The total of wild bee types in Europe experiencing extinction has more than doubled over the past decade, and the number of at-risk butterfly has nearly doubled.
This dire scenario for vital pollinating insects was disclosed by scientific assessments for the red list of threatened species, which established that at least one hundred seventy-two bee varieties out of over 1900 were at risk of extinction in European nations.
The count of butterfly species facing extinction in the European continent has grown from thirty-seven to over sixty since the last study, carried out 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural significance, pollinating species like bees along with butterflies are lifelines for our physical condition, our food systems and our economic systems – sustaining the produce, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The newest European red list evaluations reveal serious challenges, with threats mounting for butterfly species and vital wild bee species.”
The reasons of the swift recent drops are the continuing harm or degradation of habitats caused by agricultural intensification and abandoned land, wetland drainage, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat greatly increases the threat of local extinctions.
Climate change is also revealed to be a significant danger: Fifty-two percent of all threatened butterfly species in Europe are imperilled by the climate change crisis – approximately twofold the amount as a decade ago.
Nearly ninety percent of plants that flower in the European continent depend on animal pollination, according to the lead coordinator of the wild bee assessment. “Sadly, non-managed bee populations are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If non-managed bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen types of bumblebees, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for fertilizing trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the European continent and the sole species of this genus group in European nations, is now evaluated as severely threatened – the scientific category most akin to disappearance in the wild.
Butterfly species that are solely present on high-altitude areas are highly susceptible to climate change as they have to climb upward as their living spaces become hotter but in the end exhaust available space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling butterfly are threatened by severe drought and wildfires.
In the meantime, in the Arctic region, global heating is resulting in the timberline to move north by dozens of meters each year, with bushes invading marsh and tundra. Higher temperatures also mean reindeer can no more cross the ice sheets to feed on northern grasslands and keep them open. Eight butterfly species are facing extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest living space for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly throughout the European continent because of all these reasons,” remarked Martin Warren. “The encouraging aspect is that so many individuals care now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to halt the decrease in pollinating species by 2030, and they are going to have to initiate measures. There are landowners who are involved. We hope they can obtain the incentives that will support them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of measures for pollinating insects which will not lower agricultural output – and might boost it – such as growers establishing bloom-filled edges around their farmland.
the EU’s environment commissioner, characterized the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is necessary to address this danger. Together with member countries, the EU Commission has established an EU-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to focus on implementation and cooperation with participating nations to preserve our pollinating species,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the initial European-wide assessment of hoverflies, another vital pollinating insect category. Released in 2022, it disclosed that thirty-seven percent of all hoverfly types in European nations were facing extinction.
