The total of native bee types in European nations confronting dying out has more than doubled over the past decade, and the number of threatened butterfly has nearly doubled.
This critical situation for vital pollinating species was unveiled by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were facing extinction in European nations.
The number of butterflies at risk of extinction in the European continent has increased from over thirty-five to sixty-five since the previous assessment, carried out 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural value, pollinating insects like bees and butterflies are crucial elements for our health, our food supplies and our financial structures – supporting the produce, vegetables and seeds that nourish us,” said Grethel Aguilar. “The newest assessments of the European red list reveal major obstacles, with risks increasing for butterfly types and vital wild bee species.”
The causes of the quick recent decreases are the persistent harm or degradation of natural habitats caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the use of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat substantially boosts the risk of disappearances in specific areas.
Global warming is also demonstrated to be a significant danger: Over half of all threatened butterfly species in the European continent are threatened by the climate emergency – approximately twofold the amount as a ten years ago.
As many as nine out of ten of blooming plants in the European continent require insect pollination, according to the lead coordinator of the wild bee assessment. “Regrettably, native bee groups are in severe drop and cannot readily be substituted by managed colonies,” he said. “If native bees die out, many non-cultivated plants might be at risk too – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee types, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the mainland and the sole species of this genus group in European nations, is now assessed as severely threatened – the research category closest to dying out in natural habitats.
Butterfly species that are only found on high-altitude areas are particularly vulnerable to global heating as they have to climb upward as their habitats become more heated but ultimately run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among more than 40% of European endemics (exclusive to Europe) at risk of extinction.
In the Mediterranean region, species such as the critically endangered grayling of Karpathos are threatened by intense wildfires and drought.
Meanwhile, in the Arctic region, global heating is leading to the forest boundary to move north by tens of metres each year, with underbrush encroaching on wetlands and tundra. Hotter climates also mean caribou can no more cross the ice sheets to feed on Arctic meadows and keep them open. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The biggest environment for all these pollinating insects is flower-rich grassland and that is disappearing very fast across Europe because of all these factors,” remarked a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to reverse the drop in pollinating insects by 2030, and they are going to have to initiate measures. There are landowners who are interested. Let’s hope they can get the motivations that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of action for pollinating insects which will not decrease food production – and may enhance it – such as agricultural producers establishing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, characterized the preservation condition of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Immediate and joint measures is necessary to tackle this risk. Together with member states, the Commission of the European Union has put in place an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and collaboration with member states to protect our pollinators,” she said.
The publication of the bee and butterfly assessments follows the first European-wide assessment of hoverflies, a further essential group of pollinators. Released in twenty-twenty-two, it disclosed that 37% of all hoverfly types in Europe were at risk of extinction.
