The number of wild bee varieties in Europe facing dying out has over doubled during the previous ten-year period, and the total of threatened butterfly types has almost doubled.
This pressing issue for vital pollinators was unveiled by scientific studies for the red list of threatened species, which found that at least one hundred seventy-two bee types out of over 1900 were threatened with extinction in Europe.
The count of butterfly types at risk of extinction in the European continent has increased from thirty-seven to over sixty since the last study, carried out a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
Apart from their beauty and cultural significance, pollinators like bees and butterfly species are essential supports for our health, our food systems and our economic systems – sustaining the fruits, veggies and seeds that feed us,” stated the IUCN director general. “The latest European red list evaluations reveal significant difficulties, with risks increasing for butterflies and essential native bee species.”
The causes of the quick recent decreases are the ongoing harm or degradation of natural habitats caused by agricultural intensification and abandoned land, draining wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The division of habitat friendly to pollinators significantly raises the risk of disappearances in specific areas.
Global heating is also revealed to be a major threat: Fifty-two percent of all threatened butterfly species in the European continent are imperilled by the climate emergency – approximately double the number as a decade ago.
As many as ninety percent of flowering plants in European nations require animal pollination, according to Dr Denis Michez. “Sadly, native bee populations are in drastic decline and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many wild plants might be threatened too – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
15 varieties of bumblebee types, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, recognized for pollinating trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the only species of this genus group in European nations, is now assessed as severely threatened – the scientific classification closest to dying out in natural habitats.
Butterflies that are exclusively located on mountain peaks are particularly vulnerable to global heating as they must ascend higher as their living spaces become more heated but in the end have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean, types such as the critically endangered Karpathos grayling are endangered by severe wildfires and drought.
At the same time, in the Far North, global heating is causing the forest boundary to shift northward by dozens of meters each year, with underbrush taking over wetlands and tundra. Higher temperatures also mean Arctic deer can no more cross the frozen water to graze Arctic grasslands and keep them open. Eight butterfly species are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet.
“The largest living space for all these pollinating insects is grassland rich in flowers and that is declining quickly across Europe because of all these reasons,” remarked Martin Warren. “The good news is that so many people care now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member states have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are landowners who are engaged. Let’s hope they can obtain the motivations that will support them on their way.”
According to the coordinator, there is “easy opportunities” in terms of measures for pollinating species which won’t reduce crop yields – and might boost it – such as agricultural producers establishing flower-rich margins around their cultivated areas.
EU commissioner for environment, characterized the preservation condition of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is required to tackle this risk. Along with member countries, the European Commission has implemented an European Union-wide observation system for pollinators based on the European Union nature restoration legislation, which will aid in following our progress. Now, we need to focus on execution and partnership with participating nations to protect our pollinating species,” she said.
The release of the assessments on bees and butterflies follows the pioneering EU-wide assessment of hoverflies, a further crucial pollinator group. Released in twenty-twenty-two, it showed that 37% of all hoverfly species in the European continent were facing extinction.
