Worrying Increase in Threatened Native Bee Species In Europe

The count of wild bee varieties in Europe confronting extinction has over doubled during the previous ten-year period, and the total of threatened butterfly has almost doubled.

This critical situation for essential pollinators was revealed by scientific assessments for the red list of threatened species, which established that at least over 170 bee varieties out of over 1900 were facing extinction in European nations.

The number of butterfly species facing extinction in the European continent has risen from 37 to over sixty since the previous assessment, performed 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.

“Beyond their visual charm and cultural significance, pollinators like bees and butterflies are lifelines for our health, our food chains and our economic systems – supporting the produce, vegetables and seeds that feed us,” stated the IUCN director general. “The latest European red list evaluations reveal significant difficulties, with dangers growing for butterflies and vital wild bee species.”

The reasons of the quick recent decreases are the continuing destruction or damage of habitats caused by intensive agriculture and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoids. The breaking up of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.

Global warming is also shown to be a significant danger: Over half of all at-risk butterfly species in Europe are threatened by the climate change crisis – about twofold the amount as a decade ago.

As many as ninety percent of flowering plants in Europe depend on pollination by animals, according to the wild bee assessment’s lead coordinator. “Unfortunately, wild bee groups are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many non-cultivated plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”

Fifteen types of bumblebee types, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, 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 only species of this genus in Europe, is now evaluated as critically endangered – the scientific classification closest to disappearance in the wild.

Butterfly species that are exclusively located on mountain peaks are particularly vulnerable to climate change as they need to move uphill as their environments become warmer but ultimately exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (only found in Europe) at risk of extinction.

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

Meanwhile, in the Far North, global heating is resulting in the tree line to advance northwards by tens of metres each year, with bushes encroaching on bog and tundra. Higher temperatures also mean Arctic deer can no more cross the ice sheets to graze northern grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.

“The biggest habitat for all these pollinating species is flower-rich grassland and that is vanishing rapidly in European nations because of all these elements,” remarked a lead coordinator for the butterfly assessment. “The good news is that so many citizens care now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to turn around the decline in pollinating insects by 2030, and they are going to have to begin taking action. There are property owners who are involved. Let’s hope they can receive the motivations that will support them on their way.”

As per Warren, there is “easy opportunities” in terms of steps for pollinators which will not decrease food production – and may enhance it – such as agricultural producers developing bloom-filled edges around their cultivated areas.

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

“Urgent and collective action is necessary to address this threat. Together with participating nations, the Commission of the European Union has implemented an EU-wide observation system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and partnership with member countries to preserve our pollinating species,” she said.

The release of the bee and butterfly assessments is subsequent to the initial EU-wide evaluation of hoverflies, a further essential group of pollinators. Issued in twenty-twenty-two, it disclosed that over one-third of all hoverfly species in Europe were facing extinction.
