Report on the Pan-European Common Bird Monitoring Scheme, June 2017

The report summarizes the activities of the Pan-European Common Bird Monitoring Scheme (PECBMS) between January and June 2017. Thanks to the new grant from the European Commission (project „New Generation European Wild Bird Indicators“), PECBMS core activities could re-start again in 2017. The project, led by RSPB in cooperation with CSO will deliver standard supra-national species trends and indicators and will make them available at the web site.

Use of outputs generated by Pan-European Common Bird Monitoring Scheme

Delivering the data which can be used for policy purposes as well as for research is the goal of the Pan-European Common Bird Monitoring Scheme. While by providing the data to policy and decision makers we aim the policies and decisions are based on scientifically sound evidence, by using the data for research purposes we aim to improve our understanding of bird population changes and their driving forces.

Here we bring an overview of use of PECBMS results for policy purposes, for public awareness and for a research as well. Despite the PECBMS keeps records of each use of the results, it is out of our control to keep records of all uses based on data extraction from the web site. Thus, the overview of the use of PECBMS results presented here is likely to be underestimated.

Use for policy purposes & public awareness

The multispecies population indices (indicators) produced by PECBMS have been the main outputs used for various policy purposes. Our European common bird indicators are included among the Streamlining European Biodiversity Indicators (SEBI), EU common bird indicators are part of the Indicators of Sustainable Development of the EU and European farmland bird indicator has been accepted as biodiversity indicator for EU´s Structural Indicator. National versions of the Farmland bird indicators have been also approved as the indicators for a Regulation in EU´s Rural Development Plans (Council Regulation (EC) No 1698/2005).

The indicators produced by PECBMS have been used by other international institutions too, Organisation for Economic Co-operation and Development (OECD), United Nations Environment Programme (UNEP), European Environment Agency (EEA) link, Secretariat of the Convention on Biological Diversity or European Court of Auditors among others. The indicators have been also included in Living Planet Index (LPI).

The graph below shows number of cases, when data were provided by PECBMS coordination unit for policy or public awareness purposes from 2005 to 2015. For example, in 2014 we provided the latest European Farmland bird indicator to the EEA for the fact sheet to IRENA indicators or to the BirdLife International for their press release on CAP reform, or European index for individual species for various papers or publications. Since many users extract data from the web site without informing the PECBMS coordination unit, the figures are probably underestimated. Last year PECBMS contributed latest EU indicators to the first European Red List of Birds, which was published in June 2015.

Development of bird indicators by PECBMS has also triggered development and use of such indicators at national level. Overview of the national indicators with links to national web sites can be found on http://www.bipindicators.net/wbi.

Use for research purposes

PECBMS seeks to analyse, interpret and publish its results in order to contribute to better understanding of population changes of birds in Europe. Papers resulting from PECBMS activities are usually led or co-authored by members of the wider team (Steering and Technical group, PECBMS coordination unit, EBCC Board), or the data have been used by other scientists who use the data publicly available.

Rules for using PECBMS data
PECBMS is happy to see the data have been used by external scientists for research purposes or for other publications, however we recommend always to contact the PECBMS coordination unit in advance in order to avoid misinterpretation of data presented on the web site. Moreover, we recommend to read the rules of using the PECBMS outputs which are stated in our Data Access And Co-authorship Policy.

For more information, contact project coordinator Petr Voříšek on EuroMonitoring@birdlife.cz.

New study: EU Nature policies reduce but don´t reverse decline of farmland birds

New research, published in Conservation Letters, by a team of conservation researchers, including BirdLife Europe and its partners [1], shows that EU nature legislation and EU agriculture-environment schemes can help to preserve farmland birds, however their impact is weakened by the devastating impact of agriculture intensification.

TRIM

TRIM (TRends and Indices for Monitoring data) is a program used to determine species’ population trends. It allows for missing counts using estimation, and yields yearly indices and standard errors using Poisson regression. TRIM is a freeware program developed by Statistics Netherlands in the framework of wildlife statistics.

New TRIM – TRIM in R

New version of the programme TRIM which was rebuilt as a package for the freely available and widely used open source statistical program R.

RTRIM contains the same methods and models for nature monitoring data as the original versions of TRIM. It can still work with the same input data and produces exactly the same output data, but as a package in R it can easily be integrated in other R programming processes. As a result of this there is a wider choice in how input data is provided, in how options and settings are chosen and how and what output is provided. New in this version is also the in-built possibility to combine results from other TRIM runs, e.g. to combine results obtained from the analysis of regions of a country into a single new output with a combined trend, indices and standard errors.

Being developed as R-package TRIM is as good as new and is made available for further developments by the large R-society. A development Statistics Netherlands is already working on, is making TRIM suitable for the use of multiple data per year (such as monthly counts). The renewed TRIM is available as RTRIM package on CRAN (Comprehensive R Archive Network).

Users of BirdStats cannot yet use this in combination with RTRIM, but we are working on a solution for that too.

Manual, documentation and helpfiles in the R environment with several programming examples can be found on the CRAN website. For any questions about the use of RTRIM, please contact rtrim@cbs.nl.

Also, RTRIM shell documents have been developed by Statistics Netherlands, which provides calculation and outputs of national species indices in a standardized way. Using this shell makes it easier to process large batches of species with specific model parameters at once. The shell is a combination of several R scripts together with a short user guide and can be downloaded here. Note that the use of covariates in the models is not yet included in this new development, but will be in the future.

See more info about TRIM also on the website of the Statistics Netherlands

Old TRIM – TRIM in Delphi

Old version of the programme TRIM was originally developed some 25 years ago by Statistics Netherlands (Pannekoek and Van Strien, 1991) and was made available as a freeware stand-alone program. The program has had several updates since then, however, the original programming language (Delphi) has become outdated and rendered further developments.

The latest version is TRIM 3.54 (released in 2006) which is designed to run under 32-bits versions of Windows, as Windows98, Windows2000 and WindowsXP.

Warranty Disclaimer. This software and the accompanying documentation is provided “as is”. Statistics Netherlands disclaims all warranties, either expressed or implied.

TRIM can be downloaded from the EBCC website together with a manual, a powerpoint presentation explaining TRIM for first users, and papers using the TRIM method. Alternatively, you can download TRIM as a part of the program BirdSTATs which enables to calculate indices and trends in batch mode to perform the statistical analysis for series of bird counts in the dataset.
