The total of wild bee species in the European continent experiencing dying out has increased twofold during the previous ten-year period, whereas the number of at-risk butterfly species has nearly doubled.
This critical situation for crucial pollinators was disclosed by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of nearly two thousand were at risk of extinction in the European continent.
The number of butterflies at risk of extinction in European nations has increased from over thirty-five to over sixty since the last study, conducted 14 years ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
“Beyond their aesthetic appeal and cultural importance, pollinating species like bees along with butterflies are lifelines for our health, our food chains and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” said the IUCN’s director general. “The most recent European red list evaluations reveal major obstacles, with dangers growing for butterfly species and vital native bee varieties.”
The factors of the quick recent decreases are the ongoing damage or destruction of living environments caused by agricultural intensification and land abandonment, draining wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat greatly increases the risk of disappearances in specific areas.
Global heating is also demonstrated to be a significant danger: Fifty-two percent of all at-risk butterfly types in the European continent are imperilled by the climate crisis – approximately twice as many as a decade ago.
Up to 90% of blooming plants in European nations rely on insect pollination, as per the wild bee assessment’s lead coordinator. “Unfortunately, wild bee populations are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If native bees die out, many wild plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebee species, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, recognized for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the sole species of this genus group in European nations, is now classified as critically at risk – the scientific category closest to dying out in natural habitats.
Butterflies that are exclusively located on mountain tops are particularly vulnerable to global heating as they need to move uphill as their living spaces become hotter but eventually exhaust available space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of European endemics (only found in Europe) at risk of extinction.
In the Mediterranean region, varieties such as the severely threatened Karpathos grayling are imperilled by extreme wildfires and drought.
Meanwhile, in the Arctic region, global warming is causing the timberline to advance northwards by tens of metres each year, with underbrush invading wetlands and tundra. Higher temperatures also mean caribou can not anymore cross the ice sheets to feed on northern grasslands and keep them open. Eight types of butterflies are facing extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast throughout Europe because of all these elements,” stated Martin Warren. “The encouraging aspect is that so many individuals are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all participating nations have to halt the decrease in pollinators by the year 2030, and they are going to have to start doing something. There are landowners who are engaged. Let’s hope they can obtain the motivations that will assist them on their way.”
According to Warren, there is “low-hanging fruit” in terms of steps for pollinating species which will not lower crop yields – and might boost it – such as growers establishing margins rich in flowers around their fields.
Jessika Roswall, portrayed the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is required to confront this threat. Along with member countries, the EU Commission has put in place an EU-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will aid in following our development. Now, we need to prioritize implementation and partnership with member states to preserve our pollinating insects,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the pioneering European-wide study on hoverflies, another essential pollinator group. Published in 2022, it showed that thirty-seven percent of all hoverfly varieties in the European continent were facing extinction.
