The number of wild bee species in the European continent confronting disappearance has over doubled in the last ten years, and the count of threatened butterfly species has almost doubled.
This critical situation for essential pollinating species was revealed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee types out of over 1900 were facing extinction in European nations.
The number of butterflies facing extinction in European nations has risen from 37 to sixty-five since the last study, conducted over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their visual charm and cultural importance, pollinators like bees and butterfly species are lifelines for our physical condition, our food systems and our financial structures – sustaining the produce, vegetables and seeds that nourish us,” said the IUCN director general. “The most recent European red list evaluations reveal major obstacles, with risks increasing for butterfly species and vital wild bee species.”
The factors of the rapid recent declines are the ongoing damage or destruction of habitats caused by farming intensification and deserted farmland, draining wetlands, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of habitat friendly to pollinators substantially boosts the threat of local extinctions.
Global heating is also demonstrated to be a primary risk: 52% of all at-risk butterfly species in Europe are endangered by the climate change crisis – approximately double the number as a ten years ago.
Nearly ninety percent of blooming plants in European nations rely on insect pollination, as per the lead coordinator of the wild bee assessment. “Unfortunately, wild bee populations are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If wild bees disappear, 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 species, which have an essential part in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for pollinating trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the sole species of this genus group in Europe, is now classified as severely threatened – the scientific classification most akin to disappearance in the wild.
Butterflies that are solely present on high-altitude areas are highly susceptible to global heating as they must ascend higher as their environments become hotter but ultimately have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling butterfly are imperilled by intense drought and wildfires.
Meanwhile, in the Far North, global warming is leading to the tree line to move north by many meters each year, with bushes taking over marsh and tundra. Hotter climates also mean caribou can no more cross the ice to feed on Arctic grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The greatest habitat for all these pollinating species is bloom-filled grassy areas and that is declining quickly throughout the European continent because of all these elements,” remarked Martin Warren. “The positive thing is that so many citizens are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to turn around the drop in pollinators by twenty-thirty, and they are going to have to initiate measures. There are land holders who are involved. We hope they can get the incentives that will help them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of action for pollinating species which will not decrease crop yields – and might boost it – such as agricultural producers creating margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, portrayed the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Urgent and collective action is needed to tackle this risk. Together with participating nations, the European Commission has implemented an European Union-wide tracking system for pollinators based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to focus on execution and collaboration with member countries to safeguard our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the first Europe-wide assessment of hoverflies, another crucial pollinator group. Released in 2022, it showed that over one-third of all hoverfly types in the European continent were facing extinction.
