We are very grateful to Arco van Strien, Adriaan Gmelig Meyling, Thomas van der Meij, and Marnix P. de Zeeuw (all from Statistics Netherlands). They developed a tool for calculating indices and trends and assisted with a computation procedure. We appreciate their valuable help with the new tools’ implementation and their modifications for PECBMS needs.

We thank members of the PECBMS Steering and Technical Group – Richard Gregory (RSPB), Chris van Turnhout (SOVON), David Noble (British Trust for Ornithology), Anna Staneva (Birdlife International), and Zdeněk Vermouzek (Czech Society for Ornithology) – for valuable comments and help with data collation and analysis.

Pan-European Common Bird Monitoring Scheme is a joint initiative of the European Bird Census Council (EBCC) and BirdLife International.

Since January 2006, the project has been funded by the European Commission.

Other important partners of the project are Statistics Netherlands, Czech Society for Ornithology (CSO, BirdLife Partner in the Czechia), British Trust for Ornithology (BTO), Sovon Dutch Centre for Field Ornithology (SOVON), L’Institut Català d’Ornitologia (ICO), and others.
