【 摘 要 】

This project set out to support the Streamlining European Biodiversity Indicators (SEBI) process by developing a prototype indicator of European bat population trends. The methodology for the construction of the indicator was built by adapting and testing a statistical approach previously developed for birds and butterflies. The resulting prototype hibernating bat indicator covered the period from 1993 to 2011; data were incorporated on 16 species from 10 schemes spread over 9 countries.
