertain.
Of the 170 species, only 168 are included in the common bird indicators for Europe and EU. The Cyprus wheatear (Oenanthe cypriaca) and Cyprus warbler (Sylvia melanothorax) have been excluded as they are endemic species for Cyprus.
All common species (168 sp.) declined by 15 % since 1980, common forest birds (34 sp.) declined by 6 % and the worst decline continued in common farmland birds (39 sp.), of which we have lost 57 % since 1980.
European wild bird indicators. The numbers in italics show the numbers of species in each indicator which are moderately or steeply declining, moderately or strongly increasing, stable and ucertain.
Bird monitoring and atlasing is helpful in the identification of threats and also in steering conservation actions: using the data collected for the Second European Breeding Bird Atlas (EBBA2), experts modelled probability of European Turtle-dove occurrence in Europe on 10×10 km grid. The map was then used to identify Priority Intervention Areas (PIAs) (Herrando et al. 2018), which indicate where conservation interventions might be best directed.

If you wish, ask for the printed version of the leaflet via e-mail: firstname.lastname@example.org. We apologize for a mistake in the printed version of the leaflet. In the legend for the graph of wild bird indicators there are the colours for the common species and farmland species confused. All common birds should be in blue and farmland birds should be in red. We are very sorry for this inconvenience! The pdf for download is corrected.
