The number of native bee varieties in Europe confronting disappearance has over doubled over the past decade, whereas the total of at-risk butterfly species has close to doubled.
This pressing issue for essential pollinating insects was unveiled by scientific studies for the IUCN red list, which established that at least over 170 bee types out of over 1900 were facing extinction in European nations.
The count of butterfly types facing extinction in the European continent has grown from over thirty-five to over sixty since the earlier research, carried out a decade and a half ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their visual charm and cultural value, pollinating species like bees and butterfly species are essential supports for our health, our food supplies and our economies – sustaining the produce, vegetables and seeds that feed us,” commented Grethel Aguilar. “The latest European red list assessments reveal significant difficulties, with risks mounting for butterfly species and vital wild bee varieties.”
The causes of the quick recent decreases are the continuing damage or destruction of natural habitats caused by farming intensification and abandoned land, draining wetlands, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of habitat friendly to pollinators substantially boosts the risk of disappearances in specific areas.
Global heating is also demonstrated to be a primary risk: 52% of all endangered butterflies in the European continent are endangered by the climate crisis – roughly twofold the amount as a ten years ago.
Up to 90% of plants that flower in the European continent rely on insect pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, wild bee groups are in severe drop and cannot be easily replaced by managed colonies,” he said. “If wild bees disappear, many native plants might be at risk too – of which flower-rich meadows and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee species, which play a crucial role in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the European continent and the only species of this genus in Europe, is now classified as severely threatened – the scientific classification closest to disappearance in the wild.
Butterfly species that are only found on mountain tops are especially at risk to global warming as they have to climb upward as their environments become hotter but in the end run out of space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (exclusive to Europe) facing extinction.
In the Mediterranean region, varieties such as the highly at-risk grayling of Karpathos are threatened by extreme drought and wildfires.
In the meantime, in the Far North, global heating is resulting in the timberline to advance northwards by dozens of meters each year, with scrub taking over bog and tundra. Higher temperatures also mean caribou can no more cross the ice sheets to browse Arctic grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The largest habitat for all these pollinating species is grassland rich in flowers and that is vanishing rapidly throughout European nations because of all these elements,” stated a lead coordinator for the butterfly assessment. “The good news is that so many citizens are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the decline in pollinators by the year 2030, and they are going to have to initiate measures. There are property owners who are engaged. It is hoped they can get the incentives that will assist them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of measures for pollinating insects which will not lower food production – and could improve it – such as growers establishing margins rich in flowers around their fields.
the EU’s environment commissioner, described the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to confront this danger. Together with participating nations, the EU Commission has implemented an EU-wide observation system for pollinators based on the EU nature restoration law, which will aid in following our development. Now, we need to focus on implementation and partnership with participating nations to protect our pollinators,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the initial EU-wide study on hoverflies, another crucial pollinating insect category. Published in 2022, it revealed that 37% of all hoverfly types in the European continent were threatened with extinction.
