The count of non-managed bee varieties in European nations facing extinction has more than doubled in the last ten years, while the total of at-risk butterfly types has close to doubled.
This dire scenario for vital pollinating species was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee types out of 1,928 were threatened with extinction in European nations.
The number of butterfly types facing extinction in the European continent has grown from thirty-seven to sixty-five since the earlier research, performed 14 years ago. One species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees and butterfly species are essential supports for our physical condition, our food supplies and our economic systems – sustaining the produce, vegetables and seeds that feed us,” said the IUCN director general. “The most recent assessments of the European red list reveal significant difficulties, with risks mounting for butterfly species and vital wild bee types.”
The reasons of the rapid recent declines are the persistent harm or degradation of living environments caused by farming intensification and deserted farmland, draining of wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators substantially boosts the risk of extinctions at local level.
Global heating is also shown to be a significant danger: 52% of all threatened butterflies in Europe are threatened by the climate change crisis – about twice as many as a ten years ago.
As many as nine out of ten of flowering plants in the European continent require animal pollination, as per the wild bee assessment’s lead coordinator. “Regrettably, wild bee groups are in sharp decrease and cannot be easily replaced by managed colonies,” he said. “If non-managed bees die out, many native plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee types, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, recognized for aiding tree pollination such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the only species of this genus group in the European continent, is now classified as severely threatened – the scientific classification closest to disappearance in the wild.
Butterfly species that are solely present on mountain peaks are highly susceptible to climate change as they have to climb upward as their environments become warmer but ultimately exhaust available space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (only found in Europe) at risk of extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling butterfly are imperilled by intense wildfires and drought.
At the same time, in the Arctic Circle, global heating is causing the tree line to move north by dozens of meters each year, with underbrush encroaching on wetlands and tundra. Higher temperatures also mean reindeer can no longer cross the ice sheets to graze Arctic meadows and maintain them clear. 8 butterfly varieties are facing extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The greatest habitat for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly in the European continent because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to halt the drop in pollinators by 2030, and they are going to have to initiate measures. There are landowners who are interested. It is hoped they can get the incentives that will support them on their way.”
As per Warren, there is “readily achievable actions” in terms of steps for pollinators which will not lower crop yields – and could improve it – such as growers establishing margins rich in flowers around their farmland.
EU commissioner for environment, portrayed the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is required to confront this danger. Together with member countries, the Commission of the European Union has put in place an EU-wide observation system for pollinating insects based on the EU nature restoration regulation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and cooperation with participating nations to protect our pollinating insects,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the pioneering Europe-wide evaluation of hoverflies, another crucial group of pollinators. Issued in 2022, it disclosed that over one-third of all hoverfly types in the European continent were threatened with extinction.
