The number of native bee varieties in Europe confronting dying out has increased twofold over the past decade, whereas the count of endangered butterfly has nearly doubled.
This critical situation for essential pollinating species was unveiled by scientific assessments for the IUCN red list, which determined that at least one hundred seventy-two bee varieties out of 1,928 were facing extinction in Europe.
The number of butterfly species threatened with extinction in Europe has risen from over thirty-five to sixty-five since the earlier research, performed over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural value, pollinating insects like bees along with butterflies are lifelines for our health, our food chains and our economies – sustaining the fruits, veggies and seeds that sustain us,” said Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with threats mounting for butterfly species and vital non-managed bee varieties.”
The reasons of the quick recent decreases are the persistent harm or degradation of living environments caused by intensive agriculture and abandoned land, draining of wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The division of environments suitable for pollinators significantly raises the risk of local extinctions.
Climate change is also demonstrated to be a primary risk: Over half of all threatened butterflies in European nations are imperilled by the climate crisis – roughly twice as many as a ten years ago.
Up to nine out of ten of flowering plants in Europe depend on pollination by animals, according to Dr Denis Michez. “Unfortunately, wild bee groups are in severe drop and cannot readily be substituted by managed colonies,” he said. “If wild bees disappear, many native plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebee types, which play a crucial role in fertilizing crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the sole species of this genus in European nations, is now classified as critically at risk – the scientific category nearest to dying out in natural habitats.
Butterfly types that are exclusively located on high-altitude areas are particularly vulnerable to global warming as they must ascend higher as their habitats become warmer but eventually have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean, species such as the severely threatened Karpathos grayling are endangered by severe wildfires and drought.
In the meantime, in the Arctic Circle, global warming is causing the forest boundary to move north by tens of metres each year, with scrub encroaching on wetlands and tundra. Higher temperatures also mean caribou can not anymore cross the ice to feed on Arctic meadows and prevent them from overgrowing. Eight types of butterflies are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The greatest living space for all these pollinators is flower-rich grassland and that is declining quickly throughout the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member countries have to turn around the decline in pollinators by the year 2030, and they are going to have to start doing something. There are property owners who are involved. We hope they can get the motivations that will help them on their way.”
As stated by Martin Warren, there is “readily achievable actions” in terms of measures for pollinating species which will not lower food production – and could improve it – such as agricultural producers creating margins rich in flowers around their fields.
Jessika Roswall, characterized the protection status of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is needed to tackle this risk. Together with member countries, the EU Commission has put in place an EU-wide tracking system for pollinators based on the EU nature restoration law, which will aid in following our development. Now, we need to concentrate on application and partnership with participating nations to protect our pollinating species,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the pioneering Europe-wide evaluation of hoverflies, a further essential group of pollinators. Released in 2022, it disclosed that 37% of all hoverfly types in Europe were threatened with extinction.
