The number of native bee types in Europe facing disappearance has over doubled during the previous ten-year period, whereas the count of endangered butterfly species has close to doubled.
This dire scenario for essential pollinating species was revealed by research studies for the red list of threatened species, which determined that at least over 170 bee varieties out of over 1900 were at risk of extinction in the European continent.
The count of butterfly types threatened with extinction in European nations has increased from thirty-seven to sixty-five since the previous assessment, carried out over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural importance, pollinating species like bees and butterfly species are essential supports for our health, our food systems and our financial structures – supporting the produce, vegetables and seeds that feed us,” commented the IUCN director general. “The most recent European red list evaluations reveal significant difficulties, with dangers mounting for butterfly species and essential wild bee species.”
The causes of the rapid recent declines are the ongoing destruction or damage of natural habitats caused by farming intensification and land abandonment, draining wetlands, overgrazing by livestock, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat greatly increases the danger of local extinctions.
Climate change is also demonstrated to be a primary risk: Fifty-two percent of all endangered butterfly types in European nations are threatened by the climate change crisis – about twofold the amount as a previous decade.
Nearly ninety percent of blooming plants in the European continent require animal pollination, according to Dr Denis Michez. “Unfortunately, wild bee groups are in severe drop and are not easily replaceable by domesticated hives,” he said. “If wild bees vanish, many native plants might be at risk too – of which bloom-filled grasslands and lovely orchid types are just a couple of instances.”
15 varieties of bumblebee species, which play a crucial role in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for fertilizing trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the only species of this genus in Europe, is now classified as critically endangered – the scientific classification closest to disappearance in the wild.
Butterfly types that are exclusively located on mountain tops are highly susceptible to global heating as they have to climb upward as their living spaces become hotter but eventually exhaust available space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean area, types such as the severely threatened Karpathos grayling butterfly are endangered by severe wildfires and drought.
Meanwhile, in the Far North, climate change is causing the tree line to advance northwards by many meters each year, with scrub invading bog and tundra. Higher temperatures also mean reindeer can no longer cross the frozen water to graze northern grasslands and keep them open. Eight types of butterflies are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The largest living space for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly in Europe because of all these elements,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member states have to halt the drop in pollinators by 2030, and they are going to have to begin taking action. There are landowners who are engaged. It is hoped they can get the encouragements that will assist them on their way.”
According to Warren, there is “low-hanging fruit” in terms of steps for pollinating insects which will not lower crop yields – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
Jessika Roswall, described the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Prompt and unified steps is needed to confront this danger. Along with participating nations, the EU Commission has put in place an EU-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will aid in following our progress. Now, we need to focus on execution and collaboration with member countries to protect our pollinators,” she said.
The publication of the assessments on bees and butterflies is subsequent to the pioneering European-wide assessment of hoverflies, an additional crucial group of pollinators. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly species in Europe were threatened with extinction.
