The total of native bee species in the European continent confronting dying out has more than doubled over the past decade, and the total of at-risk butterfly types has almost doubled.
This dire scenario for vital pollinators was disclosed by research studies for the red list of threatened species, which established that at least 172 bee species out of 1,928 were at risk of extinction in European nations.
The number of butterfly types threatened with extinction in Europe has increased from over thirty-five to 65 since the earlier research, 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 importance, pollinating insects like bees along with butterflies are crucial elements for our health, our food supplies and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The newest European red list assessments reveal serious challenges, with threats growing for butterfly species and essential non-managed bee species.”
The factors of the quick recent decreases are the ongoing destruction or damage of habitats caused by agricultural intensification and deserted farmland, draining of wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoids. The breaking up of pollinator-friendly habitat greatly increases the risk of disappearances in specific areas.
Global warming is also shown to be a significant danger: Fifty-two percent of all at-risk butterfly types in the European continent are imperilled by the climate emergency – about twofold the amount as a decade ago.
Nearly 90% of blooming plants in the European continent require pollination by animals, according to the wild bee assessment’s lead coordinator. “Unfortunately, wild bee populations are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If native bees die out, many native plants might be at risk too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebee species, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 types of cellophane bee species, famous for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the only species of this genus in European nations, is now classified as severely threatened – the research category nearest to disappearance in the wild.
Butterfly types that are solely present on mountain peaks are highly susceptible to global warming as they have to climb upward as their environments become hotter but ultimately run out of space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean area, types such as the highly at-risk Karpathos grayling are imperilled by severe drought and wildfires.
In the meantime, in the Far North, global heating is leading to the tree line to shift northward by many meters each year, with underbrush encroaching on wetlands and tundra. Hotter climates also mean caribou can not anymore cross the ice sheets to graze northern grasslands and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest environment for all these pollinators is grassland rich in flowers and that is disappearing very fast in Europe because of all these elements,” stated a lead coordinator for the butterfly assessment. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all participating nations have to turn around the drop in pollinating insects by the year 2030, and they are going to have to initiate measures. There are land holders who are interested. Let’s hope they can receive the incentives that will help them on their way.”
As stated by Warren, there is “readily achievable actions” in terms of steps for pollinators which won’t reduce food production – and may enhance it – such as agricultural producers creating margins rich in flowers around their farmland.
EU commissioner for environment, described the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Prompt and unified steps is required to confront this threat. Together with participating nations, the EU Commission has put in place an Europe-wide monitoring system for pollinators based on the EU nature restoration regulation, which will aid in following our progress. Now, we need to prioritize implementation and cooperation with member states to safeguard our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies comes after the first EU-wide assessment of hoverflies, a further crucial pollinator group. Published in 2022, it disclosed that over one-third of all hoverfly varieties in Europe were at risk of extinction.
