The total of native bee varieties in the European continent facing extinction has more than doubled over the past decade, whereas the count of threatened butterfly has close to doubled.
This critical situation for crucial pollinators was unveiled by scientific assessments for the IUCN red list, which determined that at least 172 bee species out of 1,928 were threatened with extinction in Europe.
The total of butterfly types at risk of extinction in European nations has risen from over thirty-five to sixty-five since the previous assessment, conducted a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their visual charm and cultural value, pollinating insects like bees along with butterflies are lifelines for our well-being, our food chains and our economies – maintaining the fruits, vegetables and seeds that nourish us,” said the IUCN’s director general. “The newest European red list assessments reveal significant difficulties, with dangers increasing for butterflies and crucial wild bee species.”
The factors of the swift recent drops are the persistent harm or degradation of habitats caused by agricultural intensification and deserted farmland, draining wetlands, excessive grazing by animals, and the use of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the danger of extinctions at local level.
Climate change is also shown to be a major threat: Over half of all threatened butterfly species in Europe are endangered by the climate crisis – approximately twofold the amount as a ten years ago.
As many as 90% of blooming plants in Europe rely on pollination by animals, as per the lead coordinator of the wild bee assessment. “Regrettably, wild bee populations are in sharp decrease and cannot readily be substituted by managed bee colonies,” he said. “If native bees disappear, many wild plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebee types, which have an essential part in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for pollinating trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the only species of this genus in European nations, is now evaluated as severely threatened – the research category closest to disappearance in the wild.
Butterfly species that are solely present on mountain peaks are especially at risk to climate change as they have to climb upward as their environments become more heated but in the end have no room left. In the southern part of Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean area, types such as the highly at-risk Karpathos grayling are imperilled by intense wildfires and drought.
Meanwhile, in the Far North, global warming is causing the forest boundary to shift northward by tens of metres each year, with underbrush encroaching on marsh and tundra. Higher temperatures also mean reindeer can not anymore cross the ice sheets to feed on Arctic meadows and keep them open. Eight types of butterflies are threatened with extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The greatest living space for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly throughout European nations because of all these elements,” stated Martin Warren. “The encouraging aspect is that so many individuals are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states 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 interested. Let’s hope they can receive the encouragements that will assist them on their way.”
According to the coordinator, there is “easy opportunities” in terms of action for pollinating insects which will not decrease food production – and may enhance it – such as growers creating margins rich in flowers around their fields.
Jessika Roswall, characterized the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is necessary to tackle this danger. In collaboration with participating nations, the EU Commission has put in place an Europe-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our development. Now, we need to focus on execution and collaboration with member states to safeguard our pollinating species,” she said.
The publication of the evaluations of bees along with butterflies comes after the first EU-wide study on hoverflies, another essential group of pollinators. Issued in 2022, it showed that over one-third of all hoverfly species in Europe were threatened with extinction.
