The total of non-managed bee varieties in European nations facing disappearance has more than doubled over the past decade, whereas the number of endangered butterfly species has close to doubled.
This pressing issue for essential pollinating species was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee species out of nearly two thousand were threatened with extinction in Europe.
The total of butterfly types threatened with extinction in Europe has increased from over thirty-five to sixty-five since the earlier research, carried out 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural significance, pollinating species like bees and butterflies are lifelines for our health, our food chains and our economic systems – maintaining the produce, vegetables and seeds that sustain us,” stated the IUCN’s director general. “The most recent European red list evaluations reveal significant difficulties, with risks mounting for butterflies and crucial native bee types.”
The factors of the quick recent decreases are the continuing harm or degradation of natural habitats caused by agricultural intensification and abandoned land, draining of wetlands, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the danger of extinctions at local level.
Global warming is also demonstrated to be a significant danger: Fifty-two percent of all endangered butterflies in European nations are imperilled by the climate change crisis – approximately twice as many as a decade ago.
As many as ninety percent of blooming plants in the European continent rely on animal pollination, according to Dr Denis Michez. “Sadly, wild bee populations are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If native bees vanish, many wild plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
15 varieties of bumblebee types, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the sole species of this genus group in the European continent, is now classified as critically endangered – the research category nearest to disappearance in the wild.
Butterfly species that are only found on high-altitude areas are particularly vulnerable to climate change as they need to move uphill as their environments become more heated but eventually have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (exclusive to Europe) threatened with extinction.
In the Mediterranean, varieties such as the critically endangered Karpathos grayling butterfly are threatened by severe wildfires and drought.
At the same time, in the Arctic Circle, global heating is resulting in the forest boundary to shift northward by many meters each year, with underbrush taking over marsh and tundra. Warmer conditions also mean caribou can no longer cross the frozen water to graze Arctic meadows and maintain them clear. Eight butterfly species are facing extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The greatest environment for all these pollinators is bloom-filled grassy areas and that is disappearing very fast across European nations because of all these reasons,” remarked a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member countries have to turn around the decrease in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are property owners who are involved. Let’s hope they can receive the motivations that will support them on their way.”
According to Warren, there is “easy opportunities” in terms of measures for pollinators which will not lower crop yields – and could improve it – such as agricultural producers establishing margins rich in flowers around their farmland.
the EU’s environment commissioner, portrayed the preservation condition of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is necessary to tackle this threat. Together with participating nations, the European Commission has established an EU-wide tracking system for pollinators based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to focus on application and partnership with member states to preserve our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies comes after the pioneering Europe-wide evaluation of hoverflies, another essential group of pollinators. Released in 2022, it showed that 37% of all hoverfly species in the European continent were at risk of extinction.
