Study finds most Europe's wild bee species declining over past century
The Guardian reports that a study of European pollinator records since 1921 found most wild bee species have declined over the past century.
The short version
- The Guardian reports that most of Europe's wild bee species and about half of its hover fly species have declined over the last century.[The Guardian]
- Records since 1921 show more bee species are declining than increasing in every part of Europe except the Alpine region.[The Guardian]
- Bee and hover fly species richness dropped persistently in the Atlantic and Continental regions, according to the study covering 88% of species.[The Guardian]
- Lead author Carlos Martínez-Núñez said biodiversity loss could remain hidden behind apparently stable species numbers, which he described as a crucial opportunity to act.[The Guardian]
Key facts
- The study covers 88% of bee and hover fly species across the continent.[The Guardian]
- Ninety-one percent of species logged over the last century were also recorded at least once between 2001 and 2020.[The Guardian]
- Nearly 90% of wild flowering plants and more than three-quarters of major food crop types depend in part on animal pollination.[The Guardian]
- Species richness for bees and hover flies dropped persistently in the Atlantic and Continental regions.[The Guardian]
What remains uncertain
- The estimate that as many as 9% of species could have been wiped out is unconfirmed; researchers say many unseen species occur rarely in the historical record.[The Guardian]
