‘Crucial opportunity to act’ as study finds most of Europe’s wild bee species in decline

As Cop17 kicks off, records since 1921 show more bee species declining than increasing in all parts of Europe except the Alps

Most of Europe’s wild bee species and about half of its hover fly species have declined over the last century, a study has found, as a UN biodiversity summit begins in Armenia.

Records since 1921 show more bee species are declining than increasing in all parts of Europe except the Alpine region. The richness of bee and hover fly species suffered a persistent drop in the Atlantic and Continental regions, the study found, though trends in other regions were mixed or even positive.
