This European Butterfly Monitoring (eBMS) App enables you to contribute to butterfly conservation by providing important information on where different species occur and the numbers found in different places across Europe. Contribute your counts of butterfly species alongside accurate location information, added via a dynamic map or via GPS acquired route information. You can add photos to support your observations. This free resource makes it easy to keep track of what you see, while making your data openly available for scientific research, education and conservation.
