The total of wild bee types in European nations experiencing disappearance has over doubled in the last ten years, while the number of threatened butterfly types has nearly doubled.
This dire scenario for essential pollinating species was unveiled by research studies for the IUCN red list, which determined that at least over 170 bee types out of nearly two thousand were at risk of extinction in the European continent.
The number of butterfly types at risk of extinction in the European continent has increased from thirty-seven to sixty-five since the previous assessment, carried out a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their aesthetic appeal and cultural value, pollinating species like bees along with butterflies are essential supports for our well-being, our food chains and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” said the IUCN’s director general. “The most recent assessments of the European red list reveal significant difficulties, with threats mounting for butterfly types and essential wild bee species.”
The factors of the swift recent drops are the continuing damage or destruction of living environments caused by agricultural intensification and deserted farmland, draining of wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Global heating is also demonstrated to be a major threat: Over half of all threatened butterfly species in Europe are threatened by the climate change crisis – roughly double the number as a ten years ago.
As many as ninety percent of flowering plants in the European continent depend on animal pollination, as per the lead coordinator of the wild bee assessment. “Unfortunately, native bee groups are in severe drop and are not easily replaceable by domesticated hives,” he said. “If wild bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a couple of instances.”
15 varieties of bumblebee species, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for aiding tree pollination such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the European continent and the sole species of this genus group in the European continent, is now evaluated as critically endangered – the scientific classification closest to dying out in natural habitats.
Butterfly types that are only found on high-altitude areas are especially at risk to climate change as they must ascend higher as their environments become warmer but ultimately have no room left. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling are endangered by severe drought and wildfires.
At the same time, in the Arctic Circle, global warming is resulting in the timberline to advance northwards by tens of metres each year, with underbrush invading wetlands and tundra. Warmer conditions also mean Arctic deer can no longer cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly throughout the European continent because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many citizens care now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to halt the decline in pollinating species by twenty-thirty, and they are going to have to start doing something. There are landowners who are engaged. It is hoped they can get the encouragements that will support them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of measures for pollinators which will not decrease agricultural output – and could improve it – such as growers developing bloom-filled edges around their cultivated areas.
EU commissioner for environment, described the protection status of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is necessary to tackle this danger. Together with participating nations, the Commission of the European Union has implemented an European Union-wide observation system for pollinating species based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to prioritize implementation and cooperation with member states to preserve our pollinators,” she said.
The issuance of the evaluations of bees along with butterflies is subsequent to the pioneering Europe-wide evaluation of hoverflies, a further essential pollinating insect category. Issued in 2022, it showed that thirty-seven percent of all hoverfly types in Europe were facing extinction.
