The total of native bee species in European nations experiencing extinction has more than doubled during the previous ten-year period, while the count of threatened butterfly species has almost doubled.
This critical situation for essential pollinators was disclosed by scientific assessments for the red list of threatened species, which found that at least over 170 bee species out of nearly two thousand were facing extinction in the European continent.
The count of butterfly species threatened with extinction in European nations has grown from thirty-seven to sixty-five since the previous assessment, performed a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
“Beyond their visual charm and cultural importance, pollinators like bees and butterfly species are crucial elements for our well-being, our food systems and our financial structures – sustaining the fruits, veggies and seeds that feed us,” stated the IUCN director general. “The most recent European red list assessments reveal significant difficulties, with threats mounting for butterfly species and crucial native bee types.”
The causes of the quick recent decreases are the continuing damage or destruction of habitats caused by agricultural intensification and land abandonment, draining wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators substantially boosts the danger of extinctions at local level.
Global heating is also shown to be a major threat: Fifty-two percent of all threatened butterfly types in Europe are imperilled by the climate emergency – approximately twice as many as a previous decade.
Up to nine out of ten of flowering plants in Europe rely on insect pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in severe drop and are not easily replaceable by managed colonies,” he said. “If wild bees disappear, many native plants might be threatened too – of which flower-rich meadows and lovely orchid types are just a few examples.”
Fifteen species of bumblebee species, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the continent and the sole species of this genus in the European continent, is now classified as severely threatened – the research category closest to dying out in natural habitats.
Butterfly types that are exclusively located on high-altitude areas are particularly vulnerable to global heating as they need to move uphill as their environments become warmer but ultimately have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean area, species such as the highly at-risk Karpathos grayling are threatened by intense drought and wildfires.
Meanwhile, in the Far North, global warming is causing the forest boundary to advance northwards by dozens of meters each year, with scrub taking over bog and tundra. Higher temperatures also mean caribou can no longer cross the frozen water to graze Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The largest living space for all these pollinating species is bloom-filled grassy areas and that is declining quickly in European nations because of all these elements,” stated a lead coordinator for the butterfly assessment. “The good news is that so many people care now and there’s a lot more understanding. Under the EU nature restoration legislation, all participating nations have to turn around the drop in pollinators by twenty-thirty, and they are going to have to begin taking action. There are land holders who are engaged. It is hoped they can obtain the encouragements that will help them on their way.”
As stated by Martin Warren, there is “low-hanging fruit” in terms of measures for pollinators which will not lower food production – and might boost it – such as growers developing flower-rich margins around their cultivated areas.
Jessika Roswall, portrayed the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to confront this risk. Together with participating nations, the European Commission has established an European Union-wide tracking system for pollinators based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to focus on execution and cooperation with participating nations to safeguard our pollinating species,” she said.
The release of the evaluations of bees along with butterflies follows the first EU-wide study on hoverflies, a further essential group of pollinators. Issued in 2022, it showed that over one-third of all hoverfly types in Europe were facing extinction.
