The count of wild bee types in the European continent experiencing dying out has increased twofold during the previous ten-year period, while the number of at-risk butterfly types has almost doubled.
This critical situation for crucial pollinating species 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 types out of 1,928 were facing extinction in Europe.
The count of butterfly species at risk of extinction in Europe has increased from thirty-seven to sixty-five since the previous assessment, conducted a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural value, pollinating species like bees along with butterflies are lifelines for our health, our food systems and our economies – supporting the fruits, vegetables and seeds that feed us,” stated the IUCN director general. “The most recent assessments of the European red list reveal significant difficulties, with dangers growing for butterfly species and vital wild bee types.”
The reasons of the swift recent drops are the persistent harm or degradation of living environments caused by agricultural intensification and abandoned land, wetland drainage, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators significantly raises the risk of extinctions at local level.
Global heating is also shown to be a major threat: Over half of all threatened butterflies in European nations are imperilled by the climate emergency – roughly twofold the amount as a ten years ago.
Nearly ninety percent of flowering plants in the European continent rely on pollination by animals, as per the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in severe drop and cannot be easily replaced by managed colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be at risk too – of which flower-rich meadows and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebees, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee types, known for aiding tree pollination such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the continent and the only species of this genus group in European nations, is now assessed as critically endangered – the scientific category closest to extinction in the wild.
Butterflies that are only found on mountain tops are especially at risk to global warming as they have to climb upward as their habitats become hotter but in the end run out of space. In Spain’s southern region, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean region, types such as the severely threatened Karpathos grayling butterfly are threatened by intense dry conditions and fires.
In the meantime, in the Far North, global warming is resulting in the timberline to shift northward by tens of metres each year, with scrub invading wetlands and tundra. Hotter climates also mean reindeer can not anymore cross the ice to feed on northern grasslands and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The biggest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast throughout 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 European Union nature restoration law, all participating nations have to reverse the drop in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are land holders who are interested. We hope they can obtain the motivations that will support them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of action for pollinators which will not lower food production – and could improve it – such as growers establishing flower-rich margins around their fields.
the EU’s environment commissioner, described the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Urgent and collective action is needed to tackle this danger. Along with member countries, the European Commission has put in place an European Union-wide observation system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to concentrate on implementation and partnership with member countries to preserve our pollinators,” she said.
The release of the assessments on bees and butterflies comes after the pioneering Europe-wide study on hoverflies, an additional crucial group of pollinators. Issued in twenty-twenty-two, it disclosed that over one-third of all hoverfly species in the European continent were at risk of extinction.
