Alarming Surge in At-Risk Non-Managed Bee Varieties In European Nations

The count of native bee varieties in European nations confronting extinction has increased twofold over the past decade, and the number of threatened butterfly types has almost doubled.

This critical situation for essential pollinators was disclosed by research studies for the IUCN red list, which determined that at least over 170 bee varieties out of nearly two thousand were facing extinction in Europe.

The count of butterflies threatened with extinction in the European continent has increased from over thirty-five to 65 since the last study, performed 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.

Apart from their beauty and cultural importance, pollinating insects like bees and butterfly species are crucial elements for our health, our food systems and our economic systems – supporting the fruits, vegetables and seeds that feed us,” commented Grethel Aguilar. “The most recent European red list evaluations reveal major obstacles, with risks growing for butterfly species and vital native bee species.”

The factors of the rapid recent declines are the continuing harm or degradation of habitats caused by intensive agriculture and land abandonment, draining of wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of pollinator-friendly habitat substantially boosts the threat of local extinctions.

Global warming is also demonstrated to be a primary risk: 52% of all endangered butterfly species in Europe are threatened by the climate crisis – approximately double the number as a decade ago.

Nearly ninety percent of flowering plants in the European continent rely on insect pollination, as per Dr Denis Michez. “Unfortunately, native bee groups are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If native bees disappear, many native plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”

Fifteen species of bumblebee species, which perform a vital function in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willows along with 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 biological genus in the European continent, is now evaluated as severely threatened – the scientific classification closest to disappearance in the wild.

Butterfly species that are exclusively located on mountain peaks are particularly vulnerable to global warming as they need to move uphill as their habitats become hotter but eventually run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (exclusive to Europe) threatened with extinction.

In the Mediterranean area, varieties such as the highly at-risk grayling of Karpathos are imperilled by intense dry conditions and fires.

Meanwhile, in the Arctic region, climate change is causing the timberline to move north by tens of metres each year, with underbrush encroaching on wetlands and tundra. Warmer conditions also mean caribou can no longer cross the ice to browse northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.

“The largest living space for all these pollinating insects is bloom-filled grassy areas and that is declining quickly throughout Europe because of all these elements,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens care now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are land holders who are involved. It is hoped they can receive 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 agricultural output – and may enhance it – such as farmers creating flower-rich margins around their fields.

the EU’s environment commissioner, portrayed the conservation status of native bees, butterflies and additional pollinators as “dire”.

“Immediate and joint measures is necessary to confront this risk. Along with participating nations, the Commission of the European Union has put in place an European Union-wide observation system for pollinators based on the EU nature restoration regulation, which will aid in following our progress. Now, we need to concentrate on implementation and partnership with participating nations to preserve our pollinating insects,” she said.

The issuance of the assessments on bees and butterflies comes after the initial EU-wide study on hoverflies, a further crucial pollinator group. Issued in 2022, it disclosed that 37% of all hoverfly varieties in European nations were at risk of extinction.
