The count of non-managed bee species in European nations facing disappearance has more than doubled over the past decade, while the number of at-risk butterfly has almost doubled.
This dire scenario for essential pollinators was unveiled by scientific assessments for the red list of threatened species, which established that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in the European continent.
The count of butterflies at risk of extinction in Europe has risen from thirty-seven to sixty-five since the previous assessment, carried out over a decade past. One species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural significance, pollinating insects like bees along with butterflies are crucial elements for our well-being, our food systems and our financial structures – sustaining the fruits, vegetables and seeds that sustain us,” said the IUCN’s director general. “The newest assessments of the European red list reveal major obstacles, with threats mounting for butterflies and vital wild bee types.”
The factors of the swift recent drops are the ongoing harm or degradation of natural habitats caused by farming intensification and land abandonment, draining wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoids. The breaking up of environments suitable for pollinators greatly increases the risk of local extinctions.
Climate change is also demonstrated to be a major threat: Over half of all threatened butterfly species in the European continent are endangered by the climate change crisis – roughly double the number as a decade ago.
Up to ninety percent of plants that flower in European nations depend on insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, wild bee populations are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If native bees disappear, many non-cultivated plants might be in danger as well – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebees, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the sole species of this genus group in Europe, is now classified as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterfly types that are solely present on mountain peaks are especially at risk to global heating as they need to move uphill as their habitats become more heated but in the end run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among more than 40% of European endemics (exclusive to Europe) at risk of extinction.
In the Mediterranean area, types such as the critically endangered grayling of Karpathos are imperilled by extreme dry conditions and fires.
At the same time, in the Arctic region, global heating is resulting in the forest boundary to advance northwards by dozens of meters each year, with bushes encroaching on marsh and tundra. Hotter climates also mean caribou can not anymore cross the frozen water to graze Arctic grasslands and maintain them clear. Eight butterfly species are facing extinction in this zone, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest environment for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly in European nations because of all these elements,” remarked Martin Warren. “The positive thing is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member states have to reverse the decrease in pollinators by 2030, and they are going to have to initiate measures. There are landowners who are involved. We hope they can obtain the incentives that will support them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of steps for pollinating insects which won’t reduce agricultural output – and may enhance it – such as agricultural producers establishing flower-rich margins around their cultivated areas.
Jessika Roswall, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is needed to confront this danger. In collaboration with participating nations, the Commission of the European Union has put in place an EU-wide observation system for pollinators based on the European Union nature restoration legislation, which will aid in following our development. Now, we need to concentrate on execution and partnership with member countries to protect our pollinators,” she said.
The release of the assessments on bees and butterflies follows the first European-wide study on hoverflies, a further essential pollinating insect category. Published in 2022, it revealed that 37% of all hoverfly species in the European continent were threatened with extinction.
