The total of wild bee varieties in European nations confronting dying out has over doubled in the last ten years, whereas the total of at-risk butterfly species has almost doubled.
This dire scenario for crucial pollinating insects was revealed by research studies for the IUCN red list, which found that at least over 170 bee types out of nearly two thousand were threatened with extinction in European nations.
The total of butterfly species facing extinction in European nations has increased from thirty-seven to sixty-five since the earlier research, performed 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their beauty and cultural importance, pollinating insects like bees and butterfly species are crucial elements for our health, our food supplies and our economies – supporting the fruits, veggies and seeds that nourish us,” stated the IUCN director general. “The newest European red list evaluations reveal serious challenges, with threats growing for butterfly types and essential non-managed bee species.”
The reasons of the swift recent drops are the persistent damage or destruction of natural habitats caused by farming intensification and deserted farmland, wetland drainage, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat greatly increases the threat of local extinctions.
Climate change is also revealed to be a significant danger: 52% of all threatened butterflies in the European continent are endangered by the climate crisis – approximately twice as many as a previous decade.
Up to ninety percent of flowering plants in the European continent require pollination by animals, as per the lead coordinator of the wild bee assessment. “Sadly, wild bee populations are in drastic decline and are not easily replaceable by managed bee colonies,” he said. “If native bees die out, many non-cultivated plants might be in danger as well – of which flower-rich meadows and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebee species, which perform a vital function in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, famous for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the single type of this genus group in European nations, is now assessed as critically endangered – the scientific classification nearest to dying out in natural habitats.
Butterfly species that are only found on mountain peaks are especially at risk to global warming as they have to climb upward as their habitats become hotter but in the end have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling are imperilled by extreme wildfires and drought.
At the same time, in the Arctic Circle, global warming is resulting in the timberline to advance northwards by dozens of meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean reindeer can no longer cross the ice sheets to browse Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest habitat for all these pollinating insects is flower-rich grassland and that is vanishing rapidly across European nations because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to halt the drop in pollinating species by twenty-thirty, and they are going to have to start doing something. There are property owners who are engaged. It is hoped they can get the incentives that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of measures for pollinators which will not decrease crop yields – and may enhance it – such as farmers developing flower-rich margins around their cultivated areas.
the EU’s environment commissioner, portrayed the protection status of wild bees, butterflies and other pollinators as “dire”.
“Prompt and unified steps is needed to confront this danger. Along with member states, the European Commission has implemented an Europe-wide observation system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to focus on implementation and collaboration with participating nations to safeguard our pollinating insects,” she said.
The release of the bee and butterfly assessments comes after the pioneering EU-wide assessment of hoverflies, a further vital group of pollinators. Released in 2022, it disclosed that over one-third of all hoverfly types in European nations were facing extinction.
