The total of non-managed bee species in Europe facing extinction has over doubled over the past decade, while the number of at-risk butterfly types has close to doubled.
This dire scenario for crucial pollinating species was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee types out of nearly two thousand were facing extinction in European nations.
The total of butterflies threatened with extinction in the European continent has increased from thirty-seven to over sixty since the previous assessment, conducted over a decade past. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural significance, pollinating insects like bees and butterfly species are essential supports for our health, our food chains and our economic systems – maintaining the fruits, veggies and seeds that nourish us,” said the IUCN’s director general. “The newest European red list evaluations reveal significant difficulties, with dangers mounting for butterfly types and vital wild bee types.”
The factors of the swift recent drops are the ongoing harm or degradation of natural habitats caused by agricultural intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The breaking up of pollinator-friendly habitat greatly increases the risk of disappearances in specific areas.
Climate change is also shown to be a primary risk: 52% of all threatened butterfly types in Europe are threatened by the climate emergency – roughly twice as many as a ten years ago.
Up to 90% of flowering plants in European nations rely on pollination by animals, according to the lead coordinator of the wild bee assessment. “Regrettably, wild bee colonies are in severe drop and cannot readily be substituted by managed colonies,” he said. “If wild bees disappear, many native plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebee species, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, famous for aiding tree pollination such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the continent and the sole species of this biological genus in the European continent, is now assessed as critically endangered – the scientific classification 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 warmer but eventually exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling are endangered by intense wildfires and drought.
Meanwhile, in the Arctic Circle, climate change is leading to the tree line to shift northward by tens of metres each year, with bushes invading wetlands and tundra. Hotter climates also mean caribou can not anymore cross the ice sheets to feed on northern grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest living space for all these pollinators is grassland rich in flowers and that is disappearing very fast across European nations because of all these factors,” said Martin Warren. “The good news is that so many citizens are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all member states have to turn around the decline in pollinating insects by 2030, and they are going to have to initiate measures. There are property owners who are involved. We hope they can receive the incentives that will support them on their way.”
According to the coordinator, there is “easy opportunities” in terms of measures for pollinating insects which won’t reduce crop yields – and could improve it – such as agricultural producers creating margins rich in flowers around their farmland.
the EU’s environment commissioner, characterized the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is needed to confront this danger. Along with participating nations, the European Commission has implemented an European Union-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to concentrate on application and cooperation with member countries to preserve our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies is subsequent to the first Europe-wide assessment of hoverflies, a further vital pollinator group. Issued in 2022, it revealed that 37% of all hoverfly species in European nations were threatened with extinction.
