Concerning Surge in Threatened Non-Managed Bee Varieties In European Nations

The count of native bee types in European nations facing dying out has increased twofold during the previous ten-year period, and the number of endangered butterfly species has nearly doubled.

This pressing issue for essential pollinating insects was unveiled by scientific assessments for the red list of threatened species, which found that at least over 170 bee types out of over 1900 were threatened with extinction in the European continent.

The number of butterfly species threatened with extinction in European nations has risen from thirty-seven to 65 since the previous assessment, conducted over a decade past. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.

“Beyond their aesthetic appeal and cultural importance, pollinators like bees and butterflies are essential supports for our well-being, our food chains and our financial structures – maintaining the produce, vegetables and seeds that sustain us,” commented the IUCN director general. “The latest European red list assessments reveal serious challenges, with threats mounting for butterfly types and essential native bee types.”

The causes of the swift recent drops are the ongoing destruction or damage of natural habitats caused by farming intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the threat of local extinctions.

Climate change is also demonstrated to be a major threat: 52% of all at-risk butterfly species in European nations are imperilled by the climate crisis – approximately double the number as a decade ago.

Up to ninety percent of plants that flower in Europe rely on pollination by animals, according to the wild bee assessment’s lead coordinator. “Unfortunately, wild bee populations are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees die out, many native plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”

15 varieties of bumblebees, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 types of cellophane bee species, famous for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the sole species of this biological genus in European nations, is now classified as critically at risk – the scientific classification most akin to disappearance in the wild.

Butterflies that are solely present on high-altitude areas are particularly vulnerable to global warming as they have to climb upward as their habitats become hotter but in the end exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (solely present in Europe) threatened with extinction.

In the Mediterranean, species such as the critically endangered Karpathos grayling are endangered by intense dry conditions and fires.

In the meantime, in the Far North, climate change is resulting in the timberline to shift northward by tens of metres each year, with underbrush encroaching on bog and tundra. Higher temperatures also mean reindeer can no longer cross the frozen water to browse northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.

“The greatest living space for all these pollinators is grassland rich in flowers and that is disappearing very fast in European nations because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to turn around the drop in pollinating insects by the year 2030, and they are going to have to initiate measures. There are landowners who are engaged. We hope they can receive the incentives that will support them on their way.”

According to the coordinator, there is “low-hanging fruit” in terms of steps for pollinating species which will not lower agricultural output – and could improve it – such as growers developing flower-rich margins around their farmland.

Jessika Roswall, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.

“Urgent and collective action is needed to address this danger. Together with member states, the EU Commission has implemented an EU-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to prioritize implementation and cooperation with participating nations to safeguard our pollinators,” she said.

The publication of the assessments on bees and butterflies comes after the initial European-wide study on hoverflies, another crucial pollinating insect category. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly types in Europe were facing extinction.
