1. The European bird monitoring programmes as potential source of geo-referenced bird data Petr Voříšek Pan-European Common Bird Monitoring Scheme (PECBMS) & European Breeding Bird Atlas 2 (EBBA2), Czech Society for Ornithology/European Bird Census Council (EBCC)

2. Pan-European Common Bird Monitoring Scheme (PECBMS) Goal: to use common birds as indicators Source of data: national/regional monitoring schemes www.ebcc.info/pecbm.html 27 countries, 163 species in 2014 1km 500m Standardised methods Volunteer fieldworkers > 11 000

3. Species indices Main PECBMS output s Common bird indicators More on http:// www.ebcc.info/pecbm

4. Changes in absolute abundance and biomass Inger et al. 2015. Ecology Letters.

5. Regional indices

6. Use of PECBMS outputs for policy & promotion purposes PECBMS outputs used in 23 scientific peer-reviewed papers Common bird indicators included in 7 international sets of indicators accepted by governments as official indicator in at least 26 European countries

7. PECBMS network National Coordinators Volunteers Central Coordination Unit Statistics Netherlands Technical Group Steering Group raw data Expertise software coordination advice coordination advice national indices oversees the project management assists with technical statistical issues Annual Indices, Indicators & Reports

8. TRIM (= TRends & Indices for Monitoring data): analyses time series of count data from monitoring scheme with missing observations uses log-linear models and Poisson regression considers both site-effect and year-effect in the models allows to incorporate weights and covariates in the calculation calculates species yearly indices and trends (slopes) Calculation national & supranational indices

9. Production of European indices & indicators 1.TRIM output files from national coordinators 2.Data quality control at central coordination level 3.Production of European indices and indicators (PECBMS coordination team)

10. Contributing countries and their time series http://www.ebcc.info/index.php?ID=561#Box%20Participating%20countries

11. Always produced by TRIM and regularly used by PECBMS: OUT file – contains outputs of calculation, indices and trends OCV file – contains year-year covariances (needed only for calculation of European indices) Data files produced by TRIM

12. Optionally: S1 – contains slope parameters and indices for each year F1 – contrains estimated and imputed counts on site level Data files produced by TRIM So far, F1 files used only for special research studies and internal exploration of the usage of site-level data. Use of F1 files subject of approval by national coordinators.

14. F1 files in details: Sites at different spatial resolution depending on fieldmethods 1km 500m Large amount of data Inconsistencies in site codes F1 not available when data from more schemes within a country are combined Use of weights and covariates in models modifies the values in F1 Completeness of species asemblage info? Various coordination systems used Approval by national coordinators needed

15. European Breeding Bird Atlas (EBBA2) 2013-2017 Updated distribution maps for all European breeding birds at 50x50 km resolution: Breeding evidence Abundance Changes in distribution from 1980s to 2010s at 50x50 km resolution fine-grained distribution for as many bird species as possible and project them at a resolution of 10x10 km (model) This atlas will be one of the biggest biodiversity datasets across the world!!
