The count of wild bee species in Europe experiencing dying out has more than doubled over the past decade, whereas the total of threatened butterfly has almost doubled.
This dire scenario for essential pollinating species was revealed by scientific studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of 1,928 were threatened with extinction in the European continent.
The total of butterflies at risk of extinction in Europe has increased from 37 to 65 since the last study, conducted 14 years ago. One species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural importance, pollinating species like bees along with butterflies are crucial elements for our well-being, our food systems and our economies – supporting the produce, vegetables and seeds that feed us,” said the IUCN director general. “The newest European red list evaluations reveal serious challenges, with risks increasing for butterfly types and essential native bee types.”
The reasons of the swift recent drops are the continuing destruction or damage of habitats caused by farming intensification and abandoned land, wetland drainage, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the danger of local extinctions.
Global heating is also shown to be a primary risk: Fifty-two percent of all threatened butterfly species in Europe are imperilled by the climate emergency – roughly twofold the amount as a decade ago.
Up to 90% of flowering plants in European nations require animal pollination, as per the lead coordinator of the wild bee assessment. “Regrettably, native bee colonies are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees die out, many wild plants might be in danger as well – of which flower-rich meadows and beautiful orchid species are just a few examples.”
15 varieties of bumblebees, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the sole species of this genus group in Europe, is now classified as critically at risk – the research category nearest to dying out in natural habitats.
Butterfly types that are exclusively located on mountain peaks are highly susceptible to climate change as they need to move uphill as their environments become more heated but ultimately run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling butterfly are imperilled by severe dry conditions and fires.
Meanwhile, in the Far North, climate change is causing the forest boundary to move north by many meters each year, with underbrush invading marsh and tundra. Higher temperatures also mean reindeer can no longer cross the ice sheets to graze Arctic meadows and keep them open. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The biggest habitat for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly throughout Europe because of all these elements,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals care now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to turn around the decline in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are land holders who are involved. We hope they can obtain the encouragements that will assist them on their way.”
As stated by Warren, there is “low-hanging fruit” in terms of action for pollinating species which will not decrease crop yields – and could improve it – such as farmers developing margins rich in flowers around their fields.
the EU’s environment commissioner, characterized the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is required to confront this danger. Together with participating nations, the European Commission has implemented an European Union-wide observation system for pollinators based on the EU nature restoration regulation, which will aid in following our development. Now, we need to concentrate on execution and partnership with member states to safeguard our pollinators,” she said.
The issuance of the bee and butterfly assessments follows the initial Europe-wide evaluation of hoverflies, another essential pollinator group. Released in 2022, it showed that 37% of all hoverfly types in the European continent were facing extinction.
