The count of non-managed bee varieties in European nations confronting disappearance has more than doubled over the past decade, while the total of endangered butterfly species has close to doubled.
This critical situation for essential pollinating insects was revealed by scientific studies for the red list of threatened species, which determined that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in European nations.
The total of butterfly species facing extinction in European nations has grown from 37 to sixty-five since the previous assessment, carried out 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural significance, pollinators like bees and butterflies are essential supports for our well-being, our food systems and our economic systems – sustaining the fruits, vegetables and seeds that feed us,” commented the IUCN director general. “The most recent European red list assessments reveal major obstacles, with dangers mounting for butterflies and vital non-managed bee types.”
The reasons of the swift recent drops are the ongoing damage or destruction of habitats caused by farming intensification and deserted farmland, wetland drainage, livestock overgrazing, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the threat of disappearances in specific areas.
Global warming is also demonstrated to be a major threat: Fifty-two percent of all threatened butterfly types in European nations are imperilled by the climate crisis – approximately twofold the amount as a ten years ago.
Nearly 90% of flowering plants in European nations depend on insect pollination, according to the wild bee assessment’s lead coordinator. “Regrettably, wild bee groups are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If wild bees die out, many wild plants might be threatened too – of which flower-rich meadows and beautiful orchid species are just a couple of instances.”
Fifteen species of bumblebee types, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for fertilizing trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the single type of this biological genus in Europe, is now assessed as critically at risk – the scientific classification most akin to disappearance in the wild.
Butterfly species that are only found on mountain peaks are highly susceptible to climate change as they need to move uphill as their habitats become more heated but in the end have no room left. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (solely present in Europe) facing extinction.
In the Mediterranean, types such as the critically endangered grayling of Karpathos are imperilled by extreme wildfires and drought.
At the same time, in the Far North, climate change is leading to the timberline to shift northward by many meters each year, with underbrush encroaching on bog and tundra. Warmer conditions also mean Arctic deer can no longer cross the ice sheets to graze Arctic meadows and keep them open. Eight butterfly species are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The biggest habitat for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly across European nations because of all these elements,” said Martin Warren. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to turn around the decline in pollinating species by the year 2030, and they are going to have to begin taking action. There are property owners who are interested. Let’s hope they can get the encouragements that will assist them on their way.”
As per the coordinator, there is “easy opportunities” in terms of action for pollinators which will not decrease agricultural output – and might boost it – such as farmers establishing flower-rich margins around their cultivated areas.
Jessika Roswall, described the protection status of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is required to address this danger. In collaboration with member countries, the EU Commission has established an EU-wide monitoring system for pollinators based on the EU nature restoration regulation, which will assist in monitoring our development. Now, we need to prioritize implementation and cooperation with member states to protect our pollinating insects,” she said.
The release of the assessments on bees and butterflies follows the pioneering European-wide evaluation of hoverflies, an additional essential pollinator group. Published in 2022, it disclosed that thirty-seven percent of all hoverfly species in European nations were facing extinction.
