Alarming Rise in Threatened Wild Bee Types Across Europe
The number of native bee types in Europe confronting dying out has more than doubled in the last ten years, and the count of at-risk butterfly has almost doubled.
This dire scenario for vital pollinating insects was disclosed by scientific assessments for the red list of threatened species, which found that at least 172 bee species out of over 1900 were at risk of extinction in Europe.
The total of butterfly types at risk of extinction in Europe has grown from thirty-seven to 65 since the last study, performed 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
Apart from their beauty and cultural significance, pollinating species like bees along with butterflies are crucial elements for our health, our food systems and our financial structures – maintaining the produce, vegetables and seeds that nourish us,” stated the IUCN director general. “The newest European red list evaluations reveal serious challenges, with dangers mounting for butterfly species and vital wild bee species.”
The factors of the swift recent drops are the ongoing destruction or damage of natural habitats caused by intensive agriculture and deserted farmland, draining wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.
Global heating is also revealed to be a primary risk: 52% of all threatened butterflies in European nations are imperilled by the climate emergency – approximately twofold the amount as a decade ago.
Nearly nine out of ten of plants that flower in Europe require insect pollination, as stated by Dr Denis Michez. “Sadly, wild bee groups are in severe drop and are not easily replaceable by managed bee colonies,” he said. “If native bees disappear, many non-cultivated plants might be in danger as well – of which meadows rich in flowers and attractive orchid varieties are just a few examples.”
15 varieties of bumblebees, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the mainland and the only species of this genus in European nations, is now assessed as severely threatened – the research category closest to dying out in natural habitats.
Butterflies that are only found on mountain peaks are highly susceptible to climate change as they have to climb upward as their habitats become warmer but ultimately have no room left. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean area, species such as the critically endangered grayling of Karpathos are threatened by intense wildfires and drought.
At the same time, in the Arctic region, global heating is causing the timberline to shift northward by tens of metres each year, with underbrush invading wetlands and tundra. Warmer conditions also mean caribou can not anymore cross the ice sheets to feed on Arctic grasslands and prevent them from overgrowing. Eight types of butterflies are at risk of extinction in this region, including Freyja’s fritillary and the Arctic ringlet.
“The greatest environment for all these pollinators is flower-rich grassland and that is declining quickly across the European continent because of all these reasons,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many people are concerned now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member states have to halt the decrease in pollinators by twenty-thirty, and they are going to have to initiate measures. There are land holders who are engaged. It is hoped they can get the incentives that will assist them on their way.”
As per the coordinator, there is “easy opportunities” in terms of measures for pollinating species which will not decrease food production – and could improve it – such as farmers creating bloom-filled edges around their farmland.
the EU’s environment commissioner, described the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Immediate and joint measures is required to confront this risk. In collaboration with member states, the Commission of the European Union has established an Europe-wide monitoring system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to concentrate on execution and partnership with member states to protect our pollinating insects,” she said.
The release of the assessments on bees and butterflies follows the pioneering Europe-wide evaluation of hoverflies, an additional vital pollinator group. Issued in 2022, it disclosed that over one-third of all hoverfly types in the European continent were facing extinction.
