Motivation

In the ABLE project new tools have been developed to make it easier for regional and national coordinators of Butterfly Monitoring Schemes to calculate indexes and trends as well as build indicators. This workshop will focus on the background of the method and learning how to use the tools. This workshop is open by invitation only to all co-ordinators of European Butterfly Monitoring Schemes as well as other people actively involved in the analysis and assessment of butterfly monitoring.
