- Technical Report EU Butterfly Grassland Species 1990 - 2017

We are pleased to inform you that we have updated the EU Butterfly Indicator for Grassland species, 1990-2017. We produced a technical report to describe the indicator, it represents a major update on previous versions, through the incorporation of more and expanded datasets, together with new analysis techniques. It is the first major output of the Assessing ButterfLies in Europe (ABLE) project. This would not have been possible without the effort of all the collaborators, national schemes and volunteers that provide the data. Our appreciation to all of them.

The EU Butterfly Grassland Species 1990-2017 indicator is part of the monitoring report on progress towards the SDGs in an EU context — 2019 edition, which can be accessed here.  The grassland butterfly indicator contributes to Goal 15: Life on Land.
