European wild bird indicators, 2015 update

Pan-European Common Bird Monitoring Scheme (PECBMS) presents a set of updated European wild bird indicators for the time period 1980-2013. The indicators are computed for Europe and its regions (West, North, Central & East and South Europe), and EU, New and Old EU states for common farmland, common forest, and all common birds. Both single European and BioGeo regional species habitat classification are used to assess if each bird species belongs to farmland, forest or other indicator.

Data

The individual species indices that are used for computation of European indicators were produced for 169 European common birds. For computation of regional indicators for West, North, Central & East, and South Europe or for EU, New and Old EU states, the regional and EU individual species indices are used, respectively. Two species (Oenanthe cypriaca and Sylvia melanothorax) haven´t been included in all common bird indicators for Europe and EU as they are endemic species for Cyprus and not common for whole Europe (so only 167 species included in all common bird indicators). Number of species included in common farmland bird indicators for Europe and EU remained unchanged (39 species) while a new species (Serinus citrinella) was added on the list of species in common forest bird indicators for Europe, EU and regional indicators (34 forest species).

Methods

The computation procedure of the individual species indices is described in the Methods section, chapter 1. National species indices and trends (computation of national species indices) and chapter 2. Supranational species indices and trends (computation of supranational - European and regional - species indices).

Indicators (multi-species indices) are computed as a geometric mean of the set of individual (either European, EU or regional) species indices with the application of the method of chain index in case the species indices are provided for a time period of a different lenght. Detailed description of the computation procedure is described in the Methods section, chapter 3. Multispecies indicators.

Species habitat classification
Species habitat classification for main habitat types (farmland, forest and other) has been developed using improved procedure accepted at the PEBCMS workshop in Prague in 2005. We used two version of species habitat classification - single European and BioGeo regional species habitat classification. Detailed information including the list of species with their habitat classification is provided in the Methods section, chapter 3, Box Species selection and classification.

Results

In the tables below, you can find the set of main European, EU and regional indicators produced in 2015.
For the complete information on an indicator (graph, list of species and list of countries), click the indicator name in the Indicator column.
For the list of species only, click the number in the No. of species column.
For the list of countries only, click the name of region in the Region column.
For drawing and comparing graphs for several indicators at once, tick the check boxes at left side of indicator names and press ENTER or click Show graphs for selected indicators button below the table to confirm and proceed your selection. You can also draw graphs for all indicators at once (Select all) or quickly deselect your choice (Reset).

At each presentation of indicator´s graph, click the List of species and their trends for showing the list of species and their trends since the year indicated in the Base year column. For the list of countries, click the List of countries.
Below the indicator graph, the numbers of species in each indicator which are declining (moderately or steeply declining), increasing (moderately or strongly increasing), stable and uncertain are presented.

For comparison, check the previous version of indicators produced for the time period 1980-2012.
