Concerning Rise in Threatened Wild Bee Types In the European Continent

The number of wild bee varieties in the European continent confronting disappearance has over doubled in the last ten years, and the total of threatened butterfly has close to doubled.

This pressing issue for essential pollinators was unveiled by research studies for the IUCN red list, which determined that at least over 170 bee species out of 1,928 were facing extinction in the European continent.

The total of butterfly types facing extinction in European nations has grown from 37 to 65 since the last study, performed a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.

In addition to their aesthetic appeal and cultural value, pollinating species like bees along with butterflies are lifelines for our health, our food supplies and our economic systems – supporting the fruits, veggies and seeds that nourish us,” commented the IUCN director general. “The most recent assessments of the European red list reveal major obstacles, with threats mounting for butterfly types and essential non-managed bee types.”

The causes of the rapid recent declines are the persistent harm or degradation of habitats caused by intensive agriculture and land abandonment, wetland drainage, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of pollinator-friendly habitat greatly increases the danger of local extinctions.

Global warming is also revealed to be a significant danger: 52% of all threatened butterfly species in Europe are endangered by the climate crisis – approximately twofold the amount as a ten years ago.

As many as 90% of blooming plants in European nations rely on pollination by animals, as stated by the lead coordinator of the wild bee assessment. “Regrettably, native bee colonies are in drastic decline and are not easily replaceable by managed bee colonies,” he said. “If native 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 bumblebee species, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for pollinating trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the sole species of this genus in the European continent, is now evaluated as critically at risk – the scientific classification most akin to extinction in the wild.

Butterflies that are exclusively located on mountain peaks are particularly vulnerable to global heating as they have to climb upward as their living spaces become more heated but ultimately have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among over forty percent of types unique to Europe (solely present in Europe) at risk of extinction.

In the Mediterranean region, types such as the highly at-risk Karpathos grayling are imperilled by severe drought and wildfires.

In the meantime, in the Far North, climate change is resulting in the timberline to move north by tens of metres each year, with bushes invading bog and tundra. Hotter climates also mean caribou can no longer cross the ice to feed on Arctic grasslands and keep them open. Eight types of butterflies are at risk of extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.

“The largest living space for all these pollinators is grassland rich in flowers and that is vanishing rapidly in the European continent because of all these reasons,” said Martin Warren. “The encouraging aspect is that so many individuals are aware now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to reverse the decrease in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are landowners who are interested. Let’s hope they can obtain the encouragements that will help them on their way.”

As per Warren, there is “readily achievable actions” in terms of measures for pollinating species which will not lower food production – and might boost it – such as growers creating bloom-filled edges around their farmland.

EU commissioner for environment, described the conservation status of wild bees, butterflies and other pollinators as “critical”.

“Prompt and unified steps is required to confront this risk. Together with member states, the EU Commission has put in place an Europe-wide observation system for pollinating insects based on the European Union nature restoration legislation, which will help to track our advancement. Now, we need to focus on application and cooperation with member countries to protect our pollinating insects,” she said.

The release of the evaluations of bees along with butterflies follows the first EU-wide evaluation of hoverflies, an additional vital pollinating insect category. Released in 2022, it disclosed that over one-third of all hoverfly species in European nations were threatened with extinction.
