The number of wild bee varieties in Europe facing disappearance has more than doubled in the last ten years, while the total of at-risk butterfly has almost doubled.
This pressing issue for essential pollinating insects was unveiled by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which found that at least over 170 bee types out of over 1900 were facing extinction in the European continent.
The count of butterflies facing extinction in the European continent has increased from thirty-seven to over sixty since the last study, conducted over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural significance, pollinating species like bees along with butterflies are lifelines for our well-being, our food supplies and our economies – maintaining the produce, vegetables and seeds that sustain us,” said the IUCN director general. “The newest European red list evaluations reveal serious challenges, with dangers growing for butterflies and crucial native bee varieties.”
The causes of the rapid recent declines are the continuing harm or degradation of natural habitats caused by intensive agriculture and deserted farmland, draining of wetlands, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoids. The fragmentation of habitat friendly to pollinators significantly raises the danger of local extinctions.
Global warming is also demonstrated to be a primary risk: 52% of all at-risk butterfly species in European nations are endangered by the climate crisis – about twice as many as a previous decade.
Nearly 90% of flowering plants in the European continent depend on animal pollination, according to the lead coordinator of the wild bee assessment. “Unfortunately, native bee populations are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If native bees vanish, many wild plants might be at risk too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
Fifteen species of bumblebee species, which play a crucial role in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for fertilizing trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the only species of this biological genus in the European continent, is now classified as severely threatened – the research category nearest to extinction in the wild.
Butterfly species that are only found on mountain peaks are particularly vulnerable to global warming as they need to move uphill as their habitats become hotter but eventually run out of space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling are imperilled by extreme dry conditions and fires.
Meanwhile, in the Arctic Circle, climate change is resulting in the forest boundary to shift northward by many meters each year, with scrub encroaching on bog and tundra. Hotter climates also mean Arctic deer can no more cross the frozen water to browse Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinators is grassland rich in flowers and that is declining quickly across European nations because of all these elements,” remarked Martin Warren. “The good news 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 turn around the drop in pollinators by 2030, and they are going to have to initiate measures. There are property owners who are engaged. We hope they can obtain the encouragements that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of measures for pollinators which won’t reduce food production – and may enhance it – such as growers establishing bloom-filled edges around their cultivated areas.
EU commissioner for environment, described the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Prompt and unified steps is needed to tackle this risk. In collaboration with participating nations, the European Commission has put in place an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to concentrate on application and partnership with member countries to protect our pollinating insects,” she said.
The issuance of the bee and butterfly assessments follows the initial Europe-wide evaluation of hoverflies, another essential group of pollinators. Released in twenty-twenty-two, it revealed that over one-third of all hoverfly types in European nations were at risk of extinction.
