The count of non-managed bee types in the European continent facing disappearance has more than doubled over the past decade, while the total of at-risk butterfly has almost doubled.
This critical situation for essential pollinating insects was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee types out of 1,928 were at risk of extinction in the European continent.
The total of butterflies facing extinction in European nations has grown from over thirty-five to sixty-five since the earlier research, carried out a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
“Beyond their visual charm and cultural significance, pollinating insects like bees along with butterflies are lifelines for our well-being, our food systems and our economies – sustaining the fruits, veggies and seeds that nourish us,” commented the IUCN’s director general. “The latest European red list evaluations reveal significant difficulties, with dangers increasing for butterfly types and crucial wild bee varieties.”
The reasons of the swift recent drops are the ongoing damage or destruction of living environments caused by intensive agriculture and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoid chemicals. The breaking up of habitat friendly to pollinators greatly increases the risk of local extinctions.
Climate change is also demonstrated to be a major threat: 52% of all threatened butterflies in Europe are imperilled by the climate crisis – about twofold the amount as a decade ago.
Nearly 90% of flowering plants in European nations require pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If wild bees disappear, many wild plants might be at risk too – of which flower-rich meadows and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bee species, known for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the single type of this genus group in Europe, is now evaluated as critically endangered – the scientific category closest to disappearance in the wild.
Butterflies that are solely present on mountain peaks are particularly vulnerable to climate change as they need to move uphill as their environments become warmer but in the end run out of space. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among more than 40% of species endemic to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling are imperilled by severe wildfires and drought.
Meanwhile, in the Arctic region, climate change is causing the timberline to advance northwards by many meters each year, with scrub taking over wetlands and tundra. Warmer conditions also mean Arctic deer can no longer cross the ice sheets to feed on Arctic grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest environment for all these pollinators is grassland rich in flowers and that is declining quickly across the European continent because of all these reasons,” remarked 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 member states have to reverse the decrease in pollinators by twenty-thirty, and they are going to have to begin taking action. There are property owners who are interested. Let’s hope they can obtain the motivations that will support them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of steps for pollinators which won’t reduce food production – and may enhance it – such as farmers establishing flower-rich margins around their fields.
Jessika Roswall, described the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is required to confront this risk. Together with member countries, the EU Commission has implemented an European Union-wide observation system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to concentrate on implementation and cooperation with member states to preserve our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies follows the pioneering European-wide study on hoverflies, another crucial group of pollinators. Released in 2022, it showed that thirty-seven percent of all hoverfly types in European nations were facing extinction.
