The total of wild bee varieties in Europe experiencing extinction has increased twofold over the past decade, whereas the total of endangered butterfly species has close to doubled.
This critical situation for essential pollinating insects was revealed by scientific studies for the IUCN red list, which established that at least one hundred seventy-two bee types out of nearly two thousand were at risk of extinction in the European continent.
The number of butterflies at risk of extinction in the European continent has increased from thirty-seven to 65 since the earlier research, conducted a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural significance, pollinating species like bees and butterflies are crucial elements for our health, our food systems and our economies – supporting the fruits, veggies and seeds that nourish us,” said Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with dangers mounting for butterfly species and vital native bee species.”
The causes of the swift recent drops are the ongoing damage or destruction of living environments caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat significantly raises the danger of disappearances in specific areas.
Global heating is also revealed to be a primary risk: Fifty-two percent of all endangered butterfly types in the European continent are imperilled by the climate change crisis – roughly twice as many as a ten years ago.
Up to ninety percent of blooming plants in European nations rely on insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in sharp decrease and cannot readily be substituted by managed bee colonies,” he said. “If wild bees die out, many wild plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
15 varieties of bumblebee types, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the sole species of this biological genus in Europe, is now assessed as critically at risk – the scientific classification nearest to disappearance in the wild.
Butterfly species that are only found on mountain tops are particularly vulnerable to climate change as they have to climb upward as their environments become more heated but ultimately have no room left. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (solely present in Europe) facing extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling are endangered by intense wildfires and drought.
At the same time, in the Arctic region, climate change is causing the timberline to advance northwards by many meters each year, with scrub taking over marsh and tundra. Higher temperatures also mean reindeer can no more cross the ice sheets to browse northern grasslands and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The biggest living space for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly throughout the European continent because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all participating nations have to turn around the drop in pollinating insects by the year 2030, and they are going to have to begin taking action. There are land holders who are involved. We hope they can obtain the encouragements that will assist them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of measures for pollinating species which won’t reduce agricultural output – and could improve it – such as farmers creating margins rich in flowers around their fields.
EU commissioner for environment, described the conservation status of native bees, butterflies and additional pollinators as “critical”.
“Immediate and joint measures is needed to address this risk. Together with participating nations, the Commission of the European Union has put in place an European Union-wide monitoring system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to concentrate on application and partnership with member countries to protect our pollinating species,” she said.
The issuance of the bee and butterfly assessments is subsequent to the pioneering EU-wide study on hoverflies, another vital pollinating insect category. Released in twenty-twenty-two, it revealed that over one-third of all hoverfly varieties in the European continent were at risk of extinction.
