Worrying Surge in Endangered Non-Managed Bee Types Throughout Europe

The count of wild bee species in Europe confronting disappearance has increased twofold during the previous ten-year period, whereas the count of endangered butterfly types has almost doubled.

This dire scenario for crucial pollinators was disclosed by scientific studies for the IUCN red list, which found that at least over 170 bee species out of nearly two thousand were threatened with extinction in European nations.

The total of butterfly species at risk of extinction in the European continent has grown from over thirty-five to 65 since the last study, conducted over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.

In addition to their visual charm and cultural importance, pollinators like bees along with butterflies are lifelines for our well-being, our food chains and our economic systems – maintaining the fruits, veggies and seeds that nourish us,” stated the IUCN director general. “The newest European red list assessments reveal serious challenges, with dangers increasing for butterflies and vital non-managed bee species.”

The causes of the swift recent drops are the persistent harm or degradation of natural habitats caused by agricultural intensification and abandoned land, draining of wetlands, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of pollinator-friendly habitat significantly raises the danger of extinctions at local level.

Global heating is also revealed to be a primary risk: Over half of all at-risk butterfly species in Europe are imperilled by the climate emergency – about double the number as a ten years ago.

Up to nine out of ten of plants that flower in Europe require insect pollination, as per Dr Denis Michez. “Sadly, non-managed bee populations are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees vanish, many wild plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”

15 varieties of bumblebee types, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the European continent and the sole species of this genus group in European nations, is now assessed as critically at risk – the scientific classification closest to dying out in natural habitats.

Butterfly types that are only found on mountain tops are especially at risk to global heating as they need to move uphill as their environments become hotter but in the end have no room left. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) at risk of extinction.

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

Meanwhile, in the Arctic Circle, global heating is causing the forest boundary to shift northward by tens of metres each year, with scrub invading bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. Eight types of butterflies are facing extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.

“The largest habitat for all these pollinators is flower-rich grassland and that is declining quickly throughout European nations because of all these factors,” stated a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to halt the decline in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are land holders who are interested. It is hoped they can obtain the motivations that will support them on their way.”

According to the coordinator, there is “low-hanging fruit” in terms of steps for pollinating species which won’t reduce food production – and could improve it – such as growers creating margins rich in flowers around their fields.

Jessika Roswall, described the preservation condition of native bees, butterflies and additional pollinators as “dire”.

“Immediate and joint measures is required to tackle this danger. Along with member countries, the European Commission has put in place an Europe-wide tracking system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to concentrate on execution and collaboration with participating nations to protect our pollinators,” she said.

The publication of the assessments on bees and butterflies comes after the first European-wide assessment of hoverflies, a further vital group of pollinators. Released in twenty-twenty-two, it showed that over one-third of all hoverfly types in European nations were threatened with extinction.
