Welcome to the European BMS Transect Walker online

Set up a new transect

We are glad to have you involved in this interesting project and we totally welcome new transects. These data will help us to calculate population trends and determine the status of different butterflies species. Therefore, conservation actions and management directed to butterflies will be more effective as more data as possible we collect.
