Data
In 2024, a reliable European index was produced for 170 species, the same number as in the last update 2023.

A total of 30 countries provided their data for this update: Andorra, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Republic of Ireland, Romania, Slovenia, Slovakia, Spain, Sweden, Switzerland, United Kingdom.

The countries provided the data for different periods; see Methods, chapter 2.3, for types of supranational results that PECBMS produces, or check the List of countries in individual species graphs.

Methods
A detailed description of computation steps and methods is available in the section Methods, Chapter 1. National species indices and trends and Chapter 2. Supranational species indices and trends.

Species habitat classification for main habitat types (farmland, forest, and other) is described in Methods, chapter 3, Box Species Selection and Classification.

Results
In the table, we present long-term and ten-year trends and slopes. The Long-term Slope is calculated over the period 1980–2023, but the starting years of this long period vary from 1980 to 2006 (check the pop-up windows after clicking on the numbers shown in selected species names as an upper index). In parallel, the Long-term Trend represents a change (in %) in an index value between the first and the last year of this long period. The Ten-year Slope is calculated over the previous ten years, i.e. 2014–2023. Similarly, a Ten-year Trend represents a change (in %) in an index value between the first and the last year of the period of the previous ten years.

The table summarises the updated European species indices, long-term and ten-year trends and slopes, and the species habitat classification. To view the table explanation, click the superscript letters in the header to open a pop-up window.

To generate a graph for the selected species, tick the checkbox at the left side of the species name and click the Show button above the table to confirm and proceed with your selection. You can draw graphs for several selected species in separate graphs or at once in one graph – choose the option from All data in one graph above the table. If you wish to show confidential limits, you may choose this option only if you select only one species to be displayed in a graph. You can also quickly deselect your choice (Reset). The countries and periods for which the countries provided the data can be found in individual species graphs (Countries). You can order species trends by alphabet or taxonomic classification, see the Order button at the head of the table, and select alphabet or taxonomy.
