The number of non-managed bee varieties in Europe confronting dying out has increased twofold during the previous ten-year period, while the count of at-risk butterfly has almost doubled.
This dire scenario for crucial pollinating insects was unveiled by scientific assessments for the red list of threatened species, which determined that at least one hundred seventy-two bee types out of 1,928 were at risk of extinction in the European continent.
The count of butterfly types at risk of extinction in the European continent has risen from 37 to sixty-five since the earlier research, carried out a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their beauty and cultural significance, pollinators like bees and butterfly species are essential supports for our health, our food supplies and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” commented the IUCN’s director general. “The newest European red list evaluations reveal significant difficulties, with risks mounting for butterfly types and essential wild bee varieties.”
The factors of the swift recent drops are the persistent destruction or damage of living environments caused by agricultural intensification and abandoned land, draining of wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the threat of disappearances in specific areas.
Global warming is also revealed to be a primary risk: 52% of all threatened butterfly types in European nations are endangered by the climate emergency – approximately twice as many as a previous decade.
Nearly 90% of plants that flower in Europe require pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Sadly, native bee colonies are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees vanish, many wild plants might be at risk too – of which bloom-filled grasslands and beautiful orchid species are just a few examples.”
Fifteen species of bumblebee types, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the single type of this biological genus in the European continent, is now evaluated as critically endangered – the research category nearest to disappearance in the wild.
Butterfly species that are solely present on high-altitude areas are especially at risk to global warming as they need to move uphill as their environments become more heated but in the end have no room left. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (only found in Europe) facing extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling butterfly are imperilled by intense drought and wildfires.
At the same time, in the Arctic region, global heating is causing the timberline to advance northwards by tens of metres each year, with underbrush invading wetlands and tundra. Warmer conditions also mean caribou can not anymore cross the frozen water to browse northern grasslands and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this region, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The greatest habitat for all these pollinators is bloom-filled grassy areas and that is disappearing very fast throughout the European continent because of all these elements,” stated a lead coordinator for the butterfly assessment. “The positive thing is that so many citizens care now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to turn around the drop in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are land holders who are interested. It is hoped they can receive the motivations that will help them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of action for pollinating species which will not lower food production – and might boost it – such as growers creating flower-rich margins around their fields.
Jessika Roswall, characterized the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Urgent and collective action is required to address this risk. In collaboration with member states, the EU Commission has established an EU-wide observation system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to prioritize application and collaboration with participating nations to protect our pollinators,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the first European-wide evaluation of hoverflies, an additional vital group of pollinators. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly species in Europe were threatened with extinction.
