The total of native bee types in European nations experiencing disappearance has more than doubled during the previous ten-year period, while the count of endangered butterfly types has nearly doubled.
This dire scenario for essential pollinators was unveiled by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of 1,928 were at risk of extinction in Europe.
The total of butterfly species facing extinction in the European continent has increased from 37 to over sixty since the last study, carried out over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural significance, pollinators like bees and butterfly species are lifelines for our physical condition, our food chains and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The newest European red list evaluations reveal serious challenges, with threats increasing for butterfly species and vital wild bee varieties.”
The factors of the rapid recent declines are the continuing harm or degradation of living environments caused by intensive agriculture and abandoned land, wetland drainage, excessive grazing by animals, and the use of fertilisers and pesticides including neonicotinoid pesticides. The division of environments suitable for pollinators substantially boosts the threat of disappearances in specific areas.
Global warming is also revealed to be a significant danger: 52% of all endangered butterfly types in the European continent are threatened by the climate emergency – roughly double the number as a decade ago.
As many as nine out of ten of blooming plants in the European continent require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee populations are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If non-managed bees disappear, many wild plants might be threatened too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebee types, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, recognized for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the only species of this genus group in European nations, is now classified as critically at risk – the scientific category nearest to extinction in the wild.
Butterfly types that are only found on high-altitude areas are particularly vulnerable to climate change as they need to move uphill as their living spaces become warmer but in the end run out of space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling butterfly are endangered by extreme wildfires and drought.
In the meantime, in the Arctic Circle, climate change is leading to the forest boundary to advance northwards by dozens of meters each year, with scrub invading wetlands and tundra. Warmer conditions also mean caribou can not anymore cross the ice sheets to graze Arctic grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The greatest environment for all these pollinating species is grassland rich in flowers and that is declining quickly in European nations because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The good news is that so many citizens care now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decrease in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are landowners who are involved. It is hoped they can get the incentives that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of steps for pollinating insects which will not lower food production – and may enhance it – such as growers creating flower-rich margins around their farmland.
EU commissioner for environment, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is needed to address this risk. In collaboration with participating nations, the EU Commission has established an Europe-wide observation system for pollinators based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to prioritize execution and cooperation with member states to preserve our pollinators,” she said.
The publication of the assessments on bees and butterflies comes after the initial European-wide study on hoverflies, another vital group of pollinators. Released in 2022, it showed that over one-third of all hoverfly species in the European continent were at risk of extinction.
