The count of native bee types in Europe facing extinction has more than doubled over the past decade, while the number of threatened butterfly species has almost doubled.
This pressing issue for crucial pollinators was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in the European continent.
The count of butterfly types facing extinction in Europe has grown from 37 to sixty-five since the last study, conducted 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural importance, pollinating species like bees and butterfly species are crucial elements for our health, our food supplies and our economic systems – supporting the produce, vegetables and seeds that nourish us,” said Grethel Aguilar. “The most recent European red list evaluations reveal major obstacles, with dangers mounting for butterfly types and crucial wild bee species.”
The factors of the swift recent drops are the ongoing harm or degradation of living environments caused by agricultural intensification and deserted farmland, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoids. The breaking up of pollinator-friendly habitat greatly increases the danger of disappearances in specific areas.
Climate change is also revealed to be a primary risk: Fifty-two percent of all at-risk butterfly types in Europe are imperilled by the climate change crisis – roughly twofold the amount as a previous decade.
As many as ninety percent of plants that flower in Europe require pollination by animals, as per the lead coordinator of the wild bee assessment. “Regrettably, wild bee populations are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If native bees die out, many non-cultivated plants might be at risk too – of which bloom-filled grasslands and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee species, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the single type of this biological genus in European nations, is now evaluated as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterflies that are only found on mountain peaks are particularly vulnerable to climate change as they need to move uphill as their habitats become warmer but eventually exhaust available space. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among over forty percent of species endemic to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling are threatened by severe wildfires and drought.
At the same time, in the Arctic region, global warming is causing the tree line to advance northwards by dozens of meters each year, with scrub invading marsh and tundra. Higher temperatures also mean caribou can no more cross the ice sheets to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest environment for all these pollinators is flower-rich grassland and that is declining quickly throughout the European continent because of all these elements,” remarked Martin Warren. “The encouraging aspect is that so many people care now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decline in pollinators by 2030, and they are going to have to start doing something. There are property owners who are interested. We hope they can receive the encouragements that will support them on their way.”
As per the coordinator, there is “low-hanging fruit” in terms of steps for pollinators which will not lower agricultural output – and may enhance it – such as farmers creating flower-rich margins around their cultivated areas.
Jessika Roswall, portrayed the protection status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is needed to confront this threat. Together with participating nations, the European Commission has established an Europe-wide observation system for pollinating insects based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to concentrate on execution and collaboration with participating nations to protect our pollinating species,” she said.
The release of the evaluations of bees along with butterflies comes after the initial European-wide evaluation of hoverflies, a further crucial group of pollinators. Published in 2022, it disclosed that over one-third of all hoverfly varieties in European nations were threatened with extinction.
