The count of wild bee types in European nations confronting extinction has more than doubled during the previous ten-year period, while the total of at-risk butterfly species has nearly doubled.
This pressing issue for essential pollinators was disclosed 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 nearly two thousand were at risk of extinction in Europe.
The total of butterfly species facing extinction in European nations has increased from 37 to 65 since the last study, conducted over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
“Beyond their aesthetic appeal and cultural importance, pollinators like bees and butterfly species are lifelines for our physical condition, our food systems and our economic systems – maintaining the fruits, vegetables and seeds that sustain us,” commented the IUCN director general. “The latest assessments of the European red list reveal significant difficulties, with risks increasing for butterfly species and essential wild bee species.”
The factors of the rapid recent declines are the ongoing destruction or damage of natural habitats caused by intensive agriculture and abandoned land, draining wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoids. The fragmentation of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.
Climate change is also shown to be a major threat: Fifty-two percent of all at-risk butterfly species in the European continent are imperilled by the climate emergency – roughly twofold the amount as a decade ago.
As many as 90% of flowering plants in the European continent require animal pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If native bees die out, many non-cultivated plants might be threatened too – of which flower-rich meadows and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebees, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, famous for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this genus in the European continent, is now classified as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterflies that are solely present on mountain tops are highly susceptible to global heating as they must ascend higher as their habitats become more heated but eventually have no room left. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean area, varieties such as the highly at-risk Karpathos grayling are endangered by extreme dry conditions and fires.
Meanwhile, in the Arctic Circle, climate change is causing the timberline to move north by many meters each year, with bushes taking over marsh and tundra. Warmer conditions also mean Arctic deer can not anymore cross the frozen water to graze Arctic meadows and maintain them clear. Eight types of butterflies are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest living space for all these pollinating species is flower-rich grassland and that is disappearing very fast throughout the European continent because of all these factors,” said Martin Warren. “The encouraging aspect is that so many people are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to halt the drop in pollinating insects by 2030, and they are going to have to initiate measures. There are property owners who are involved. Let’s hope they can obtain the motivations that will support them on their way.”
According to the coordinator, there is “easy opportunities” in terms of steps for pollinating insects which will not decrease agricultural output – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, characterized the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Urgent and collective action is needed to tackle this threat. In collaboration with member countries, the EU Commission has put in place an European Union-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and partnership with member states to protect our pollinating insects,” she said.
The publication of the assessments on bees and butterflies comes after the first EU-wide evaluation of hoverflies, a further essential pollinator group. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly types in European nations were at risk of extinction.
