The number of wild bee species in Europe facing extinction has over doubled during the previous ten-year period, whereas the total of at-risk butterfly types has nearly doubled.
This critical situation for vital pollinating species was disclosed by research studies for the IUCN red list, which established that at least over 170 bee varieties out of nearly two thousand were at risk of extinction in Europe.
The count of butterfly species threatened with extinction in European nations has grown from over thirty-five to over sixty since the last study, carried out a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural value, pollinating insects like bees and butterfly species are crucial elements for our well-being, our food chains and our economies – maintaining the fruits, vegetables and seeds that feed us,” stated the IUCN director general. “The latest European red list evaluations reveal significant difficulties, with dangers increasing for butterfly types and vital non-managed bee types.”
The factors of the quick recent decreases are the continuing harm or degradation of living environments caused by intensive agriculture and land abandonment, draining wetlands, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of pollinator-friendly habitat substantially boosts the risk of local extinctions.
Global warming is also shown to be a major threat: 52% of all threatened butterfly species in European nations are imperilled by the climate crisis – roughly twofold the amount as a previous decade.
Nearly ninety percent of plants that flower in Europe require insect pollination, according to Dr Denis Michez. “Sadly, wild bee groups are in severe drop and cannot be easily replaced by managed colonies,” he said. “If native bees disappear, many native plants might be in danger as well – of which flower-rich meadows and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebee types, which perform a vital function in fertilizing peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the mainland and the only species of this genus in European nations, is now assessed as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterflies that are exclusively located on high-altitude areas are especially at risk to climate change as they must ascend higher as their environments become more heated but in the end exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue are among more than 40% of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling butterfly are imperilled by severe wildfires and drought.
Meanwhile, in the Arctic Circle, climate change is resulting in the timberline to move north by dozens of meters each year, with underbrush encroaching on bog and tundra. Hotter climates also mean reindeer can no longer cross the ice sheets to feed on Arctic grasslands and maintain them clear. Eight types of butterflies are facing extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The greatest environment for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly in the European continent because of all these factors,” said Martin Warren. “The positive thing is that so many individuals are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the drop in pollinators by 2030, and they are going to have to start doing something. There are landowners who are involved. It is hoped they can get the encouragements that will support them on their way.”
As stated by the coordinator, there is “low-hanging fruit” in terms of action for pollinating species which won’t reduce food production – and may enhance it – such as farmers establishing flower-rich margins around their farmland.
the EU’s environment commissioner, characterized the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Immediate and joint measures is necessary to confront this danger. Along with member countries, the EU Commission has established an Europe-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will help to track our advancement. Now, we need to concentrate on execution and collaboration with member countries to safeguard our pollinators,” she said.
The issuance of the bee and butterfly assessments comes after the initial European-wide evaluation of hoverflies, a further essential group of pollinators. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly types in Europe were facing extinction.
