The total of wild bee species in the European continent confronting disappearance has more than doubled in the last ten years, whereas the count of at-risk butterfly has almost doubled.
This dire scenario for vital pollinating insects was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee varieties out of 1,928 were threatened with extinction in Europe.
The total of butterfly types facing extinction in the European continent has increased from 37 to sixty-five since the earlier research, performed 14 years ago. One species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural significance, pollinators like bees and butterfly species are lifelines for our well-being, our food systems and our economies – supporting the fruits, vegetables and seeds that nourish us,” commented the IUCN’s director general. “The newest European red list evaluations reveal serious challenges, with risks growing for butterfly species and essential non-managed bee species.”
The reasons of the swift recent drops are the continuing harm or degradation of living environments caused by farming intensification and deserted farmland, draining of wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the danger of local extinctions.
Climate change is also revealed to be a major threat: Fifty-two percent of all threatened butterfly species in the European continent are threatened by the climate crisis – about twofold the amount as a decade ago.
Nearly nine out of ten of blooming plants in the European continent rely on animal pollination, as per the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in severe drop and cannot readily be substituted by managed colonies,” he said. “If wild bees die out, many native plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen species of bumblebee types, which play a crucial role in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the only species of this genus group in Europe, is now evaluated as critically at risk – the scientific classification closest to extinction in the wild.
Butterflies that are solely present on mountain peaks are highly susceptible to global heating as they need to move uphill as their living spaces become warmer but eventually exhaust available space. In the southern part of Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling butterfly are endangered by extreme drought and wildfires.
Meanwhile, in the Arctic region, global warming is causing the timberline to shift northward by tens of metres each year, with bushes taking over marsh and tundra. Hotter climates also mean caribou can no more cross the frozen water to feed on Arctic grasslands and keep them open. Eight types of butterflies are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The greatest habitat for all these pollinating species is grassland rich in flowers and that is vanishing rapidly across Europe because of all these elements,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many people care now and there’s a lot more consciousness. Under the European Union nature restoration law, all member states have to halt the decrease in pollinators by twenty-thirty, and they are going to have to start doing something. There are property owners who are interested. It is hoped they can get the encouragements that will assist them on their way.”
As per Martin Warren, there is “low-hanging fruit” in terms of measures for pollinating species which will not lower agricultural output – and might boost it – such as agricultural producers creating bloom-filled edges around their farmland.
Jessika Roswall, characterized the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is needed to confront this threat. Along with participating nations, the European Commission has put in place an EU-wide tracking system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and collaboration with member states to safeguard our pollinating species,” she said.
The issuance of the assessments on bees and butterflies comes after the first EU-wide study on hoverflies, an additional crucial group of pollinators. Published in 2022, it showed that thirty-seven percent of all hoverfly varieties in Europe were facing extinction.
