Concerning Rise in Endangered Wild Bee Types Throughout the European Continent
The total of wild bee species in the European continent facing disappearance has more than doubled in the last ten years, while the count of endangered butterfly types has nearly doubled.
This dire scenario for crucial pollinating insects was revealed by scientific studies for the IUCN red list, which determined that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in European nations.
The number of butterfly types facing extinction in Europe has risen from 37 to over sixty since the last study, performed over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural value, pollinators like bees and butterflies are essential supports for our physical condition, our food systems and our financial structures – supporting the produce, vegetables and seeds that feed us,” commented the IUCN’s director general. “The most recent European red list evaluations reveal major obstacles, with risks mounting for butterfly species and vital wild bee varieties.”
The causes of the rapid recent declines are the persistent harm or degradation of natural habitats caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the use of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Climate change is also demonstrated to be a primary risk: Over half of all threatened butterflies in the European continent are endangered by the climate emergency – about twofold the amount as a decade ago.
As many as nine out of ten of flowering plants in Europe require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, native bee groups are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If wild bees disappear, many wild plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee species, which play a crucial role in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for pollinating trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the sole species of this genus in Europe, is now assessed as critically at risk – the scientific category closest to dying out in natural habitats.
Butterfly types that are solely present on mountain peaks are highly susceptible to climate change as they have to climb upward as their habitats become more heated but ultimately run out of space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (solely present in Europe) facing extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling are threatened by severe dry conditions and fires.
In the meantime, in the Arctic region, global heating is causing the forest boundary to shift northward by dozens of meters each year, with scrub invading marsh and tundra. Higher temperatures also mean reindeer can no more cross the ice sheets to graze Arctic grasslands and prevent them from overgrowing. Eight butterfly species are facing extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest living space for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly across the European continent because of all these factors,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many people are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the decline in pollinators by the year 2030, and they are going to have to start doing something. There are landowners who are involved. Let’s hope they can receive the motivations that will assist them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of action for pollinating species which will not lower agricultural output – and might boost it – such as agricultural producers developing flower-rich margins around their cultivated areas.
the EU’s environment commissioner, characterized the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is required to tackle this risk. Together with member countries, the European Commission has implemented an EU-wide observation system for pollinating species based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to focus on implementation and collaboration with member states to safeguard our pollinating insects,” she said.
The release of the bee and butterfly assessments comes after the initial European-wide assessment of hoverflies, a further essential pollinating insect category. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in European nations were facing extinction.
