The count of wild bee species in European nations facing disappearance has more than doubled during the previous ten-year period, and the count of threatened butterfly has nearly doubled.
This dire scenario for crucial pollinating species was unveiled by research studies for the red list of threatened species, which found that at least over 170 bee types out of over 1900 were threatened with extinction in European nations.
The count of butterflies facing extinction in the European continent has grown from over thirty-five to sixty-five since the previous assessment, performed 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural significance, pollinating insects like bees and butterflies are essential supports for our physical condition, our food supplies and our economies – sustaining the fruits, veggies and seeds that nourish us,” stated Grethel Aguilar. “The latest European red list evaluations reveal serious challenges, with dangers growing for butterfly species and vital native bee species.”
The causes of the swift recent drops are the persistent destruction or damage of natural habitats caused by agricultural intensification and land abandonment, wetland drainage, livestock overgrazing, and the use of fertilisers and pesticides including neonicotinoid chemicals. The division of habitat friendly to pollinators substantially boosts the danger of local extinctions.
Global warming is also demonstrated to be a primary risk: Over half of all threatened butterfly species in the European continent are threatened by the climate emergency – about twice as many as a decade ago.
Up to ninety percent of blooming plants in the European continent rely on insect pollination, as per the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees disappear, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebee species, which play a crucial role in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for pollinating trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the sole species of this genus group in European nations, is now evaluated as critically at risk – the research category nearest to extinction in the wild.
Butterfly species that are solely present on mountain peaks are particularly vulnerable to climate change as they have to climb upward as their habitats become more heated but ultimately run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean region, types such as the severely threatened grayling of Karpathos are threatened by intense dry conditions and fires.
In the meantime, in the Arctic Circle, global warming is leading to the forest boundary to shift northward by tens of metres each year, with bushes invading bog and tundra. Higher temperatures also mean reindeer can no more cross the frozen water to browse Arctic meadows and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest environment for all these pollinating species is flower-rich grassland and that is declining quickly across European nations because of all these reasons,” remarked a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals care now and there’s a lot more consciousness. Under the European Union nature restoration law, all member countries have to reverse the decline in pollinating species by 2030, and they are going to have to initiate measures. There are landowners who are interested. It is hoped they can get the incentives that will assist them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of steps for pollinators which will not lower food production – and might boost it – such as farmers establishing flower-rich margins around their fields.
EU commissioner for environment, characterized the protection status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is necessary to confront this threat. In collaboration with member states, the Commission of the European Union has established an EU-wide observation system for pollinating species based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to concentrate on execution and partnership with member countries to safeguard our pollinating species,” she said.
The issuance of the bee and butterfly assessments is subsequent to the pioneering European-wide study on hoverflies, a further essential group of pollinators. Published in 2022, it showed that over one-third of all hoverfly varieties in European nations were at risk of extinction.
