Butterfly Monitoring Schemes
Butterflies are among the best-monitored insect groups thanks to long-term monitoring schemes that have run for decades in some countries. The first Butterfly Monitoring Scheme (BMS) began in the United Kingdom in 1976 (UKBMS), and since then, this methodology has been adopted in many other countries to monitor butterflies. All use the same standardised survey method, designed by Ernie Pollard, of the Monks Wood Experimental Station in the UK (Pollard and Yates, 1983). This vital information is gathered mainly by citizen scientists (volunteers) who have been trained (or are self-taught) to recognise and identify species and to follow monitoring protocols along butterfly transects.
The European Butterfly Monitoring Scheme, or eBMS, as its name indicates, was born as a network composed of national butterfly monitoring schemes from European countries. However, in recent years, eBMS has expanded to include BMSs worldwide, welcoming monitoring schemes from Asia, the Americas, Africa, and Oceania.
The eBMS network currently comprises 50 monitoring schemes distributed across 44 countries and territories worldwide.
In the list below, clicking on each country/territory will redirect you to its dedicated information hub. There, you will find specific contact information, support materials such as local field guides, and more. Some BMSs have different data collection protocols and support materials for citizen scientists, so please check the information provided by your BMS before participating. To request data from the eBMS database, please go to the eBMS data access policy page to read how to do this.
