Worrying Surge in Endangered Non-Managed Bee Varieties In European Nations

The total of wild bee species in Europe experiencing dying out has over doubled during the previous ten-year period, and the count of at-risk butterfly types has almost doubled.

This critical situation for crucial pollinating insects was unveiled by scientific studies for the red list of threatened species, which found that at least one hundred seventy-two bee varieties out of nearly two thousand were threatened with extinction in Europe.

The number of butterflies threatened with extinction in European nations has grown from thirty-seven to over sixty since the earlier research, performed a decade and a half ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.

Apart from their visual charm and cultural significance, pollinating species like bees along with butterflies are essential supports for our well-being, our food chains and our economic systems – maintaining the produce, vegetables and seeds that sustain us,” said the IUCN’s director general. “The most recent assessments of the European red list reveal significant difficulties, with risks mounting for butterflies and essential wild bee varieties.”

The reasons of the rapid recent declines are the continuing damage or destruction of natural habitats caused by farming intensification and abandoned land, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators greatly increases the danger of local extinctions.

Climate change is also shown to be a primary risk: Over half of all endangered butterfly types in European nations are endangered by the climate change crisis – roughly twofold the amount as a previous decade.

As many as nine out of ten of blooming plants in the European continent depend on pollination by animals, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee groups are in severe drop and are not easily replaceable by domesticated hives,” he said. “If non-managed bees disappear, many native plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a few examples.”

Fifteen species of bumblebee types, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the sole species of this genus group in European nations, is now assessed as severely threatened – the research category nearest to disappearance in the wild.

Butterfly species that are solely present on high-altitude areas are particularly vulnerable to global heating as they have to climb upward as their habitats become hotter but in the end exhaust available space. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (solely present in Europe) at risk of extinction.

In the Mediterranean, varieties such as the critically endangered Karpathos grayling butterfly are threatened by intense wildfires and drought.

At the same time, in the Arctic Circle, global heating is leading to the timberline to advance northwards by many meters each year, with bushes invading bog and tundra. Warmer conditions also mean reindeer can not anymore cross the ice to browse northern grasslands and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this region, including the fritillary of Freyja and the Arctic ringlet.

“The biggest living space for all these pollinating insects is flower-rich grassland and that is vanishing rapidly across Europe because of all these factors,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many people care now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to halt the decline in pollinating species by the year 2030, and they are going to have to start doing something. There are landowners who are engaged. It is hoped they can get the encouragements that will assist them on their way.”

As stated by Warren, there is “low-hanging fruit” in terms of action for pollinating insects which will not decrease crop yields – and may enhance it – such as farmers developing bloom-filled edges around their cultivated areas.

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

“Prompt and unified steps is needed to tackle this danger. Along with member states, the Commission of the European Union has implemented an Europe-wide observation system for pollinators based on the EU nature restoration law, which will aid in following our advancement. Now, we need to concentrate on execution and collaboration with participating nations to preserve our pollinating species,” she said.

The issuance of the evaluations of bees along with butterflies follows the initial Europe-wide study on hoverflies, another vital pollinator group. Issued in 2022, it showed that 37% of all hoverfly varieties in Europe were threatened with extinction.
