The number of non-managed bee varieties in the European continent confronting disappearance has over doubled in the last ten years, and the count of endangered butterfly species has nearly doubled.
This pressing issue for crucial pollinators was unveiled 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 over 1900 were facing extinction in European nations.
The count of butterflies at risk of extinction in European nations has grown from over thirty-five to sixty-five since the earlier research, conducted 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural value, pollinating species like bees and butterflies are lifelines for our well-being, our food systems and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” commented the IUCN director general. “The latest assessments of the European red list reveal serious challenges, with threats growing for butterfly species and essential non-managed bee types.”
The factors of the quick recent decreases are the continuing harm or degradation of habitats caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat greatly increases the threat of extinctions at local level.
Climate change is also shown to be a significant danger: Fifty-two percent of all endangered butterfly types in European nations are endangered by the climate emergency – approximately double the number as a decade ago.
Nearly ninety percent of plants that flower in the European continent require pollination by animals, as per the lead coordinator of the wild bee assessment. “Regrettably, wild bee colonies are in sharp decrease and are not easily replaceable by domesticated hives,” he said. “If non-managed bees die out, many native plants might be at risk too – of which flower-rich meadows and beautiful orchid species are just a couple of instances.”
Fifteen species of bumblebees, which have an essential part in pollinating legumes like peas, beans, peanuts and clover, and 14 types of cellophane bees, known for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the only species of this biological genus in European nations, is now evaluated as critically at risk – the scientific category nearest to disappearance 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 environments become more heated but in the end run out of space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean, types such as the highly at-risk Karpathos grayling are threatened by intense dry conditions and fires.
In the meantime, in the Far North, climate change is leading to the tree line to shift northward by tens of metres each year, with scrub encroaching on wetlands and tundra. Warmer conditions also mean Arctic deer can no longer cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The greatest environment for all these pollinators is bloom-filled grassy areas and that is declining quickly across the European continent because of all these factors,” remarked a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to turn around the drop in pollinating species by the year 2030, and they are going to have to start doing something. There are property owners who are involved. Let’s hope they can obtain the encouragements that will support them on their way.”
As stated by Martin Warren, there is “readily achievable actions” in terms of action for pollinators which will not lower agricultural output – and may enhance it – such as agricultural producers establishing margins rich in flowers around their fields.
EU commissioner for environment, characterized the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is necessary to tackle this danger. Along with participating nations, the European Commission has put in place an European Union-wide monitoring system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to prioritize implementation and cooperation with member countries to safeguard our pollinators,” she said.
The release of the assessments on bees and butterflies comes after the first European-wide study on hoverflies, another essential pollinating insect category. Released in twenty-twenty-two, it revealed that 37% of all hoverfly species in Europe were at risk of extinction.
