The number of non-managed bee types in the European continent confronting disappearance has increased twofold in the last ten years, while the count of at-risk butterfly species has almost doubled.
This critical situation for vital pollinating species was unveiled by scientific assessments for the IUCN red list, which found that at least over 170 bee varieties out of 1,928 were at risk of extinction in the European continent.
The number of butterfly types facing extinction in the European continent has increased from thirty-seven to 65 since the last study, performed over a decade past. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural significance, pollinating species like bees and butterfly species are lifelines for our physical condition, our food supplies and our financial structures – maintaining the fruits, veggies and seeds that feed us,” commented the IUCN’s director general. “The newest European red list evaluations reveal major obstacles, with threats growing for butterflies and crucial non-managed bee types.”
The reasons of the swift recent drops are the continuing damage or destruction of habitats caused by farming intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators significantly raises the danger of extinctions at local level.
Global heating is also shown to be a significant danger: 52% of all at-risk butterflies in European nations are endangered by the climate crisis – about twice as many as a ten years ago.
As many as 90% of plants that flower in European nations depend on pollination by animals, as per the wild bee assessment’s lead coordinator. “Sadly, wild bee colonies are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If wild bees vanish, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
15 varieties of bumblebee types, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for fertilizing trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the only species of this biological genus in Europe, is now assessed as critically at risk – the research category nearest to dying out in natural habitats.
Butterfly species that are exclusively located on mountain tops are highly susceptible to global warming as they must ascend higher as their habitats become more heated but eventually run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among over forty percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean, types such as the highly at-risk grayling of Karpathos are threatened by intense dry conditions and fires.
Meanwhile, in the Far North, global warming is causing the forest boundary to shift northward by many meters each year, with underbrush taking over wetlands and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice sheets to browse northern grasslands and prevent them from overgrowing. Eight types of butterflies are facing extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The greatest environment for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly in the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals are aware now and there’s a lot more understanding. Under the EU nature restoration legislation, all participating nations have to turn around the drop in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are property owners who are interested. We hope they can obtain the incentives that will help them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of steps for pollinators which won’t reduce food production – and may enhance it – such as agricultural producers developing bloom-filled edges around their cultivated areas.
EU commissioner for environment, portrayed the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to address this threat. Together with participating nations, the EU Commission has put in place an EU-wide tracking system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to concentrate on execution and cooperation with participating nations to preserve our pollinating insects,” she said.
The release of the assessments on bees and butterflies follows the initial European-wide assessment of hoverflies, another vital group of pollinators. Published in 2022, it revealed that thirty-seven percent of all hoverfly types in Europe were facing extinction.
