Alarming Rise in At-Risk Native Bee Species Across the European Continent
The total of non-managed bee types in European nations experiencing disappearance has more than doubled in the last ten years, and the count of at-risk butterfly has nearly doubled.
This pressing issue for essential pollinating species was disclosed by research studies for the red list of threatened species, which determined that at least one hundred seventy-two 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 increased from over thirty-five to 65 since the earlier research, conducted a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural significance, pollinators like bees and butterflies are lifelines for our physical condition, our food systems and our economies – maintaining the fruits, veggies and seeds that feed us,” stated Grethel Aguilar. “The newest European red list evaluations reveal serious challenges, with risks growing for butterflies and crucial native bee species.”
The causes of the swift recent drops are the ongoing damage or destruction of living environments caused by intensive agriculture and land abandonment, draining of wetlands, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators significantly raises the risk of disappearances in specific areas.
Climate change is also revealed to be a significant danger: Fifty-two percent of all endangered butterfly types in Europe are imperilled by the climate change crisis – about twice as many as a previous decade.
Nearly ninety percent of blooming plants in Europe depend on pollination by animals, as stated by the lead coordinator of the wild bee assessment. “Regrettably, wild bee colonies are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If native bees die out, many native plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”
15 varieties of bumblebee species, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the single type of this genus in Europe, is now classified as severely threatened – the scientific category nearest to extinction in the wild.
Butterflies that are exclusively located on high-altitude areas are especially at risk to global heating as they must ascend higher as their habitats become more heated but in the end have no room left. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean area, types such as the highly at-risk Karpathos grayling butterfly are threatened by severe drought and wildfires.
In the meantime, in the Arctic Circle, global warming is resulting in the tree line to shift northward by tens of metres each year, with scrub encroaching on marsh and tundra. Higher temperatures also mean caribou can no more cross the ice to graze Arctic meadows and keep them open. Eight butterfly species are threatened with extinction in this region, including the fritillary of Freyja and the ringlet of the Arctic.
“The largest habitat for all these pollinating insects is grassland rich in flowers and that is disappearing very fast throughout the European continent because of all these elements,” 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 consciousness. Under the European Union nature restoration law, all member countries have to halt the drop in pollinating species by the year 2030, and they are going to have to initiate measures. There are property owners who are involved. Let’s hope they can obtain the motivations that will support them on their way.”
As per Warren, there is “low-hanging fruit” in terms of action for pollinating insects which will not lower food production – and may enhance it – such as agricultural producers creating margins rich in flowers around their farmland.
the EU’s environment commissioner, described the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Urgent and collective action is required to tackle this threat. In collaboration with participating nations, the EU Commission has put in place an Europe-wide observation system for pollinating species based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to concentrate on application and partnership with participating nations to protect our pollinating species,” she said.
The release of the assessments on bees and butterflies follows the initial Europe-wide study on hoverflies, a further crucial pollinator group. Issued in 2022, it showed that over one-third of all hoverfly species in the European continent were threatened with extinction.
