European Butterfly Monitoring Scheme
The European Butterfly Monitoring Scheme (eBMS) is a collation of national Butterfly Monitoring Schemes datasets on behalf of Butterfly Conservation Europe.
eBMS is managed by the Natural Environment Research Council (acting through the UK Centre for Ecology & Hydrology, UKCEH) in order to facilitate research using the dataset and to promote the conservation of butterflies.
Partners
The eBMS includes several partners that provide their data every year from the different National Butterfly Monitoring Schemes throughout Europe. Currently, there are 21 formal partners in 19 different countries with their respective BMS. Click on the countries to see their National BMS websites and discover more about their butterfly monitoring, how to join and contact them.
Current partners (in addition to BCE and UKCEH) in the eBMS are:
2. Belgium (Flanders)
3. Croatia
5. Finland
6. France
7. Germany
8. Hungary

Partner meetings
eBMS and Butterfly Conservation Europe try to arrange an annual meeting with partners, experts, coordinators and people working and interested in butterfly monitoring. Physical meetings are arranged in Laufen every two years and you can check more information at the BCE website. You can find information below on the other meetings held online:

Become a new partner:
We will be delighted for more new partners in areas where is lack a Butterfly Monitoring Scheme. If you would like to become a new partner of eBMS and you are willing to collaborate and join eBMS, please contact ebms@ceh.ac.uk.
Collaborators
Apart from the eBMS partners, there are more countries and regions monitoring butterflies in Europe. Countries that are not partners of eBMS, without scheme or just outside of the European Union with different monitoring programs. These collaborators provide data to eBMS in order to contribute to the Butterfly Indicators or other types of results.
