Alarming Rise in Threatened Wild Bee Types In European Nations

The total of native bee varieties in the European continent experiencing disappearance has increased twofold in the last ten years, while the count of at-risk butterfly has close to doubled.

This pressing issue for essential pollinators was revealed by research studies for the red list of threatened species, which determined that at least over 170 bee species out of 1,928 were threatened with extinction in Europe.

The count of butterflies threatened with extinction in Europe has increased from 37 to sixty-five since the last study, conducted over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.

In addition to their visual charm and cultural significance, pollinating insects like bees and butterflies are lifelines for our physical condition, our food supplies and our economic systems – maintaining the produce, vegetables and seeds that feed us,” stated the IUCN’s director general. “The most recent European red list evaluations reveal significant difficulties, with risks increasing for butterfly types and vital native bee types.”

The reasons of the swift recent drops are the continuing damage or destruction of natural habitats caused by agricultural intensification and deserted farmland, wetland drainage, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the risk of disappearances in specific areas.

Climate change is also demonstrated to be a major threat: Over half of all endangered butterflies in Europe are threatened by the climate change crisis – roughly double the number as a decade ago.

As many as ninety percent of plants that flower in European nations rely on animal pollination, as stated by Dr Denis Michez. “Unfortunately, non-managed bee colonies are in sharp decrease and are not easily replaceable by domesticated hives,” he said. “If native bees die out, many native plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”

Fifteen species of bumblebees, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the single type of this biological genus in European nations, is now classified as critically at risk – the research category most akin to dying out in natural habitats.

Butterfly species that are only found on high-altitude areas are especially at risk to global heating as they need to move uphill as their habitats become hotter but ultimately run out of space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of European endemics (solely present in Europe) threatened with extinction.

In the Mediterranean area, varieties such as the severely threatened grayling of Karpathos are endangered by intense dry conditions and fires.

In the meantime, in the Far North, global warming is causing the forest boundary to move north by many meters each year, with underbrush invading wetlands and tundra. Warmer conditions also mean Arctic deer can no more cross the ice to feed on Arctic grasslands and keep them open. Eight types of butterflies are facing extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet.

“The largest habitat for all these pollinating insects is grassland rich in flowers and that is disappearing very fast throughout Europe because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to reverse the decrease in pollinators by the year 2030, and they are going to have to initiate measures. There are landowners who are interested. It is hoped they can receive the incentives that will support them on their way.”

As per Warren, there is “easy opportunities” in terms of measures for pollinating species which won’t reduce food production – and might boost it – such as agricultural producers establishing flower-rich margins around their cultivated areas.

Jessika Roswall, characterized the preservation condition of wild bees, butterflies and other pollinators as “critical”.

“Immediate and joint measures is necessary to confront this danger. Together with member states, the Commission of the European Union has implemented an Europe-wide monitoring system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to concentrate on implementation and cooperation with member countries to preserve our pollinators,” she said.

The issuance of the assessments on bees and butterflies comes after the pioneering Europe-wide study on hoverflies, a further essential group of pollinators. Issued in 2022, it revealed that 37% of all hoverfly types in the European continent were facing extinction.
