The number of non-managed bee species in the European continent experiencing extinction has over doubled during the previous ten-year period, and the total of endangered butterfly types has almost doubled.
This critical situation for vital pollinators was unveiled by scientific assessments for the red list of threatened species, which determined that at least one hundred seventy-two bee species out of 1,928 were at risk of extinction in Europe.
The total of butterfly types at risk of extinction in Europe has grown from over thirty-five to sixty-five since the earlier research, carried out a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their aesthetic appeal and cultural significance, pollinators like bees and butterfly species are crucial elements for our physical condition, our food chains and our economic systems – maintaining the fruits, vegetables and seeds that feed us,” said the IUCN director general. “The most recent assessments of the European red list reveal significant difficulties, with dangers increasing for butterfly species and essential non-managed bee species.”
The causes of the swift recent drops are the persistent damage or destruction of natural habitats caused by agricultural intensification and deserted farmland, wetland drainage, livestock overgrazing, and the use of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators greatly increases the threat of local extinctions.
Global heating is also demonstrated to be a primary risk: 52% of all endangered butterfly species in European nations are imperilled by the climate emergency – roughly twice as many as a previous decade.
Up to ninety percent of flowering plants in Europe rely on pollination by animals, according to the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If native bees disappear, many wild plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, known for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the mainland and the single type of this genus group in the European continent, is now evaluated as severely threatened – the research category most akin to disappearance in the wild.
Butterfly types that are only found on mountain peaks are especially at risk to global heating as they must ascend higher as their habitats become hotter but in the end exhaust available 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) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling butterfly are threatened by severe drought and wildfires.
In the meantime, in the Far North, global heating is causing the timberline to move north by dozens of meters each year, with underbrush invading bog and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice to graze northern grasslands and prevent them from overgrowing. Eight butterfly species are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The greatest habitat for all these pollinating insects is grassland rich in flowers and that is declining quickly throughout the European continent because of all these elements,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to turn around the decrease in pollinating species by 2030, and they are going to have to begin taking action. There are property owners who are interested. We hope they can receive the encouragements that will support them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of action for pollinators which will not lower food production – and may enhance it – such as agricultural producers creating flower-rich margins around their fields.
Jessika Roswall, portrayed the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Prompt and unified steps is required to address this threat. In collaboration with member countries, the European Commission has put in place an EU-wide monitoring system for pollinating insects based on the EU nature restoration law, which will aid in following our development. Now, we need to prioritize application and cooperation with participating nations to safeguard our pollinating insects,” she said.
The issuance of the bee and butterfly assessments comes after the initial European-wide assessment of hoverflies, an additional essential pollinator group. Released in 2022, it revealed that thirty-seven percent of all hoverfly species in European nations were at risk of extinction.
