Welcome to Denmark BMS
In this tab, you will find specific information about the Danish butterfly monitoring scheme – colloquially Denmark's Daybutterflies. Please note that this butterfly monitoring scheme has its own official website, where you can find additional information.
About the Danish BMS
The Danish butterfly monitoring network began operating in 2023, and currently collects transect count, 15-minute count and moth trap data through the eBMS website and ButterflyCount App. This BMS is led by Aarhus University and is supported by Naturrådgiverne Eskildsen & Buur. It continues to grow thanks to the efforts of the national coordinator, Anne Eskildsen, and the financial support of AAGE V JENSENS NATURFOND and 15. Juni Fonden.
