The number of wild bee types in European nations confronting extinction has over doubled during the previous ten-year period, whereas the total of endangered butterfly types has almost doubled.
This critical situation for vital pollinating species was unveiled by research studies for the red list of threatened species, which found that at least 172 bee species out of 1,928 were threatened with extinction in European nations.
The number of butterfly types facing extinction in European nations has increased from over thirty-five to over sixty since the last study, carried out over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural value, pollinating species like bees along with butterflies are crucial elements for our well-being, our food supplies and our economies – maintaining the fruits, vegetables and seeds that sustain us,” said the IUCN director general. “The newest European red list assessments reveal major obstacles, with threats growing for butterflies and crucial native bee species.”
The factors of the swift recent drops are the ongoing harm or degradation of living environments caused by intensive agriculture and land abandonment, wetland drainage, livestock overgrazing, and the utilization of pesticides and fertilisers including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Global warming is also shown to be a primary risk: 52% of all at-risk butterfly species in European nations are imperilled by the climate emergency – about twice as many as a ten years ago.
Nearly ninety percent of flowering plants in Europe require insect pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, wild bee colonies are in sharp decrease and cannot readily be substituted by managed bee colonies,” he said. “If non-managed bees die out, many non-cultivated plants might be threatened too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebees, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for aiding tree pollination such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the European continent and the single type of this biological genus in the European continent, is now evaluated as critically at risk – the scientific classification most akin to dying out in natural habitats.
Butterfly species that are only found on mountain tops are especially at risk to global warming as they must ascend higher as their living spaces become hotter but ultimately run out of space. In Spain’s southern region, the Nevada grayling butterfly 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 region, varieties such as the severely threatened Karpathos grayling butterfly are endangered by extreme dry conditions and fires.
In the meantime, in the Arctic Circle, global warming is leading to the tree line to move north by many meters each year, with bushes encroaching on wetlands and tundra. Higher temperatures also mean caribou can no longer cross the ice sheets to feed on Arctic grasslands and maintain them clear. Eight butterfly species are threatened with extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The largest habitat for all these pollinating species is grassland rich in flowers and that is disappearing very fast in Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to reverse the decrease in pollinating insects by the year 2030, and they are going to have to begin taking action. There are land holders who are involved. It is hoped they can get the incentives that will assist them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of action for pollinating insects which will not decrease agricultural output – and might boost it – such as growers establishing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is necessary to confront this risk. In collaboration with member countries, the European Commission has established an EU-wide observation system for pollinators based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to concentrate on implementation and cooperation with member states to protect our pollinating species,” she said.
The release of the bee and butterfly assessments follows the first EU-wide evaluation of hoverflies, another crucial pollinating insect category. Published in twenty-twenty-two, it disclosed that 37% of all hoverfly types in the European continent were facing extinction.
