The total of non-managed bee species in European nations confronting dying out has more than doubled during the previous ten-year period, and the number of endangered butterfly types has almost doubled.
This pressing issue for crucial pollinating species was revealed by scientific assessments for the IUCN red list, which found that at least over 170 bee varieties out of over 1900 were threatened with extinction in Europe.
The count of butterflies at risk of extinction in Europe has increased from 37 to 65 since the earlier research, carried out 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural importance, pollinating species like bees and butterfly species are essential supports for our physical condition, our food chains and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” said the IUCN director general. “The newest assessments of the European red list reveal major obstacles, with threats growing for butterflies and crucial non-managed bee species.”
The factors of the quick recent decreases are the ongoing destruction or damage of habitats caused by intensive agriculture and abandoned land, wetland drainage, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of pollinator-friendly habitat significantly raises the threat of disappearances in specific areas.
Global warming is also demonstrated to be a primary risk: Over half of all at-risk butterfly species in European nations are endangered by the climate change crisis – approximately double the number as a previous decade.
As many as ninety percent of plants that flower 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 cannot readily be substituted by managed bee colonies,” he said. “If native bees die out, many native plants might be in danger as well – of which flower-rich meadows and attractive orchid varieties are just a few examples.”
15 varieties of bumblebee species, which play a crucial role in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for aiding tree pollination such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the European continent and the single type of this genus group in the European continent, is now assessed as critically endangered – the scientific category most akin to dying out in natural habitats.
Butterflies that are solely present on mountain peaks are highly susceptible to global heating as they have to climb upward as their environments become more heated but ultimately run out of space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean region, species such as the severely threatened grayling of Karpathos are imperilled by intense wildfires and drought.
At the same time, in the Arctic Circle, global warming is causing the tree line to move north by dozens of meters each year, with underbrush encroaching on bog and tundra. Warmer conditions also mean Arctic deer can no longer cross the ice sheets to browse northern grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The greatest habitat for all these pollinating insects is flower-rich grassland and that is vanishing rapidly in Europe because of all these reasons,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to halt the drop in pollinating insects by the year 2030, and they are going to have to begin taking action. There are land holders who are engaged. We hope they can obtain the motivations that will support them on their way.”
As stated by Warren, there is “readily achievable actions” in terms of measures for pollinating species which won’t reduce agricultural output – and could improve it – such as farmers establishing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Prompt and unified steps is required to address this threat. In collaboration with member countries, the Commission of the European Union has put in place an EU-wide monitoring system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and collaboration with member countries to protect our pollinating insects,” she said.
The issuance of the evaluations of bees along with butterflies is subsequent to the initial European-wide evaluation of hoverflies, a further crucial group of pollinators. Published in 2022, it showed that thirty-seven percent of all hoverfly species in Europe were at risk of extinction.
