The count of non-managed bee varieties in the European continent confronting extinction has over doubled during the previous ten-year period, while the total of threatened butterfly types has almost doubled.
This pressing issue for vital pollinating species was disclosed by scientific studies for the red list of threatened species, which found that at least one hundred seventy-two bee types out of nearly two thousand were facing extinction in Europe.
The total of butterfly types threatened with extinction in Europe has risen from thirty-seven to 65 since the previous assessment, conducted a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural importance, pollinating species like bees and butterflies are crucial elements for our health, our food chains and our financial structures – supporting the fruits, vegetables and seeds that feed us,” stated the IUCN director general. “The newest European red list assessments reveal significant difficulties, with threats growing for butterfly types and crucial wild bee types.”
The factors of the swift recent drops are the ongoing destruction or damage of habitats caused by agricultural intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of habitat friendly to pollinators greatly increases the threat of local extinctions.
Climate change is also demonstrated to be a primary risk: Over half of all threatened butterfly types in European nations are endangered by the climate crisis – approximately twofold the amount as a previous decade.
Up to 90% of blooming plants in Europe depend on animal pollination, according to Dr Denis Michez. “Sadly, non-managed bee groups are in severe drop and are not easily replaceable by managed colonies,” he said. “If non-managed bees die out, many wild plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebees, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bees, known for pollinating trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the single type of this genus in Europe, is now classified as severely threatened – the scientific classification nearest to extinction in the wild.
Butterflies that are exclusively located on mountain peaks are especially at risk to global heating as they have to climb upward as their living spaces become warmer but ultimately exhaust available space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean, types such as the highly at-risk Karpathos grayling are imperilled by extreme dry conditions and fires.
At the same time, in the Arctic Circle, global warming is causing the timberline to advance northwards by many meters each year, with scrub taking over wetlands and tundra. Higher temperatures also mean reindeer can no longer cross the ice sheets to feed on northern grasslands and maintain them clear. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest living space for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast across the European continent because of all these factors,” said one of the lead coordinators of the butterflies assessment. “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 member countries have to halt the drop in pollinating insects by the year 2030, and they are going to have to initiate measures. There are land holders who are involved. We hope they can obtain the motivations that will assist them on their way.”
As per Warren, there is “low-hanging fruit” in terms of action for pollinating species which will not decrease crop yields – and might boost it – such as growers developing flower-rich margins around their farmland.
EU commissioner for environment, characterized the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is needed to confront this danger. Along with member states, the Commission of the European Union has put in place an EU-wide monitoring system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to prioritize application and partnership with member countries to preserve our pollinating insects,” she said.
The release of the assessments on bees and butterflies is subsequent to the first European-wide study on hoverflies, an additional vital pollinator group. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly types in Europe were threatened with extinction.
