The number of wild bee species in European nations confronting dying out has more than doubled in the last ten years, while the total of at-risk butterfly species has close to doubled.
This dire scenario for essential pollinating species was disclosed by research studies for the red list of threatened species, which established that at least over 170 bee varieties out of nearly two thousand were at risk of extinction in the European continent.
The count of butterflies facing extinction in European nations has grown from 37 to over sixty since the last study, performed over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural significance, pollinators like bees and butterfly species are essential supports for our well-being, our food supplies and our economies – supporting the fruits, vegetables and seeds that sustain us,” commented the IUCN’s director general. “The latest European red list evaluations reveal major obstacles, with risks mounting for butterfly species and vital native bee varieties.”
The reasons of the rapid recent declines are the persistent harm or degradation of living environments caused by intensive agriculture and land abandonment, draining wetlands, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators significantly raises the threat of disappearances in specific areas.
Climate change is also revealed to be a major threat: Over half of all threatened butterfly species in European nations are threatened by the climate crisis – about double the number as a previous decade.
Nearly ninety percent of plants that flower in the European continent depend on animal pollination, as per the lead coordinator of the wild bee assessment. “Sadly, non-managed bee colonies are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees disappear, many wild plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebees, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for aiding tree pollination such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type found only in the continent and the only species of this genus in the European continent, is now classified as severely threatened – the scientific classification most akin to dying out in natural habitats.
Butterfly species that are exclusively located on mountain tops are especially at risk to global heating as they must ascend higher as their habitats become more heated but eventually run out of space. In Spain’s southern region, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling butterfly are imperilled by extreme wildfires and drought.
Meanwhile, in the Arctic Circle, climate change is leading to the tree line to advance northwards by many meters each year, with bushes invading marsh and tundra. Hotter climates also mean caribou can not anymore cross the ice to graze Arctic meadows and maintain them clear. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The greatest living space for all these pollinating insects is bloom-filled grassy areas and that is declining quickly across European nations because of all these elements,” remarked a lead coordinator for the butterfly assessment. “The good news is that so many people are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to halt the drop in pollinating species by the year 2030, and they are going to have to initiate measures. There are landowners who are involved. We hope they can get the encouragements that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of measures for pollinating species which will not decrease crop yields – and may enhance it – such as farmers creating margins rich in flowers around their cultivated areas.
Jessika Roswall, characterized the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is required to address this danger. Together with member countries, the Commission of the European Union has put in place an European Union-wide observation system for pollinating species based on the EU nature restoration law, which will assist in monitoring our development. Now, we need to focus on implementation and partnership with participating nations to preserve our pollinators,” she said.
The issuance of the bee and butterfly assessments follows the first EU-wide assessment of hoverflies, an additional crucial pollinator group. Published in 2022, it disclosed that thirty-seven percent of all hoverfly varieties in the European continent were facing extinction.
