We are deeply grateful to Arco van Strien, Adriaan Gmelig Meyling, Thomas van der Meij, and Marnix P. de Zeeuw (all from the Statistics Netherlands). They developed tools for calculating indices and trends and provided essential support with the computation procedures. We greatly appreciate their valuable assistance in implementing the new tools and adapting them to the needs of PECBMS.
We thank the members of the PECBMS Steering and Technical Group – Richard Gregory (the Royal Society for the Protection of Birds), Sergi Herrando (the Catalan Ornithological Institute), David Noble (the British Trust for Ornithology), Anna Staneva (the BirdLife International), and Zdeněk Vermouzek (the Czech Society for Ornithology) – for their valuable comments and their assistance with data collation and analysis.
We also extend our thanks to our key partner organisations.
The Pan-European Common Bird Monitoring Scheme is a joint initiative of the European Bird Census Council (EBCC) and BirdLife International. Since its launch in 2002, the PECBMS project has been supported by the Royal Society for the Protection of Birds (RSPB, the BirdLife International Partner in the UK).
Since January 2006, the project has received financial support from the European Commission.
Other important partners of the project include Statistics Netherlands (CBS), the Czech Society for Ornithology (CSO, the BirdLife Partner in Czechia), the British Trust for Ornithology (BTO), the Dutch Centre for Field Ornithology (SOVON), the Catalan Ornithological Institute (ICO), and others.
