The count of wild bee types in European nations confronting dying out has increased twofold over the past decade, whereas the number of endangered butterfly has close to doubled.
This pressing issue for vital pollinating species was revealed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee varieties out of nearly two thousand were threatened with extinction in Europe.
The total of butterfly types facing extinction in the European continent has risen from over thirty-five to over sixty since the last study, conducted 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural value, pollinating insects like bees and butterfly species are crucial elements for our physical condition, our food chains and our economic systems – supporting the produce, vegetables and seeds that sustain us,” commented the IUCN’s director general. “The latest European red list assessments reveal major obstacles, with risks growing for butterfly species and essential native bee species.”
The causes of the rapid recent declines are the persistent harm or degradation of habitats caused by agricultural intensification and land abandonment, draining wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Global warming is also revealed to be a significant danger: Fifty-two percent of all endangered butterfly types in Europe are endangered by the climate emergency – approximately double the number as a decade ago.
Nearly ninety percent of flowering plants in Europe require animal pollination, as per Dr Denis Michez. “Sadly, non-managed bee colonies are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If native bees disappear, many native plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebees, which perform a vital function in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the mainland and the sole species of this biological genus in European nations, is now evaluated as severely threatened – the scientific classification nearest to dying out in natural habitats.
Butterflies that are solely present on mountain tops are highly susceptible to climate change as they have to climb upward as their living spaces become more heated but eventually exhaust available space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, species such as the severely threatened Karpathos grayling are endangered by intense wildfires and drought.
Meanwhile, in the Arctic region, climate change is leading to the timberline to shift northward by many meters each year, with scrub taking over bog and tundra. Warmer conditions also mean Arctic deer can no more cross the ice sheets to graze Arctic meadows and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The largest living space for all these pollinating insects is bloom-filled grassy areas and that is declining quickly in the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to reverse 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 motivations that will support them on their way.”
As per the coordinator, there is “easy opportunities” in terms of action for pollinating insects which will not lower agricultural output – and may enhance it – such as agricultural producers developing margins rich in flowers around their fields.
EU commissioner for environment, described the protection status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is necessary to confront this risk. Along with participating nations, the European Commission has established an EU-wide tracking system for pollinators based on the EU nature restoration law, which will aid in following our advancement. Now, we need to prioritize application and collaboration with member countries to preserve our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the initial Europe-wide study on hoverflies, a further vital group of pollinators. Released in 2022, it disclosed that thirty-seven percent of all hoverfly species in the European continent were facing extinction.
