Worrying Surge in At-Risk Non-Managed Bee Types Across European Nations
The number of native bee types in European nations confronting dying out has more than doubled in the last ten years, while the number of threatened butterfly types has close to doubled.
This critical situation for crucial pollinators was revealed by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of over 1900 were threatened with extinction in the European continent.
The number of butterflies threatened with extinction in European nations has grown from thirty-seven to 65 since the previous assessment, conducted over a decade past. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their beauty and cultural significance, pollinators like bees and butterfly species are essential supports for our health, our food chains and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” said the IUCN director general. “The most recent European red list evaluations reveal major obstacles, with dangers growing for butterfly types and essential wild bee species.”
The factors of the quick recent decreases are the persistent harm or degradation of natural habitats caused by farming intensification and deserted farmland, draining wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Global warming is also revealed to be a significant danger: 52% of all threatened butterfly species in the European continent are threatened by the climate crisis – roughly double the number as a ten years ago.
As many as 90% of plants that flower in Europe rely on pollination by animals, according to the wild bee assessment’s lead coordinator. “Sadly, wild bee groups are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebees, which play a crucial role in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, recognized for pollinating trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the single type of this genus group in the European continent, is now assessed as severely threatened – the scientific classification nearest to extinction in the wild.
Butterflies that are only found on mountain tops are especially at risk to global warming as they need to move uphill as their living spaces become hotter but ultimately have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean, species such as the severely threatened Karpathos grayling butterfly are threatened by severe drought and wildfires.
At the same time, in the Arctic region, climate change is resulting in the tree line to shift northward by dozens of meters each year, with bushes taking over bog and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to feed on northern grasslands and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The greatest living space for all these pollinating species is grassland rich in flowers and that is disappearing very fast throughout the European continent because of all these reasons,” remarked Martin Warren. “The good news is that so many people are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are property owners who are engaged. We hope they can obtain the encouragements that will help them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of steps for pollinating insects which will not decrease agricultural output – and could improve it – such as farmers establishing margins rich in flowers around their fields.
the EU’s environment commissioner, described the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is necessary to confront this danger. Along with member countries, the European Commission has put in place an EU-wide tracking system for pollinating species based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to prioritize application and partnership with member countries to preserve our pollinating species,” she said.
The issuance of the bee and butterfly assessments comes after the first Europe-wide assessment of hoverflies, an additional essential pollinator group. Issued in 2022, it revealed that over one-third of all hoverfly species in the European continent were threatened with extinction.
